A lightweight exfoliating liquid formulated with BHA (betaine salicylate) and niacinamide to help clear clogged pores, reduce blackheads, and refine skin texture — ideal for oily, combination, and blemish-prone skin. 

Description:

COSRX BHA Blackhead Power Liquid (50 ml) is a chemical exfoliant designed to gently dissolve dead skin cells and excess oil deep within pores, helping to reduce blackheads and improve overall skin clarity. Its lowirritation, lowpH formula features 4% betaine salicylate (a gentle BHA) and willow bark water, which works to refine skin texture and clear congested areas like the Tzone, nose, and chin. The addition of niacinamide helps improve skin tone and minimize the appearance of pores, while hydrating actives like panthenol and sodium hyaluronate support moisture balance.

How to use:

1. After cleansing and toning, apply a small amount directly to areas prone to blackheads and clogged pores or use a cotton pad.
2. Gently pat or glide the liquid over the face, avoiding the eye and lip areas. Use 2–3 times per week at first; increase gradually depending on your skin’s tolerance.
3. Follow with hydrating serum and moisturizer.
4. Always apply sunscreen during the day, as BHA increases sun sensitivity.
5. Important: Avoid combining with other strong acids, retinoids, or high-strength Vitamin C on the same night to prevent irritation.
