Natural Mechanisms of Photoprotection

The skin possesses several natural defence mechanisms that help protect it against the harmful effects of ultraviolet (UV) radiation.

1
Production of dark melanin
2
Production of antioxidant enzymes
3
Thickening of the epidermis
4
Repair of damaged molecules
(e.g. DNA)
5
A diet rich in natural antioxidants

The first four mechanisms are largely determined by each individual's genetic background and therefore vary considerably from one person to another.

The fifth mechanism is related to lifestyle and depends on dietary habits. In this respect, the Mediterranean diet is particularly rich in natural antioxidants.
