How many treatments of PRP in the eye troughs are needed initially? (Photo)

With a high quality (concentrated 5-7x baseline platelets) Prp, I’ve seen under eye circles go away in 1-2 treatments. In many cases, the underlying causes of dark under eye circles need to be addressed in order to prevent them from developing again. Working with a functional medicine doctor can help to address the hormonal and nutritional side of dark under eye circles. 

How the prp is administered in this area and the quality of the prp can determine the result, so being the first may not be the best idea even in the hands of a plastic surgeon. There is no other injectable that is administered the way Prp needs to be administered under the eyes so it may not be as easy as injecting in the same place where the fillers were placed. Working with a doctor specializing in regenerative aesthetics is the ideal way to ensure you are getting a potent regenerative agent utilized in the right way for the the effect you are hoping to achieve. 

I think PRP is a great idea for your case to build collagen and help fill the tear trough, but will need at least 3 sessions about 4-6 weeks apart to start with, and probably 4-6 sessions overall. The results will be long term meaning a few years, and you will require ongoing maintenance sessions 1-2 times per year to keep desired results. I would also combine PRP with ultrasound  and radiofrequency for best results. Good luck from Las Vegas .
