When deciding to buy your next sunscreen lotion, you have 3 choices. An Organic Sunscreen, a Chemical Block Sunscreen or a Physical Block Sunscreen. Each have their own effective way to filter out the sun’s harmful UV radiation.
Let’s start off by looking at how a chemical sunscreen works.
Chemical sunscreen work by absorbing ultraviolet rays before they reach the skin’s surface by converting it from light to heat energy. Chemicals such as benzophonones, oxybenzone and cinnamates are used as such UV absorbing ingredients. However, there is a real question mark on the safety of it’s use as research have shown that the use of chemical sunscreen is linked to the higher incidence of skin cancer due to its free radical generating and DNA/hormone discrupting properties.
