Treatment Options to Lighten Dark Brown Scar on the Knee?

Good day! I'm a female, Asian. with a fair complexion. I got it when i was 12y/o, and now I'm 22, i cant wear shorts and skirt because my scar on the knee was obvious and it was really annoying and it makes my self confidence and self esteem become low. Is there any treatment or topical cream or home remedy that you can suggest to lighten my old dark brown scar on the knee? thank you and Godbless!
