In recent years doctors have found that by utilizing the growth factors found in the blood (specifically the platelets), a physician can activate stem cells already in the skin to grow new, younger-appearing skin.


  • PRP injections can increase youthful skin thickness and elasticity
  • PRP injections can reduce yellowish skin appearance
  • PRP injections can lessen appearance of wrinkles

There has been a lot of research suggesting how PRP works on damaged skin and wrinkles. A September 2017 study in the Aesthetic surgery journal (1) found that after an injection of PRP (Platelet Rich Plasma, see video below), doctors observed an increase of reticular dermis thickness (the lower of the two layers of the dermis (skin)). This thickening of the skin was caused by deposition of elastic fibers (the stuff of skin elasticity) and collagen, with a fibrotic aspect (skin regeneration). The researchers concluded: “PRP injection could lead to trophic (bringing blood) alteration of the skin and the precocious (premature) aging process.”

PRP for Acne Scars

We are often asked, “Can you help with acne scars?” For many the answer is yes. We have seen many patients over the years with various levels and degrees of acne scaring who have benefitted from our PRP treatments. What are our PRP treatments and how do they work?

First, I want to provide some basic information.

  • Platelet Rich Plasma (PRP) is a blood product that comes from you. We draw your blood and then spin it in a high speed centrifuge to separate the plasma from the red blood cells. What is left are a “platelet rich plasma” that contains concentrated growth factors and healing cells.
  • “Micro-needling,’ gently pricking your skin stimulates the creation of new skin cells and regeneration of damaged cells. Your own PRP is then massaged into the skin. The goal is to stimulate the production of collagen and elastin, and the creation of new skin cells.
  • Subcision, also called as subcutaneous incisionless surgery, is a minor surgical procedure for treating depressed scars using a hypodermic needle inserted through a puncture in the skin to to break the fibrotic strands, (which pulls the skin downward creating the scars). The strands also connect the scar to the underlying or subcutaneous tissue.
