The effect of daily ingestion of collagen peptide on the skin damage induced by repeated UV-B irradiation was examined. Ingestion of collagen peptide (0.2 g/kg/d) suppressed UV-B-induced decreases in skin hydration, hyperplasia of the epidermis, and decreases in soluble type I collagen. These results suggest that collagen peptide is beneficial as a dietary supplement to suppress UV-B-induced skin damage and photoaging.
研究了每日摄入胶原蛋白肽对反复紫外线B照射所致皮肤损伤的影响。摄入胶原蛋白肽（0.2克/千克/天）可抑制紫外线B诱导的皮肤水分减少、表皮增生以及可溶性I型胶原蛋白减少。这些结果表明，胶原蛋白肽作为一种膳食补充剂，有助于抑制紫外线B诱导的皮肤损伤和光老化。
