This Pyunkang Yul Acne Toner utilizes BHA (Beta Hydroxy Acid) technology to effectively target and treat areas prone to pimples and blackheads. Formulated to clarify the complexion, this astringent assists in gently exfoliating the skin's surface and penetrating pores to remove impurities. Regular use supports clearer skin by managing breakouts and minimizing the appearance of blemishes, leading to a more refined texture.
