Collagen as a precios dermocosmetic ingredient

Collagen is the most abundant protein in many living organisms and plays an important structural role in determining the mechanical properties and shape of biological tissues. Since its discovery, collagen has been actively researched for cosmetic applications, successfully used in microplastic surgery, as a component of cosmetic products, and as a dietary supplement for anti-aging effects. The increased demand for cosmetics with collagen has generated the need for further studies in this domain. The purpose of this study was to investigate the efficacy and safety of collagen in dermocosmetology and to compare the effectiveness of collagen peptides for oral use and topical use of preparations containing collagen. An analysis of the published studies on the subject was carried out, comparing the effectiveness of using collagen in different ways to improve skin conditions. Part of the investigation was a review of the scientific literature on collagen as a material for improving skin characteristics, the history of the discovery of this protein, its structural characteristics, its chemical composition, its general systemic and topical applications, the sources of collagen, and how it penetrates the skin. The concept of hydrolyzed collagen and its antioxidant properties are considered. The methods of investigating and monitoring the safety of cosmetic preparations are described. It has been concluded that topical collagen, similarly to nutraceutical supplements with collagen peptides, can slow down and reduce the signs of skin aging and can increase skin elasticity, density and moisture in equal measure. No side effects have been reported with the use of the medications. In addition, collagen was a safe component of drugs for local and internal use. Although the harmlessness of collagen is beyond doubt and has been confirmed by studies, the effectiveness of using one type of collagen or another requires further investigation.
