The short answer

COSRX BHA Blackhead Power Liquid is an exfoliating liquid with willow bark water, betaine salicylate and niacinamide for gentle exfoliation and oil control. At $25 for 100 ml it is worth it if you have clogged pores, blackheads or oily skin and some experience with acids. COSRX suggests it for mid-level acid users.

Our Take

Why it made the edit.

Why we love it: It is a simple, focused formula that goes after clogged pores without a long ingredient list. One bottle lasts because you only use it a few times a week at first.
Skip it if: You are new to acids or have dry, sensitive or over-exfoliated skin.
The catch: Overuse can irritate, so COSRX recommends starting at two to three times a week, and you need sunscreen during the day.
