Non-Invasive Lipo - real or fake?

I come at this question from a surgeon's perspective, anything that does not actually remove fat can only be a gamble in the best case scenario. Nothing wrong with surgery done in the proper setting!

In our experience, the minimal benefic associated with most forms of non-invasive fat removal do not justify their cost.  In the long-term, the "fat reduction" tends to be temporary and the results are not long-lasting.
However, in the right hands, lipo can be:
1- Very minimally invasive; there is only local anesthesia
2- Permanent.  Or at least much much longer lasting
3- Almost equally safe. 
4- A one-time treatment, rather than a series of sessions spread over weeks.
Ultimately, you want to see an experienced practitioner who is able to assess you and provide you with the best advice.  Make sure you see plenty of before and after photos.
Hope that helps.
