Physical filters contain microparticles that act as small mirrors that reflect solar radiation, preventing it from being absorbed by the skin.


When making a screen on the skin, this type of filter is not absorbed, and that is why its use is usually recommended for babies. Allergic, reactive or dermatitis skins must also be protected with this type of filter when exposed to the sun’s rays. Therefore, people with a higher risk, whether due to sensitive, light or burn-prone skin, it is advisable to use physical filters.
