Hi there lovelies, long time no see. I have been testing quite a number of products the past few weeks, and since COSRX has been gaining quite a bit of attention recently, I decided to do a review focusing on this brand itself. Many followers on Instagram also asked for my opinions regarding COSRX products. Today I will share with you my opinions on the product that I have been tested for approximately 2 months now: COSRX AHA 7 Whitehead Power Liquid. Stay tuned for my future review for BHA Blackhead Power Liquid, and Advanced Snail 96 Mucin Power Essence.

Disclaimer: This blog is merely where I share my opinions about product that I have tried. I cannot guarantee what works for me will work for you. So please PATCH TEST all the products if you know you have sensitive skin, or stay away from those that has alcohol and strong fragrance if you cannot stand those.


My COSRX stash at the moment

Before we started, I have a confession: I am absolutely in love with COSRX as a brand. Their ingredients list is relatively short and pretty straight forwards. Products is fragrance free, paraben free and coloring free, which is a huge plus for sensitive and acne-prone skin like mine. After using their products for a while now, I am confident to say that my skin has been greatly strengthened and healing process happens much faster for the aftermath of my acne fighting, scars fade faster, skin texture is less bumpy and I am indeed a much happier girl 🙂 My goal is to finish the rest of my skincare and convert all my products to COSRX and COSRX only. Yup, I am absolutely in love. Now I shall share in details about the product that I have been tested.

Simple and clean packaging


Even though the product claims to have Apple Fruit Water as the first and start ingredients, I was so put off with the smell at first. The smell was so pungent and strong and definitely does not smell anything like apple. Overtime I get used to the smell a little bit, but I can’t help but stop inhaling whenever I apply this product all over my face.

How to use? (from COSRX)

1) Since this is a high concentrated formula, we recommend it to only be used in the evening. Spread lightly in areas where whiteheads and dead skin cells appear after using toner to clean skin texture.
2) Use clean hands or cotton pad to spread on the face to absorb by patting softly with fingertips.
3) If you feel severe stimulation or your purpose was just to remove whitehead and sebum, wash off after 4 to 5 minutes with lukewarm water.
4) Use essence and cream after the use of AHA 7 Whitehead Power Liquid. And do not forget to use sunscreen in the next morning.

5) AHA 7 Whitehead Power Liquid is high concentrated product. Please use a small amount on areas with whiteheads and dead skin cells. Begin with using only once a week, and after skin has adjusted, use 2 to 3 times a week to maintain clear skin without dead skin cells, sebum and whiteheads.
6) When you use AHA 7 Whitehead Power Liquid, do not use other exfoliating products on same day.
7) After the use of AHA 7 Whitehead Power Liquid, use serum or mask products to moisture your skin
When you utilize this product please avoid using any products that contains high level of AHA, BHA (include Betain Salicylate), Retinal, Vitamin C (Ascorbic Acid).

How I actually use this:

I did not want to mess with the caution, so I use this on alternate with the Blackhead Power Liquid, and notice great results. I normally use this after my toner step, when my skin is perfectly cleansed and balanced. After waiting for 20-30 mins, I move on with a hydrating essence/serum, followed by sheet mask, light gel cream and sleeping pack. It is important that other products following your acid treatment step are all hydrating to help sooth the skin after the treatment. 

Do note that you need to introduce this into your skincare very slowly. I recommend once a week first, then slowly increase the frequency after your skin get used to it


It is an extremely light-weight texture that is as runny as water. The liquid absorbed onto my skin with minimal efforts, a little bit of tapping with help it absorbs much faster.


This using in conjunction with the Blackhead Power Liquid improved my skin significantly over the past 2 months. I must say, my skin has never do so well for the longest time ever. All my acnes and pimples are in control, scars are fading quick and most importantly, those funny bumpy texture on my skin is gone. Now since I use this together with the Blackhead Power Liquid, it is hard to identify which problems is solved by which products, but I believe this controls stuffs that happen more on the surface of your skin.

    Thanks for your review I really love it ❤️ But I want to ask you this to make sure 🙂 I currently order 3 products : 1/klair vitamin c , 2/Cosrx aha 7 power liquid , 3/Cosrx bha power liquid. As you say that you use it alternately so I want to know that can I use it like this ? Ex: on Monday I use aha and Tuesday I use klair vitamin c and Wednesday bha. Is it okay to use it like?


    • glowingchronicle says:

      Yup it’s totally fine to use it like how you mentioned. For best effects, I normally one day use BHA to bring all the guns deep under skin out, AHA the next day to clear off the skin surface, and vitamin C the last day to brighten complexion 🙂
