Korean clay masks help absorb excess oil and lift away surface buildup, making them a useful treatment for oily, combination or congested skin. Formulas with kaolin or bentonite can leave pores looking clearer and skin feeling smoother, although they cannot permanently reduce pore size.

Apply a thin, even layer to clean skin and rinse according to the product’s directions, ideally before the mask becomes completely dry and tight. Follow with a hydrating toner and moisturiser to keep your skin feeling balanced and comfortable.
