23 Jun I don’t have a problem sleeping, so why do I have such dark circles?
A few culprits may have you reaching for the under-eye concealer. Sinus blockage triggered by a food or seasonal allergy can cause swelling of the tiny blood vessels near the surface of the skin, giving you “darkened” areas around your nose and eyes. An allergist can determine an allergy trigger, but if yours is seasonal or the irritant is unavoidable, an OTC drug like Claritin or Zyrtec should help.
How’s your diet? A vitamin deficiency may also cause circles. Take a daily multi if you don’t already, and add a night cream or facial mask containing vitamins K and A (aka retinol) to your regimen.
