Hello. I have been on Accutane for the last 5 months. My acne is clearing and I have no new breakouts, however I have lots of red marks where the acne was (post inflamatory hyperpigmentation possibly?)? Anyway, I was just curious if blue light or red light treatment would help, and can I use the light treatment while on Accutane? If not, what else could I do to reduce the appearance of the red marks? The acne is on my chest and is very hard to look at. I live in Florida and it is very hot and I cannot take off my shirt with this look. It seems to not be fading at all. Thanks for your help.
