How Often Should You Reapply Sunscreen? A Dermatologist's Guide to Getting It Right
The Short Answer You should reapply sunscreen every 80 minutes when you're outdoors, swimming, or sweating — and every 2 hours during general outdoor activity. If you're sitting inside by a window or going about your day indoors, reapplying once or twice is still a good idea, especially if you're near natural light for extended periods. But as with most things in skincare, the details matter. Let's break it down. Why Does Sunscreen Wear Off? Sunscreen — whether mineral or chemical — doesn't last forever on your skin. Here's why: UV exposure breaks it down. Chemical sunscreen filters absorb UV radiation and convert it to heat, which gradually depletes them. Even mineral sunscreens (zinc oxide and titanium dioxide) can be physically disrupted by sweat, water, and touch. Sweat and water wash it off. Even water-resistant formulas have limits. "Water resistant up to 80 minutes" means the SPF holds for 80 minutes of water exposure — after that, protection drops significantly. Touching your face removes it. Every time you wipe your face, apply makeup, or touch your skin, you're removing a layer of your SPF. It doesn't absorb into the skin and stay. Unlike moisturizers, sunscreen works on the surface — which means it needs to be refreshed. The Reapplication Rules by Situation ☀️ Outdoors — General Activity Every 2 hours, minimum. Set a timer if you need to. UV radiation is cumulative, and even on a partly cloudy day, up to 80% of UV rays reach your skin. 🌊 Swimming or Water Sports Every 80 minutes — even with water-resistant SPF. After toweling off, reapply immediately. Towel drying removes sunscreen just as effectively as water does. 🏃 Exercise or Heavy Sweating Every 80 minutes. Sweat dilutes and removes sunscreen quickly, especially around the hairline, forehead, and neck. 🚗 Driving or Sitting Near Windows Every 2 hours if you're exposed to sunlight through glass. UVA rays — the ones responsible for aging and long-term DNA damage — penetrate window glass. Your car window, your office window, your living room — all of it lets UVA through. 💻 Working Indoors If you're away from windows, reapplying once mid-day is sufficient. If you're near a window or sitting in direct indoor sunlight, treat it like outdoor exposure and reapply every 2 hours. 🌥️ Cloudy Days Don't skip reapplication. Clouds block visible light but not UV radiation. Up to 80% of UV rays pass through cloud cover — meaning you can burn and accumulate UV damage on overcast days just as on sunny ones. How Much Sunscreen Should You Reapply? Most people don't use enough — which means even if they reapply on time, they're not getting the full SPF protection listed on the bottle. For your face: About a nickel-sized amount (roughly ¼ teaspoon). For your body: About one ounce — a full shot glass worth — for complete coverage. Under-application is one of the most common reasons people feel like their sunscreen "isn't working." If you're applying too little, you're getting a fraction of the advertised SPF. Does Reapplying Over Makeup Work? Yes — with the right products. Reapplying liquid sunscreen over a full face of makeup isn't always practical, but there are options: Tinted SPF moisturizers — blend in over minimal makeup SPF sticks — easy to swipe over makeup without disturbing it At MDSolarSciences, our Mineral Tinted Crème SPF 30, our Mineral BB Crèmes and our Mineral Solar Sticks SOF 40 are lightweight enough to layer, making mid-day reapplication seamless even over skincare and light coverage. The Signs You Need to Reapply (Even If You Haven't Hit the 2-Hour Mark) You've been sweating heavily You've been in and out of water You've toweled off You've wiped your face You've applied powder or touched up your makeup Your skin feels warm or tight in the sun Any of these? Time to reapply. Common Reapplication Mistakes to Avoid ❌ Skipping reapplication because you applied a high SPF SPF 50 and SPF 100 still need to be reapplied. Higher SPF gives you more protection per application — it doesn't extend how long it lasts. ❌ Only reapplying to your face Your neck, ears, chest, hands, and the back of your neck are among the most commonly missed spots — and the most vulnerable to UV damage. Don't forget them. ❌ Waiting until you feel burned By the time your skin feels warm or starts to turn pink, UV damage has already occurred. Reapplication is preventive, not reactive. ❌ Skipping reapplication in winter UV radiation is year-round. UVA levels remain relatively constant throughout the year and can cause skin damage even in cold, grey weather. The Best Sunscreens for Easy Reapplication The best sunscreen is the one you'll actually reapply — which means it