The Environmental Working Group (EWG) states that the FDA has failed to generate any sunscreen safety standards. Many makeup products, particularly foundation and lip balms, contain chemical sunscreens. According to the EWG, however, the evidence that chemical sunscreen protects you from skin cancer is minimal, at best, and some evidence even shows that chemical sunscreen may increase the risk of developing melanoma, a deadly form of skin cancer. Likewise, sunscreen blocks vitamin D absorption, and many chemical sunscreens contain potential hormone disruptors that can be absorbed through the skin.
It’s understandable that you want your cosmetics to smell nice. Unfortunately, many fragrances are chemically generated and can contain multiple chemical compounds. According to The Campaign for Safe Cosmetics, fragrance is considered a “trade secret,” so there’s no way of knowing just what those chemicals are. Instead, you’ll typically find these trade secret scents listed in the ingredients merely as “fragrance.”
Possible problems with the chemicals used to create fragrance include allergic reactions, hormone disruption from phthalates and synthetic musks, and even neurotoxic effects from certain chemicals.
