COSRX - BHA Blackhead Power Liquid (100ml)

COSRX BHA Blackhead Power Liquid is the oil-soluble half of the exfoliant pair — the one that actually gets inside a clogged pore, and the right choice for congestion rather than surface texture.

BHA Blackhead Power Liquid at a glance

Blackheads, and the thing most people mistake for them

BHA is oil-soluble, and that single property is why it suits congestion. Where an AHA works across the skin surface, a BHA can travel into a pore filled with sebum and break down the plug from inside. If your concern is blackheads, bumpy congestion or an oily T-zone, this is the more appropriate of the two acids.

Now the part product pages usually skip. Most of the small dark dots on the nose are not blackheads — they are sebaceous filaments, a normal structure that lines every pore and channels oil to the surface. Everyone has them, they refill within days no matter what you do, and they cannot be permanently removed. A BHA will empty and soften them, so the nose looks visibly clearer, but they will return. That is not the product failing; it is normal skin.

Genuine blackheads — larger, darker, oxidised plugs — do respond properly, but slowly. Give it six to eight weeks of consistent use before judging. Squeezing and pore strips give a faster result and a worse one, because both damage the pore wall and tend to make the opening more visible over time.

How to use it

1. Start twice a week, at night, on clean dry skin.
2. Apply a thin layer to congested areas with hands or a cotton pad, avoiding the eyes.
3. Wait a few minutes, then moisturise.
4. Build to every other night if tolerated. Daily use suits very few people.
5. Wear sunscreen every morning.

Frequently asked questions

Should I use this or the AHA 7 Whitehead Power Liquid?

Use this one for blackheads, clogged pores and oily skin. Use the AHA 7 for rough texture, dullness and uneven tone. Despite its name, the AHA is the weaker choice for pore congestion.

Can I use both AHA and BHA?

Yes, but not on the same night when starting out. Alternate them, and only after your skin tolerates each one separately.

Why do the dots on my nose keep coming back?

Because most of them are sebaceous filaments, not blackheads. They are a normal part of pore anatomy and refill continuously. A BHA keeps them less visible; nothing removes them permanently.

How long until I see a difference?

Oiliness and small bumps often improve within two to three weeks. Established blackheads take six to eight weeks. Anything promising overnight results is overselling.

Is it safe for sensitive skin?

BHAs are generally better tolerated than strong AHAs and have some soothing properties, but any exfoliant can irritate. Start once or twice weekly and patch test first.

Can I use it with retinol?

Alternate nights rather than layering. Combining an acid and a retinoid in one routine is the most common cause of a damaged barrier.

Should I avoid it during pregnancy?

Salicylic acid and related BHAs are often advised against in pregnancy, though topical exposure is low. Check with your doctor or midwife rather than relying on general guidance.
