I am exactly 2 years post breast lift. My scars are flat but it's the brown pigmentation that bothers me. See attached photos. I have olive skin Post surgery I used silicone sheets for a year. 7 months ago I got a CO2 laser treatment (3w power, 250 micrometers, stack 1 in spray mode). Then 6 months ago I did the Pico laser (1064nm wavelength at .8j/cm2 using a 9mm round transducer). No difference from either :( What would you suggest?