needs to feel good, look good, and fit into your real life. At MDSolarSciences, our formulas are designed to make reapplication something you actually want to do: Mineral Crème SPF 50 — lightweight, non-greasy, and gentle enough for sensitive skin. Reapplies beautifully over bare skin or minimal skincare. Mineral Tinted Crème SPF 30 — our most popular formula for daily wear. Blurs, hydrates, and protects in one step — easy to reapply mid-day. Quick Dry Body Spray SPF 40 — non-aerosol, broad spectrum spray for full-body coverage on the go. Dries fast, no rubbing required. Mineral KidStick SPF 40 — the easiest reapplication tool for kids. One swipe, no mess, no meltdown. KidSpray SPF 40 — non-aerosol kids spray for fast full-body reapplication at the pool or beach. All MDSolarSciences formulas are dermatologist-developed, clinically tested, and broad spectrum — so every reapplication counts. The Bottom Line Reapplying sunscreen isn't optional — it's the difference between protected skin and the illusion of protected skin. The rule is simple: every 80 minutes in water or heavy sweat, every 2 hours outdoors, and at least once mid-day if you're spending time near windows indoors. Set a reminder. Keep your SPF in your bag. Make reapplication a non-negotiable part of your routine. Your future skin will thank you. 👉 Shop MDSolarSciences broad spectrum SPF at mdsolarsciences.com

Learn moreDoes Sunscreen Stop You From Tanning? Here's What Actually Happens to Your Skin
If you've ever skipped SPF because you didn't want to "block" your tan, this one's for you. The Short Answer No, sunscreen does not completely stop you from tanning. But it does change how your skin responds to the sun — and understanding that difference might just change how you think about SPF forever. What Actually Causes a Tan? Before we get into sunscreen, let's talk about what a tan actually is. When your skin is exposed to ultraviolet (UV) radiation from the sun, your body triggers a defense mechanism: melanocytes (the cells responsible for pigment) produce more melanin to absorb and scatter UV rays. That darkening of the skin? That's your body trying to protect itself from damage. In other words, a tan is not a sign of health — it's a sign that your skin has been injured and is doing its best to cope. There are two types of UV rays to know: UVB rays — responsible for sunburn and surface-level skin damage UVA rays — penetrate deeper into the skin and are the primary driver of tanning, premature aging, and long-term DNA damage Both contribute to skin cancer risk. So What Does Sunscreen Actually Do? Sunscreen — especially broad spectrum SPF — works by absorbing, reflecting, or scattering UV radiation before it can penetrate your skin. It doesn't create an invisible force field that blocks 100% of UV rays. What it does is significantly reduce the amount of UV radiation that reaches your skin cells. Here's the math: an SPF 30 filters out approximately 97% of UVB rays. An SPF 50 filters out approximately 98%. That remaining 1-3% of UV exposure? That's still enough to trigger some melanin production — which means yes, you can still tan while wearing sunscreen. But here's the critical difference: that tan happens with dramatically less UV damage to your skin cells, less risk of sunburn, and far lower cumulative risk of skin cancer and premature aging. Can You Still Get a Glow With SPF On? Yes — and this is the part most people miss. Wearing sunscreen doesn't mean you'll come home from the beach looking exactly the same as when you left. It means you'll get less UV exposure, which slows down the tanning process and reduces the intensity of the tan. But slower and lighter doesn't mean zero. Many people who wear SPF consistently still develop a natural, gradual glow over a summer — just without the peeling, the sunburn, and the long-term skin damage that comes with unprotected sun exposure. If a bronzed look is your goal, there are safer ways to get there: Self-tanner or tanning drops layered under or over your SPF give you color without UV damage Tinted SPF and bronzing formulas create the appearance of warmth and glow while protecting your skin Gradual sun exposure with SPF can still build a light, natural tan over time — just without cooking your skin in the process Why Skipping SPF to Tan Faster Is Never Worth It We get it — the logic seems to make sense. Less sunscreen = more UV = faster tan. But here's what you're actually signing up for when you skip SPF: DNA damage — UV radiation causes direct damage to your skin's DNA, which accumulates over time and increases skin cancer risk Premature aging — UVA rays break down collagen and elastin, leading to wrinkles, sagging, and hyperpigmentation years before their time Uneven