Fig. 1. Effect of PPE on skin water-holding capacity (A) and transepidermal water loss (B) in UVB-irradiated hairless mice. NC: Drinking water intake without UVB irradiation; Con: Drinking water intake with UVB irradiation; PO: 0.1% hydrolyzed collagen (HACP-U2) intake in drinking water with UVB irradiation; OL: 0.05% PPE intake in drinking water with UVB irradiation; OH: 0.1% PPE intake in drinking water with UVB. Values are mean±SEM (n=6). Means with different letters indicate significant differences at p<0.05.
