Differin Daily Oil-Free Hydrating Cleanser is a daily cleanser designed specifically for oily to combo skin. Its oil-free formula features 5% polyhydroxy acids (PHAs) as one of the key ingredients, which help to rebalance the skin to gently soften and hydrate. Plus, it contains a unique amino-acid based cleansing system that quickly breaks down and dissolves surface oil and pore-clogging impurities without leaving skin feeling tight or dry.