pigmentation — unprotected sun exposure is one of the leading causes of dark spots, melasma, and post-inflammatory hyperpigmentation Skin cancer — the most common cancer in the United States, and one of the most preventable with consistent sun protection The tan fades. The damage doesn't. The Reapplication Factor One reason people feel like sunscreen "isn't working" or is stopping them from tanning is actually a reapplication issue. Sunscreen breaks down with sun exposure, sweat, and water — which is why dermatologists recommend reapplying every 80 minutes during outdoor activity, or immediately after swimming or sweating. If you apply SPF in the morning and spend six hours outside without reapplying, you're spending most of that time with little to no protection. And at that point, any tanning (or burning) you experience has nothing to do with sunscreen stopping it — it's because the sunscreen is no longer doing its job. Tips for keeping your SPF working all day: Apply generously — most people use far less than the recommended amount (about a shot glass worth for the body, a nickel-sized amount for the face) Reapply every 80 minutes outdoors Use water-resistant SPF if you're swimming or sweating Don't forget ears, the back of the neck, hands, and feet What Dermatologists Actually Say Dermatologists are unequivocal on this: there is no such thing as a safe tan from UV exposure. Any color change from the sun is evidence of skin damage. The American Academy of Dermatology recommends wearing broad spectrum SPF 30 or higher every single day — rain or shine, indoors or out — because UV rays penetrate clouds and windows. At MDSolarSciences, we were founded on this exact mission. Our brand was built around the belief that protecting your skin from the sun is one of the single most powerful things you can do for your long-term health — and that great SPF should feel good enough that you actually want to wear it every day. The Bottom Line Sunscreen doesn't stop you from tanning — but it does protect you while you do. It slows down and reduces the intensity of UV-driven color change while dramatically cutting your risk of sunburn, premature aging, and skin cancer. The glow you want is still achievable. The damage that comes with unprotected sun exposure is not worth it. Wear your SPF. Reapply. And if you want a deeper tan, reach for a self-tanner — your future skin will thank you. MDSolarSciences offers a full range of dermatologist-developed, broad spectrum mineral and chemical SPF formulas for face, body, and kids — designed to feel like skincare, not sunscreen.

Learn moreBEMT Is Coming to the USA — Here's What You Need to Know
You might've heard the news. The FDA just approved the first new sunscreen ingredient in over 25 years — and it's a big deal for everyone who cares about sun protection. Here's what you need to know, what it means for your routine, and how to navigate your SPF choices right now. What Is BEMT? BEMT stands for Bemotrizinol — a chemical UV filter that has been used safely in sunscreens across Europe and Asia since 1999. If you've ever used a K-beauty SPF or picked up a French pharmacy sunscreen on vacation and thought "why doesn't this exist in the US?" — bemotrizinol is a big part of the reason those formulas felt so different. The FDA finalized its approval of bemotrizinol, the first new ultraviolet filter in more than 25 years, deemed a safe and effective active ingredient in U.S. sunscreens. Here's the quick breakdown: BEMT = Bemotrizinol — a chemical (non-mineral) UV filter Safe and effective — data submitted to the FDA confirms that at concentrations up to 6%, bemotrizinol is minimally absorbed through the skin, with average absorption levels below the concentration the FDA considers indicative of systemic exposure 27 years of global use — used in Europe and Asia since 1999 under brand names including Tinosorb® S and Parsol® Shield Photostable — unlike avobenzone, BEMT doesn't break down in sunlight, meaning it stays effective all day Strong UVA protection — it specifically closes the UVA gap that has long been a weakness in American sunscreens Why Is This Such a Big Deal? The core issue is UVA protection. UVA rays are the ones responsible for deep skin damage — premature aging, collagen breakdown, and a primary contributor to skin cancer. Traditional U.S. sunscreens excel at blocking UVB rays, which cause visible sunburns, but routinely fail to shield against deep-penetrating UVA rays. Until now, the only non-mineral ingredient in US sunscreens that provided meaningful UVA coverage was avobenzone — and avobenzone is chemically unstable, meaning it breaks down when exposed to sunlight. BEMT solves that problem with a stable, long-lasting UVA filter that