I've been using this 7-in-1 Face & Neck LED Sculpting Device for a few weeks now and the dolphin-tail shape really does hug my jawline and neck well. The 7 LED modes and EMS microcurrent give a nice firming feeling, and the thermal heat is soothing. Sessions take about 6 to 10 minutes, which fits easily into my routine, and my serums seem to absorb better. It's not a miracle worker, but it's a solid at-home option for smoothing neck rings and defining the jawline.
