I have a size-able keloid scar on my right knee and am seeking all course of treatment options to improve its appearance. I injured myself back in July 2023, and the injury took 1.5 months to fully heal. Currently I dress silicone sheet on my scar daily and just had one cortisteroid injection. Also I would like to know if it is ever possible for my scar to lighten and come close to matching my skin tone.
