Hi Welcome to Healthcare Magic Forum You have many post inflammatory and post trauma scars over your legs . Now these are very old lesions as they are present since your childhood days Topical medications can definitely be of help to you in reducing the pigmentation to some extent, although only after proper treatment, we can know the results Since these are dark scars, i would advice that you should use a lightening agent like kojic acid and vitamin c combination over the scars,,this is a simple, harmless lightening agent which can be used for as long the blackish pigmentation is there.. Also ,try not to touch the area too much Use proper sunscreen (spf 26) before going out in the sun so that the lesion doesn t darken any further Take a diet rich in vitamin C and antioxidants like Citrus fruits and lots of salads If after all the above measures, the scars tend to persist, then i would advise that you should see a dermatologist as there are various other measures for the treatment of pigmented scars like the use of chemical peels, dermabrasion etc which a dermatologist can decide according to the type of scars.. Hope it helps Wishing you speedy recovery Dr Geetika Paul
