Chemical vs. physical sunscreens
Some people find their skin doesn’t tolerate chemical sunscreens but it’s worth noting that they are not bad for the skin. Chemical and physical SPF’s just work in different ways. A chemical sunscreen works by converting and scattering UV radiation into heat. This doesn’t cause a problem for many skins but people with sensitive skin may have an issue with this. Physical sunscreens work by creating a barrier that prevents UV rays from hitting the skin at all. Physical sunscreens are better for sensitive skin but traditionally can be hard to blend, leaving a white cast on the skin.
