"MeSmooth's application head is made from 18K gold, suitable for sensitive skin, and really comfortable to use. I use the penetration mode every day. The best part of this device is its lifting mode with EMS technology, there's a slight tingling sensation so I know it's working. After using, I can feel my face is firmer. MeSmooth helps cleans my face better, makes my skin more radiant and reduces fine lines. I recommend everyone to try it!"
