5 Mineral Sunscreen Myths, Debunked

There’s been a lot of talk about mineral sunscreen lately, including how it works, what it looks like, and whether it’s “better” than chemical sunscreen. And with so much chatter, it can be tricky to separate fact from fiction. As the Experts in SPF™, we’re stepping in to clear things up.

Below, we’re breaking down some of the biggest myths about mineral sunscreen and giving you the sheer truth about what makes it unique.

1. “Mineral SPF is Always Thick, White, and Pasty”

Busted: This may have been true years ago, but not anymore. Early mineral sunscreens often left a heavy, chalky finish that made them tough to love. But thanks to science and smarter formulations, today’s mineral SPFs can be just as feel-good as other options.

Take our Mineral Unseen Sunscreen SPF 40. This weightless, cloud-like lotion glides smoothly onto skin and softly blends in sheer for a dream-like feel. Oh, and did we mention it doubles as a makeup-gripping primer?

“It goes on like liquid suede,” says customer Tina C. “It feels light as a feather, makes my foundation go on much more smoothly, and I feel good knowing that it’s also protecting my skin from the sun at the same time.”

2. “Mineral Sunscreen Can Be Invisible”

Busted: Nope! This one is pure marketing. While mineral formulas have come a long way, they can never be 100% invisible. That’s because they’re made with mineral actives like zinc oxide and titanium dioxide, which are white powders that sit on top of your skin and work as a physical shield to block UV rays.

What they can be is lightweight and blendable enough to help minimize white cast. If you’re looking for sheer formulas that glide onto skin with ease, check out our guide to mineral sunscreens that minimize white cast. You’ll see how the right mineral SPF can strike the perfect balance between expert protection and wearable elegance.

3. “All Mineral SPF Is Good and All Chemical SPF Is Bad”

Busted: This is an important one. A “good” sunscreen isn’t defined by whether it’s mineral or chemical. It’s defined by whether it effectively protects your skin and works for you. That’s why we recommend sunscreens with broad spectrum protection (e.g. they protect against both UVA and UVB rays), an SPF of 30 or higher, and that fit into your lifestyle in a way that makes you want to use it every day.

Mineral sunscreen might be a great choice for you if you have sensitive skin. Chemical SPF, on the other hand, may be a better pick if you want something that’s 100% invisible. Neither one is inherently “better” or “worse.” The best SPF is the one you’ll actually wear.

4. “Mineral Sunscreen Is Natural, So That’s Why It’s Better”

Busted: No sunscreen is completely “natural.” Both mineral and chemical SPF actives are created in a lab, and that’s intentional. It ensures they’re safe, stable, and effective at protecting your skin.

What matters most is that all SPF actives are tested and regulated to ensure they do their job: keeping your skin safe from UV rays.

5. “Mineral Sunscreen Is More Effective”

Busted: When formulated correctly, mineral and chemical sunscreens can be equally effective at protecting your skin.

This means that SPF 40 is SPF 40, regardless of whether the formula uses mineral or chemical filters. (On that note, check out our ultimate guide to SPF levels.)

What you may notice are differences in texture, finish, and how the sunscreen feels on your skin. That’s why finding the right SPF is more about what feels right for you.

Don’t Let Myths Keep You from Your SPF Match

When it comes to mineral vs. chemical SPF, there’s no “winner.” Both are highly effective when formulated used correctly, and both can offer the broad spectrum protection your skin needs. What really matters is finding the formula you’ll reach for every single day. Maybe that’s a sheer mineral option that feels light and airy on sensitive skin. Or maybe it’s an invisible sunscreen that disappears completely on any skin tone.

Myths shouldn’t stand between you and the protection your skin deserves. At Supergoop!, there’s an SPF that fits seamlessly into your routine, whether that's chemical or mineral.
