A light, oil-free moisturiser to help regulate sebum and reduce red/ brown marks overnight. New TRIPLE size 100ml bottle. Why use a gel moisturiser? For oily/acne prone skin, you want to use a non-comedogenic moisturiser (doesn’t clog pores). For this you ideally want a non-fatty moisturiser (oil free), so a light gel-based moisturiser is preferrable, where you know the water content is high & fat content negligible.
