COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner 3.38 fl.oz / 100ml, Korean Toner, Blackhead Remover, Pore Minimizer for Enlarged Pores, for All Skin Types, Korean Skin Care

This is the single most effective treatment I’ve ever used on my skin. I couldn’t believe it. The day I got it, I used it as my nighttime toner, and woke up next morning with noticeably clearer skin and smaller looking pores. I’ve been using it for about two weeks now, and it has made such a huge difference for me. My acne scars have faded a bit, I have no black heads, and the texture of my skin generally looks so much smoother. I didn’t know anything could work this well for my skin. HIGHLY recommend giving it a try

I was hesitant to buy this because there are so many products that claim the same results. Still need to evaluate for long term results - but it immediately felt nice going on and my skin did feel less oily yet moisturized from the first day.

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!

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!

This product has made a huge difference in my pore care routine. I highly recommend it.

cosrx is my favorite skin care brand at the moment.. paula's choice who???? never heard of her. the consistency of this is more like a serum than a toner. it feels a lot like snail mucin and galactomyces serum, which i enjoy. the very best exfoliation but not drying. korean skincare is on another levellll!

Feels nice and makes me skin glow. But I've tried it off and on for a year now and it's never cleared anything. If anything it bring all my blackheads to the surface. But doesn't stop them. And my acne almost feels worse. But I'm still trying it cause it does feel nice.
