If I have TempSure skin tightening on my entire face, how long before I can get PRP injections?

Dear Sun_Dahlia,Tempsure Envi will create some lite swelling, that will be reduced in a few days. However, if you want to see the complete result of this treatment before doing the injections, you would need to get your full treatment of tempsure, 3-5 treatments, 4 weeks apart.If you already decided you want to have Tempsure and PRP injections, I would wait a week after Tempsure, before getting PRP, or Botox or any other treatment.Be carefull about getting the injections first and then tempsure. With Botox, you need to wait longer , at least two weeks, before you receive a Tempsure treatment.

Hi Sun_Dahlia, 
As with any sort of procedure, take caution. It is recommended that you do TempSure first then wait two weeks before having botox, for example.  So, PRP, being an injection (although not toxic like Botox), I would recommend waiting a month to allow the full effects of the TempSure to manifest, then after the PRP wait 2 weeks to do the TempSure again.  I would make the same suggestion if you're talking about doing a vampire facial, microneedling with prp.
However, it's safe to do it two weeks after your TempSure treatment according to the manufacturer.

Dear Sun_Dahlia,
Thank you for the question. After treatment with Tempsure Envi on your face there will be some swelling which will resolve in up to 10 days. I'll recommand to wait 10-14 days before you have another treatment on your face like PRP.
