How far apart should SculpSure to the abs/flanks and Velashape 3 to the front and back of thighs be separated to be done safely?

Thank you for your question. Each treated area (i.e. abdomen or flanks) takes only 25 minutes per treatment. SculpSure is revolutionary for its non-surgical, non-invasive, treatment process where patients can expect to see fat reduction in treated areas in aobut 6-12 weeks after just one treatment. I suggest that you move forward and consult with a board certified facial plastic surgeon.
Best wishes,

Since the areas of the abdomen and flanks that you had treated with SculpSure are different than the thighs that you are going to have treated with Velashape, I think you could space them apart at any time you wished.  They could potentially even be treated the same day.  One treatment should not affect the other.    

Consult with you surgeon or technician. Some surgeons will perform both on the same day. You just want to make sure that you was it 6 weeks between treatments. Best of luck.
