Anti‐skin aging effect of sea buckthorn proanthocyanidins in D‐galactose‐induced aging mice
2024
Overview
Oxidative stress in skin cells caused by changes in the external environment is one of the principal causes of skin aging. Sea buckthorn proanthocyanidins (SBPs) have good free radical scavenging ability. We established a senescence model by injecting 500 mg/kg D‐galactose into the dorsal necks of mice, and then different doses of SBP (25, 50, and 100 mg/kg) were gavaged to explore the effects of SBP on the skin tissues of senescent mice and elucidate the related mechanism of action. The results reveal that SBP can alleviate the skin aging phenomenon caused by D‐galactose‐induced aging. It can also enhance the total antioxidant capacity in the body, thereby strengthening the body's antioxidant defense capability. In addition, SBP can effectively improve skin aging by regulating the TGF‐β1/Smads pathway and MMPs/TIMP system, increasing the relative content of Col I and tropoelastin, further maintaining the stability of collagen fiber and elastic fiber structure. These results will provide the development and production of the antioxidant function of cosmetics and health products, providing a new train of thought. This paper provides an in‐depth analysis of the potential role of sea buckthorn procyanidins in delaying skin aging. The core mechanism lies in reducing oxidative stress in the body, effectively maintaining the relative content of type I collagen and tropoelastin, while maintaining the stability of the skin’s fiber structure. Additionally, sea buckthorn procyanidins can also increase the skin’s moisture content and hyaluronic acid content, further delaying skin aging.
