Sun products protect the skin against UVA and UVB rays by means of filters and / or screens.
Chemical filters act by absorbing the energy transmitted by luminous radiations. They are not always photostable and as they can be absorbed by the epidermis, there is a risk of phototoxicity and allergy.
Mineral screens reflect and diffuse UV rays. They are inert, photostable and form a film on the skin’s surface which limits any risk of penetration.
Organo-mineral screens absorb and reflect UV rays. They are photostable and have good staying power on the skin’s surface.
