What Is Non-Nano Zinc Oxide Sunscreen and Why Does It Matter?

by Chiara Bonofiglio in Blog: Everything Under the Sun

What Is Non-Nano Zinc Oxide Sunscreen and Why Does It Matter? 

When choosing a mineral sunscreen, you may notice the term non-nano zinc oxide listed on the label. This ingredient is widely trusted by dermatologists because it provides effective broad-spectrum sun protection while remaining gentle enough for daily use, even for sensitive skin and children. 

What is non-nano zinc oxide? 

 

Zinc oxide is a mineral UV filter that protects skin by forming a barrier on the surface that helps reflect UVA and UVB rays. Unlike chemical sunscreens that absorb UV rays, mineral sunscreen works as a physical shield. 

Non-nano zinc oxide refers to zinc oxide particles that are larger than 100 nanometers. This size helps ensure the ingredient stays on the surface of the skin rather than being absorbed, making it a reassuring choice for families looking for everyday sun protection. 

 

Why choose a non-nano mineral sunscreen? 

Non-nano zinc oxide sunscreens are often preferred because they offer: 

• Broad spectrum UVA/UVB protection 
• Gentle protection for sensitive skin 
• A safe option for daily family use 
• Eco friendly  

• Mineral protection trusted by dermatologists  

For parents especially, mineral sunscreens with non-nano zinc oxide are often considered a reliable choice for children because of their gentle, non-irritating nature. 

 

MDSolarSciences’ mineral sunscreens feels different 

While traditional mineral sunscreens were known for thick textures or white residue, MDSolarSciences’ modern formulations have improved overall feel significantly. 

Our non-nano mineral SPF formulas are designed to feel lightweight, blend easily, and wear comfortably for everyday life. Our goal is to combine dermatologist-developed protection with elegant textures you actually enjoy wearing. 

Why MDSolarSciences uses non-nano zinc oxide 

Every mineral sunscreen in the MDSolarSciences collection uses non-nano zinc oxide because we believe sun protection should be both effective and wearable.

Your Memorial Day Weekend SPF Guide — Plus Our Biggest Sale of the Season

Your 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. Our biggest sale of the season is happening right now: 🌟 30% off sitewide 💎 FREE Hydrating Sheer Lip Balm SPF 30 in Crystal with orders $100+ No code needed for the 30% off — it applies automatically at checkout.

Why Moms Love MDSolarSciences (And Why We Love Moms Right Back)

Why 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
