I've been using this Neck & Face Lifting LED Therapy Device for a few weeks now, usually after applying my serum. The dolphin mouth shape is genuinely nice for massaging around tired eyes, and the vibration feels soothing without being too harsh. I mainly use it on my neck for the lifting effect, and while my double chin hasn't vanished, my skin does look a bit firmer and less puffy in the mornings. The three color modes are easy to switch between. It's a gentle addition to my routine rather than a miracle worker, but I'm happy with it so far.
