Abstract
Skin photoprotection has become a real public health issue in view of the consequences of the sun on unprotected skin such as erythema, immunosuppression, skin cancer. The major role of UVA rays has long been neglected, even though their harmful effect over the long term, by notably generating oxidative stress. To prevent it, it has become important to provide biological protection in addition to sun filters. The aim of this study was to demonstrate the in vitro complementary efficacy of an active complex with sun filters on intracellular oxidative stress in normal human epidermal keratinocytes (NHEK) irradiated with the full solar spectrum (FSS).
