Catechins, a type of flavonoid, are known for their antioxidant and antibacterial properties. Recent research highlights their potential in cosmeceuticals, particularly in preventing aging, inhibiting hyperpigmentation, and protecting against UV radiation and inflammation. Catechins are now used in cosmetics, with formulations containing them as active ingredients in products like soaps, sunscreens, and creams. This review discusses the antioxidant potential of catechins in cosmetic formulations and the current status of clinical trials in cosmetics. Catechins, found in tea, fruits, and plants, have shown significant antioxidant activity, which helps in reducing oxidative stress, preventing skin aging, and inhibiting melanin production. They also exhibit anti-inflammatory and anti-acne properties. The physicochemical properties of catechins, including their structure and stability, influence their effectiveness in cosmetic applications. Various studies have demonstrated the antioxidant, anti-aging, skin brightening, and UV-protective effects of catechins. Catechins are incorporated into different cosmetic formulations, such as lip balms, shampoos, and sunscreens, and are also used in liposomal and transferosome forms to enhance skin absorption. Clinical trials are ongoing to evaluate the safety and efficacy of catechins in cosmetics. Overall, catechins show promise as multifunctional ingredients in cosmeceuticals due to their antioxidant, anti-aging, and skin-protective properties.Catechins, a type of flavonoid, are known for their antioxidant and antibacterial properties.
