Celebreties are raving about it, doctors are promoting it for many things, but is it really worth the hype?
In short, PRP is not FDA approved for anu Dermatologic or Cosmetic indication. There are several small studies that concluded that there is benefit when treating androgenic alopecia. That being said, larger, well-designed studies are needed. For other indications, such as photo-rejuvenation, studies are even more poorly designed.
There is a good scientific basis for why PRP may help a variety of conditions. Unfortunately, due to a lack of good clinical studies further research is needed. So the answer to the question of whether is is worth the hype is maybe.
Often, PRP is combined with another procedure–laser resurfacing+PRP, or Restylane+PRP. When doing so, it is difficult to know if the PRP is adding any benefit.
It’s funny today. No matter what the condition, everyone thinks that a “laser” is available and is best. In most cases, this is not so, but in many cases, laser treatments are available.
There are many different types and causes of scars: traumatic, post-surgical, and acne scars to name a few. Well, there is not one treatment that is best for all types of scars. So, when it comes to scars, you need to have a lot of tools at your disposal in order to get the best result. For example, here is a list of treatments that I perform regularly for scars:
- CO2 laser ablation
- Dermabrasion (not to be confused with microdermabrasion)
- TCA peels
- IPL (intensed pulsed light)
- Topical treatments (i.e. silicone gel sheets, 5-FU), which can be combined with other treatment modalities
- Surgical scar revision
- Dermal and/or subdermal fillers
What is not on the list:
- Microdermabrasion – studies have shown that there is virtually no benefit unless one reaches the dermis( pinpoint bleeding), at which point it is a dermabrasion and not microdermabrasion. This modality can be combined with chemical peels, which does offer benefit.
- Microneedling – although there may be some benefit, the cost-benefit ratio is poor (high cost for minimal, if any, benefit). This is frequently recommended as there is minimal risk.
In short, the treatment of scars requires experience and skill. More and more frequently, I perform post-operative treatments to reduce the appearance of scars before they fully form (i.e. 10-14 days after facial surgery). But, most scars that are treated are from acne and/or trauma.
