“Thanks to modern science, we now know that platelets contain various factors that stimulate the production of collagen, elastic fibers and new blood vessels,” says Mandeville. “Microneedling causes direct trauma to the skin. As a result, the body rushes to repair the wounds, sending platelets and cells to the rescue. As platelets play a significant role in terms of growth factors, it seems particularly appealing to inject the plasma back into the skin through the punctured holes to really speed up the healing of the tissues.”
In general, you’ll want to increase your water consumption for a day or two prior to the appointment. This helps increase the volume of blood in your body, making the PRP process much easier. You’ll also want to avoid blood thinners, if at all possible, for up to two weeks prior to appointment. These include over-the-counter pain medications and vitamins. Do not stop prescription medication blood thinners without first consulting with the doctor who prescribed them to you.
So, what is it and how does it work, exactly? Don't let the name fool you. In fact, "It's usually done in full light of day," says Beverly Hills-based dermatologist Ava Shamban. In all seriousness, the treatment is a "combination of a microdermabrasion, followed by the application of PRP (platelet-rich plasma)," says Shamban. "The PRP is derived from the serum portion of the blood, which contains platelets. The platelets contain high levels of growth factors, which, when applied to the skin, will stimulate cell turnover."
