Some sunscreens contain chemicals that can be harmful when they wash off in rivers and oceans and have been reported as agents in coral bleaching and can be absorbed by fish. The sunscreens on our list are chemical-free, protect against both UVA (skin cancer-causing) and UVB (sunburn) rays and are all under $25. They are designed to screen those of us that spend all day in the sun, and are extra creamy because of all the zinc, which replaces nasty ingredients. Even if you are impervious to sunburn (congrats!) your skin still absorbs UVA rays, so this applies to you too!

No matter what kind of sunscreen you buy, the Skin Cancer Foundation and the Sierra Club ask you to remember these basics when picking your product:
• Look for sunscreen that has at least SPF 15 and at most SPF 50
• Reapply every two hours and after swimming or heavy sweating
• Make sure it offers ‘Broad Spectrum’ protection, which shields against UVA and UVB rays
• Choose lotions over spray for more consistent coverage
