Hi,
Thanks for writing to us.
Treatment of the scar formed depends upon the type of scar. The procedures that can be done are
Subscision
dermabrasion
Microdermabrasion
Trichloroacetic acid 50 to 75% concentration application( CROSS)
Lasers
No treatment can guarantee 100 percent result but a suitable procedure according to type of scar would definitely reduce it.
Laser if required can be taken and when done by a qualified personnel has no side effects.
Hope that helped
