About this item

  • 4% betaine salicylate: a gentle BHA that slowly dissolves blackheads and pore build-up without harshness.

Description

COSRX BHA Blackhead Power Liquid helps clear pores and smooth skin with gentle, effective care. This Korean beauty favorite uses 4% Betaine Salicylate to slowly dissolve blackheads and excess oil without harshness. Perfect for oily, combo, or acne-prone skin, this liquid works to unclog pores, balance oil, and brighten your skin over time. A gentle yet powerful friend for those dealing with bumpy texture, dullness, or stubborn pores.

Why Your Skin Will Love This Gentle BHA

This BHA liquid works differently than harsh scrubs. It gently breaks down the build-up in your pores while keeping your skin's moisture safe. The star ingredient, Betaine Salicylate, is like a gentler cousin to regular salicylic acid, making it perfect for even sensitive skin types.

Beyond just tackling blackheads, this power liquid helps balance your skin's oil levels and smooth out rough texture. Many users notice their skin feels less oily throughout the day and looks clearer over time. The formula is alcohol-free and fragrance-free, so it works without the sting or dryness that some BHA products cause.

The Good Stuff Inside

Willow Bark Water forms the base of this formula instead of plain water, bringing natural calming benefits to your skin from the start. The 4% Betaine Salicylate works slowly to clear pores without being harsh.

  • Niacinamide brightens and helps balance oil
  • Sodium Hyaluronate keeps skin hydrated while you exfoliate
  • Panthenol soothes and helps repair your skin
  • No artificial fragrance, parabens, or alcohol

This clean list is why so many people with sensitive skin can use this BHA when other exfoliants feel too strong. COSRX keeps it simple with just what works, nothing extra that might upset your skin.

How It Helps Your Skin

This power liquid works on many skin concerns at once. First, it tackles clogged pores by gently dissolving the mix of oil and dead skin cells that form blackheads. As these clear up, your pores look smaller and skin feels smoother.

It also helps keep new breakouts from forming by keeping pores clear. Over time, users notice their skin tone becomes more even and bright. Since it balances oil without stripping, your skin stays comfortable - not too dry or too oily. Those with combo skin love how it works on oily areas without making dry patches worse.

How to Make It Work for You

Start slow with this BHA liquid to let your skin adjust. Apply 3-5 drops to clean, dry skin 2-3 times weekly at night. You can pat it on with your fingers or use a cotton pad. Wait about 20-30 minutes before applying your next skincare step for best results.

  • Morning after: Always use sunscreen (BHAs can make skin more sun-sensitive)
  • Pair with: Hydrating toners and moisturizers
  • Avoid using with: Other exfoliants like AHAs or retinol on the same night

As your skin gets used to it, you can slowly use it more often if needed. Most people see the best results when using it 3-4 times per week as part of their evening routine.

Real Results (With a Little Patience)

While some products promise overnight miracles, this BHA liquid is honest about timing. You'll likely feel smoother skin within the first few uses, but seeing real changes in blackheads takes 4-8 weeks of regular use.

This slow, steady approach is actually better for your skin in the long run. Users report fewer blackheads, smoother texture, and less oiliness throughout the day. The 100ml bottle lasts about 3-4 months with regular use, making it a good value for the results it delivers.

Many customers with sensitive skin who couldn't use stronger BHA products find this formula works without causing redness or irritation. The gentle approach means your skin keeps improving over time without the setbacks of over-exfoliation.

Ready to help your skin breathe easier? Add COSRX BHA Blackhead Power Liquid to your routine and experience the calm, clear difference. Your pores will thank you, and you'll love watching your skin transform day by day. Treat yourself to this gentle yet effective care – because clear skin should feel good, not harsh.

How to Use

Apply 2-3 times weekly in the evening, using 3-5 drops on a cotton pad or in your palms after cleansing and toning. Ensure the skin is dry before application. Follow with a moisturizer and SPF in the morning. Avoid the eye area during application.

Store the product at room temperature away from sunlight. It has a shelf life of 12 months unopened and 6 months after opening. With consistent use (3 times weekly), expect noticeable results in 4-8 weeks, including reduced blackheads, fewer breakouts, improved pore appearance, and a brighter complexion. Suitable for oily, combination, acne-prone, and sensitive skin types, especially during summer and winter when paired with appropriate hydrating products. Adjust usage if skin becomes over-exfoliated or very dry, and avoid using other active exfoliants on the same night.

Betaine salicylate 4% · Willow bark water · Fragrance-free

The gentler way to keep pores clear.

4% betaine salicylate on a willow bark water base — a BHA liquid built for regular use rather than an occasional strong treatment.

Congested skin4% betaine salicylateFragrance-free
COSRX Exfoliator 100ml COSRX BHA Blackhead Power Liquid

What does it do?

Slow beats strong.

Betaine salicylate is a milder relative of salicylic acid — the reason people who can't tolerate other BHAs get on with this one.

Keeps pores looking clearer

4% betaine salicylate works gradually on the build-up that makes pores look bigger.

Smoother-feeling texture

Regular use helps the bumpy, rough feel across the nose and chin.

Comfort built in

Niacinamide, panthenol and sodium hyaluronate sit alongside the acid so skin isn't left dry.

What's in it?

Willow bark water, not plain water.

Alcohol-free and fragrance-free, which is unusual for a BHA.

How does it feel?

A thin layer, at night.

Smooth a thin layer over clean, dry skin and let it settle before the rest of your routine. Start a few nights a week and build up.

Choose your acid

Which power liquid?

COSRX splits its acid liquids by what they target — pore build-up, surface texture, or both.

Is it for you?

For pores that never quite look clear.

Consistency does more than strength.

  • Congested, bumpy-feeling skin
  • Oily and combination skin
  • Anyone who reacts to stronger acids
  • Night use — daily SPF matters with any acid
Already-dry skin, worried an acid would make it worse

The texture of the product is really pleasant to me; it's very smooth and not too watery. I apply one pump using just my fingers. I did not find it to be drying at all which was one of my concerns considering how dry my face felt.

A harsher BHA that limited how often I could use it

… i started with using … BHA, but it was pretty harsh - it kinda stopped me from using it too often. i can use cosrx in the morning and in the evening no problem.

Sensitive skin, wary of using an acid too often

I use CosRX Bha every 2-3 days and my skin is really sensitive. Sometimes I will only put it on the T-zone too. Its an extremely gentle formula so you can do this!

A thin layer, a few nights a week.
