Stand in the sunscreen aisle for five minutes and you'll see it everywhere this summer... "reef safe," "clean," "non-toxic," or "EWG Verified." Some of these mean something specific. Others mean almost nothing at all. If you've ever picked up a bottle and wondered which claims to actually trust, you're asking exactly the right question.
This is something we talk about often at Flourish, because your skin is your body's largest organ, and what you put on it matters just as much as what you put in it. So let's walk through what EWG Verification actually means, how mineral and chemical sunscreens differ, and how to choose sun protection you can feel confident about this summer.
The short answer: EWG Verified means a product meets the Environmental Working Group's strict standards for ingredient safety and full transparency, with no ingredients on their list of chemicals of concern. Mineral sunscreens (zinc oxide or titanium dioxide) sit on top of the skin and physically reflect UV rays, while chemical sunscreens absorb into the skin to filter UV rays, which is why many clean beauty advocates prefer mineral formulas. |
What EWG Verification Actually Mean?
The Environmental Working Group (EWG) is a nonprofit research organization that has spent over two decades evaluating personal care products, cleaning products, and food for ingredient safety. Their EWG Verified mark is one of the more rigorous certifications in the clean beauty space, and it means a product meets specific criteria:
Full ingredient disclosure, nothing hidden behind vague terms like "fragrance"
No ingredients on EWG's list of chemicals linked to health concerns
Manufacturing practices that meet strict safety standards
Formulation that avoids EWG's "Dirty Dozen" ingredients of concern
This is different from a brand simply saying a product is "natural" or "clean," terms that have no legal definition and aren't independently verified by anyone. EWG Verification means an outside, science-based organization actually checked, which is a meaningfully higher bar than a label alone.
This matters because sunscreen regulation in the United States hasn't kept pace with research. Many ingredients still allowed in sunscreens today were approved decades ago, before some of the newer absorption and hormone studies existed. A third-party verification system helps fill that gap for anyone who wants a more current, evidence-based answer than the label alone provides.
Mineral vs. Chemical Sunscreen: What's the Real Difference?
Most sunscreens on the market fall into one of two categories, and understanding the difference helps explain why we chose the product we did.
Chemical Sunscreens
Chemical sunscreens use ingredients like oxybenzone, avobenzone, or octinoxate to absorb UV radiation before it damages the skin. They tend to feel lightweight and blend in easily, which is part of why they're so common. The tradeoff is that these ingredients are absorbed into the skin, and several have been detected in bloodstream studies at levels the FDA has said warrant further safety research. Oxybenzone in particular has also raised concerns for coral reef health, which is where "reef safe" labeling comes from.
Mineral Sunscreens
Mineral sunscreens use non-nano zinc oxide or titanium dioxide, which sit on top of the skin and act like a physical shield, reflecting UV rays away rather than absorbing them. They tend to be thicker and can leave a slight cast, though modern formulas like Babo Botanical have improved that significantly. Because they work on the surface rather than being absorbed, mineral sunscreens are generally the preferred choice for babies, pregnant women, and anyone wanting to minimize what's absorbed into the body. They're also naturally reef safe, since there's no oxybenzone or octinoxate involved.
Is SPF Alone Enough Information?
Not quite. SPF only tells you about protection from UVB rays, the ones primarily responsible for sunburn. It doesn't tell you anything about UVA protection, which penetrates more deeply and plays a bigger role in premature skin aging. This is why "broad-spectrum" matters just as much as the SPF number itself... it confirms a sunscreen is doing both jobs, not just the one most people think about.
A high SPF number on a chemical formula also isn't automatically a safer choice than a lower SPF mineral formula. Coverage and ingredient safety are two separate questions, and it's worth considering both.
Why This Matters for Your Whole Family
Sunscreen isn't a once-a-summer purchase, it's something most of us reapply constantly, on ourselves and on our kids, for months at a time. That frequency is exactly why ingredient quality matters so much here. A product you use once won't meaningfully affect your body's overall load of absorbed chemicals. A product you reapply several times a week, all summer long, at the beach, the ballfield, and every backyard afternoon in between, absolutely can.
This is the same standard we hold for everything we recommend at Flourish... your skin is your body's largest organ, and what goes on it deserves the same thoughtfulness as what goes in it. Children in particular have a higher skin surface area relative to body weight, which is one reason so many pediatric and dermatology sources specifically point toward mineral formulas for younger kids.
How to Read a Sunscreen Label Like You Know What You're Looking At
Look for zinc oxide or titanium dioxide listed as the active ingredient, this signals a mineral formula
Check for "non-nano" on mineral formulas, meaning the particles are large enough to stay on the skin's surface rather than potentially being absorbed
Broad-spectrum protection means coverage against both UVA and UVB rays, look for this on any sunscreen, mineral or chemical
Water-resistant labeling always has a time limit (40 or 80 minutes), reapply after swimming or heavy sweating regardless of what the bottle says

What About Spray Sunscreens?
Sprays are convenient, especially for wiggly kids or quick reapplication, but they come with two considerations worth knowing. First, inhalation risk means sprays shouldn't be used directly on the face. Second, it's notoriously easy to under-apply with a spray, since it's hard to see or feel how much has actually landed on the skin. If you do use a spray, a thin layer rubbed in by hand afterward helps ensure even, adequate coverage.
Flourish Product of the Month: What We Chose and Why
This is exactly why we chose Babo Botanical Mineral Sunscreen as our July Product of the Month. It's EWG Verified and listed on the EWG Healthy Living app, uses non-nano zinc oxide for broad-spectrum protection, and skips the synthetic fragrances and chemical filters found in so many drugstore options.
It's available through our Fullscript store at 10% off this month, right alongside the supplements we already trust and recommend.
Frequently Asked Questions
What does EWG Verified mean?
EWG Verified means a product meets the Environmental Working Group's strict criteria for ingredient transparency and safety, with no ingredients from their list of chemicals of concern. It's an independent, science-based certification, not just a marketing claim.
Is mineral sunscreen better than chemical sunscreen?
Mineral sunscreen sits on top of the skin rather than absorbing into it, which is why many people, especially for children or daily reapplication, prefer it. Both types can offer broad-spectrum protection, but mineral formulas involve less systemic absorption.
What's the difference between mineral and chemical sunscreen?
Mineral sunscreens use zinc oxide or titanium dioxide to physically reflect UV rays off the skin's surface. Chemical sunscreens use ingredients like oxybenzone or avobenzone that absorb into the skin to filter UV radiation before it causes damage.
How do I know if a sunscreen is actually safe?
Check for EWG Verification or scan the product with the EWG Healthy Living app for an independent safety rating. Look for non-nano zinc oxide or titanium dioxide as the active ingredient if you're seeking a mineral formula.
Is Babo Botanical sunscreen safe for kids?
Yes. Babo Botanical formulas are EWG Verified and use non-nano zinc oxide, which is a common first choice among mineral sunscreens for babies and young children because it isn't absorbed into the skin.
What does reef safe actually mean?
Reef safe generally means a sunscreen avoids oxybenzone and octinoxate, two chemical filters linked to coral reef damage. Mineral sunscreens are naturally reef safe, since they don't use either ingredient.
