Valley white scar best treatment?

I had a lip lift 3 years ago, right after valley white scar formed, it is also pink without makeup. I’ve tried CO2 3 times and microneedling twice, I do not see any improvements. What else I shall try? Revision surgery is drastic and no guarantee it will be any better. What type of laser is best? If I cannot get rid of valley, at least I need to address the color of scar to Match my skin. Thank you
