I underwent PRP injections mainly out of curiosity. I was slightly sucked-in by the claim that it was used for burns victims to regenerate skin (further research revealed that it has only been used medically in bones, not skin). I was told that I wouldn't see anything for a month. I never saw any change in my skin. I was especially hoping for some rejuvenation of my eye area, having heard that one of the salon's clients had replaced her Botox with PRP. I hoped to be able to do that same.
For $300 I wouldn't mind if the results were invisible, but for $1,000 per treatment, with a recommendation that I sign up for more than one, I honestly couldn't recommend it. I would steer clear and go for Fraxel or something similar which you can see working in front of your eyes.
The practitioner was great but I think she had been sucked in by the hype too. I will go back but I won't ever spend that much again on something I am unfamiliar with.
Also, I had a couple of vouchers.. Just little 'frequent buyer' discounts. They weren't accepted due to some mysterious terms and conditions which I didn't receive with the loyalty incentive. So it was very awkward for all, and didn't feel like a 'reward' at all.
