| Résumé : |
Nowadays, vitamin E acetate is used as an antioxidant and moisturizer in sunscreens. Although free vitamin E presents UV protection effects, of vitamin E acetate on cutaneous photodamage, when combined with sunscreens. The aim of this study was to evaluate the protective effect of a sunscreen formulation with or without vitamin E acetate on erythema in hairless mice, transepidermal water loss (TEWL) and sunburn cell formation. The dorsal skin of mice was treated topically with sunscreen formulation with or without 5% vitamin E acetate in two different areas, 15 minutes before UVA/B irradiation. The addition of vitamin E acetate did not protect hairless mousse skin against erythema formation and TEWL. However, it protected the skin against sunburn cell formation. Consequently, vitamin E acetate can enhance the protective effects of sunscreens against sunburn cell formation, which can only be seen by traditional histopathological analysis, but will go unnoticed by non-invasive methodologies. |
