Thanks for your reply Kim. I knew before the treatment that she was on new medication for her condition but not the exact name of it. I don't think the bruising was related to the medication on further thought, although her skin may have been abit more sensitive, I think it was due to a new product I'm using, it isn't very good. It's a Gigi sugar wax and it is completely different to the other sugar brands I have used. I think it was probably a lot stickier than the usual one I use and pulled the skin more. My consultations are usually really thorough for new clients/treatments, I'm not too sure of how much of a consultation you need to give for regular clients, It's usually just a quick check to make sure their last visit was fine and no problems inbetween. I think this was a bit of a wakeup call to just be a little bit more thorough.
