I had a stretch mark removal tech cancel on me, so I reviewed her videos and realized that this is the device that she’s using – I looked up some videos on people using it on themselves & decided to save $400 for the appointment & just do this myself – I’m glad that I did. I open the box the very first day it the pain level is super low – just make sure to sanitize your skin and start out low with the levels & make sure to purchase a collagen serum to put on afterward- I’m very very excited for the good results to come!
