“What exactly does this new product do?” This is normally what a sane person would ask first before buying something for the first time. But I’m not sane, I guess. I just heard that Cosrx was launching a new product, and I was like, “Cosrx?? New product?? Take my money!” Yes, we skincare junkies are crazy like that! ๐Ÿ˜‚

I eventually received my very own Cosrx Two in One Poreless Power Liquid in the mail about three weeks ago. I ordered it on BeautyMNL just a minute or two after midnight on the day of its launch on April 7, 2018. It went out of stock in less than three hours (I told you we’re crazy!) It was only then when I decided to do a bit of research on this new product and find out what exactly it does.


What It Does

So why is it called “Two in One”? The short answer can be found on the bottle itself: it contains (1) BHA – to help clean the pores, and (2) Tannin – to help tighten them. Just don’t look for the word “Tannin” on the ingredient list because you won’t find it there. It turns out Tannins are actually plant polyphenols commonly found in the bark of trees, leaves, stems, etc., functioning as their protective agents against bacteria, fungi, and even ultraviolet radiation. In the case of this Cosrx “Power Liquid”, the Tannins are found in the Salix Alba (Willow) Bark Water, which is what you will find on the ingredient list, instead.

In fact, the Cosrx Two in One Poreless Power Liquid contains 88% Willow Bark Water. Wow. That is A LOT. Really gotta love Cosrx for always giving us the good stuff, not fillers! And what is this Willow Bark Water good for, you might ask? Well, let’s go back to one of its components– Tannin. Just as Tannins offer so much protective goodness for trees and plants, they also do that for our skin, plus more.ย Aside from being potent antioxidants, Tannins are also natural astringents, meaning they have the ability to contract body tissues (i.e., tighten pores!). Its anti-bacterial and anti-inflammatory properties also help heal pimples and prevent new ones from appearing.

Meanwhile, the BHA in this product have two sources. BHA, short of Beta Hydroxy Acid, is also naturally found in Willow Bark Water, and at the same time Cosrx added 0.1% Betaine salicylate, which is its main active ingredient. BHAs are oil-soluble and they clean the pores by penetrating deep into them and removing oil and other debris. So, you can say goodbye to clogged pores, which is one of the main causes of acne.

What’s noteworthy about the BHA in this product, though, is its very low concentration, which I think makes it perfect for those who are sensitive to higher concentrations of BHA, or are just starting out with chemical exfoliation. I’m a huge fan of Cosrx’s One Step Original Clear Pad, and that one also has Willow Bark Water as its number one ingredient, plus 1% Betaine salicylate. I posted about it before on my Instagram, and while many agreed that it was also their holy grail, there were a few who said they could not use it as they seemed sensitive to Betaine salicylate. I am glad that there is now a milder BHA product I can recommend to these friends of mine, because I feel like if you have oily and acne-prone skin like me and you are still not using BHA, you are totally missing out!

Aside from this, the low concentration of BHA in this Cosrx Power Liquid makes it suitable for using it with other BHA products, like the Cosrx One Step Original Clear Pad, or even the Cosrx BHA Blackhead Power Liquid, which contains 4% Betaine salicylate.



I stopped using my Cosrx Original Step Clear Pad while I was using this Two in One Poreless Power Liquid to check whether it can replace the Cosrx Pads and maintain the status of my skin. I only used it with the Cosrx Pads recently to check if it would make any difference. So here are my thoughts:

After two weeks of using the Cosrx Two in One Poreless Power Liquid, I noticed that my pores looked smaller, especially on and around my nose, where my pores are bigger than those on the rest of my face. Just like my Cosrx Pads, it was able to help heal my existing bumps and prevent new ones from popping out. My hormonal breakout was not so bad and it went by quickly. Its oil-controlling action was also satisfactory. Blackheads are not really my problem, so I can’t tell how well this works on them. However, in the past two days, I tried using this with my Cosrx Pads, and I have to say the results looked better with my Cosrx Pads. Whenever I use my Cosrx Pads, there is that instant brightening effect, which is most likely due to the deep exfoliation happening. So I am thinking, this Cosrx Two in One Poreless Power Liquid is probably good for those who have sensitivity to higher concentrations of BHA or are looking for a milder BHA product, but if you’ve been using higher concentrations of BHA in your routine, you might find this Power Liquid too weak.


How I Use It:

1. Double cleanse. Pat skin dry.
2. Apply the Cosrx Two in One Poreless Power Liquid on the face with my bare hands. Two pumps are enough for me. I tried using it with a cotton pad and I ended up needing 5 pumps. It’s not cost-effective that way.
3. Wait 15 minutes. I just copied this from others because this is how they do it ๐Ÿ˜… But sometimes I just wait for it to be completely absorbed and then I move on to my next steps. It just depends on my mood, really. But I have read that Betaine salicylate provides time released exfoliation, meaning it exfoliates the skin long after the product is removed and evaporated ( So theoretically, waiting for a while is going to maximize its exfoliating benefits.
4. Use a hydrating toner. I always make sure to use hydrating products after exfoliation to prevent any dryness.
5. Continue with the rest of the skincare routine.



-Low Betaine salicylate concentration makes it gentle enough for people who want to incorporate BHAs in their routine but are sensitive to higher concentrations of the ingredient.
-Feels cool on the face, as it has a faint menthol effect; quickly absorbed; doesn’t leave a sticky residue.
-Delivers on its promise of cleaning and tightening pores
-Controls oil
-Helps heal existing breakouts and prevents new ones, too.

-Might be too weak for people who are used to higher concentrations of Betaine salicylate.



I belong to the group that has been using higher concentrations of Betaine salicylate, so I feel like I can’t go lower than 1% now. So I will just enjoy using this Cosrx Two in One Poreless Power Liquid with my Cosrx Pads while it lasts โค๏ธ
