Beauty of Joseon's Green Plum Refreshing Toner : AHA + BHA is a chemical peel based on 2% glycolic acid, 0.5% salicylic acid, 25% green plum water and 2% mung bean extract. Glycolic acid makes the complexion more radiant and even. Like all AHAs, glycolic acid works by helping to remove dead skin cells from the skin's surface. Along with salicylic acid, the scrub helps address a number of key concerns including pigment spots, uneven complexion, blemishes and signs of aging such as fine lines and wrinkles. At the same time, green plum water and mung bean extract have a calming and antioxidant effect.
