Selphyl is a method similar to undergoing a facelift except you never have to even go under the knife. The platelet-rich fibrin matrix uses your own blood to obtain platelets which in turn are injected as a dermal filler. Platelets-rich plasma stimulates the rebuilding of the underlying structural integrity of your skin. Patients notice new tissue and collagen growth quickly, as fine lines and wrinkles soften, and deeper wrinkled areas look plumper and smoother.
