Skin aging and its clinical manifestation is associated with altered molecular metabolism in the extracellular matrix of the dermis. In a pilot open-label study, we investigated the effect of a dietary supplement, BioCell Collagen(®) (BCC), which contains a naturally occurring matrix of hydrolyzed collagen type II and low-molecular-weight hyaluronic acid and chondroitin sulfate, in 26 healthy females who displayed visible signs of natural and photoaging in the face. Daily supplementation with 1 g of BCC for 12 weeks led to a significant reduction of skin dryness/scaling (76%, P = 0.002) and global lines/wrinkles (13.2%, P = 0.028) as measured by visual/tactile score. Additionally, a significant increase in the content of hemoglobin (17.7%, P = 0.018) and collagen (6.3%, P = 0.002) in the skin dermis was observed after 6 weeks of supplementation. At the end of the study, the increase in hemoglobin remained significant (15%, P = 0.008), while the increase in collagen content was maintained, but the difference from baseline was not significant (3.5%, P = 0.134). This study provides preliminary data suggesting that dietary supplementation with BCC elicits several physiological events which can be harnessed to counteract natural photoaging processes to reduce visible aging signs in the human face. A controlled study is necessary to verify these observations.
皮肤老化及其临床表现与真皮细胞外基质中分子代谢的改变有关。在一项开放性标签的初步研究中,我们调查了膳食补充剂 BioCell Collagen(®) (BCC) 的效果,它含有天然存在的水解型 II 型胶原蛋白和低分子量透明质酸及硫酸软骨素基质,参与研究的 26 位健康女性面部均有自然老化和光老化的可见迹象。每日补充 1 克 BCC 持续 12 周,可显著减少皮肤干燥/脱屑(76%,P = 0.002)和整体线条/皱纹(13.2%,P = 0.028),这是通过视觉/触觉评分来衡量的。此外,在补充 6 周后,皮肤真皮中血红蛋白(17.7%,P = 0.018)和胶原蛋白(6.3%,P = 0.002)的含量也显著增加。研究结束时,血红蛋白的增加仍然显著(15%,P = 0.008),而胶原蛋白含量的增加仍在维持,但与基线相比差异无统计学意义(3.5%,P = 0.134)。这项研究提供了初步数据,表明膳食补充 BCC 可以引发多种生理事件,这些事件可以被利用来对抗自然光老化过程,减少人面部的可见老化迹象。需要进行对照研究来验证这些观察结果。
