I have been having laser treatments on my legs and underarms. The pain on my legs is minimal, and they use a numbing creme on my underarms before the procedure, so no discomfort there either. Make sure you research the different lasers to find the best one for your skin tone, some are better than others

I don't know about long term reduction yet, but so far am happy with my results, I have had about 5 treatments and have about 50% reduction on my underarms and 75% on my legs. As for other food free rewards... manicures, fancy skin creme, trip to amusement parks or whatever you enjoy, magazines, books, shoes....
