How to get rid of hereditary dark circles under eyes?

No luck: Consider filler injections or hide with creams.

Dark Circles: Circles under eye can be due to: allergy "allergic shiners", fatigue, genetic variation, aging. Lower lid skin is very thin so blood vessels under skin can make area look dark. Topical creams/fillers can help hide circles: only mask condition with no cure. What helps: drink 8 cups water/day, sunblock, hat, enough rest; avoid rubbing; makeup; facial plastic surgery when severe; allergist can help.

Cosmetic Bleph: You may want to consider cosmetic blepharoplasty to tighten the lid skin and reduce the amount of discoloration. Actually, there are very few long lasting treatments for this condition and if cosmetic cover up does not satisfy you, then consider a cosmetic plastic surgeon or oculoplastic surgeon for blepharoplasty considerations.
