Platelet rich plasma, also known as PRP, is widely used in medicine. It’s been used in orthopedic surgery for healing of fractures, in spinal surgery for bone grafting, in sports medicine and in ophthalmology. It is a safe procedure in which about 50 cc of blood is drawn from the arm, and the blood is separated into a platelet rich fraction by use of a centrifuge. Platelets are fragments of cells that contain growth factors that aid in would healing and the formation of new blood vessels and new cells. Platelet-derived growth factors have been shown to reduce wrinkles and stimulate the growth of new collagen and hyaluronic acid which plump the skin.
A study from Italy in 2010 in 23 patients demonstrated improvement in crow's feet, nasolabial folds, marionette lines, neck lines and overall tone and texture of facial skin after three sessions of PRP injections once a month for three months.
Acne and traumatic scars, stretch marks and hands can also be treated. Results are seen in 3-6 weeks and can last 18 months to two years.
Combined with laser resurfacing, PRP shortens healing time to less than a week and there's no risk of allergic reactions because PRP is your own blood product.
