Watch for

Application amount is where most protection is lost; most people apply a quarter to half of the tested dose. 'Mineral' and 'chemical' describe mechanism, not safety rank.

Access

Effective sunscreens exist at drugstore prices; texture, tint, and finish are worth paying for because they drive daily use. Imported Asian sunscreens use filters not yet approved in the U.S.

Forms and strengths

Mineral (zinc oxide, titanium dioxide)
Organic filters (avobenzone, octocrylene, homosalate, octisalate, and now bemotrizinol)
Tinted formulas with iron oxides for visible-light protection

How to use it

Broad-spectrum SPF 30 or higher, about a quarter teaspoon for the face, every morning, reapplied every two hours outdoors. Under makeup, a tinted mineral formula doubles as base.

Side effects and cautions

Stinging near the eyes with some organic filters
White cast from mineral filters on deeper skin tones
Rare allergic contact dermatitis

Get advice first if

Mineral filters are the default for infants over 6 months and reactive skin. Some organic filters are absorbed systemically; FDA has asked for more data, not ordered them off the market.

Regulatory status

OTC drugs regulated under FDA's sunscreen monograph; zinc oxide and titanium dioxide are recognized as safe and effective, and bemotrizinol became the first new U.S. filter in decades in 2026. The E.U., Australia, Japan, and Korea approve more filters, which is why imported sunscreens differ.

In the trends

Sunscreen contouring, 'chemical filters are toxic' posts, and Korean sunscreen imports are all in the trends desk.
