    • Finally a pore treatment that actually delivers!
I’ve tried so many "pore-minimizing" products that did nothing but dry out my skin, but this COSRX toner is the real deal. After using it for a few weeks, the pores around my nose and cheeks look significantly smaller and much "cleaner." It’s incredibly effective at clearing out stubborn blackheads without any harsh stinging or irritation. The texture is like water and absorbs instantly, leaving my skin feeling smooth rather than greasy. If you struggle with enlarged pores or an oily T-zone, this is a total game-changer for getting that "filtered" look in real life. Highly recommend! ... show more

    • Good for acne prone skin! Or at least mine haha
Great, I was having so much trouble finding effaclar K+ from LRP, because it was so good for my acne and breakouts. I actually was a little nervous because I break out so easily. But this has done wonders, the first time I used it it felt oily to the touch and got scared, but it is not oily, and it dried very quickly! ... show more

    • It works!
Started using this following the very popular grit method for getting rid of subcutaneous filaments. As stated in the method i apply, allow it to sit on my skin for 20 minutes and then apply a clay mask and an oil cleanse. Using this protocol ive had pretty great success keeping my skin clear and smooth of those pesky little bumps. I also use retinal nightly which has helped a lot but i mention it to note if u are using retinal you should definitely take a day off to when using this product or you risk irritation and skin barrier problems. This is definitely gentler than salicylic acid while being comparatively as effective in my experience. Overall if you are looking to clear your skin of filaments, this definitely works. ... show more

    • Helpful, but not a standalone solution
Review Image by Vanessa
I’ve been using this product for about 6 months, and I think I can give a pretty solid review. I have combination, comedone-prone skin, and the main reason I decided to try this was to get rid of my closed comedones. I do think this is a good product in the sense that I saw some improvements in my skin, for example, it helped a lot to minimize the appearance of sebaceous filaments, but I feel this product alone is not enough to achieve the results I was hoping for. When I started using this, I experienced a LOT of purging. I don’t think I’ve ever had so many closed comedones concentrated on my skin in my life. I think this was totally normal since I wasn’t using any kind of exfoliators for months before I started using this, so my skin turnover was kind of “resetting” and bringing out all the congestion from deeper layers. I experienced this for about 3 months, and then I started to notice that many of the comedones began to resolve and dry out, which is when the purging basically ended. However, since I had so many comedones, I decided to get professional facial extractions instead of waiting for them to dissolve on their own, because I honestly couldn’t handle having so many bumps anymore. After the extractions, I wanted to test whether this product could prevent new closed comedones from forming. The answer was basically no, because my comedones are mostly hormonal, so every time I got my period, I would get around five new ones. The thing is, this product does help treat those comedones and eventually helps them resolve, but it works very, very slowly. In my case, the product hadn’t finished getting rid of the old closed comedones when I started getting new ones. What I mean is that this product does work, but very slowly, and for someone like me with very stubborn comedones, it wasn’t enough on its own. What actually helped my skin a LOT, and when I finally started seeing the results I was hoping for, was when I incorporated azelaic acid into my routine and alternated it with this product. When I did that, I noticed how much faster my closed comedones started to resolve, and my skin improved a lot. I’m using the Anua azelaic acid, just in case you’re curious and want to try it too. So in conclusion, this is a good product, but if you have very stubborn, hormonally driven comedones, this product by itself probably won’t be enough. That doesn’t mean the product is bad, it just means some skin types need to try different things until you find what truly works for you, and that process takes time. I hope this review was helpful! ... show more

    • Gentle Exfoliation and Leaves Skin Feeling Smooth
Review Image by Tania Mora
Review Image by Tania Mora
I’ve had a good experience with this BHA liquid. The texture feels lightweight and absorbs well without feeling heavy or greasy. It fits easily into a skincare routine and feels comfortable to use a few times a week. With consistent use, my skin felt smoother and looked more refreshed overall. I also liked that it felt gentle compared to stronger exfoliating products and layered well with moisturizer. Overall, this is a nice option if you’re looking for a lightweight exfoliating product that leaves skin feeling cleaner and smoother over time. ... show more

    • Dubious at first, THRILLED at last
I bought this because I have deep pores on my nose area that constantly get clogged and look so unattractive. The first couple times I used it I didn't use a moisturizer at all that day, and my skin dried up and flaked, it was awful! I soon figured out that if I put it on first thing in the morning, waited a few minutes while I brushed my teeth and did other morning steps, and then put on moisturizer, that solved that. No more dry skin. Here's my application routine: 1) Wash and dry face 2) Pump one squirt of BHA Power Liquid in palm 3) Apply liquid to face using 2 fingers of the opposite hand, dipping into palm to get more (T-zone/break-out spots) - I do not used a cotton pad because it soaked up and wasted tons of liquid 4) Let sit for 10-15 min, then apply moisturizer (do not rinse) 5) Repeat morning and night After the first month, I honestly didn't see much of a change. I expected it to burn more, but it mostly felt like nothing, which was slightly disconcerting at first. I might have stopped using it, except that I had so much left and seemed like a waste not to keep trying. About three months in, I suddenly realized what a dramatic shift had started happening. I typically have maybe 5 pimples at any given moment, and then I get a monthly hormone-related breakout on top of that. Since I got past the 6-8 week mark of using BHA Power Liquid, I haven't had a major breakout in 8 months!! It's not just my blackheads that started clearing (FYI, those took 3-6 months to actually disappear completely), it's my whole face that has improved! I no longer have my steady pimples, either. I'll get really small spots here and there, and they clear up so quickly that even my husband doesn't notice them. You guys, this stuff is incredible! I realize that everyone's skin reacts differently, but this stuff is a dream for mine! Three times I've forgotten to bring it on long vacations (2 weeks) and each time I started breaking out toward the end of the trip, but cleared up when I got back to my routine. I'm buying a second bottle for my travel bag right now (the size is US carry-on approved--woohoo!) And on top of everything, the one bottle is on course to last me for an entire year. I've recommended this to at least a dozen people and am buying to the AHA Power Liquid right now to see how that works on me. ... show more

    • Not great for dry skin

Review Image by Kiki J
I cant say that I love this product. It is one of the most drying BHA’s I’ve ever used. No matter how much I lather up after use, my face will feel extra dry over the next couple of days. I think this might be better for someone with oily skin. I will continue using to look for improvements in overall texture, it does seem to do the job when penetrating deep but for me the cons outweigh the pros. ... show more

    • Great for pore reduction.
This product is wonderful. I thought that it would be slimy but it is a light consistency that dries quickly. Which is great because I use it in the morning and it needs to dry before I apply my sunscreen. I've been using this for about 2 weeks now and I have already seen a reduction in the size of my pores in my T zone. ... show more
