How it works
A BHA is the oil-soluble acid, which is why it is the one reached for when the complaint sits inside the pore rather than on the surface. This is the BHA liquid in COSRX's line, thin enough to go on with a cotton pad after cleansing, in place of the toner step. Skin with blackheads across the nose and chin is the case it fits, and a scrub on that skin usually leaves it tight without clearing anything. Two or three evenings a week is a sensible ceiling, with moisturizer after it the same evening. Sunscreen the next morning is part of using an acid at all.
Key benefits
- Willow bark water, not plain water, is the first ingredient
- Betaine salicylate sits third for gentle oil and blackhead care
- Niacinamide follows for a more even, refined look
- Panthenol and sodium hyaluronate cushion the exfoliation
COSRX BHA Blackhead Power Liquid
What is the BHA Blackhead Power Liquid actually for?
This is a liquid toner built on willow bark water as its base rather than plain water, with betaine salicylate third on the list as the BHA-style ingredient that does the work around congested, blackhead-prone pores. Niacinamide follows in fourth position, and panthenol and sodium hyaluronate sit further down to keep the formula from feeling stripping. It reads as a targeted pore-and-texture liquid rather than a general hydrating toner.
Is this liquid suitable for sensitive or reactive skin?
There is no added fragrance, essential oil, denatured alcohol, or silicone anywhere on the ingredient list, and no sulfate surfactants either, which removes several common irritant triggers. That said, betaine salicylate is still an exfoliating ingredient sitting near the top of the formula, so anyone new to BHA liquids should patch test and introduce it slowly rather than assuming mild means inert. Sensitive skin can often tolerate it, but that is a decision to make with a patch test, not a label claim.
How long before I notice a difference in my pores?
Betaine salicylate works through repeated use, not a single application, since exfoliation of this kind builds gradually as dead cell buildup around pores is cleared over successive uses. Expect the visible change in texture and pore appearance to show up over several weeks of consistent use rather than overnight. Skipping days here and there simply slows the timeline rather than breaking it.
Can I layer this with a brightening serum or other actives?
Niacinamide is already built into this liquid at the fourth position, so a separate niacinamide step mostly repeats what's already here rather than adding something new. No brightening acid or retinoid sits on this ingredient list, so pairing with either is a decision about your other products, not this one, and starting a new exfoliating acid on the same night as this liquid is worth easing into slowly. Sodium hyaluronate and panthenol further down the list are there to keep the base comfortable however you build around it.
How do I confirm my bottle is the authentic Korean-market formula?
COSRX runs its own verification rather than asking customers to trust a reseller: the batch number and expiration date printed directly on your unit go into a checker on cosrx.com. Read those two details off the physical package itself, not from any listing text, since that independence is the point of the system. This bottle carries EAN 8809416470054, the Korean-market barcode intact and unswapped.

How to use
- Use the BHA Blackhead Power Liquid in the evening, after cleansing, in place of your toner step.
- Sweep it over dry skin with a cotton pad, over the nose and chin first, keeping clear of the eye area.
- Wait a minute, then follow with a hydrating layer and moisturizer the same evening.
- Start at two evenings a week and build from there. Do not use it in the same routine as another acid or a retinoid.
