This study assessed the preventive benefit of a dermocosmetic product, M89PF, containing Vichy mineralising water, probiotic fractions, antioxidant vitamins and hyaluronic acid, in protecting skin physical barrier and defense functions after exposure to UV or O3. The results showed that M89PF significantly prevented the decrease of skin barrier markers' expression levels and inhibited the induction of oxidative stress and inflammatory markers by UV, O3, or both combined.
Purpose: Exposure of the skin to ultraviolet radiation (UV) or ozone (O3) results in stressed skin, leading to the alteration of the skin physical barrier and defence functions. In this work, the preventive benefit of a dermocosmetic, M89PF, containing Vichy mineralising water, probiotic fractions, antioxidant vitamins and hyaluronic acid, in the alteration of skin physical barrier and skin defence functions after exposure to O3 and UV, alone or combined, was assessed. Methods: Untreated and treated (M89PF) skin explants were exposed to O3, to UV rays or to O3+UV. Immunofluorescence was performed for skin barrier, oxidative stress, and inflammatory markers after one and four days of exposure to the pollutants. Results: M89PF significantly (p & LE;0.05) prevented the decrease of the expression level of different skin barrier markers, and significantly (p & LE;0.05) prevented the induction of OxInflammatory markers and inflammasome components by UV, O3, or both combined. Conclusion: M89PF prevents skin barrier damage, as well as oxidative stress and inflammatory markers induced by exposome factors, such as UV, O3, or both combined.
