Sunscreen Ingredients

RELATED CONTENT

And be aware that all sunscreens are not created equal. Some sunscreen ingredients can cause skin irritation, while others could disrupt your body's endocrine systems. The U.S. Food and Drug Administration (FDA) regulates some sunscreen products as drugs, and some as cosmetics, which have less stringent approval requirements. While the FDA created a monograph for safer sunscreens in 1999, the guidelines were never finalized.

Many environmental groups have expressed concern that certain sunscreens contain 'micronized' ingredients, or nanoparticles, such as titanium dioxide and zinc oxide that are manipulated to smaller particle sizes. Some research on micronized titanium dioxide indicates that it may cause more DNA damage than larger titanium dioxide particles, particularly if it enters the body through cuts or inhalation. Because nanoparticles operate on the quantum level, their behavior and absorption by the body may differ from larger particles of the same substance because they're so small. To be safe, avoid products with micronized ingredients and never apply sunscreen to cuts.

To find out which products contain the safest ingredients and provide the best sun protection, check out these useful resources:
