Effect of APCP on the viability (A), COL1A and TGFβ 1 mRNA level (B), and effect of GPH on COL1A and TGFβ1 mRNA level (C) in UVB-irradiated fibroblast cell. Values are expressed as mean±SD. Significant differences: ^#P<0.05 and ^##P<0.01 as compared with normal control; ^*P<0.05 and ^**P< as compared with UV-irradiated control.|@|~(^,^)~|@|Effect of APCP on UVB-induced wrinkle formation. Skin replica image (A) and wrinkle parameters (B) were analyzed by Visioline^® VL 650. Values are expressed as mean±SEM. Significant differences: ^##P<0.01 as compared with normal control group; ^*P<0.05 and ^**P<0.01 as compared with the UV-irradiated control.|@|~(^,^)~|@|Effect of APCP on UVB-induced skin deformation. Skin histological image (bar=200 μm) (A), and epidermal and dermal thickness (B). Values are expressed as mean±SEM. Significant differences: ^##P<0.01 as compared with normal control group; ^*P<0.05 and ^**P<0.01 as compared with the UV-irradiated control.|@|~(^,^)~|@|Effect of APCP on UVB-induced decrease of skin hydration. TEWL (A) and subcutaneous hydration (B). Values are expressed as mean±SEM. Significant differences: ^##P<0.01 as compared with normal control group; ^*P<0.05 as compared with the UV-irradiated control.|@|~(^,^)~|@|Effect of APCP on UVB-induced decrease of skin elasticity. Skin deformation curve obtained with a cutometer (A) and skin elasticity (B). Values are expressed as mean±SEM. Significant differences: ^#P<0.05 and ^##P<0.01 as compared with normal control group; ^*P<0.05 as compared with UV-irradiated control. R2 (Ua/Uf), gross elasticity; The higher the value, the more elastic the curve. R5 (Ur/Ue), net elasticity; The higher the value, the more elastic the skin. R6 (Uv/Ue), portion of the visco-elasticity on the elastic part of the curve; The smaller the value, the higher the distensibility of the elastine fibres. R7 (Ur/Uf), portion of the elasticity compared to the complete curve; The higher the value, the more elastic the skin.
