"Every time that my husband and I are intimate since I’ve had the treatment, it has increased the pleasure and the satisfaction. We didn’t have a problem before but he’s like, “yeah, I noticed the difference”. It is a life changer. It has definitely given me more confidence."

"When I found out about the Emsculpt-Neo, I found out it combined all of those —it was able to melt away the fat and it tone my muscles, all combined in a half hour treatment and I did that 4 times and it combined everything and it was amazing. I feel amazing! I feel like a new me."

"I couldn’t jump rope, I couldn’t do double leg jump. It started there, and it just kind of progressively got worse —sneezing, jumping rope. I can now do them with a lot more confidence than I could before. It’s freeing, very freeing to be able to just do whatever you want to again. I’m 53, and I’m not feeling 53. "
