COSRX BHA Blackhead Power Liquid was the brand's very first product, created after its founder struggled to find a BHA exfoliant that didn't leave sensitive skin red and irritated. Over a decade later, the formula remains almost unchanged, a sign that the original approach still works.
A Gentler Take on BHA
Instead of standard salicylic acid, this formula uses Betaine Salicylate combined with a willow bark water base. This dual-source approach exfoliates inside pores to clear blackheads and prevent breakouts, while typically feeling gentler than stronger BHA products.
A Deliberately Simple Formula
With very few ingredients, there's very little in this bottle that isn't doing real work. Niacinamide adds brightening support, while Panthenol and Hyaluronic Acid help keep skin comfortable and hydrated during exfoliation.

Fitting This Into Your Routine
Apply a thin layer after cleansing with hands or a cotton pad, wait 20-30 minutes before other products, and avoid combining with other acids, retinoids, or Vitamin C the same night.
