These lesions can be electrofulgurated easily to lighten them up with no scarring but may need to be done a couple of times a 1 month intervals for roughly $350-500. Sincerely, David Hansen,MD
The lesions your picture shows seems to be seborrheic keratosis which are benign growth of the skin. The can be removed with a very superficial skin biopsy without leaving much of a scar. However I can not tell how much it will cost because it depends on Doctors' prices. It will be a cosmetic procedure.
