How It Works

An introduction to how the treatment works and what you can expect during your visit.

Amazing…I lost 33 inches and 2 sizes with just 15 treatments. I have more energy and have kept the inches off! It has truly changed my life. I recommend it to anyone that wants to feel better about his or herself. I love the way I look and feel!


I couldn’t get rid of my love handles. I have tried different diets and also exercise. Nothing was working. I decided to try Body Slim Spa. I was skeptical at first but it really worked. My abs were firmer and I was able to tighten my belt 2 notches.
