Finally! A product for clogged pores!
I have needed this product my whole life. No matter how much a double cleanse, hydrate, get facials with serious extras, etc, I’ve always had an issue with whiteheads and blackheads. This product really works! I did have some very mild purging the first couple of days, but it went away. I used this every other night and my whiteheads have improved to the level of being gone. This after 3 weeks. Pores are smaller because they are clean and empty. Absolutely recommend this product for anyone who has these issues. It works great, while not drying your skin out, leaving a clean, translucent looking radiance. Going into my rotation and staying there. .

So far - super effective
This product has been able to visibly reduce white heads, and help to shrink pore sizes. You can’t beat this price either

COSRX AHA7 WHITEHEAD POWER LIQUID
I really love this product, I used it on a whitehead on my nose . The whitehead was gone in a few days and no marks or scars. My skin looks great. I highly recommend this product.

hydrating exfoliant
This was a good exfoliant because it wasn't overly drying but it was not enough for oily congested skin. Better for normal skin types.

Nice BHA Serum

Beware of Purging
I have sensitive skin that's prone to acne and purged a lot when I first started using this. I didn't, however, experience any of the burning that some others mentioned. The fragrance is odd, but doesn't last. Cosrx products seem to be well-loved so I'll continue using this and hope to see some improvement with these pesky whiteheads.

Great product
I’ve only been using this for a couple of weeks (and every 2-3 days, at that) but I’ve already noticed a reduction in clogged pores. It stings a bit sometimes for a few minutes after application, and it’s also a teeny bit drying, but all in all it’s very tolerable and worth the effort of adding a little extra moisturizer. My skin gets congested and irritated very easily, so it’s nice to find a product to address the one without exacerbating the other. (I also recently discovered the COSRX acne patches, which are amazing - new favorite brand?)

Awesome AHA
For the cost of this product I was quite surprised at how effective this AHA was! I not only use it on my face but also on ingrown hairs that I get after shaving or hair removal and it does the trick without being too harsh on my skin. I have really oily but dehydrated skin, this product brought balance back to my skincare routine.

Does what it says
Very good treatment, effective. Have been using it for a week, can already see reduction in irritation of the blemishes. Does not dry out the skin too much, but definitely recommend using an appropriate moisturizer afterwards. There is a prickling feeling on the skin after using it, but it goes away in about 30 seconds.