doesn't degrade. Even with bemotrizinol added to the mix, U.S. sunscreen formulators will have access to 16 approved UV filters — while European formulators have access to approximately 30. So while this is a meaningful step forward, there's still work to be done. So — Is BEMT Better Than Mineral SPF? Here's the honest answer: it depends on your skin and what matters most to you. Whether a chemical or mineral SPF is the best choice is highly personal. Both protect. Both have trade-offs. Here's how they compare: Mineral SPF ✓✓✗ ✓ Physical filter — sits on top of skin and physically deflects UV rays rather than absorbing them ✓ Can be reef-safe — zinc oxide is one of the most reef-friendly UV filters available, and when formulated without oxybenzone and octinoxate, mineral sunscreens are ocean-safe ✗ Can leave a white cast — this is the biggest complaint about mineral SPF, though it depends entirely on the formula. Modern mineral formulas like ours are engineered to minimize white cast significantly Best for: Sensitive skin, rosacea, acne-prone skin, babies and children, people who want the most stable and balanced UVA/UVB protection, and anyone who prefers a physical barrier Chemical SPF (including BEMT) ✓✓✗ ✓ Absorbs into skin — chemical filters work by absorbing UV rays and converting them to heat, which means they go on invisibly ✓ Clear — no white cast — this is the biggest advantage of chemical SPF, especially for deeper skin tones where mineral formulas have historically been more visible ✗ Can sometimes feel oily — depending on the formula, some chemical SPFs have a heavier or greasier feel, particularly in heat and humidity Best for: People who have struggled with white cast, those who prefer an invisible finish, and anyone who wants the lightest possible texture on skin Where Does MDSolarSciences Stand? At MDSolarSciences, our foundation has always been mineral SPF. EWG's top recommendation for daily use remains mineral sunscreens formulated with zinc oxide, which provide the most stable and balanced broad-spectrum UVA and UVB protection currently available. Our formulas are built on 100% mineral actives — zinc oxide as the core UV filter — engineered by our founder Dr. Robert Friedman, one of the pioneers of the ABCDE's for melanoma detection. Every formula we make is dermatologist-developed and rooted in skin cancer prevention. That said, we believe in empowering you to make the right choice for your skin. The best sunscreen is always the one you'll actually wear — every single day. For mineral SPF: Our Mineral Crème SPF 50, MD Mineral BB Crème SPF 50, and Mineral Tinted Crème SPF 30 are formulated to minimize white cast while delivering maximum broad-spectrum protection. For kids: Our Mineral KidCrème SPF 50 and Mineral KidStick SPF 40 use 100% mineral actives that are safe from 6 months+ and gentle enough for the most sensitive skin. What to Do Right Now BEMT products won't hit US shelves immediately. Today's approval of bemotrizinol triggers 18 months' exclusive marketing rights in the U.S. of Parsol Shield, a proprietary bemotrizinol formulation. After that period, other manufacturers may use it in their formulations, driving broader availability and more competitive pricing. In the meantime, here's how to choose the best sunscreen for your skin today: If you want maximum protection and have sensitive skin: Choose a mineral SPF with zinc oxide. It's the most stable, most trusted, and most dermatologist-recommended option currently on shelves. If white cast has stopped you from wearing SPF: Look for modern mineral formulas engineered for minimal white cast — or a hybrid formula. The right formula makes all the difference. For your kids: Mineral actives are still the recommendation for babies and children. Safe, gentle, and effective from day one. The most important rule of all: The best SPF is the one you actually wear. Daily. Rain or shine. Indoors and out. ☀️ Explore MDSolarSciences' full collection of dermatologist-developed SPF skincare at mdsolarsciences.com Sources: Environmental Working Group (EWG), FDA Press Announcement June 2026
Learn moreThe Spray That Goes Everywhere You Do: Why MDSolarSciences Quick Dry Sprays Belong in Every Bag
