Can I use SkinCeuticals Topical Vitamin-C products with alpha and beta hydroxy acids, retinoids (including Retin A and Renova) and other popular skin care products?
Generally, yes, although it is recommended that you consult your doctor or skin care professional to be certain. SkinCeuticals Topical Vitamin-C products should not be used at the same time of day as these other products. The recommended regimen is an application of SkinCeuticals Topical Vitamin-C products in the morning and use of other acid or retinoid based products at night.
