You put on sunscreen because it is important for your skin’s health, right? In this day and age of skin cancer, most of us have been taught to wear sunscreen daily, especially on our faces, in all weather and all seasons. Lately, however, some concerns have been raised regarding the safety of the sunscreen itself. Just what’s in that sunscreen, and is it safe?
For years we have been told that exposure to ultraviolet rays from the sun can cause skin cancer. Ironically, though, moderate sun exposure may actually prevent the development of certain types of cancer, and the chemicals in sunscreens may increase your risk of skin cancer.
One of the concerns is that certain chemicals in sunscreens produce free radicals, and the formation of free radicals is strongly implicated in cancer. Free radicals cause cellular damage, and cancer is, essentially, the proliferation of damaged cells.
