Supplementation of hydrolyzed collagen to the aging process of the skin: A review


Background: The aging of the skin has emerged as a significant concern, not only among older individuals but also among the younger population, given the increasing trend of longevity. Consequently, there has been a notable rise in the utilization of dietary supplements in recent years. Furthermore, a substantial body of scientific research suggests that the inclusion of hydrolyzed collagen in supplementation can play a significant role in mitigating the visible signs of skin aging. The primary aim of this study is to compile and present a comprehensive summary of the existing evidence pertaining to the effects of hydrolyzed collagen supplementation on human skin.

Methods: This study conducted a narrative review to assess the efficacy of collagen administration in addressing skin aging. The literature search employed the keywords (collagen) AND (skin aging) to identify relevant articles, and the search was conducted on the PubMed database. The included articles' findings were systematically reviewed and presented in a narrative format to provide an overview of the current understanding of collagen supplementation in relation to its impact on skin aging.

Results: We included fourteen articles in this review based on the eligibility criteria. Skin hydration was higher in most of the studies that favored collagen compared to placebo. Ten of 14 articles reported higher skin elasticity following collagen administration. There were six articles assessing skin roughness between both groups and all of them reported lesser skin roughness in the collagen group.

Conclusion: Hydrolyzed collagen can delay and improve the signs of skin aging by improving skin hydration and elasticity, and reducing skin roughness.
