Burn Scar Reduction?

Hi am 22 years old .Accidentally i met with hot water burn on my foot . I went near plastic surgeon immediately and I was treated with collagen . After 1 month the scar got reduced from red to white .I consulted surgeon again he prescribed me stocking(for not forming kelloids)and to use hexilane silicon gel on my scar for 4 months. I completed medication and I waited 7 months till now but my scar is still in white color. Please tell me how to change my scar color to my skin color.