You applied sunscreen before leaving the house. You always do. But here's the thing nobody talks about enough: that first application wears off — and reapplication is just as important as the first coat. The walk to the farmers market. The afternoon hike. The stroll around the neighborhood with the stroller. These are exactly the moments when shoulders, arms, and the back of your neck are soaking up UV rays — often without you even thinking about it. And these are the moments a quick, portable, 360° spray was made for. Meet the two sprays we think belong in every bag this summer. Why Reapplication Matters More Than You Think SPF isn't a set-it-and-forget-it step. Broad spectrum sunscreen protection breaks down with sun exposure, sweat, and time — and the American Academy of Dermatology recommends reapplying every two hours during outdoor activity. The challenge? Reapplication is inconvenient. Lotions require rubbing. Sticks are great for faces but miss larger areas. And most sprays are aerosol — which means they're pressurized, can't be used upside down, and are often restricted in certain travel and outdoor settings. That's exactly the problem our sprays solve. Quick Dry Body Spray SPF 40 — For You The spray that works from every angle. Our Quick Dry Body Spray SPF 40 is a non-aerosol pump spray with a 360° nozzle — meaning it sprays in any direction, including completely upside down. That's not a small thing. It means you can actually reach your own back, your shoulders, the back of your legs — every spot that gets exposed on a walk, a hike, or a bike ride and that you'd normally miss. Why it belongs in your bag: Tuck it into your tote, your hiking pack, your stroller bag, or your beach bag. At 6 fl oz it's the perfect size to have on hand for the moments that sneak up on you — the afternoon that turned into an outdoor lunch, the walk that went longer than expected, the shoulders that got more sun than you realized. What it does: Broad spectrum SPF 40 — protects against both UVA and UVB rays Water and sweat resistant for up to 80 minutes Quick-dry formula — no grease, no residue, no waiting around 360° nozzle — sprays upside down for full-body coverage Antioxidant-enriched with Vitamin C and Indian Gooseberry Non-aerosol — travel-friendly (checked bag), reef-friendly, and safe for outdoor use The moments it's made for: Your morning walk. The hiking trail. The beach. The pool. The soccer sideline. Any time you're outside and your first application of the day has worn off — this is the spray that makes reapplication fast enough to actually happen. Note: Our Quick Dry Body Spray is not mineral-based — it uses a lightweight chemical broad spectrum formula designed for fast, even coverage over large body areas. Kids Quick Dry Spray SPF 40 — For Them The spray that actually keeps up with kids. Reapplying sunscreen on a child who wants to keep playing is one of the great parenting challenges of summer. You need something fast. Something that works. And something gentle enough for the skin they're in. Our Kids Quick Dry Spray SPF 40 is a non-aerosol pump spray specifically formulated for children — gentle enough for sensitive skin, fast enough for kids who won't stand still, and effective enough for real outdoor days. Why it belongs in the diaper bag: If you have a baby, a toddler, or a school-age child spending time outdoors — the diaper bag, the school bag, or the stroller's storage basket is exactly where this should live. Playground reapplication. Post-swim coverage. Mid-hike arms and shoulders. The spray makes it fast enough to actually do it in the moment, not just plan to do it. What it does: Broad spectrum SPF 40 — real protection for real outdoor days Water resistant up to 80 minutes — pool days, beach days, active play 360° nozzle — reaches shoulders, backs, and every spot kids miss Non-aerosol pump — no harsh propellants, travel and outdoor safe Gentle formula — suitable for kids from 6 months+ Quick-dry — no waiting, no fuss, back to playing in seconds Fragrance-free — gentle for sensitive skin The moments it's made for: The stroller walk where tiny arms are catching direct sun. The hike where little shoulders are completely exposed. The pool day that goes longer than expected. Summer camp reapplication. Vacation days where you're outside from morning to night. This is the spray that makes staying protected feel effortless — for you and for them. Note: Our Kids Quick Dry Spray is not mineral-based — it uses a broad spectrum formula developed with gentle, kid-appropriate ingredients. For a mineral option for kids, our Mineral KidCrème SPF 50 and Mineral KidStick SPF 40 are the perfect complement. The Shoulder Problem Nobody Talks About Here's something worth saying out loud: your shoulders are one of the most UV-exposed and most under-protected areas on your body. When you're walking, hiking, or pushing a stroller, your shoulders are at a direct angle to the sun for extended periods. Most people apply lotion to their arms and legs but don't reach their own shoulders, upper back, or the back of their neck — especially when they're alone. A 360° spray solves this completely. Point it over your shoulder, press, done. It takes under ten seconds and it's one of the most meaningful SPF habits you