The Dermalix Shea Butter Brightening Shower Gel 250ml

Avoid mixing AHA/BHA, Vitamin C (Ascorbic Acid) and Niacinamide. Niacinamide is used to treat hyperpigmentation and reduce fine lines and wrinkles, while alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are chemical exfoliants. Niacinamide generally works well with most products, but it's best not to combine it with vitamin C (Ascorbic Acid) in the same routine as it can cause irritation. You can use separately in alternative time.
