What is the difference between a chemical filter and a mineral screen?
Chemical or organic filters, of synthetic origin, have to penetrate the epidermis in order to be active. They protect against UV rays by absorbing them. These filters only become active 20 to 30 minutes after application. They are also suspected of being able to modify the hormonal balance of man and pollute the environment (e.g. they participate in coral bleaching).
On the other hand, mineral screens, of totally natural origin, form a protective barrier on the surface of the skin that reflects UV rays like a mirror.
Mineral screens are immediately active, as soon as they are applied.
In organic certification, only mineral screens, namely titanium dioxide and zinc oxide, are permitted.
In addition to their effectiveness against UVB and UVA rays, mineral sunscreens guarantee optimal tolerance and respect for the skin and the environment.
