Welcome To HealthcareMagic forum,
marks and cut marks the best thing would be the laser
resurfacing.There are fractional lasers available with lot of laser clinics which you can go for.Next to that i would suggest would be dermaroller
with chemical peel procedure .you need multiple sessions with that.
I am situated in bhilai chattisgarh working at apollo hospital .If that is close to you ,you can visit me for treatment.Else I can give you address of clinic in delhi who are doing this treatment .I was working in Delhi for 10 years ,so i can guide you to a good clinic.
