Third bottle

I've been using this serum for the past year. I have acne prone skin and this serum has been a staple in my routine. Whenever I get a blemish, depending on the size the serum can either make it go away completely or just look less angry. This serum has also helped with my post-inflammatory hyperpigmentation, and it is super gentle, I can use it even when I overdo it with chemical exfoliants. Overall amazing. This serum is so underrated.

I've started using this for about a month and I'm honestly a bit confused with this one; I use it as a spot treatment on my blemishes but I feel I see no difference on them. The only thing that I like about this product is that it helped with my pores a bit. I think I'll give it one more chance and see if it really works or not


I have used a lot of products for my hormonal acne. At 27 years old, and after several treatments like roaccutane which had no effect on my skin, the AC collection from COSRX really worked miracles. I redeem and I will redeem as many times as I need to.
However, I advise to alternate the AC collection with other COSRX products, for example I use the entire AC collection (intensive) in the evening, and in the morning I use AC sensitive + a more moisturizing range of COSRX + the cleanser low ph.
