I am an esthetician, and I use NuFace in my treatment room. Esthetician's have been using mircocurrent for years, but I like the NuFace because I am not bogged down in wires ( as opposed to other microcurrent machines). It also helps acne, which is great since I get a lot of clients who are concerned with aging and acne. Overall I am very happy with this device and my clients (and myself) love the results as well!
