While all Mad Hippie products are non-comedogenic, our serums are a must for acne-prone skin, particularly the Vitamin C Serum, which can be used morning and night (if not using any other serum). The Vitamin A Serum or AHA Exfoliating Peel can be added at night, starting these serums every other night until skin adjusts (the Vitamin A Serum, in particular, can have a brief adjustment period). The Triple C Night Cream is not recommended for acne-prone skin.
