I constantly look tired I've tried dark circle cream, I have allergies I take medicine for it what else could I try so I don't look so tired?

Nasal congestion. Studies have correlated the degree of the dark circles to the severity of nasal congestion. Oral antihistamine does not provide decongestant effect and thus you should try OTC nasal steroid. If the problem fails to improve after a month, consult an allergist.
