Studies have suggested that the UVs components of the solar spectrum induce photo-oxidation of skin surface lipids, squalene and cholesterol, resulting in their degradation. In addition, UVs lead to oxidative stress.

If sunscreens protect against UV radiations, several studies point now the deleterious impact of infra-red (IR) and the fact that an IR protection should also be added to the products [1-3].

Today, it is well known that UV radiation is responsible of various harmful responses at the cutaneous level. UV rays generate reactive oxygen species and are a source of oxidative stress.
