Sebaceous glands never returned to normal after Accutane

I have been off of Accutane for nearly 4 years now. I have suffered extremely dry skin as a result to the treatment. The most susceptible spot is on either side of the nose, right where the crease. I have tried many moisturizers, but currently I am washing and moisturizing my face with argan. I just started using at home red light therapy so we will see how that helps with my skin. Please offer me any advice, because my skin has not been able to produce its own oils since Accutane.
