    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!!

    This BHA is legendary for good reason - I'm able to use this 3-4 times a week without any irritation. I'm oily-combination, with blackheads on my nose. Since I started using this, and I'm now on my 4th bottle, my oiliness has become so much more controlled. The blackheads and pores on my nose have completely disappeared - it's an unbelievable difference, but it did take consistent use to get such great effects. I 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.)

    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.

    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.

    Best BHA Exfoliant made
    April 29, 2020
    After trying many other brands since buying this I can conclude this is the best. The ingredient list is the best and cleanest. This price is probably the best you can find. Use this code for a discount ! 552ZZY
    BHA Exfoliant for every skin type or condition
    August 25, 2018
    This is so gentle and non irritating. It doesn't leave your face overly dry or contain any harmful ingredients. This is also Malassezia safe which is amazing since most skin care products at least have glycerin. Cosrx definitely nailed it on this one. Contains Willow bark instead of water as first ingredient. Also Niacinamide & Sodium Hyaluronate ! Oof!

    It works!
    July 21, 2020
    After having tried the AHA/BHA toner, I felt like I needed something a bit more strong and boy did I find it. I use it every other night have have noticed my blackheads almost disappearing and even my pores becoming much smaller and tighter; something I never thought would happen. I’ve struggled with this issue for years, especially around my nose area and this has really done the trick for me. It’s still gentle enough (though, if you use it in the morning: please, PLEASE use spf/sunscreen) for my skin, but heavier than the aha/bha toner. A must-have!

    So far so good
    August 30, 2018
    I've been using this for about 2 weeks. I have (South Asian) oily, acne prone skin and I persistently get hair removal on my face. My skin is already used to chemical exfoliators (I started with mandelic acid, then 10% lactic acid, both from a different brand) but I didn't like either. I get stubborn blackheads and clogged pores around my chin and inner cheeks and this is reducing the rate at which they appear for me - not completely gone yet which is understandable for 2 weeks. As for my whole face, it's become softer and 'plump' to the touch, hasn't really positively or negatively affected random acne etc. I also used to get a lot of post-hair-removal pimples or clogged pores and those have reduced too. Ingredients like niacinamide really caught my attention because that's also a key ingredient for fading PIH (hyperpigmentation)! A good alternative to basic direct acids, really nice formula.

    HG, great for cystic acne
    August 26, 2018
    I don't use this for blackheads but instead for angry red cystic acne that have not surfaced. It really helps to bring the pimple to a head.

    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.

    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
    March 4, 2019
    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.
