Is PRP for the face effective, and does it have side effects?

Thank you for your question about the PRP (Platelet Rich Plasma) procedures.  Typically it is done by way of drawing the patient's blood, spinning it down in a centrifuge, drawing off the layer of Platelet Rich Plasma, then microneedling it into the skin.  The PRP can also be injected into areas of the skin, including the scalp....which helps with hair rejuvenation.  By using a patients own PRP you can get the benefits of their own growth factors which can stimulate collagen production.  This will decrease fine lines and wrinkles, improve skin texture and tone, minimize pores, even treat acne scarring and stretch marks.  When using the PRP (platelet rich plasma) microneedling technology for facial rejuvenation it is likely you would need 1-2 a year to achieve and maintain desired results.  For hair rejuvenation, scar treatment, stretch mark treatment, or treatment of melasma/pigment issues it will likely take multiple consecutive treaments.  There is little to no down-time with PRP microneedling, but avoiding the sun is always a good idea after any facial cosmetic procedures.  With injections there is aslo always risk of bruising and swelling.  
To be sure, see two or more experienced, licensed and board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps.

Yes PRP is very effective. When injected into the body it releases growth factors that help repair, rejuvenate and remodel damaged tissue. By doing PRP,fine lines and wrinkles are improved, texture and evenness of the skin is also improved, improvement in pore size and reduction of pigmented lesions are also common.
There are no major side effects. You can have some bleeding or bruising and swelling for a few days at the most .

PRP therapy has been proven safe and effective. Itcarries almost no adverse effects since the patient will be using their ownblood. This blood will not be drawn out and injected back in. It will be spunfirst in the centrifuge to isolate the plasma that will be used on your problemarea.
Should you encounter some side effects or down timesuch as redness, swelling, or bruising - these would subside on their own inabout 72 hours to a week.
