I have dermatillomania, and have struggled with it for over a decade now. Because of this, I have a ton of scar tissue that caused years-old clogged pores, and skin that wouldn't exfoliate properly no matter what I tried. I finally tried an AHA after using a BHA + Retinol routine for a few months with minimal results, and I nearly cried--my pores are finally recovering! My skin was immediately smoother, I'm finally purging properly, and I've already noticed changes in texture. This is why I use cosrx!! Y'all always come thru

I definitely have been getting less spots on my face since using this in tandem with the BHA power liquid. My skin texture has also been improving and it did not take long after my first use to see improvement. I didn't purge much using this but I think that is because I had recently purged after using the AHA BHA Vitamin C toner. It also has a nice and light texture and settles into the skin relatively quickly. I will definitely be buying this again!

I was cautious/used 2x a week as directed (it has a little sting) but that was exactly what my skin needed to get rid of my whiteheads. Not gonna lie, I use it everyday and thats when I noticed a HUGE difference (I don't recommend increasing use unless you don't see any change and want to gradually increase to what feels right for you) 100% would buy again but I don't think I will need to! My whitehead worries are nearly gone and I still have lots of product left.
If you're wondering I put 2 drops in my hands and tap it into my problem areas. :)

This has really helped the texture of my skin. It's making it brighter, less congested, makes my pores less noticeable.

So far I have not seen much of a difference, but I like texture and have high hopes it will work with time
