About Facial skincare routine while on isotretinoin

This routine is meant to help fade my acne marks, reduce inflammation, keep acne causing bacteria on my skin at bay and reduce the unevenness of my skin due to acne scars, all while helping support my barrier and keeping my skin hydrated throughout my oral isotretinoin treatment. I am currently on only 20 mg five days a week, so my dermatologist thinks I can also use other skin actives as long as my skin barrier isn't damaged by it.

I also have really dark circles under my eyes despite my light skin tone no matter how much rest I'm getting so I'm also trying to tackle that.
