How can i fade discoloration 5 months after lipo/fat graft to the breasts?

its been 5 months since my lipo/fat graft to the breasts, the insicions sites are darkly pigmented. six insicions from my abdomen and four each on my breasts which are very small. the ones on my abdomen however are quite large, i measured them and they are a centimeter in diameter. they're slightly indented and very discolored, i have medium skin tone, how can i fade the discoloration ? its been five months post op and im afraid that the discoloration will be permanent.
