Dark circles under your eyes can be more than just a cosmetic nuisance—they can make you look tired, stressed, and less like your best self. Unsurprisingly, so many people turn to concealers, expensive skincare products, or even clinical treatments to get rid of them. But what if the cause isn’t what you think?
We know the usual suspects: lack of sleep, too much stress, smoking, or long hours of staring at a screen. But researchers say there’s another lesser-known culprit right beneath your nose.
Allergies Could Be to Blame
According to health experts, allergic rhinitis—commonly known as hay fever—may be the hidden trigger behind those under-eye shadows. It’s not just about sniffles and sneezes. Nasal congestion caused by allergies can interfere with blood flow in the delicate skin under your eyes, creating what some dermatologists call “allergic shiners.”
Here’s how it works: When your nasal passages are congested, blood pools in the veins under your eyes. That buildup leads to the appearance of dark circles. As a result, even if you’re well-rested, your face might still tell a different story.
The Allergy Triggers You Didn’t See Coming
Allergic rhinitis occurs when your immune system overreacts to harmless substances like pollen, dust mites, pet dander, or mold. Once exposed, your body releases histamines, triggering a cascade of symptoms—runny nose, sneezing, nasal congestion, and yes, those under-eye shadows.
And for city dwellers, there’s more bad news. Air pollution and fine dust can worsen allergy symptoms, making dark circles more persistent. Stress and genetics also play a role—if your parents have allergies, chances are higher that you’ll experience them, too.
What You Can Do
Fortunately, managing allergic rhinitis is very doable. Over-the-counter antihistamines, decongestants, and nasal sprays can help reduce inflammation and improve airflow. Identifying and avoiding your specific allergy triggers is also key. Steering clear can bring significant relief, whether it’s seasonal pollen or a pet you’re allergic to.
Bottom line: If you’ve tried everything to fight dark circles, and they still won’t budge, it may be time to consider what’s happening inside your nose. Treating your allergies might be the secret to looking (and feeling) more refreshed.
