Welcome to HealthcareMagic fourm,
If it is not bothering too much then its better to leave it as it is.But use a good sunscreen daily when you go out in sun.if the scar is looking bad then go for fractional laser
.Consult a good dermatologist
a who has fractional co2 laser for scars
.You would require multiple sessions of the same for good result.If you can tell me where you belong to then probably i can suggest you a good laser clinic in india.
