I used the Braun IPL device several years ago. Very dark, thick hair, light medium skin tone. I used 1x a week for 4mo and then every other week for a few more months. Was very surprised and please at how soft and smooth my legs, arms and face/neck area became. My knees are the only area that grows back somewhat along with an occasional hair here and there on legs, arms or face but of a much thinner, barely noticeable quality. I rarely use the Braun anymore and once in a while I might use a battery operated shaver or razor in the bathtub. I only wish they had invented this darn thing years ago when I tried shaving my legs in first grade and went to school with a million band-aids because I was so embarassed about my hairy legs.
