Filtro físico ou químico, qual o melhor?

Chemical Sunscreen Sunscreen - or chemical protector - is one of the most common versions among those looking to protect themselves from the sun. In practice, it works by creating a chemical barrier on the surface of the skin (hence the name), preventing radiation from actually entering the skin. How it works: in general, the filter contains organic active ingredients in its composition, and they are responsible for absorbing UV rays. In general terms, it is as if this product were a sponge, sucking up each one of them to prevent the breakdown of collagen molecules and the production of free radicals in the skin. Who is it most suitable for? Anyone who does not have restrictions or skin problems. Physical Sunscreen Although it has the same function as chemical protector, the physical type of product acts differently when in contact with the skin. Also known as sun block, these cosmetics work by reflecting the sun's rays instead of reacting with them. How it works: made of minerals, sunscreens are not absorbed by the skin like sunscreens - and therefore maintain a whitish appearance for the entire time after being applied to the body and face. So, when UVA and UVB rays hit the area protected by the physical filter, zinc oxide and/or titanium dioxide reflect the rays and prevent them from entering the skin cells. Who is it most suitable for? People who are undergoing dermatological treatment, those with allergies or skin sensitivity, as well as pregnant women and children.
