The major problem here is that while there are a many procedures used to reduce cellulite, none produce lasting results and most are very unpredictable in their effectiveness.
Smartlipo uses a workhorse laser (Neodynium/YAG) at high frequencies to directly disrupt fat cells. (The fiberoptic probe is placed via a small incision directly into the fat.) It is often used in conjuction with traditional liposuction and reportedly helps the skin shrink. It is not designed or promoted for cellulite treatment.
Liposelect is a form of direct ultrasonic liposuction. Again, its use is for liposuction purposes and is not often used for cellulite. Other alternatives include repeated treatments with roller therapy over the affected areas with either vacuum suction (Endermology treatment) or in associated with low level radiofrequency therapy (Velasmooth laser system). If you have very high expectations for treatment results, it is likely that you will be disappointed. Consistent predictable long term results are not available yet.
