CHEMICAL SPF / SUNSCREENS
What CHEMICAL SPF/SUNSCREENS are
Chemical SPFs include Benzophenone, Oxybenzone, Octinoxate, Octocrylene, Avobenzone, and Homosalate. They work by changing UV rays into heat through a chemical reaction, then release that heat from the skin. Clean SPFs like Zinc Oxide and Titanium Dioxide create a physical barrier layer on the skin to block UV rays.
WHERE YOU CAN FIND THEM + WHY MADEWITH DOESN’T ALLOW THEM
These chemicals can be found in everything from moisturizers, sprays, creams, foundations, tinted moisturizers, liquid bronzers, shampoo, nail polish, lip products, and more. They are linked to hormonal disruption + often an acne trigger. Chemical SPF also has diminishing efficacy over time.
WHERE THEY’RE BANNED OR RESTRICTED
Chemical Sunscreens are banned in the Florida island of Key West, the US state of Hawaii, the US Virgin Islands, The Caribbean island of Bonaire, the archipelago nation of Palau, as well as The Mexican Nature Reserves Xel Ha, Xcaret Park, and Garrafon Natural Reef Park due to their toxicity and damaging effects on reef health.
