Intro to PRP, Richard Weiss MD 1 Introduction to PRP (Platelet Rich Plasma) Richard Weiss, MD March 14, 2017 PRP is being widely used by itself and in combination with laser skin rejuvenation to reduce facial wrinkles and improve the tone and texture of the skin. Within the last six months, I have incorporated this technique into my practice. Having seen many ‘fads’ come and go in this field, I am cautious about the evaluation of new methods. In the case of PRP, because the results are frequently less than 100% (in other words, we really can’t make 60 year-old skin look like a 20 year-old – at least, not in everyone!) it is especially important to have a healthy skepticism about excessive claims. In the case of the PRP technique, I thought it might be interesting for me to explain exactly what PRP does, and to quote some of the scientific evidence in peer-reviewed publications that has convinced me that PRP is an important new addition to rejuvenation procedures. I often mention to my patients that I am also a scientist with 2 patented inventions and many published papers. With that in mind, I’d like to summarize some of the data that supports my clinical impression (based on my patient’s improvements) that PRP works – my evidence-based conclusion – by quoting some peer-reviewed scientific studies. What are platelets? Platelets are a blood component whose main function is to stop bleeding. We all have platelets. It turns out that platelets also have granules that, when activated, release more than 10 growth factors (GFs) that not only attract more platelets to the area but also stimulates new collagen production and many other processes that are beneficial to healing and healthy youthful skin appearance. “Platelet derived growth factors’ main functions are to stimulate cell replication (mutagenesis) of healing capable stem cells.” (1) Platelets contain α granules, which comprise cytokines, growth factors and bioactive proteins essential for tissue repair and healing. What is PRP therapy? “In recent years, autologous platelet-rich plasma (PRP) has been proven to promote wound and soft tissue healing and collagen regeneration.”(2) This progressive non- surgical healing treatment “has been used successfully in orthopedic, vascular, oral and maxillofacial procedures, as well as cosmetic skin improvement. (4) It has also been used in Ophthalmology for years to speed epithelial wound healing of the cornea. “Because PRP also enhances soft tissue mucosal and skin healing, it is used in connective tissue grafts, palatal grafts, gingival grafts, mucosal flaps together with Alloderm (BioHorizons, Birmingham, AL) for root coverage, skin graft donor and recipient sites, dermal fat grafts, face lifts, blepharoplasty, and laser resurfacing surgery.” (8)
