I feel like my skin tone has improved a little since I started using it.
I like that this serum has a thick texture but doesn't interfere with what I use next! The scent is unique, so people's tastes may differ... I also like that it can be used both morning and night. I use it at night, and when I wake up in the morning, my skin tone seems to have improved. I'm sure it has an immediate effect. I have sensitive skin, but I've been able to use it without any problems.
I was attracted to the tagline "transparent skin" and bought it. My skin instantly became brighter within a few days and I could really feel the effects. After watching Tomori Arata's YouTube videos, I started using it in combination with HAKU. Some people have said that the scent is unique, but I didn't find it that bothersome, and I like the feel of it, so I keep buying it.

This is my third repurchase. I love how it leaves my skin feeling moisturized and smooth, and my acne and other skin problems are noticeably reduced. The scent has been controversial, but I love it because it's floral, like the scents you'd find in a department store.
