Dark Under Eye

Why Do I Have Dark Circles Under My Eyes?

1. Histamine Buildup

High histamine levels (from food, stress, or poor detox) can cause blood vessels to expand and leak slightly, especially under the thin skin around your eyes. This creates a purplish or bluish tint—often called “allergic shiners.” If you also struggle with allergies, congestion, or food sensitivities, histamine could be playing a role.

2. Food Sensitivities

Certain foods like dairy, gluten, or eggs can cause low-grade inflammation in the body, leading to puffiness and discoloration under the eyes. If your dark circles get worse after eating specific foods, this might be worth exploring. Consider asking your doctor about a food sensitivity test!

3. Gut Health Issues

A sluggish or imbalanced gut can interfere with nutrient absorption and contribute to inflammation. Your gut also plays a role in clearing histamine and supporting liver detox—both of which impact the appearance of your skin.

4. Liver Overload

Your liver works hard to filter out toxins, hormones, and histamine. If it’s overburdened, waste can build up in the bloodstream, leading to signs like dull skin, breakouts, and—you guessed it—dark under-eye circles.

5. Nutrient Deficiencies

Low levels of iron, B12, or folate can reduce oxygen delivery to tissues and weaken the tiny blood vessels under your eyes. This can make the area look darker or more sunken.
