This pore-clearing treatment has garnered a worldwide cult-following for its powerful exfoliating benefits. Infused with 4% betaine salicylate, it contains a gentle type of beta-hydroxy acids (BHAs) that don’t just work on the surface of your skin, but seep into pores to clear away deep impurities. This prevents excess oil from turning into blackheads, so your skin looks spotless—inside and outside.

Its gentle form of BHAs are powerful, yet non-irritating on the skin. With its ability to penetrate into deeper crevices, it removes impurities that other skincare products can’t reach.

HG for BHAs

On using this for every routine, I had to reapply this product numerous times before my SFs were gone! Don't get me wrong, I used little pumps in applying it. I just wanted to maximise its contents because COSRX's BHA Blackhead Power Liquid is the best 😭 every drop counts

less visible pores

I've got my order sept 9, I used this only twice since. I expected to see raging purging due to fact that I have not been using bha, i've only used aha. Precovid I regularly have my facial so I have not have facial since ecq. I guess this is a good alternative for facial extractions of blackheads. This is more gentle I think than having your facial but the result may take a month or two. Overall, my pores are less visible but I got a huge cystic acne on my chin. I dont mind I expected it anyway. Try this as an alternative to facials.

Another holygrail product for me! ❤

It's my first time using this product, but since I'm already using Vitamin C serum on a daily basis and my skin is acquainted with acids, I started to use this once a day. In just 2 days of use, it made my pores look smaller, and started purging deeply seated blackheads. I alternate this with Vitamin C serum so I won't deal with irritation. It didn't make my skin too dry unlike other acids, it doesn't sting too. It will stay in my skincare staple forever!

No power

The product seemed very promising. Unfortunately it didn’t do anything, not even a slight effect or result. I really wanted to love this and be like “Finally a product that helps get rid of my blackheads!” Not worth spending on. I finished an entire bottle, focused on my t-zone area. Positive note, it didn’t break me out.

It works!

We used this after trying the Poreless Power Liquid. This is waaay better. We have combination and oily skin. It works for us both. We use it twice a week. His pores do seem smaller (on the cheeks, not the nose) and our skin feel smoother after a month of use. Try it!

I was expecting more from this item. It claims to “gently exfoliate” and “gently lift blackheads” so i gave it a shot. I use it like 3x a week, but i did not see my blackheads disappear. I dont have much, but i was just a bit OC about it and waiting for it to work
