Ordered over 2 weeks ago haven't recieved the product


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.
Sorry for my English, I am French.


I finished this bottle in a little over a month. After three weeks I saw improvement in my skin texture and my face felt brighter and smooth. However it didn't really impact my dark marks at all and I wear sunscreen every day. It's not the strongest formula but I think it's a good start if you want to try a product with niacinamide.


The cleanser itself has a very creamy texture and a strong scent which I was a bit concerned. As for my night skincare routine, I just squeeze a little bit of the product on my hands after wetting my face, then gently massage avoiding the area near my eyes for 1-2 minutes. As I massage it on my face thoroughly, I noticed the scent was not as strong and began to fade out as it turns to foam.

After I rinse with water, my skin felt softer and smoother. Although I was concerned about its strong scent, my face did not feel tight or irritated. In comparison with other cleansing foams designed for acne prone/sensitive skin that I have tried in the past, this cleansing foam does not make your skin feel dry and I actually felt more moisturized!
