[Retracted] Positive Effects against UV-A Induced Damage and Oxidative Stress on an In Vitro Cell Model Using a Hyaluronic Acid Based Formulation Containing Amino Acids, Vitamins, and Minerals

Figure 3

Antioxidant biomarkers (SOD-2 and HO-1) were determined by quantitative real-time PCR on HaCaT UV-A pretreated for 4 minutes and subsequently treated with M-HA 0.32% (w/v) and Skinkò E 0.32% (v/v) for 4 hours. Each column represents the mean and error bars represent the standard deviation (n=3). Test-t was performed to evaluate the significance of M-HA and Skinkò E effects with respect to positive control (UV-A), p<0.01.
