Next, follow with a water-based gel or foaming cleanser, says Dr Phillips, to lift away all traces of oil. Look for ingredients like niacinamide, which helps regulate oil production and soothe inflammation, and salicylic acid, which exfoliates deep inside pores to dissolve buildup and prevent congestion. Ingredients like glycerin and hyaluronic acid are also great, as they help retain moisture and prevent the skin from becoming dehydrated; this can encourage the skin to produce more oil to compensate.