can build into your outdoor routine. The On-the-Go SPF Edit For the diaper bag: Kids Quick Dry Spray SPF 40 + Mineral KidStick SPF 40 for faces. Two products. Every inch of your child covered. Reapplication ready wherever you are. For the hiking pack: Quick Dry Body Spray SPF 40 for body reapplication + Solar Stick SPF 40 for face touch-ups. Lightweight, packable, and effective for a full day on the trail. For the beach bag: Both sprays for the whole family. Fast to apply, water resistant, and 360° coverage means nobody's shoulders get missed at the shoreline. For the stroller bag: Kids Quick Dry Spray SPF 40 tucked in and ready for the moments when the walk goes longer than expected or the afternoon sun gets stronger than you planned. Sun protection shouldn't stop when you leave the house. It should travel with you — into the hiking trail, onto the playground, down the neighborhood street, and everywhere in between. That's what these sprays are for. 🤍☀️ Shop the Quick Dry Body Spray SPF 40 and Kids Quick Dry Spray SPF 40 at mdsolarsciences.com
Learn moreWhy Reef Safe Mineral Sunscreen Is the Best SPF You Can Wear on World Ocean Day (And Every Day)
Every June 8th, World Ocean Day reminds us that the choices we make on land have a direct impact on the ocean. One of the simplest swaps you can make if swimming in the ocean this summer? Switching to a reef safe mineral sunscreen. Here's what that means, why it matters, and how MDSolarSciences makes it easy for the whole family. The Sunscreen-Ocean Connection You Need to Know You've probably heard the term "reef safe sunscreen" — but what does it actually mean? Certain chemical sunscreen filters, most notably oxybenzone and octinoxate, have been shown to contribute to coral bleaching and disrupt marine ecosystems. When you swim, sweat, or rinse off, those ingredients wash into the water and can accumulate in reef environments over time. Mineral sunscreens, on the other hand, use zinc oxide and titanium dioxide as their active ingredients — physical blockers that sit on top of the skin and deflect UV rays rather than absorbing them. These ingredients are widely considered safer for marine life, which is why reef safe mineral sunscreen has become the gold standard for ocean-conscious sun protection. At MDSolarSciences, our mineral formulas are proudly reef safe — and dermatologist-developed to perform just as beautifully as they protect. Not All Sunscreens Are Created Equal — Here's What to Look For When shopping for the best mineral sunscreen, especially for daily wear or beach days, here's what matters: Zinc oxide as the active ingredient — the most effective and reef-friendly mineral filter Broad spectrum SPF 30 or SPF 50 — protects against both UVA and UVB rays No oxybenzone or octinoxate — the two most common reef-damaging chemical filters Water resistant up to 80 minutes — especially important for ocean and pool days Dermatologist developed and tested — because your skin deserves clinical-grade protection MDSolarSciences checks every single one of these boxes across our mineral lineup — for adults and kids alike. Our Reef Safe Mineral Sunscreens for Adults Hydrating Mineral Sunscreen That Feels Like Skincare If you've ever skipped sunscreen because it felt heavy, greasy, or left a white cast — our mineral formulas were made to change your mind. We've spent years perfecting lightweight mineral SPF that wears like a premium skincare product, not an afterthought. What to try: Mineral Crème SPF 50 — a hydrating mineral sunscreen with antioxidants, ideal for sensitive skin and daily wear. Non-greasy, non-comedogenic, and dermatologist recommended. Mineral Tinted Crème SPF 30 — our fan-favorite tinted mineral sunscreen that doubles as a lightweight tinted moisturizer with SPF. Blurs, hydrates, and protects in one step. No white cast. Mineral BB Crème SPF 50 — the ultimate mineral BB cream SPF 50 for those who want buildable coverage with broad spectrum protection. Think of it as your new spf tinted moisturizer. HSA and FSA Eligible Sunscreen — Yes, Really Did you know many of our SPF products qualify as HSA/FSA eligible SPF products? Sunscreen with broad spectrum SPF 15 or higher qualifies as a medical expense under IRS guidelines — which means you can use your pre-tax health savings dollars to stock up. Whether you're looking for FSA sunscreen, HSA suncare, or an HSA hydration cream that doubles as your daily moisturizer with SPF, MDSolarSciences has options that work with your benefits. It's one of the smartest ways to invest in your skin — and the ocean. Reef Safe Kids Sunscreen for World Ocean Day If you're heading to the beach with little ones this summer, kids reef safe mineral sunscreen isn't just a nice-to-have — it's a must.

