COSRX BHA Blackhead Power Liquid


COSRX's Power Liquid is a powerful BHA skin treatment that is designed to prevent the formation of blemishes before they even occur. 

Ready for a change? COSRX BHA Blackhead Power Liquid is here to make it happen.

Unlike most Western BHA products, COSRX BHA Blackhead Power Liquid is formulated using betaine salicylate rather than the more common salicylic acid.

We love it because it's not as drying as other BHA products. 



  • Contains 4% betaine salicylate
  • Recommended for blackhead sufferers
  • All-natural BHA Blackhead Power Liquid
  • Clear texture that is slightly thicker than water
  • Contains star beauty ingredient willow bark water
  • Gently exfoliates for a brighter, more even skin tone
  • Helps to achieve and maintain smooth, soft skin
  • Deep cleanses to flush out your pores



BHAs or Beta Hydroxy Acids work by “de-gunking” your pores.

Since BHAs are oil soluble, they penetrate through the oil that’s clogging your pores and exfoliate all of the dead skin cells that have built up inside. This is why BHAs are recommended for those with oily skin. BHAs also help reshape your pores, and allow your other skincare products to better penetrate your skin.

BHAs can assist with oily or blemish-prone skin and those who suffer from blackheads and white bumps.



COSRX Blackhead Power Liquid is based on willow bark water rather than plain water. Willow bark is a natural source of BHAs, which has exfoliant properties.

It also contains 4% betaine salicylate.

Do not use if: You are sensitive to betaine salicylate or anything else in the ingredients list. 


For best results, combine with a low pH cleanser like Tosowoong Enzyme Powder Wash.

If it’s your first time using a BHA product, start off slowly, using the product once a week.

1 After cleansing (and after Vitamin C serum if you use one), apply a small amount of COSRX BHA Blackhead Power Liquid to the target area morning or night.

2 Spread out an even amount to the rest of the face, avoiding the eye area.

3 Focusing on the target area with blackheads, massage lightly and allow full absorption.

4 For best results, wait 20-30 minutes before applying any other products to allow the acid to take effect without being prematurely neutralized.

NB. If you use COSRX BHA Blackhead Power Liquid in the morning, make sure you apply sunscreen afterwards

    It works!!

    I bought the Cosrx BHA liquid after some research comparing it to Paula's Choice BHA and im really glad i went with this one! I was having a hormonal break out and i heard that certain products can make your skin purge so i was expecting that and it did happen within the first week. But after a couple more days my breakouts completely calmed down and 2 weeks later it even got rid of the tiny bumps around my face!! Ive been using it for roughly 4-5 weeks now and my skins texture has definitely improved, although i get a pimple it doesnt stay for long anymore and it even got rid of the tiny bumps on my temples which i could never get off before! But with my blackheads i feel like its taking a little longer to get rid off compared to my breakouts but i'll keep using it!!



    Hi Nicole! Thanks so much for leaving such a detailed review of COSRX's BHA Blackhead Power Liquid. Glad to hear it compares favourably to Paula's Choice - STYLE STORY

    Only been using it for a couple of days and I can see my skin starting to purge but I read that would happen with this product. It leaves such a nice glow with my skin afterwards, will have to wait and see what it does to my skin but looks promising so far



    Thanks so much for your review, Jack! Glad to hear you're off to a good start with COSRX BHA Power Liquid - STYLE STORY
