How to Choose a Mineral Sunscreen That Works

A sunscreen only works if you wear it, so texture and finish matter as much as the label. Mineral sunscreens are the ones built on zinc oxide and titanium dioxide. Here is what the FDA and the American Academy of Dermatology say about choosing one.

What “mineral” means

Mineral sunscreens use zinc oxide, titanium dioxide, or both as their active ingredients. In a 2021 proposed order, the FDA proposed that sunscreens with these two ingredients, at concentrations up to 25%, are generally recognized as safe and effective, saying the public record holds sufficient safety data. For 12 other sunscreen ingredients, including oxybenzone and avobenzone, the FDA said it needs more data before it can make that call.^[1] That is a request for data, not a ruling that those ingredients are unsafe, and the proposal has not been finalized for these ingredients (in 2026 FDA did finalize two related orders: adding bemotrizinol as a new active ingredient on June 10, and removing PABA and trolamine salicylate on September 10).^[1]

Who might prefer mineral

The American Academy of Dermatology (AAD) suggests a sunscreen with only zinc oxide and titanium dioxide for people with rosacea and for skin that stings or burns when sunscreen goes on. For sensitive skin, it advises choosing a product labeled for sensitive skin and avoiding fragrance, parabens, and oxybenzone.^[2]

Dealing with white cast

Mineral formulas can leave a white residue. The AAD says a tinted sunscreen that matches your skin tone can help avoid it, and that tinted products also help protect against visible light, which can worsen dark spots. It adds that a tinted sunscreen should still offer SPF 30 or higher, broad-spectrum protection, and water resistance.^[2]

What to look for when you are shopping

• Broad Spectrum and SPF 30 or higher. The AAD names SPF 30 or higher, broad-spectrum protection, and water resistance as the three essentials.^[2] The FDA says only Broad Spectrum sunscreens with SPF 15 or higher can claim to reduce the risk of skin cancer and early skin aging, when used with other sun protection measures.^[3]
• Water resistance if you sweat or swim. A water resistant label must state 40 or 80 minutes. No sunscreen is waterproof, because all of them eventually wash off.^[3]
• A tint if you want to avoid a white cast.^[2]
• “Moisturizing” or “dry skin” on the label if your skin runs dry, and fragrance-free if it is sensitive.^[2]

Use it well

The FDA advises reapplying sunscreen at least every 2 hours, even if the label says water resistant, and more often after swimming or sweating. It also recommends pairing sunscreen with limited time in the sun and clothing that covers exposed skin.^[3]

The takeaway

Mineral sunscreen is a category with a range of textures and tints. Check the label for Broad Spectrum, SPF 30 or higher, and water resistance, then test a couple of formulas to find one you will put on every morning. If sunscreen makes your skin sting or burn, or you have rosacea, ask a dermatologist which product fits. For babies younger than 6 months, the AAD recommends keeping them in the shade as much as possible and dressing them in lightweight long sleeves, pants, a wide-brim hat, and sunglasses.
