cost of treatment depends upon the body site you need to get the laser
done.Every center has its own way of dealing ,but since patient require multiple sessions ,centers offer package system to patients.
In "package system" patient has to pay in bulk for say 3 or 6 sessions ,which they can take at every monthly interval.
Another way is "per sitting system" ,where in you pay each sessions and take a sitting of laser.This would come out to be more costly than package system.
Approximately for say chest area it may cost 25000/- for 6 sessions.This may vary from center to center.
I've no idea about udaipur,but I know about Delhi where i've worked for more than 10 years .So I can guide you to a good laser center in delhi.
