Our main sunscreen guide includes a more-detailed explanation of the differences among chemical, physical, and combination sunscreens, as well as information on ingredient safety and effectiveness. Sunscreens that rely on both types of blockers are known as combination sunscreens.
Ingredients that rub in easily and don’t smell: By and large, sunscreens that use a blend of chemical UV filters (which absorb rays, but on their own can be smelly) and physical UV blockers (which act as a shield, but on their own can leave a white cast) are neither too smelly nor too hard to rub in.All of the ones we tried do provide protection against both. Protection against all sun rays: Look for the words “broad spectrum” on the label to confirm that a sunscreen covers the full UV range, providing protection against both UVB and UVA rays.For our research and tests, we excluded sunscreens with an SPF lower than 30, but we didn’t exclude sunscreens with a higher SPF. Higher-SPF formulas can be harder to rub in and can leave more of a white cast, while providing minimal additional protection.

The right amount of SPF: SPF 30 shields skin from 97% of the sun’s UVB rays, and it’s what the American Academy of Dermatology advises as a minimum for daily wear.
