Hello!

I'm a 19 yo female, and my problem is dark circles.
Growing up I never had dark circles and I know for sure they are not inherited.. Now it's been almost a month I got these massive under eye bags and blue/redish circles, I'm very tired and I my sleep is irregular, some days I can sleep over 12hours per day and some days I get 4 hours of sleep and some other days I get like 5hours of sleeps in the afternoon then I sleep like 6 hours at night. But lately I sleep in the average of 4-5 hours at night. I know it should be obvious that my dark circles are due to my sleep disorder, but I've heard many people complaining about accutane causing them dark circles, is it true? Since It's been 5 months that i'm on it.. If not, would my dark circles go away when I fix my sleep habbits? Is a good night sleep enough for them to disappear? Because I slept my full 10hours at night today and my eye bags got bigger.. Can they become permanent even though they are not inherited?

Thank you for your patience and help.
