    Miracle Worker!!
    January 25, 2019
    I bought this essence to target my black heads. I was not expecting much as I have tried many things and nothing seemed to work, but boy I was wrong! This essence has done wonders to my skin! It has not only reduced my black head by 70% it has also helped reduce the visibility of my pores, you can see for yourself in the picture. It has also helped in refining my bumpy forehead texture. This product is no joke it does what it claims. I started using it first once a week and I increased the usage to 2/3 times a week. You can start seeing a difference after 5 uses or so. In addition, I decided to test this essence on my back in hopes that it will refine my skin texture and get rid of the bumpy texture on my back and guess what? it actually worked my back is now soft to the touch. I love it. Highly recommend!!

    Okay it’s been a long time since I’ve written a rave review about a product. I did some research into this and found that it’s pretty popular across lots of skincare blogs so I decided to check it out. I have never used a BHA on my face before and heard the wonders they do for pores. This serum not only erased my blackheads but shrunk most of my large pores down to nothing- and KEPT them that way. I can’t get over how great my skin looks. I have been into skincare for a while but I didn’t know this kind of breakthrough for my skin was possible. I just thought I was doomed to having large pores. the best part about this product is that the ingredients list is short and sweet. Below I listed the active ingredients and their main functions. Hope this helps if you’re on the fence!

    It contains willow bark extract, betaine salicylate (a gentler alternative to salicylic acid derived from sugar beets), niacinamide (increases collagen production), hyaluronic acid (binds moisture to the skin), arginine (amino acid with antioxidant properties,) and panthenol (sort of a part of the vitamin B complex.)

    my skin is pure
    July 2, 2019
    my skin has been completely blackheadless on my nose area since i started using it, my chin too, but it won't prevent breakouts.

    however it really gave my skin a very clean finish and ive started my pores also minimizing in size since ive started using it because of this very gentle non-physical way of removing deep settled dirt.

    Love this treatment! It really does dissolve blackheads, way better than ripping them out with a Bioré strip or one of those awful black masks.

    still the best (3 month update)
    May 28, 2019
    this still works great. now i use it about 2 to 3 times a week depending on how my skin looks but i do not use any skin care after it. i put this on after cleansing and wait for 10 minutes then i put on a light moisturizer (if needed) and sleep. i have noticed it works even better this way. also i should add that as of now (about 3 months of using this) none of the pores feel congested and i have no more bumpy hard blackheads anywhere on my face (which were a huge problem for me for about a whole year). only thing i would say is to start with a product with less percentage of BHA and then slowly build it up to this because this is very concentrated, i used this after the aha bha treatment toner so my skin didn't notice anything different. my sister however has never used BHA and she felt tingling with this product for a long time (no otherwise bad effect though)
    finally tried it and loved it

    i have oily combination skin which has recently become dry (also oily sometimes) acne prone (i shifted cities) and suddenly i have to rethink everything about my skincare. i was looking for a good chemical exfoliant so i found the AHA/BHA clarifying toner from cosrx which helped wiht my dry flaky skin but it didn't do that much for my clogged pored which continue to become painful acne and blackheads. i started to get clogged pored on the outer parts of my cheeks, my jaw line and chin and forehead (everywhere i never had them basically) so i bought this and IT DOES WORK. i only use it 2 times a week and it made such a difference in my skin. even though i have used it like 4 times until now i can already say that this is great. it does not sting or anything. i use it after toner an spread it on my face with a cotton pad wait for 5 to 10 minutes and then do the rest of my skincare and sleep.

    Effective and efficient

    This essentially puts all those fad blackhead removal charcoal based products to shame and actually destroys those pesky blackheads pretty much straight off the bat (it’s THAT good). Now i'm going to give you a friendly warning, this stuff is super watery and comes out startlingly fast. COSRX seems to specialise in giving you great value for money products, because you only need about a 5P/20P coin sized amount here. Spread it thinly onto affected areas (basically your T-zone: nose and forehead). Massage into skin until dry. The results are truly incredible, my skin cleared up after my first day of usage, leaving my nose and forehead almost entirely blackhead free.

    Holy Grail

    I have oily acne prone skin. This has helped me to get rid off the blemishes and acne scars. My skin is so soft and smooth after using this. Remember the sun screen when you are using this!

    HG product!
    August 27, 2017
    I really crave this product. My closed comedones finally are disappearing using this product three/four time a week. I have a really sensitive skin and this product doesn't irritate and doesn't cause redness. A must-have in every beautycase!! After finishing the cleansing step, apply the toner, wait until it dries and then use the cosrx's BHA. Wait at least 20 minutes before to apply the rest of your routine.

    I love this power liquid. I used this after the toner from the same brand. After using this combo i started to noticed that i have less breakouts and my acne scars are quite fading. I also noticed that i have less blackheads and whiteheads. It's watery, with a bit of smell but not prominent it will be gone after a few seconds, not sticky and doesn't sting at all. God for oily acne prone skin like me. Definitely would repurchase and highly recommend this.

    Absolutley love this product
    September 15, 2018
    I initially bought this specifically for the tiny blackheads I was getting on my nose. One night I had extra product on my hands so rather than waste it decided to just smear it all over my face and neck.

    The next day I awoke to find that every little blemish I had (on side of face and chin) had literally vanished. I told a friend about this, she ordered some and low and behold the found the same to be true, she was delighted. I was also most impressed at just how hydrating and pleasant to use, my skin is quite dry so always good to add more layers of hydration.

    Would absolutely recommend this to anyone wanting to explore a BHA as this is very gentle but incredibly effective.

    I had acne and black spots since I was 9. A year ago I introduced this product on my korean routine beauty, and ITS SIMPLY MAGIC. At first, I dindn't noticed any change, but progressively, you will note that you have less and less blackspots. Now, one year later, it's the third time I'm buying this product. No more to say. It worths every single penny.

    Perfect for blackheads!
    September 10, 2018
    Though it does leave my skin sticky, I do recommend this at night only! My skin is combination oily on the T-Zone. Blackheads a lot on the nose! This does the most amazing job for my nose. I wear a lot of make up and the primers tend to clog up the pores therefore blackheads do form. This does it job to treat it !!!! Love it
