The Vampire Facial is a procedure that combines micro needling with application of topical PRP. The actual protocol and the results vary greatly depending on who is doing it. There are many different brands of micro needing pens and different kits to prepare the PRP. Practices using the high quality professional pens and using PRP kits that yield high quality platelets will get significantly better results. In our practice, we like to inject the PRP as well as put it on topically and we get phenomenal results. When you talk about "stem cell," be very careful. Most likely, the "stem cell" treatment is not really stem cells. There are various sources of regenerative cells from bone marrow, fat, amniotic fluid, amniotic membrane, umbilical cord blood, umbilical cord tissue and exosomes. These have all been referred to as "stem cells." Some of these products will have live cells in them with stem cell like properties, but the FDA does not allow us to call them "stem cells." In fact, marketing these products as "stem cells" is considered fraud. This is not to say that they don't work. These biologicals can have some very powerful regenerative properties even stronger than PRP but they are very costly. Unless you have money to burn, I would not recommend smearing these very expensive products on your face after a micro needling. Before spending your money on a "stem cell facial", I would recommend finding a reputable practice that is properly trained in the Vampire Facial procedure. Go to the official vampirefacial.com web site to look up the provider to make sure they are certified to do the treatment and get some great results, then you might want to step it up with some quality biologics.
