COSRX BHA Blackhead Power Liquid is a leave-on exfoliating liquid with 4% betaine salicylate, a gentle BHA, in a willow bark water base. It loosens the oil and dead skin that clog pores, so blackheads, rough texture and congested-looking pores look clearer over time. It suits oily, combination and acne-prone skin. The COSRX BHA blackhead power liquid we sell is the original from COSRX in 100ml, shipped from Seoul with Cash on Delivery.

Is COSRX BHA Blackhead Liquid right for your skin?
Best for
- Blackheads on the nose, chin and forehead
- Oily and combination skin with clogged-looking pores
- Acne-prone skin that wants a pore-clearing step, alongside a gentle cleanser
- Rough or bumpy texture that wants smoothing
Skip it, or patch-test first, if
- Your skin is dry, very sensitive or the barrier feels damaged: build it up with a gentle routine first, then patch-test
- You already use a strong AHA, BHA or prescription retinoid: do not use them on the same night
- You are allergic to aspirin or salicylates: ask your doctor before using any BHA product
- You will not wear sunscreen every day: exfoliated skin is more sensitive to the sun
How do you use COSRX BHA Blackhead Liquid?
Evening
- Cleanse with a gentle face wash and pat your skin dry.
- Apply toner if you use one.
- Put a few drops on a cotton pad or your fingertips and smooth over the face or just the T-zone, avoiding the eyes and lips.
- Wait a few minutes, then apply a soothing essence and moisturiser, such as COSRX Advanced Snail 96 Mucin Power Essence.
- Start 2–3 evenings a week and increase slowly only if your skin stays comfortable.
Do not use it on the same night as retinol, retinal or other exfoliating acids. A little tingling at first can happen; stinging, redness or peeling mean you should use it less often. Wear a broad-spectrum SPF 50 sunscreen every morning.
What are the key ingredients in COSRX BHA Blackhead Liquid?
- Betaine salicylate (4%) — a BHA made from salicylic acid and betaine; it works inside oily pores to loosen blackheads and dead skin, in a gentler form
- Willow bark water — the base of the liquid; willow bark is a natural source of salicylates and gives a light, watery feel
- Niacinamide (vitamin B3) — helps oily skin look more balanced and the tone look more even
- Sodium hyaluronate — a form of hyaluronic acid that adds light hydration, so the liquid feels less drying
Is BHA Blackhead Power Liquid a toner or a serum?
It sits between the two. The texture is watery like a toner, but it is a leave-on exfoliant, so it does more than a basic toner. Apply it after cleansing and any hydrating toner, let it absorb for a few minutes, then follow with essence, serum and moisturiser. Unlike a toner, it is not meant for every morning and evening at first: start 2–3 evenings a week and build up only if your skin stays comfortable.
COSRX BHA Blackhead Liquid vs COSRX Salicylic Acid Cleanser: which should you choose?
| COSRX BHA Blackhead Liquid | COSRX Salicylic Acid Cleanser | |
|---|---|---|
| Format | Leave-on liquid exfoliant | Rinse-off foaming cleanser |
| BHA | 4% betaine salicylate | 0.5% salicylic acid |
| Contact time | Stays on the skin | Rinsed off within a minute |
| How often | Evenings, starting 2–3 times a week | Once or twice a day |
| Best for | Stubborn blackheads and rough texture | Daily cleansing for oily, acne-prone skin |
Choose the BHA liquid if blackheads and clogged-looking pores are your main concern and you want a leave-on step. Choose the salicylic acid cleanser if you want a simple daily face wash for oily, acne-prone skin. They can be used in the same routine, but start one at a time and cut back if your skin feels dry or irritated.
How can you tell if your COSRX BHA Blackhead Liquid is original?
- The liquid should be clear and watery with almost no smell; a cloudy, coloured or perfumed liquid is a warning sign.
- The box should be sealed, with the ingredient list and COSRX details printed clearly; blurred printing or spelling mistakes suggest a copy.
- A price far below other trusted sellers usually means old stock or a fake.
- Check the batch code printed on the box and the bottle: the two must match, and the code should look printed, not stuck on. Every unit we sell is batch-code checked on arrival in Seoul, and we verify any code for free — see how to check if Korean skincare is original.

Our stock is bought from official COSRX channels in Seoul, every unit is batch-code checked on arrival and shipped from our Seoul warehouse.

How do I use COSRX BHA Blackhead Power Liquid?
Use it in the evening after cleansing and toner. Put a few drops on a cotton pad or your fingertips and smooth it over the face or just oily areas, avoiding the eyes and lips. Wait a few minutes, then apply essence and moisturiser. Start 2–3 evenings a week, build up slowly, and wear a broad-spectrum SPF 50 sunscreen every morning.
Is betaine salicylate the same as salicylic acid?
They are related. Betaine salicylate is made by combining salicylic acid with betaine, a gentle ingredient from sugar beet. It works on oily pores in a similar way to salicylic acid but is usually felt as milder, which is why it suits many people who find salicylic acid drying. It is still an exfoliant, so start slowly and wear sunscreen daily.
How long does COSRX BHA take to clear blackheads?
Skin often feels smoother within a couple of weeks. Blackheads and clogged-looking pores usually look clearer after several weeks of regular use, a few evenings a week. Blackheads come back if you stop, because pores keep making oil, so think of the liquid as an ongoing step. Squeezing blackheads while you use it can irritate skin and slow things down.
Can I use COSRX BHA with retinol, vitamin C or niacinamide?
Niacinamide and hydrating serums are fine on the same night. Keep retinol, retinal and other exfoliating acids for different nights, because together they can irritate and dry the skin. Vitamin C is easiest in the morning, with the BHA at night. If your skin stings, turns red or peels, cut back to fewer actives and use a soothing moisturiser.
Is COSRX BHA good for sensitive or acne-prone skin?
Many acne-prone skin types use it, because BHA works inside oily pores, and betaine salicylate is a milder form. Sensitive skin should be more careful: patch-test first, start once or twice a week and use a calming moisturiser after. Some people get a few extra spots in the first weeks; if irritation or breakouts keep getting worse, stop and ask a dermatologist.
