Scars still red and stretched 2.5 years after mastopexy. What can I do to make my scars go white? (Photo)

I had a full mastopexy in 2020 but didnt strained my scars early on by doing housework. 2.5 years later my scars are still red/pink and white in other places but they have not faded much which concerns me. What can i do to make my scars go white? I am 40 in two years, good health and dont smoke
