I have read a lot of positive reviews on this product, so I wanted to try and this is my first time trying a sleep pack. It has a faint scent to it and it didn't bother me as much. I have sensitive senses, and this passed the scent test for me. The texture of it is slimy and gooey. The slimy texture stays that way until you wash it off. I can't imagine myself falling asleep with this without putting a towel on top of my pillow. I have only left this on my face for a few hours the most, but it does its job very well at moisturizing. I just bought the skin moisture checker from Japan recently, and this showed that my skin's moisture level went up significantly after using this product. The price is fair for the brand! I mean it is Shiseido after all. I got this jar for 38.99 USD on ebay from a seller in Japan. Lastly, this also DIDN'T break me out. I have sensitive combination skin that's prone to acne. They also provided the consumer with a free spatula to use.
Belulu works. This is probably considered to be a obsolete model in Japan, but it works. I recently saw that Phillips JUST launched a similar product and you can record your results through their FREE app. However, I am cool with this BELULU one. I have tested it on a few people and it seems pretty accurate.
