Depending on your skin type certain laser treatment machines will either burn your skin or just won’t do you any good. What you should expect is an explanation of the quality of treatment. There are many machines for each type of skin, so there could be a case when experienced technician can give you better laser skin treatment on the available laser machine than someone with three hours of the training on the best machine ever. It takes two (machine and technician) to get the best result, so keep that in mind.
