    目的 探讨口服海洋鱼皮胶原肽对人体皮肤水份和面部黄褐斑的影响。 方法 选择年龄在30~65岁、皮肤水份≤12者100名和年龄在18~65岁、面部有黄褐斑者100名,分别随机分为试验组和对照组(各50名),进行改善皮肤水份试验、祛黄褐斑试验。受试者每天摄入海洋鱼皮胶原肽2.7 g,连续30 d。在试验前后分别测定皮肤水份、面部黄褐斑的面积和颜色,调查受试者疲劳感、烦躁、睡眠、干涩等不适症状的变化,测定血常规、大小便常规和血液生化指标。 结果 皮肤干燥者口服海洋鱼皮胶原肽后,皮肤水份由(7.48 ± 2.39)增加至(8.68 ± 3.15),得到明显改善(P<0.05),与对照组相比差异具有统计学意义(P<0.01);而对皮肤的油份和pH值没有影响(P>0.05)。面部有黄褐斑者口服海洋鱼皮胶原肽后,黄褐斑的色卡值平均降低(0.35 ± 0.38)度,黄褐斑的面积平均缩小(4.70 ± 8.01) cm2。与试验前比较,两项指标均有明显变化(P<0.01);与对照组相比,两项指标差异有统计学意义(P<0.05)。两组试验中,受试者疲劳感、烦躁、睡眠、干涩等不适症状均有明显改善;血常规、大小便常规和血液生化检查结果均无明显异常,亦未见过敏反应。 结论 口服海洋鱼皮胶原肽能够改善皮肤水份和祛面部黄褐斑,并有助于改善疲劳感、烦躁、睡眠、干涩等不适症状。
