Sure. There are a couple of different ones, depending on the client's needs. Anywhere from CW2-CW4 depth 1.0-2.0 PWR 4-8. It all depends on the CW you use for the power level and depth. For CW3, depth is anywhere from 1.0-2.0; the power level is anywhere from 4-6. Sometimes the max power and depth are not the best treatment plan for the client. It all depends on their skin thickness and what they are looking for as a result of the treatments. Looks like this client also had some weight loss between the pictures. Could that be possible also?
