Your surgeon draws blood from your arm (not your neck, as many a movie vampire has been known to do) and spins it to separate out the plasma, which contains platelets. These are the proteins and growth factors that may stimulate collagen production and thereby promote skin regeneration and rejuvenation. There are several kits available to isolate these growth factors, and platelet-rich plasma (PRP). Once collected, the PRP is injected back into your face.
8)    Watch and wait: Growth factors contained in the plasma stimulate the release of the skin’s stem cells. The skin is being tricked into believing that it has been injured and must heal itself with new, fresh tissue. This somewhat sneaky process allows the skin to create new collagen, new blood vessels, and new cells. The results will not be immediate, so while you patiently wait a few weeks and even a few months, your skin will begin to transform itself.
PRP is a concentrated source of platelets, growth factors and cytokines produced naturally in your own body, and stimulates and controls healthy regenerative processes, including collagen and soft tissue remodeling, and thereby improves overall health and rejuvenation. PRP has been used successfully for years to promote improved healing times and optimal results from various surgical and non-surgical procedures. The PRP, painlessly obtained through a small blood draw, is injected after dermal filler and enhances the results of this amazing procedure.
But, you know what wasn’t disappointing? The day-three results. While the hours immediately following the hour-long appointment were characterized by an unsightly red, ultra-puffy complexion (which was really just exacerbated by the fact that I have sensitive skin), with the help of an even layer of Alastin Regenerating Skin Nectar (the post-treatment product Dr. Peredo told me to use for the next week), by day two it looked like I had a low-key sunburn and day three my skin looked radiant and refreshed. 
Platelets, Zeichner explains, are rich in growth factors, which essentially act as energy boots for our skin. This helps our skin function optimally, increasing everything from collagen to elastin, while also bringing antioxidant and hydrating properties. "Platelet-rich plasma is now commonly used topically as part of a regular facial, used along with microneedling to enhance penetration into the skin, and is even being injected into the skin in the same manner as dermal fillers," says Zeichner.
