Were is your PWS located? Laser is the best option for treating pws, but results depend on the depth of the stain. The medical reason to have laser therapy is to avoid possible thickening of the stain, cobbles or blebs that occur as you age. Into your 20's is when this may occur. It may not, but I havent' seen your pws (can you email me a picture). I would also recommend that you email your information and picture to Dr. Stuart Nelson from the ask the expert on the main page of this site. Dr. Nelson is very responsive and can give you more details on what benefits you may see. Insurance companies do cover this if the proper steps are taken to get it approved.
