I have very dry skin, so it felt refreshing and did provide some moisture, but it was difficult to achieve the desired moisturizing effect. (I like the moisturizing feeling of MatsuKiyo's Treatment Serum, and this one seemed to have better ingredients, so I thought I would replace it with the Treatment Serum, but it turned out to be a completely different product.) However, since the ingredients are said to be good, I would like to use it on my neck and other areas as well.
Apparently this is a limited edition product. It's too good to be called a limited edition! A great ally for dry skin! I feel like my skin is more hydrated and it feels great.
I was interested in the Kansou-san series, and when I saw that it came with a cute character handkerchief, I bought it. It's convenient when you want to do something quick after applying lotion. It's moisturizing and doesn't irritate. I'm not sure about the whitening effect yet, but I'd like to continue using it for a while.
