Pores + blackheads

A water-light BHA exfoliant with 4% betaine salicylate and niacinamide, made on willow bark water.

COSRX’s million-seller works inside pores to clear the oil and dead skin that turn into blackheads. Willow bark water replaces plain water as the base, and niacinamide helps balance oil and fade the marks breakouts leave.

What’s inside

The ingredients doing the work

  • Betaine salicylate

    A milder relative of salicylic acid. It exfoliates the surface and deep inside pores to clear congestion and blackheads, with less irritation.

    No. 3 of 10 on the list

  • Willow bark water

    The base of the formula, in place of plain water. Willow bark is a natural source of BHA that gently helps exfoliate.

    No. 1 of 10 on the list

  • Niacinamide

    Vitamin B3. Helps regulate oil, reduce marks from spots, boost radiance and soothe.

    No. 4 of 10 on the list

  • Panthenol + hyaluronic acid
