In the absence of a traumatic wound, growth factors get to work repairing the structure of sun damaged skin. If you aren’t wearing high SPF sunscreen and donning a hat every time you step outside, then ultraviolet rays from the sun are constantly damaging the delicate skin of your face. Additionally, your body produces 1% less collagen every year after your 20th birthday. So even without constant sun exposure, the structures of your skin will slowly break down with time. PRP growth factors repair the damage. For example, platelet derived growth factor regulates collagenase secretion and collagen synthesis. Transforming growth factor regulates endothelial mitogenesis and epidermal growth factor stimulates endothelial chemotaxis.⁶
Platelet rich plasma injections deliver these bioactive healing compounds directly to the site of damage. For men and women hoping to rebuild sun-damaged skin, PRP is a safe and effective option without the unforeseen side effects of toxic or invasive procedures.
