Which is more effective: Profhilo vs. PRP?

Prp is more potent at stimulating collagen regeneration, which in the end is going to give you the most long lasting result. The most important thing to ensure is that the PRP is actually Platelet RICH Plasma, because most Med spas use knock off PRP kits that don’t concentrate the platelets, which do not have any effect at all. In addition, a dermal pen is ok for applying PRP over tougher to treat areas and most Med spas that have nurses doing this procedure only use the dermal pen. The ideal application of PRP should be done as a combination of injections (into wrinkles, over cheek bone, under the eyes or wherever this is needed) and either Dermal Pen or even better using a laser like Halo to create channels in the skin and applying the PRP topically afterward. 

I don't believe that I have seen any reliable study that compares elastin- injectable hyaluronic acid treatment Profhilo and PRP.
