[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 6

Effect of M-HA 0.32% (w/v), Skinkò E 0.32% (v/v), and permeate (3KDa) Skinkò E on lipid peroxidation after exposure to oxidative stress induced by 50µM H2O2 (a) or UV-A irradiation (b) on HaCaT cells. “∗” in the histogram indicates significant difference at p<0.01, comparing with the Skinkò E and UF Skinkò E Permeate 3kDa treatment groups with respect to M-HA. Data of the amount of lipid peroxides (% respect to CTR) are reported as follows: Graph (a): H2O2=570±14, M-HA=128±7.0, Skinkò E=95.5±7.7, UF Skinkò E Permeate 3kDa=109±4.2. Graph (b): UV-A=480±14.0, M-HA=114±7.0, Skinkò E=74±5.6, UF Skinkò E Permeate 3kDa=76±7.0.
