Layering Daily Acid Toner with Niacinamide

Q.) How Should I Layer the Daily Acid Toner with a Niacinamide Product?

A.) You can use the Daily Acid Toner and a product that contains niacinamide in the same routine. However, please recognize that the Daily Acid Toner's formulated pH of 3.5 - 3.7 may not be synergistic with that of a niacinamide product, which tend to have a higher pH. If you would like to use both products at the same time, use the toner first, wait 30 minutes, then apply the niacinamide. Alternatively, use one product in the morning and the other in the evening.
