L-Ascorbic acid powder also known as Vitamin C. A water soluble natural antioxidant that promotes healthy skin. It promotes collagen and skin regeneration. Taken internally it can not reach the layers of the skin as it does when applied externally to skin. Vitamin C deters dry skin and wrinkles and gives skin a healthy glow. It is not stable in the presence of water and starts to degrade once in contact with water. It can be added to an oil or body butter it gives a grainy feel but will not degrade. In water it disolves but then becomes unstable turning an orange and than brown within weeks so it is best made in small amounts that will be used up within 30 days if adding to creams or lotions or add the powder to the lotion with each application for a healthy glow. Keep tightly sealed in between uses.
