Brief Summary
Ultraviolet (UV) irradiation of the skin leads to acute inflammatory reactions such as erythema, sunburn, and chronic reactions, including premature skin aging and skin tumors. UV irradiation is a potent generator of oxidative stress in the skin. Exposure of mammalian skin to UV increases the cellular levels of reactive oxygen species, which damages lipids, proteins, and nucleic acids in both epidermal and dermal cells and contributes to the sunburn reaction as well as photocarcinogenesis and photoaging. In this study, the effects of a topical antioxidant on attenuating the harmful effects of UV irradiation on normal healthy volunteers were studied using biomarkers of skin damage. This study confirms the protective role of a unique mixture of antioxidants on human skin from the harmful effects of UV irradiation. We propose that antioxidant mixture will complement and synergize with sunscreens in providing photoprotection for human skin.

Study Arms (3)
Antioxidant
EXPERIMENTAL30 drops of topical antioxidants (Gluconolactone 4%, Hyaluronic acid 0,01%, Allantoin 0,1%, Ferulic acid 3%, Acetyl heptapeptide 0,001%, Silver vine extract 1%, Ectoine 0,01%, Hydroxyectoine 0,01%, and vehicle) will be applied on tested area on each participant for four consecutive days. On the fifth day, the subject will be irradiated on the tested area. After irradiation, erythema intensity and skin biopsy will be taken. Furthermore, skin tissue will be stained to see sunburn cells and assesses the expression of MMP-9, Thymine Dimer, and p-53 by immunohistochemistry.
Vehicle
PLACEBO COMPARATOR30 drops of topical vehicle (Aqua, Dipropylene glycol, Hydroxypropyl cyclodextrin, Polydextrose, 1,2-hexanediol, Butylene glycol, Propanediol, Caprylhydroxamic acid, Ethylhexylglycerin, Xanthan gum, Benzyl alcohol, Glyceryl caprylate, and Benzoic acid) will be applied on tested area on each participant for four consecutive days. On the fifth day, the subject will be irradiated on the tested area. After irradiation, erythema intensity and skin biopsy will be taken. Furthermore, skin tissue will be stained to see sunburn cells and assesses the expression of MMP-9, Thymine Dimer, and p-53 by immunohistochemistry.
Control
NO INTERVENTIONSkin without intervention and irradiation. Skin biopsy will be taken as a control. Skin tissue will be stained to see sunburn cells and assesses the expression of MMP-9, Thymine Dimer, and p-53 by immunohistochemistry.
