I am writing on behalf of my girl friend who is having big birthmarks on her back and hence she couldn't wear sleeveless tops because that looks very weird when it is visible. Post marriage we will be planning for some treatment by which that mark gets hidden permanently without any side effects. Can anybody suggest what kind of technique is used to remove birth marks, moles which I believe laser technique. Is it safe? How long does it takes to get hidden completely? Is it painful? And do this have any side effects? Can you recommend best doctors or dermatologists in Mumbai?
