You Slept 8 Hours. So Why Do You Still Look Tired?
ALLERGIC SHINERS
Allergy-related nasal congestion can contribute to dark circles beneath the eyes.
WHY SLEEP DIDN'T CHANGE IT
If congestion is contributing to the appearance, simply sleeping longer doesn't address that factor.
WHY YOU'VE KEPT NOTICING IT
The skin beneath your eyes is thin, which can make underlying discoloration particularly noticeable.
YOU MAY HAVE BEEN CHASING THE WRONG EXPLANATION
Another eye cream or an extra hour of sleep may not address every reason your under-eyes look dark.
