COSRX BHA Blackhead Power Liquid

COSRX BHA Blackhead Power Liquid is a leave-on exfoliating treatment made for blackheads, clogged pores, excess oil, and rough skin texture.

It uses betaine salicylate, a BHA ingredient, to help clear dead skin buildup and sebum inside the pores. The formula also includes willow bark water and niacinamide, making it suitable for oily and combination skin that needs pore care and smoother-looking texture. Product listings position it for blackheads, dead skin cells, sebum, pore congestion, and oil control.

For Routisca, this should be treated as an exfoliating treatment, not a daily toner. It is best used slowly at night, especially for users who already understand basic skincare.
