This product worked wonders for my skin.
It was a bumpy ride at first though.
I started incorporating retinol into my nighttime skincare routine last July 2020.
From July until first week of September 2020, I experienced purging! Pimples were endlessly growing on my temples (where I usually have breakouts). They never seemed to go away.
However, when September came, they started to disappear and I observed that my skin started to look better!
Starting October 2020, I use it 4 times a week. When I was just starting out, I used it 2 times a week. 
Now I rarely get breakouts and my pores have become "smaller" in apperance. 
Give it time to work! It's not a magic potion that will work overnight or just after a few weeks. 
Retinol works wonders!
I have been using it for a year now *I upgraded to 1% after 6 months *

Nothing! Except that it is a bit pricey for a toner.

Easily absorbed by the skin, very mild yet effective. Its texture is watery, which I love. Definitely alcohol-free too! Use it while skin is damp!

Takes a few minutes to absorb, and the smell might not be to everyone's liking.

Recently started incorporating niacinamide again into my AM routine (after an bad experience with the TO one), and I have no regrets picking this serum! It's effective and affordable! Worth trying. This was more effective than the TO niacinamide which I tried in 2018. 

None! Sadly, COSRX discontinued this product; I hope they sell this again 🙏 

Super amazing product. I wake up with fresh looking skin upon waking up. Seals in moisture too! 

It&#39;s a bit drying so if you have dry skin, do not use it every day.

My holy grail anti-acne facial wash!
It&#39;s super effective at killing active acne and acne that&#39;s just about to sprout up.
If you look at the photos I uploaded in this review, it was able to kill that amount of acne in less than a week of using it. (This acne was due to my retinol purging.)
