21 Stay A-Thera Peeling Stick

This best-selling spot treatment from Korea contains a powerful formula with AHA and BHA, two chemical exfoliators that prevent acne, whiteheads and blackheads. Its innovative format comes in the form of a cotton bud, so you can exfoliate in specific areas including hard-to-reach areas, like the sides of your nose. Its lactic acid gently dislodges dead skin cells while the glycolic acid exfoliates and smoothes skin texture. A cocktail of tea tree oil and lemon and bamboo extracts provides irritation-free exfoliation. You can use it even if you have hormonal or cystic acne, keeping your skin safe and sound.
