Low pH Good Morning Gel Cleanser (150 ml)

COSRX's Low pH Good Morning Gel Cleanser is a gel face wash meant for both morning and evening use. The Amazon listing is the 150 ml (5.07 fl oz) tube, sold by COSRX. The listing names tea tree oil and BHA among the ingredients and describes the formula as pH balanced, following skin's slightly acidic natural pH. It is a clear gel that makes a light lather with water: massage a small amount over damp skin, then rinse it off.
