Fig. 4From: Protective effects of galangin against UVB irradiation-induced photo-aging in CCD-986sk human skin fibroblastsEffect of galangin on FGF-2 (a) and type 1 procollagen (b) expression. CCD-986sk human skin fibroblasts were pre-treated by UVB (20 mJ/cm2), then treated with various concentration of galangin for 72 h. The results were expressed as means of triplicates ± standard derivation. *P < 0.05 and **P < 0.01 compared with controlBack to article page
