Will herpes stop you from getting liposuction?

As long as your herpes is inactive (i.e., you are not currently having a flare), liposuction is not contraindicated. If you are not already taking an antiviral such as Valtrex™ or Famvir™, you may want to do so before your liposuction to avoid a flare before the procedure and/or during your recovery period. You may also want to consider noninvasive fat-elimination techniques, such as Vanquish, CoolSculpting and ThermiTight. Please consult a board-certified dermatologist who can offer you a number of options to get the best body-contouring outcome … and do mention your condition during your meeting.

If the herpes breakout involves areas near the region where you plan to have liposuction done, then it might affect whether or not it's safe.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search. 

It will not affect you to do liposuction as long as you do not have an active episode. If you do is best to post pone the procedure.
