Is it safe to have the PRP Tru Vampire treatment after having Sculptra 6 months ago?

Both procedures are intended to increase collagen production resulting in more youthful looking skin 
I use Sculptra and combine with PRP and PRF so you should  have positive results 
recall Sculptra should continue to improve your collagen content and it likely still evolving so you might want to wait another six months unless you only had one round of sculptra and didn't get the response you expected

Sculptra works as a bio stimulator and the results can last for 12 to 18 months. The PRP injections improve the quality of the skin by bringing in various growth factors which then go on to produce the required improvements. Mechanisms of actions for both these treatment modalities are different and not counterproductive. Hence there is no reason why you can’t have both treatments at 6 months apart.
