It's Probably Useful for a Beautician
The product works as it described, both for releasing mist and examining the skin moisture level.  I used the mist to moisten my face hoping it could soften my dry fine lines but it didn't. The moisture from the mist didn't last, 3 minutes later my face's moisture level dropped back to a "sad face" level. This product is probably useful for a beautician who wants to do some product demonstration in front of the clients, but it has little use for me.
