Hello, please ask Vitamin C (L-ascorbic acid) (Ultrafine) can be added to topical lotions. Is it directly on the skin?

Hello Vitamin C type L-ascorbic acid is unstable. When dissolved in water If the formula contains water then Vitamin C can deteriorate quickly. Therefore, it cannot be mixed into the way that the member has informed.
