Earth's Recipe Waterful Sun Gel SPF 50+ PA+++ ($25) is perhaps a contender for the world's lightest-weight SPF 50 ever. This Korean brand sunscreen is approved for all skin types, but because it's been formulated with Harrogate sparkling water — which is super high in minerals and silica — it does a superb job of hydrating and plumping the skin without leaving behind any greasy residue. It also contains glycerin to further lock in moisture. And in case you were curious about what the PA+++ means, it's the Korean rating system for protection against UVA rays. PA+++ is the highest rating and P+ is the lowest.
