Lovely ladies but the laser just didn't work so I feel like it was a bit of a scam. I've since done some more research and apparently the type of laser they use (Candela GentleYag) is good because it can be used on all skin tones but may take more sessions for people with fair skin (like me) than other types of laser.
Also I signed up with a deal and on my last session they questioned whether I had already paid for everything - very stressful - so if you have a 3 for 2 deal get it in writing!
