This amazing serum contains 4% natural BHAs to reduce the formation of blackheads and remove excess sebum that causes blackheads. It contains no water! Instead it uses white willow water, a natural BHA to brighten the skin. Cosrx is the best Korean skincare for acne and oily skin.
After morning or evening facial wash, in the toner and essence stage spread a coin-sized amount lightly on parts with much dead skin cell or blackheads.
Spread thinly on the whole face for smooth skin texture.
Avoid under eye area and use sunscreen as well in daylight.
