How to Choose the Right Sunscreen for Your Skin Type

With summer UV indexes climbing into dangerous territory across much of the country, protecting your skin has never mattered more. But standing in front of a wall of sunscreen options at the pharmacy can make a simple purchase feel overwhelming. SPF numbers, chemical versus mineral labels, reef-safe claims, sport formulas: here is what you actually need to know before you buy.

Mineral vs. Chemical: What the Labels Really Mean

Sunscreens work in one of two ways. Mineral sunscreens, which use zinc oxide or titanium dioxide as active ingredients, sit on top of the skin and physically reflect UV rays away from the surface. They begin working immediately upon application and are generally better tolerated by people with sensitive skin, rosacea, or melasma. The tradeoff is a noticeable white cast and a heavier feel on the skin.

Chemical sunscreens absorb into the top layer of skin and convert UV radiation into heat, which is then released by the body. They tend to be lighter and more invisible after application, making them popular for everyday use under makeup. Many chemical formulas are also designed to be sweat- and water-resistant for longer periods, which makes them well-suited for outdoor activity.
