This article discusses the potential use of catechins in cosmeceuticals, focusing on their antioxidant and skin care properties. Catechins, a type of flavonoid, are known for their ability to combat oxidative stress and prevent skin aging. They are found in various natural sources, including tea leaves, red wine, and fruits. Recent research highlights their role in inhibiting hyperpigmentation, reducing inflammation, and providing UV protection. Catechins are now being incorporated into cosmetic formulations such as soaps, sunscreens, and creams due to their beneficial effects on skin health. The article reviews the antioxidant potential of catechins and the current status of clinical trials in cosmetics. It also explores the physicochemical properties of catechins, their antioxidant mechanisms, and their applications in anti-aging, skin brightening, and sun protection. Additionally, the article discusses the development of catechin-based formulations in cosmetics, including the use of liposomal delivery systems to enhance stability and absorption. Clinical trials are mentioned, showing the potential of catechins in skincare, although further research is needed. The conclusion emphasizes the importance of catechins in cosmeceuticals for their multifunctional benefits in improving skin health and appearance.This article discusses the potential use of catechins in cosmeceuticals, focusing on their antioxidant and skin care properties.
