My 1st laser treatment, so nothing to compare to, but this is one of the best Groupon purchases I`ve ever made! I was hesitant at first, but my dermatologist said that the only way I would be free of scarring on my neck from acne was to get the hair removed, and it had to be the YAG laser because of my skin tone. There have been different people providing the service each time, which some are more thorough than others, but overall I haven`t been disappointed.