Learn moreYour Memorial Day Weekend SPF Guide — Plus Our Biggest Sale of the Season
Memorial Day weekend is officially here — and with it comes the first real taste of summer. Longer days, warmer temperatures, more time outside, and the highest UV index we've seen all year. Whether you're hosting a backyard barbecue, heading to the beach, hitting the hiking trails, or simply enjoying a long weekend with the people you love — this is the weekend that sets the tone for your entire summer skin health. And we want to make sure you're covered. ☀️ The SPF Moments You Can't Skip This Weekend The Barbecue Outdoor gatherings mean hours of sun exposure — often without even realizing it. You're moving around, laughing, eating, and the last thing on your mind is reapplying sunscreen. Build it into your routine before you step outside and keep a Solar Stick SPF 40 nearby for easy touch-ups throughout the day. Swipe it on your nose, ears, and hands — the spots people always forget. The Beach or Pool Water reflects UV rays, which means your exposure is significantly higher near water than on land. Water-resistant SPF is non-negotiable here. Our Quick Dry Body Spray SPF 40 is your best friend — it sprays upside down so you can actually reach your back, dries in seconds, and holds up for 80 minutes of water resistance. Reapply every two hours and every time you towel off. The Long Drive UVA rays — the ones responsible for aging and skin cancer — penetrate car windows. That means your face, hands, and arms are exposed every single time you're in the car. Don't skip face SPF just because you're not "outside." Our Daily Perfecting Moisturizer SPF 30 takes 30 seconds to apply and protects you from dashboard to destination. The Kids Memorial Day is peak outdoor time for little ones — playgrounds, pools, backyard sprinklers, sports. Apply sunscreen before they head out and reapply every two hours without fail. Our Mineral KidCrème SPF 50 is gentle enough for babies 6 months+ and fast enough for the ones who won't stand still. Follow up with the Mineral KidStick SPF 40 for faces and easy reapplication on the go. The Golden Hour Hangout Evening sun still carries UV — especially in late May when the sun sets later. Don't assume you're safe once the afternoon ends. Keep a lip balm and a stick handy for the evening stretch. Our Hydrating Sheer Lip Balm SPF 30 in Crystal is the perfect finishing touch for the golden hour glow. 💎 Don't Forget to Reapply The most common Memorial Day sunscreen mistake? Applying once in the morning and considering yourself protected all day. SPF needs to be reapplied every two hours of sun exposure — and immediately after swimming or heavy sweating. Set a reminder on your phone. Keep a stick in your bag. Make it a family habit before anyone hits the water. It's the smallest habit with the biggest long-term payoff. The MDSolarSciences Memorial Day Sale Is Live 🎉 Now for the good news — because protecting your skin should never break the bank.

