Hamamelitannin is primarily recognized for its potent antioxidant properties, making it valuable in skincare and cosmetic formulations. It helps protect the skin from oxidative stress caused by environmental factors like UV radiation and pollution, thereby reducing signs of aging such as wrinkles and fine lines. Additionally, it exhibits anti-inflammatory effects, which are beneficial in soothing irritated or sensitive skin and reducing redness. In hair care products, hamamelitannin is used to strengthen hair follicles and improve scalp health. Its astringent properties also make it useful in toners and cleansers for tightening pores and controlling excess oil production. Furthermore, it has been explored for its potential in wound healing due to its ability to promote tissue repair and reduce inflammation.
