I had SculpSure done 4 weeks ago and I'm doing a second treatment next week.

I generally space treatments out by 6 weeks in order to ensure the maximal effect has been obtained from the prior treatment. This ensures that I am not dealing with a "moving target," so to speak. The patient has stabilized and I can be confident about the starting point for treatment #2.As always, discuss your concerns with a board certified plastic surgeon (ABPS).

There is no optimal time to wait in between SculpSure treatments to the same area, but I would recommend waiting at least 4 weeks in between sessions.  There is no harm waiting a longer period of time though.  It should be fine to have your second treatment next week (which would be at least 4 weeks after your first session).
