The protective effect of a novel sunscreen against blue light.

Background And Objective: Premature skin ageing, and skin hyperpigmentation are influenced by exogenous factors, such as ultraviolet radiation and blue light. In this study, we assess the protective effect of a sunscreen (TDF Blu Voile Sunscreen) in protecting the skin against the harmful effects of blue light irradiation in vivo and through the in situ quantitative and qualitative evaluation of protein carbonylation in human skin explants.

Methodology: The protective effect of the test product against blue light was first evaluated ex vivo on human skin explants.

A novel method for evaluating the effect of pollution on the human skin under controlled conditions.

Background: Generally considered as a major risk factor for various respiratory diseases, air pollution can also have a significant impact on the skin. To date, there is a plethora of cosmetics products with "anti-pollution" claims. However, these claims have not been fully substantiated with robust scientific evidence and currently there is no standardized method in place for validating the anti-pollution efficacy of cosmetics products.
