Product details

A bottle of COSRX AHA 7 Whitehead Power Liquid on a white table between a pink apple with a slice and a glass sphere

Whiteheads + texture

A water-light AHA exfoliant with 7% glycolic acid and niacinamide, made on apple fruit water.

COSRX’s AHA 7 sweeps away the dead skin cells that build up into rough patches and tiny white bumps, for smoother, more radiant skin. Apple fruit water replaces plain water as the base, niacinamide helps fade marks and balance oil, and the formula is kept at a mildly acidic pH so it works without needless irritation.

Good to know

  • Contains an AHA, which can make skin more sensitive to the sun. Wear sunscreen during the day.
  • Start once a week and build up to 2–3 times a week. Sensitive skin may feel some irritation at first; COSRX suggests easing it in gradually.
  • Avoid layering it with other acids, retinols or vitamin C, and COSRX advises avoiding AHAs and BHAs when pregnant or breastfeeding.
  • Free of gluten, palm oil, silicones, parabens, ethanol and artificial fragrance, per COSRX. Comes in 100 mL.
