Stable form of vitamin C combined with glucose.When properly formulated and absorbed into skin, it breaks down to ascorbic acid (pure vitamin C). It functions as an antioxidant and works well with other replenishing and antioxidant ingredients to preserve key substances skin needs to look smoother, brighter, and younger. Research on ascorbyl glucoside’s ability to improve uneven skin tone or spots isn’t too exciting, at least compared with more studied types of vitamin C; however. ascorbyl glucoside plus niacinamide is a viable combination to consider, and several skincare products pair these ingredients. On balance, it’s a good form of vitamin C to consider, though as with any ingredient, skin will reap greater benefits from a mix of great ingredients rather than focusing on just one and hoping it does it all.
