Hello, these 2 ingredients must be separated and cannot be combined in the same recipe. but can be applied continuously Because the interaction time is slower than Vitamin C type ascorbic acid with Niacinamide very much, in the case of 2 formulas with Niacinamide and Vitamin C type ascorbic acid must leave 15-30 minutes.
