After using it for a couple of weeks, i've started seeing a difference in the amount of whiteheads

I use this more for the fact that it is an AHA and less for whiteheads, so I can't say if it really helps with them or not. But it does make the skin smoother.

Very good in my exfoliating days. Worth a try.

Hi! I have just received this product. I bought it because of the good reviews I’ve been reading about it. I will try it the soonest and hopefully it will also have a very nice effect on my face. Thank you Style Korean!

This product works great! Really helps smooth out my skin. I had a lot of Whiteheads but it is starting to disappear. It can sting a bit, but not bad. I would use it everyday but I obviously don’t because it’s not recommended. Another great product by COSRX!!

This product effectively removes new whiteheads build up and the area feels smooth and bright after. It also removes the small bumps (oil build up) on my forehead.

Prevented my breakouts and reduced my whiteheads. Cleared my skin.

This is on my top 10 favorites and can't live without products. It really helps keep the acne and bumps away. I notice the difference when I stop using it for a few weeks.

I got this exfoliator because the CosRx BHA Power Liquid got really good reviews and I figured the AHA should work well with it. I have oil combination skin and I think it seems to be working, but it'll take more time to know it it really is working or not.

my sister and I use it together both for our face and our arms. We both have Keratosis Pilaris so our skin is always a bit rough on the arms. I read online that this might help and it did help with the bumpiness on the skin. (the redness remains though but that is okay since this product isn't even meant for this purpose but I thought I'd let those know who have the same problem) As for the face, it helped reducing imperfection on the forehead and the nose (so basically the T Zone) it is not harsh. i'd recommend using it at night only to make sure that no UV light interferes with the product.

Not really sure if this product is working. I’ve used couple of times. But not a big difference.

I use this exfoliating liquid a few times a week depending on what my skin needs and I can't complain. It does the job well, cleans my pores, doesn't burn or irritate my skin. The price is super budget, but this product compares to the other European AHA exfoliators I've used.

My skin type: acne prone, dry, easily get clogged pores

 

I used this with the CSORX BHA together for 1-2 week. Did not see any result. When my acne got worse (probably from stress, no sleep, eating too many junk food and not because of the product), I tried applying this to attempt to reduce the pimples. However, the pimples got bigger and redder. So, I stopped using them. I believe this would be helpful if you DO NOT USE ON REGULAR BASIS, and use maybe once per week. 

 

I love this AHA 7 Whitehead Power Liquid. It provides excellent results.

I think it is a good product. I recommend

My favorite skincare product! It helped even out around 95% of my bumps and made my skin super smooth. Smells kind of strong like alcohol, but that is expected because of the AHA.
 

Light texture, very watery and absorb very quickly. The scent is not very pleasant but I'm ok with it. I use once a week and the effect so far is good. Those with sensitive skin should use this with caution. Good product COSRX overall. 

 

Good chemical exfoliant. I already purchased it a couple of times. 

I was worried at first that it would irritate my skin but it didn't at all. It didn't instantly get rid of whiteheads but with constant use it has really diminished them.

This formula is pretty strong. At first I only used a little pit on a cotton pad and didn't see much of a result, but the second time I actually soaked the cotton pad more and could see a difference. The second time I could tell that my pores had shrunk, but it did leave me some redness on my nose the next day so I would just be careful about the amount you use. 

This helps my skin by preventing acne, but I don't feel that it exfoliates well.

Maybe it takes time and after use this product must apply sunblock when going out

It helps my bigger whiteheads but it takes some time to work.

I use it before applying clay mask. First I steam my face to open up the pore, then apply this and the BHA liquid and wait for about 20 min. After that I apply the clay mask. Together they help reduce sebum production and reduce number of blackheads and whiteheads. Note: you will need to use it more than a few times to see results. So be patient if you don't notice immediate difference.

COSRX BHA gave me chemical burn, so I did not have high hopes for COSRX AHA. To my surprise, I find it quite gentle and it clears most of my white head.

This did not work well for me as i have very stubborn whiteheads maybe it would work on others.

Helps my skin bee smooth. Use with caution not to overexfoliate and always use sunscreen.
 

I love it. Not so expensive as well!!! :) :P 

I purchased this AHA because many people said it made their skin very smooth. Well, in my case, it does get rid of some dead skin cells, but a few dry patches still remain present. However, I have noticed that it works really well if you put it directly on the breakouts! Oh, and it performs wonderfully when it comes to treating body acne.

it really is a power liquid, I use this 2-3 times per week and it keeps pimples away! it also helps against whiteheads already on my face too. on the directions it says not to use with any other bha and aha products so I alternate using my other cosrx skincare when I don't use this
