What would be a permanent solution for under eye hollowness and Dennie-Morgan folds?

A while ago I noticed my eyes seemed sunken in my face, with dark discolored hollows beneath the lower eyelid. Furthermore, I noticed Dennie-Morgan folds on my lower eyelid. While I do have a deviated septum which will be fixed as soon as the COVID-19 pandemic subsides, my ENT told me that maybe the dark circles would go away, but not the hollowness nor the Dennie Morgan folds. What would be a permanent solution for those? I don't have atopic dermatitis, so the Dennie Morgan folds are genetic
