Added January 19, 2026. I saw a YouTube video by Kazunosuke that said rubbing the cotton pad too hard on the skin isn't good, so I stopped using it for a while. Then, I noticed that my blackheads seemed to have gotten noticeably darker... It also contains firming ingredients like witch hazel extract, so maybe I'll just use it for dabbing? --------------------------------------This is so good! I used the tester in the store on my bare face, and the cotton pad turned light brown, so I was skeptical and bought it, but it really did soften the dead skin cells, removing the roughness and leaving my skin smooth. I have a lot of blackheads and blackheads around my nose, and in just two days, they turned a beige color. I've been using the enzyme cleanser → this → lotion → whitening serum → cream for a few days, and my skin feels amazing! I tend to get clogged pores around my face, so I've been rubbing this with a cotton pad, but my face is still rough... I'm looking forward to trying it in the future. I'm also interested in trying the cleansing oil together! ----------------------------------------------------------- Update: October 17, 2025: I'm raising my rating. ★6 → 7. I'm almost out of one bottle. I was so curious that I ended up buying the ONE by KOSE oil cleanser and facial cleanser!!! I now use the oil cleanser, then the facial cleanser, then this, all of my cleansing products from KOSE. My skin... My pores, which used to be so rough and rough around my nose, jawline, and cheeks, are now so smooth and silky to the touch... It's so new to me, I sometimes touch my nose and glide my fingers over them, smiling with glee. It's amazing how much money I spent on a facial cleanser... If you're troubled by pore problems and severe blackheads, such as blackheads and clogged noses, I recommend giving this a try. Using this especially after washing my face softens my skin, and I can feel the dirt being removed. It also seems to help my next lotion soak in better, so I might not even need a serum to start with. I'm really glad I bought it
The blackheads on my nose are gone! I received this from a friend who accidentally bought multiple bottles. The first thing I do after my evening bath is wipe them off with a cotton pad, then my usual skincare routine. By the time I finished the bottle, I noticed that the blackheads on my nose that hadn't gone away no matter what I did had vanished. This is my fourth repurchase. It's a little pricey, but I think it's effective!
During the December 2025 Suzykirei sale, I purchased One by Kose cleanser and facial wash, which came with a trial size. I used it for about two weeks starting in January 2026. I used it in conjunction with FANCL cleanser, One by Kose facial wash and serum, and d Program lotion and night cream. The scent was a little strong. The texture was neither good nor bad. I feel like my skin irritation has decreased. I didn't notice much improvement in pore size or clarity, but I did feel like my skin became a little more radiant. I'd like to try the One by Kose cleanser and facial wash, but I don't think it will dramatically improve pore size or clarity, so I don't think I'll buy it again.
ONE BY KOSE Clear Peel Serum [Product Used] ONE BY KOSE Clear Peel Serum [Product Features] Eliminates blackheads and dead skin cells. A pore-clearing wipe-off serum that proactively tackles pore problems. This one product provides pore care, exfoliation, and moisturizing care, leading to smoother, less noticeable pores.
Since using this in the morning and evening after washing my face, my skin feels better and the dullness has lessened a bit. I can use it without any stinging, itching or redness. I have bought it many times. They also sell a small trial size, so I recommend trying that first.
