PRP, used as a skin treatment, has been studied and tested quite rigorously, with a multitude of articles published in credible, peer-reviewed medical journals. In one particularly compelling study published by the Journal of Drugs in Dermatology, 23 patients were treated once a month for three months. Each had an injection of PRP plus an activating solution introduced into strategic places on their faces and necks.
Medical imaging, digital photography and a dermascope were used to see and record the before and after results. At the end of the trial, each participant had visible results and experienced little to no side effects.
