Amazon カスタマー 4 I have been struggling with these tiny bumps on my skin which make it appear rough and uneven at places. I recently discovered that these are comedonal acne or the acne that could not completely surface and I didn’t know how I can encourage these to open up and disappear eventually. I read and watched about VC serums and tried Kiso VC 30 for the first time. It’s been a month exactly and I apply it daily twice after my sebum care serum and top it up later with moisturizer. So far I can see that the comedon acne are popping up (thankfully on my dry skin they are nothing but tiny dots which are hard to notice ) and I just ordered another bottle 2 days ago. It already arrived (so fast) and I am going to continue using for at least a few months I think. The vitamin c used in this is one of the most stable ones they say and I am so far happy with it.
