I won this as a gift. It has a thick texture and the alcohol scent is weaker than other products. I use it around my mouth, which tends to dry out easily, and it's very moisturizing without causing any flaking, which is great! It's not too expensive for a serum, so I also use it on my neck. I wanted to use a serum on my neck, but I didn't want it to be too expensive, so I plan to buy another one once I've finished using it.
It has a nice scent. It has a typical gel texture. It's a large size, so I use it on my body. It's perfect for moisturizing in the winter. I think people who don't like sweet floral scents will love it.
I've been using it for years! I have the entire Kikumasamune set, from lotion to cream! My skin feels so firm on days when I use it and days when I don't! In the winter, I use so much that it disappears in no time! It's not sticky and blends in easily \(^o^)/
I regularly purchase this product because it leaves my skin feeling moisturized. Regarding the amount to use, the package says to take two or three pumps after applying lotion and apply it to your entire face, but I personally find that to be too much. It's very hydrating and spreads easily, so one pump is enough to cover your entire face and neck. Regarding the scent, I think it's fine for people who like sake, but if you don't like the smell of alcohol or fragrances, I recommend trying the tester first.
I've only been using it for about a week. My skin has suddenly started peeling, breaking out in acne, and wrinkles around my eyes. Is it age or dryness? My dryness has been really bad this year. I use the same lotions and creams, so I was looking for a cheaper serum that offers moisturizing benefits plus some whitening or wrinkle prevention, and I bought this. The alcohol smell was a bit stronger than I expected, which I don't like. But it's only a bit strong for the first 10 seconds or so, so I hold my breath while applying it. I've only just started using it, and I'm using a cream and eye cream at the same time, but the dryness and wrinkles around my eyes have been significantly reduced. It doesn't leave my skin feeling moisturized until the afternoon, but it's had the desired effect! One pump is a lot, so I apply half a pump morning and night.
