I know you’re on accutane but your health indicators are not on the higher end.
Focus on hydrating your skin and hair and also the skin around the orbital area in all means to get rid of dark eye bags.
For that dark area I recommend kojic acid,I’ve been using it for a but over 2 weeks now and I’ve seen a moderate difference but it’s good.
I don’t have an exact routine since I basically just sit around all day randomly do things at possible moments so I also recommend dyeing your eyebrows and eyelashes.
So
Eyebrow and eyelash dye,kojic acid,leanmax,moisturizer for your hair and also your skin.