Learn moreWhy Moms Love MDSolarSciences (And Why We Love Moms Right Back)
There's a reason moms have always been our most passionate advocates. It's not because we asked them to be. It's because when you find a sunscreen that actually works — one that goes on fast, doesn't fight your kids, doesn't feel heavy on your own skin, and that you genuinely trust — you tell everyone. That's what moms do. They share what works. And we've spent years making sure MDSolarSciences is worth sharing. Here's why moms love us — and why, honestly, the feeling is completely mutual. 🤍 1. Because Their Kids' Skin Deserves the Best Ask any dermatologist what the single most important thing a parent can do for their child's long-term skin health is, and they'll say the same thing: daily mineral SPF, starting early. About 23% of a person's lifetime UV exposure happens before age 18. The habits built now protect the skin they'll live in for decades. That's not a small thing — and moms know it. Our entire Kids line was built around one goal: make sun protection so easy and so gentle that it actually gets used every single day. Mineral KidCrème SPF 50 is our full-coverage kids face and body crème — 100% mineral actives, fragrance-free, dermatologist-developed, and safe from 6 months+. It absorbs quickly, leaves no white cast, and doesn't sting sensitive eyes. The kind of formula that makes the morning routine feel manageable rather than like a negotiation. Mineral KidStick SPF 40 is the no-mess, no-fight answer to the spots kids always miss — ears, nose tip, back of the neck, hands. One swipe, no rubbing required. It lives in every diaper bag, school bag, and tote we've ever seen a mom carry. KidSpray SPF 40 is for the ones who won't stand still. A non-aerosol pump that covers arms, legs, and backs in seconds. 80-minute water resistance. Safe from 6 months+. The beach bag, pool bag, and playground bag essential. All three are fragrance-free and made without the harsh chemicals that parents worry about most. 2. Because Their Own Skin Matters Too Here's something we've noticed: moms are always the last to put on sunscreen. They do the kids first, then forget themselves entirely. We're here to change that — because protecting your own skin matters just as much. Daily Perfecting Moisturizer SPF 30 was made for the 30-second morning routine. Hyaluronic acid, niacinamide, Vitamin C, ceramides, and peptides — plus broad-spectrum SPF 30 — in one lightweight step. It feels like your favorite moisturizer. It works like a full skincare routine. It's the product busy moms reach for every single morning. Mineral Crème SPF 50 is for the days when you want maximum protection without compromising on feel. A cult-favorite with a natural matte finish, zero white cast, and a weightless texture that wears beautifully under makeup. Broad-spectrum SPF 50 with antioxidants that protect and restore. Dermatologist-developed and genuinely beloved. Advanced Hydration Crème is the PM counterpart — a deeply nourishing moisturizer with ceramides, hyaluronic acid, and calming botanicals that restores skin overnight. Because protection during the day and restoration at night is the routine dermatologists actually recommend. 3. Because SPF Can Be Beautiful Moms told us early on: they didn't want to choose between sun protection and looking good. So we made sure they never have to. BB Crème SPF 50 replaces your foundation step entirely. Sheer, weightless, antioxidant-rich coverage in Light, Medium, Dark and Deep. A lit-from-within finish that looks like great skin — because it is protecting great skin. Mineral Tinted Crème SPF 30 is the sheer tinted SPF that blurs, evens, and protects in one silky step. The product that lives on bathroom counters everywhere. Cheek Crème SPF 30 — the world's best SPF blush. Buildable, blendable color in Magic Hour (warm rose) and Heat Wave (peachy coral) with broad-spectrum mineral protection baked in. A product that moms have been telling their friends about since the day it launched. Hydrating Sheer Lip Balm SPF 30 in 7 gorgeous shades (Dream, Spice, Bare, Crystal, Blush, Shimmer, Ruby) — because lips are one of the most sun-exposed and most forgotten areas on the face. This is the SPF step that feels like a treat. 4. Because Easy Is Everything We don't need to tell moms that time is precious. They already know. Everything in our line is designed to work fast, feel good, and ask as little of you as possible. No white cast to rub in. No greasy residue to wait for. No stinging, no heaviness, no fighting with your kids to get it on. The Solar Stick SPF 40 is proof of that philosophy. Drop it in your bag. Pull it out at the playground, the soccer game, the beach. Swipe it on faces, ears, hands — yours and theirs. Three seconds. Done. No mess, no re-application drama. The Gleam + Glow SPF 50 is the final step that makes the whole routine feel worth it — a luminous, skin-perfecting SPF that gives a beautiful healthy glow while protecting every inch of skin it touches. 5. Because We Were Built Around Trust MDSolarSciences was founded by Dr. Robert Friedman — one of the pioneers of the ABCDE's for melanoma detection. Sun protection isn't a trend for us. It's a mission. Every formula is dermatologist-developed. Every active ingredient is intentional. Every texture is tested until it's something you actually want to wear. Moms have trusted us with the most important thing in their lives — their children's skin. We don't take that lightly. We never will. The Bottom Line Moms love MDSolarSciences because it works, because it's safe, and because it makes protecting the whole family feel effortless rather than exhausting. And we love moms because they've always been our most honest, most passionate, most powerful advocates — long before influencer marketing was even a concept. You've always been our OG. 🤍 Explore the full MDSolarSciences collection for moms, babies, and families at mdsolarsciences.com
