Hello, I am a tanned skin African American who is looking to complete the second course of Accutane for back and face acne. I would like to do the CO2 laser as soon as possible for the indentations on my face left from cystic acne. How soon after accutane is it generally safe to get C02 laser and how long will the hyper pigmentation last after C02 laser? Is it typically temporary or possibly permanent if hyperpigmentation occurs? Thank you so much for your answers!
