i can understand your physical and pshycological distress.
The thing is that the scar removal is a complicated process,it depends upon several factors like its structure,texture,thickness and location etc.
The consultation should involve a Skilled dermatologist
plus a plastic surgeon to decide what treatment option would give the best results.
Ur question really depends on how does your scar looks and which type of lasers you have been offered and by whom?
I hope you can understand my point,but one advice that i can give you right now would be to have a second third and may be a fourth opinion from dermatologists and plastic surgeon before you decide what to do,i mean there is no harm in it.
thanks very much and all the best.
