"Mature skin not only benefits from hydrating ingredients but also anti-aging ingredients," says NYC-based cosmetic dermatologist Sejal Shah. For a sunscreen that incorporates both hydrating and anti-aging elements, Shah recommends La Roche-Posay Anthelios AOX Daily SPF 50 Sunscreen, $42.50, which provides SPF 50 protection and helps fade away the appearance of fine lines and dark spots.

"Physical sunscreens are best for people with acne-prone skin," board-certified dermatologist Dr. Dendy Engelman says. Engelman says this skin type should look for oil-free, gel textures with titanium dioxide and zinc oxide that won't clog pores. She says SkinCeuticals Physical Matte UV Defense SPF 50, $34, will successfully mattify the skin without leaving a white or chalky residue after application.
