Coffee is a source of nutrients and antioxidants that may benefit the skin, scalp, and hair. A person can use it to exfoliate, treat acne, increase blood flow, and balance pH levels. Applying coffee to the hair can be a great way to help rebalance the pH levels of the hair and scalp. This can also help to scrub away dead skin cells from the scalp. Caffeine stimulates blood flow and widens, or dilates, the blood vessels. This increases blood flow, which can help the skin to naturally tighten.Coffee contains antioxidants, such as polyphenols. These may help to protect against ultraviolet (UV) rays and some signs of aging linked to sun exposure. The antioxidants, stimulants, and chlorogenic acids in coffee may make it an effective acne-fighting facial scrub. Acne occurs when oil, dead skin cells, and other substances clog pores, which can become infected by bacteria, resulting in inflammation. Coffee may be very effective at cleansing the feet and smoothing and softening the skin.
