Well, laser hair removal works best if ur skin is light. If u have dark skin, the mark will be realli "white". im not sure if its permanment. might be long lasting term effect.

Yes, that is one of the side effects. Your doctor should have gone over all possible side effects with you before you had it done. I think a lot of people fail to realize that there are side effects for all of this stuff, some of which are worse than the initial issue.
