Hello sir. Scars these days have got many ways of treatment. Varies from person to person, depending upon the skin type, scar maturity, length, position and width. The treatment might vary from few lightening creams, compression, silicon treatment, superficial dermabrasion, dermarolling, fat grafting to the scar revision surgeries. Personal examination or atleast the complete details of the scar might help in suggesting the suitable treatment or a prophylactic measures to prevent the scar formation.  You can consult me online with the pictures as well. Thank you.
