I had one session of PRP and saw no difference. They do say that you need 3 sessions to see a difference but after spending £500 on the first session I was reluctant to potentially waste another £1000 on two more sessions. I found it hard to believe that after the second or third session I would suddenly see a difference after seeing nothing from the first. Also, I had a lot of bruising - about 5 bruises of different sizes over different areas of my face. So the downtime from that was also not worth the lack of result. I had the treatment mainly for the under eye area but there was plenty of PRP left over so she used it in other areas of my face as well. I didn't see any noticeable difference in any of the areas. If I had loads of spare money I was happy to waste I would probably have more sessions, just to see if it started to take an effect but it's not worth the £1000 gamble.
