It’s no secret that Korean skincare techniques are a lot different from the rest of the world, and one of those differences is the way of exfoliation. I’ve often talked about the goodness of chemical exfoliators in my blog and have previously reviewed an exfoliator that works both as a chemical and physical exfoliator. Today I’ll be reviewing my first chemical exfoliator that’s highly raved from other K-Beauty bloggers.

But first, I’ll like to explain the differences between chemical exfoliators and the physical ones.

Physical exfoliators, AKA scrubs are widely used throughout the world but I personally feel they can be harsh, even the ones that contain the tiniest micro beads. And the worst thing you can put on your face is walnut scrubs, using walnut scrubs on your face is like treating your skin as a dirty frying pan. And then, they don’t even properly do the one job they are meant to do, exfoliate. Physical exfoliators only remove the dead skin that’s on the surface, while chemical exfoliators go deep within the pores and are oil-soluble, so they dissolve any oil that’s clogging your pores and they also contains anti-bacterial agent. They are like the holy grail for acne prone and sensitive skin (since they are mild).

COSRX BHA Blackhead Power Liquid

Like I said, I’ve previously mentioned I’ve used an exfoliator that works both as a physical exfoliator and a chemical exfoliator but the CORSX BHA Blackhead Power Liquid is the first chemical exfoliator I’ve ever tried (well I tried chemical exfoliating pads from the same brand) so I cannot preach much, but I’ll simply share my experience.

Cosrx BHA Blackhead Power Liquid reduces blackheads and excess sebum while hydrating skin. Formulated with betaine salicylate to fight acne-causing bacteria, this lightweight anti-acne serum eliminates and prevents stubborn pore blockages. Made with a base of white willow bark water, this highly effective treatment leaves skin clear, bright, and blackhead-free.


After cleansing and toning, dispense 1 to 2 pumps onto fingertips and apply it to the areas of the face where blackheads occur. Wait atleast 20-30 minutes before applying your next skincare item


Salix Alba (Willow) Bark Water, Butylene Glycol, Betaine Salicylate, Niacinamide, 1,2-Hexanediol, Arginine, Panthenol, Sodium Hyaluronate, Xanthan Gum, Ethyl Hexanediol.

My CosDNA analysis came out pretty clear with only Butylene Glycol raising one flag which is present in almost all beauty products anyway.

My experience:

The bottle says that you can use it almost every day but if you are using it for the first time, start with once a week application and let your skin accommodate with it first. So I never had much blackheads and pore issues but in the last couple of years I used some pore strips that stretched out my pores resulting in a more blackheads near my nose area. On the other hand I got a few open pores after suffering from the skin infection this year. So I currently have minor blackheads issue and a minor pore issue, also I’m not suffering from any breakout in recent days (touchwood), which is why I haven’t frequented my usage over thrice a week yet, in fact I’m limiting my usage to twice a week and I’m quite satisfied.

The first time I applied this BHA power liquid was while following a pore shrinking method that I shared in my blog few days back. The BHA is the first step in that routine and you are supposed to keep it on for 20 minutes and then layer it with a clay mask. The next day my hyper sensitive skin, especially the area above my lip got swelled up a little and I realized that I used more than 2 pumps. But my skin did feel squeaky clean.

A week later, I came back to this bottle and followed the pore shrinking method once again, this time without any hint of irritation. My skin had indeed accommodated with it. I followed the method one more time a week later and then frequented to twice a week. My blackheads have visibly reduced and the acne marks that my skin infection left behind, completely disappeared. Since I use it only twice a week, I only apply it while following the pore shrinking method but I did try out the usual way once: double cleansing-BHA(20 minutes wait)-toning-essence-sheet mask-night cream-eye cream and it worked out pretty well.

I’m immensely satisfied with the results and I don’t think I’m going back to manual exfoliation anytime soon. I’m comfortable with twice a week usage as I’m not facing any skin issues right now (touchwood) but for people who are suffering from acne, clogged pores and blackheads, you may use it as frequently as every day. I’ll suggest following the pore shrinking method once a week, and apply it the usual way the rest of the week. And for normal skin beauties, you can use it 2-3 times a week.

    1. Unfortunately I haven’t used the mentioned products yet, but I’m a big time fan of cosrx products, so I’ll definitely recommend. Also what’s your skin type?

    2. I hv oily skin,with few huge pores on cheeks,and often get lots of blackheads….i have very sensitive and thin skin,wen its good it looks awesome but when its bad it looks terribly dull.and i am searching for good korean skincare product range,n eyeing to buy sm from wud be really helpful if u cn suggest me some stuffs in your knowledge.

    3. Since you have sensitive skin I will recommend to introduce one new product every 2 weeks. You can try cosrx good morning low pH cleanser, cosrx bha blackhead power liquid, klairs supple preparation toner, Mizon snail repair gel, klairs soothing cream.

    4. Thnk u so much dear..i was eyeing on almost.

    5. What a co-incidence! I’ve recently done a haul from Haba-Lado which is yet to be delivered. Meanwhile my guest author Anwesha also did a haul from Haba Lado and her reviews are in progress. What if I tell you that the brightening toner is included in my haul? 😉

    6. Hehehe….we hv so many common choices.
      It was hell out of time taken to search and understand hada labo,coz as its japanese i had a tough time to know which product to buy,atlast i wen for shirojyun series.God they have so many options.can u tell me from where did u buy,i hv shortlisted yesstyle for it.They hv the lowest price i guess.And ya cosrx bha liquid is out of stock almost everywhere on indian websites,even on beautybarn,i was planning to buy low ph cleanser and liquid both together,as i cnt wait to start these,but unfortunately hv to wait even if i order from international sites as therr are holidays in korea so everything is will buy low ph cleanser alone for now.

    7. I choose EMS, and my guest writer Anwesha chose the Standard one, but her shipping cost was around 550rs anyway
