for scars:-Fractional Laser treatment is needed,one session in 1 month upto 6-8 sessions,treatment can be done by a dermatologist. Other options are Chemical Peels / Microderma Brasion / Derma Roller.

Hello there...... For these scars you can use cocoa butter or vitamin E creams. Topical treatments with acids and chemical peels can be effective but can take a while for the skin to totally revert to its normal color.  Microdermabrasion can also be done, but this might require several sessions.  Skin resurfacing using lasers is also an option. ... Consult Dermatologist for further evaluation and treatment.....
