I had 4 sessions and I feel I am wasting my money. I am quite dissappointed with this kind of laser as it is not as effective as the other one I tried before. They do it too quick and areas should be marked to make sure it was in detail to all the area. The fact they have to wear glasses to do the laser it does not help because they are not precise to go in detail to the area, that is why they should mark them. In one of the sessions the member of staff was 1 cm from the area and the next session with different member of staff she was 3 cm doing it.
