8 months back I got my first session of co2 fractional laser done over my stretch marks at my thigh and legs. The dermatologist used a pen shaped laser over my stretch marks for deeper burn and better results. But all the laser burn areas have become highly pigmented (dark brown) and isn't fading even after 8 months (insignificant fading). I am scared that these laser pih marks might never go. I have been applying kovijit plus (also using glyceric acid toner 8%) but the rate at which it is fading might take 2 years. Please help me. What better products should I go for?
