Inhibitory effect of antioxidant peptides derived from Pinctada fucata protein on ultraviolet-induced photoaging in mice

► Pinctada fucata antioxidant peptides slow down formation of wrinkles and skin elasticity induced by acute UVB irradiation. ► The peptides were shown to display the progress of photoaging and repair the injury of photoaging. ► We used firstly smearing peptides in the mouse's back to prove the anti-aging activity of peptides.
