It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
