Selphyl. What is it? How does it work?

in a simplistic answers, Selphyl is a branded preparation system to prepare PRP which is derived from a small amount of your own blood. PRPor PRFM (which is PRP with an activator) is then injected in target areas to act similarly to a filler. PRP can be prepared via differed centrifuges and kits but be sure your doctor is using FDA approved PRP kits. 

Selphyl is a single spin tube preparation system for platelet rich plasma.  Your provider can describe the pros and cons of these different preparation methods.  Some systems provide cleaner, or more concentrated, PRP, but may lead to higher prices.  Ask.
