    Works really well
    July 4, 2017
    Could see the difference in use already after one week of use on the whiteheads on my chin. Blackheads are smaller, skin with sebum deep underneath the surface appears to be more smoothed out. I use it every other day, seems to be a bit strong for everyday use.

    I started with acids for a year ago, Paulas Choice BHA products only. After reading great review cosrx I bought both their BHA and this one. I think the BHA has done most of the job, since it was blackheads I wanted to get rid of. I use this one once a week, just after cleansing. I can really recommend to use a pore mimiaing/clay mask after about 20min after putting on the AHA.

    I've only used this a couple of times - I've alternated with the BHA power essence to let my skin adjust - but I can already see a huge difference. My blackheads are smaller (even before using the BHA), not noticed a change in my whiteheads yet, but there is a HUGE change in the smoothness of my skin, it's like my pores have been airbrushed. Recommend using this after toner and then waiting like they say on the bottle - it definitely makes a difference - it then has a chance to penetrate the skin without being diluted by further skincare steps. Oh and also I have a couple of friends who have used it consistently for a while - and they also can't live without it.

    feels comfortable on acne prone skin and it helps!
    September 4, 2017
    The product sits comfortably on skin (not too thick and spreads out easily).I have acne prone skin, with a lot of scarring. I've been using this for 3 weeks and I can see improvements! It doesn't burn my skin (like other products have) and does not feel sticky. Will repurchase!

    My skin is better than ever!
    April 20, 2019
    After using this, I swear my skin has never felt so smooth and even textured. Of course this doesn't prevent the odd hormonal/diet-induced breakouts, but my skin's overall appearance has improved decently. But ditch those cotton pads, people. Waste of money and bad for the environment. Put a tiny pump into your palm and pat it into your face with your fingers. A little goes a long way!

    Trusted toner/essence
    February 26, 2019
    Never disappointed me, from 1st use 5 years ago to this day. It progressively clears the skin and even your skintone without being harsh on the skin. They recommend to use it only at night but with a good spf I have been able to wear by day - and under makeup. It's not drying but if you have combination skin I recommend to be more generous with your skin in that aspect.

    3rd bottle!!!
    January 20, 2019
    I just purchased my third bottle. I remember going a couple weeks without this and my skin felt so bad without it. I felt like it made my skin soft or something and I felt like this extra step helped exfoliate my skin a little more since it contains aha. I wish they’d make the bottles a little bigger. I can only access cosrx products online since there are rarely any stores in my city that sell Kbeauty products without ripping off the price. it sucks to have to put in an order every couple months but it’s worth it
    October 3, 2018
    I've been using this for about 2-3 weeks now and i can say that I've been getting less frequent breakouts especially during that time of the month where my skin goes crazy. It works better than witch hazel, that only did the bare minimum. Some of my whiteheads have been going away and some just seem too stubborn right now. I've experienced some purging like some reviews have said but I suppose that's a good thing as I've read when I looked up on this product. Those breakouts from purging went away after a couple of days with no scarring. I do wish the bottle was a little bigger because I'm almost half way through since I do use it every night and sometimes in the morning. I'd purchase this again though!

    After struggling with physical exfoliants breaking me out for so long, this is my saving grace. I started off using this once a week, slowly increasing how frequently I used it as time went on and had no problem with irritation, even with my skin being incredibly sensitive. The texture of my skin has been greatly improved so far, as well as my acne and marks left from old acne have both slowly started to fade. I'm looking forward to seeing more improvements with time!

    I've been using this product for a few months and I can say there's definitely been a change in my skin texture. My skin is the smoothest it's ever been. You start to see results about 2 weeks in, your skin needs to purge. For me I had some intense dry patches around my mouth, nose and forehead. A few whiteheads but nothing dramatic. I really recommend this if you want a smooth skin texture. (note: if you also want to get rid of blackheads, buy the bha treatment as well. This one doesn't eliminate blackheads)

    Great product
    February 24, 2018
    I love this product! This was my first chemical exfoliant and since I've bought quite a few stronger product. This is still my holy trail- it's gentle and not too drying, and it's cleared up my acne to leave smooth skin. I started off using this a few times a week but have built up to using it every day. It's also effective as a spot treatment for the occasional pimple, and clears it up much faster. Will definitely be repurchasing!
  • Anastasia
    Highly recommend
    December 9, 2017
    I use it once a week. I have white heads, blackheads and the structure of my skin is not the best. After using AHA 7%(by the way, the persantage is very good), I can't stop touching my face. It's so smoothe and pleasant to touch. If u have post acne scarring, it may help u with fading it. I will purchase it again after finish. However, it seems like it will last forever haha
  • Silvia Giagoni
