Dry under eyes stem from naturally thin, low-oil skin combined with aging, dry air, allergies, skin conditions, and certain medications.
The skin under your eyes is the thinnest on your body, with few oil glands, making it prone to dryness even when the rest of your face feels fine. Understanding the cause — often a mix of factors — is the first step to fixing it.
Why The Under-Eye Area Dries Out Faster
This region has far fewer sebaceous glands than other facial skin, weakening the skin barrier and accelerating moisture loss. Aging exacerbates this; the American Academy of Ophthalmology notes older adults are significantly more likely to experience both dry under-eye skin and dry eye disease, as tear production also declines with age.
Environment, Screen Time, And Lifestyle Triggers
Low humidity from indoor heating or air conditioning pulls moisture from thin under-eye skin, as do cold wind and dry outdoor air. Prolonged screen use reduces blinking, drying both the eye surface and surrounding skin. Smoking, alcohol consumption, very hot water on the face, and general dehydration can all worsen the problem.
Skin Conditions, Allergies, And Irritants
Common conditions like eczema, contact dermatitis, blepharitis, rosacea, and psoriasis frequently produce under-eye dryness. Allergies from pollen and dust are another trigger, worsened by eye rubbing. Harsh skincare products — fragranced moisturizers, alcohol-based toners, aggressive makeup removers — strip the delicate barrier. Switching to fragrance-free, gentle cleansers and avoiding hot water can help.
Medications And Underlying Health Conditions
The National Eye Institute lists diuretics, statins, antihistamines, decongestants, antidepressants, blood pressure medicines, birth control, acne medications, and hormone replacement therapy as potential causes. If dryness comes with redness, swelling, itching, discharge, pain, or vision changes, seek a medical evaluation. Do not stop any prescription medication without consulting your doctor.
How To Tell If It’s Dry Skin Or Dry Eye Disease
Dry under-eye skin is a skin barrier issue; dry eye disease involves gritty, burning, or watery eyes from a tear-film problem. Both often overlap due to shared triggers. The National Eye Institute’s overview of dry eye causes explains this. Address skin dryness first with gentle care — fragrance-free moisturizer, lukewarm water, a humidifier. If eye discomfort persists, consider a medical evaluation, especially if you wear contact lenses.

FAQs
Can allergies alone cause dry under eyes?
Yes, allergies contribute. Pollen and dust irritate thin skin, and rubbing worsens dryness. Minimizing triggers and using fragrance-free products often helps.
Does drinking more water fix dry under eyes?
Hydration supports overall skin health, but dehydration is rarely the sole cause. Key factors — thin skin, few oil glands, aging, environment — persist regardless. Direct moisturization is more effective.
Can makeup cause dry under eyes?
Harsh, alcohol-based removers, fragranced products, and aggressive scrubbing strip natural oils. Switching to gentle, fragrance-free cleansers and avoiding rubbing reduces irritation.
