Can subdermal J-Plasma be done twice?

Yes this procedure can be done more than once, and often can be combined wtih VASER or even ThermiRF to get better outcomes. WE often add threads at the same time as well -- instalift.  Please see an expert.  Best, Dr. Emer.

Why should one repeat a procedure that has failed to deliver the desired result?  Procedures exist only in service of results.  If an intervention does not accomplish the change for which it is indicated, that procedure becomes a cost, risk, and recovery time liability without offering any asset or benefit in exchange.  The answer to your question seems self evident, i.e., even if you “could” safely repeat the procedure, why would you?
