Nanotechnology and Photoprotection from Within Out

Excessive exposure to ultraviolet radiation (UV) leads to Development of various skin disorders, such as erythema and hyperpigmentation. Both UVA and UVB rays induce adverse biological effects, including DNA damage, oxidative stress, free radical production, photoaging and skin cancer [1]. Moreover, infrared radiation (IRA) contributes to photoaging by upregulating MMP1 expression in dermal fibroblast [2]. To obtain a more stable and broader photoprotective activity it seems necessary to combine topical and endogenous photoprotection by the combined use of sunscreen emulsions and specific nutraceuticals [3]
