Red Under Eyes: 7 Possible Causes (& What to Do)

Red under eyes is a common symptom that usually points to irritation or inflammation of the delicate skin around the eyes. It often appears as redness, dryness, or swelling in the lower eyelid area and can be linked to skin conditions or mild infections.

Red under eyes are most often caused by eczema-like conditions, allergic reactions, or irritation from everyday products. In some cases, infections or chronic skin diseases can also lead to persistent redness in this area.

Treatment depends on the cause and may include avoiding triggers, using gentle skincare, or taking medications to reduce inflammation or infection. Medical attention is recommended if symptoms worsen, spread, or are associated with pain, fever, or vision changes.

What causes red under eyes?

The main causes of red under eyes may include:

1. Periocular (eyelid) dermatitis

This condition is a type of eczema that affects the eyelids and nearby skin, often caused by allergies or irritation. It is one of the most common reasons for red under eyes. The skin in this area is very thin, which makes it more sensitive to triggers.

People with this condition often notice itching, burning, and dry or scaly skin around the eyes. Swelling is also common and may cause puffiness, especially in the morning.

In long-term cases, the skin may become thicker or darker due to repeated irritation and rubbing.

What to do: Treatment involves identifying and avoiding triggers like cosmetics or skincare products. Mild topical medications and moisturizers are often used to reduce inflammation and repair the skin. In persistent cases, medical guidance may be needed to adjust treatment safely for the eye area.

2. Allergic contact dermatitis

This occurs when the skin reacts to substances such as makeup, fragrances, or eye drops. It is a frequent cause of sudden red under eyes and can develop even after using a product for a long time. The reaction happens when the immune system responds to a specific substance.

The affected area usually becomes red and swollen, often with itching or discomfort. Some people may also notice small blisters, oozing, or crusting in more severe reactions. The rash is usually limited to the area that came into contact with the allergen.

What to do: Treatment focuses on avoiding the allergen and using anti-inflammatory creams when needed. Patch testing may help identify the exact trigger causing the reaction. Switching to gentle, fragrance-free products can also help prevent future episodes.

3. Irritant dermatitis

This type of dermatitis happens when the skin is damaged by harsh products or frequent rubbing. It can lead to red under eyes due to irritation of the delicate skin barrier. Unlike allergic reactions, it does not involve the immune system.

Burning and stinging sensations are common, along with dryness and flaking of the skin. The area may feel tight or sensitive, especially after washing the face or applying products. Symptoms often affect both eyes, particularly when caused by cleansers or environmental exposure.

What to do: Treatment includes stopping the use of irritating products and switching to gentle skincare. Moisturizers help restore the skin barrier and reduce discomfort. Short-term anti-inflammatory treatments may be used if symptoms are more intense.

4. Atopic dermatitis

Atopic dermatitis is a chronic form of eczema that can affect the eyelids and under-eye area. It often causes recurring red under eyes, especially in people with allergies, asthma, or sensitive skin. The condition tends to flare up and improve over time.

This condition typically causes dry, itchy patches that may become thickened with repeated scratching. The skin around the eyes may also appear darker due to inflammation and rubbing. Other areas of the body, such as the neck or arms, are often affected as well.

What to do: Treatment includes regular use of moisturizers to protect the skin barrier. Avoiding triggers like harsh products or allergens is also important. In more severe cases, doctors may recommend prescription creams or other treatments.

5. Periorificial dermatitis

This is a skin condition that causes small red bumps around the eyes and other facial areas. It can develop after using certain creams, especially corticosteroids or heavy moisturizers. The condition may also be linked to certain cosmetic or hygiene products.

It often presents as clusters of red bumps on irritated skin, sometimes with mild burning or sensitivity. The surrounding skin may look dry, rough, or slightly scaly. In some cases, similar changes may also appear around the mouth or nose.

What to do: Treatment usually involves stopping the triggering product, which may initially worsen symptoms before improvement. Topical or oral medications are often used to reduce inflammation. Recovery may take a few weeks, and patience is important during treatment.

6. Periorbital cellulitis

This is a bacterial infection of the skin around the eye and can cause significant red under eyes. It is more common in children but can occur at any age. The infection usually develops after minor injuries, insect bites, or nearby infections.

The area around the eye may become red, swollen, warm, and tender to the touch. Fever can occur, especially in younger individuals or more severe cases. Unlike more serious eye infections, vision and eye movement are usually not affected.

What to do: Treatment requires antibiotics, either oral or intravenous depending on severity. Close monitoring is important to ensure the infection does not spread. Medical evaluation should be done quickly to prevent complications.

7. Other skin conditions around the eyes

Some less common skin conditions can also lead to red under eyes. These include seborrheic dermatitis, rosacea, and psoriasis. Each condition has different underlying causes but can affect the same sensitive area.

These conditions may cause flaky patches, persistent redness, or inflamed areas around the eyes. The skin may appear oily, scaly, or thickened depending on the condition. Symptoms often appear alongside similar changes on the scalp, face, or other parts of the body.

What to do: Treatment depends on the specific condition and may include medicated creams or gentle cleansing routines. Avoiding known triggers can help reduce flare-ups. Some cases require long-term management with medical supervision.

Red bumps or rash under the eyes: what could it be?

Red bumps or a red rash under the eyes are usually caused by skin irritation or inflammation, such as contact dermatitis, periorificial dermatitis, or eczema.

The possible cause can vary depending on the appearance of the skin and whether other symptoms are present, such as itching, burning, swelling, or pain.

Red bumps under the eyes

Red bumps under the eyes may be caused by periorificial dermatitis, a skin condition that causes clusters of small, red bumps, sometimes accompanied by dryness, burning, or irritation.

It may be triggered or worsened by corticosteroid creams, certain cosmetics, or heavy facial moisturizers. Similar bumps may also appear around the nose or mouth.

Other possible causes include allergic contact dermatitis, which can cause itchy bumps or small blisters after using makeup, eye drops, or skincare products. Insect bites, rosacea, and styes can also cause redness or bumps around the eyes.

A stye typically appears as a painful, swollen bump near the edge of the eyelid.

What to do: Avoid using new or irritating skincare products, and do not squeeze, scratch, or rub the bumps.

Corticosteroid creams should only be used with medical guidance, as they can worsen periorificial dermatitis.

It is important to consult a dermatologist if the bumps do not improve, become increasingly painful, or develop pus.

If the red spots are flat, do not itch, and appear after intense coughing, vomiting, or crying, they may be petechiae, which are tiny red spots caused by broken blood vessels.

Red rash under the eyes

A red rash under the eyes is commonly caused by contact dermatitis, which occurs when the skin reacts to an irritating substance or allergen, such as makeup, fragrances, cleansers, eye drops, or nail polish transferred to the face.

In addition to redness, contact dermatitis may cause itching, dryness, swelling, burning, or peeling of the skin.

Other possible causes include atopic dermatitis (eczema), which is more common in people with a history of allergies or asthma, and seborrheic dermatitis, which causes red, flaky, or slightly oily patches that may also affect the eyebrows and scalp.

What to do: Identify and avoid products that may be triggering the rash, wash the face with a gentle, fragrance-free cleanser, and apply a moisturizer suitable for sensitive skin.

If the rash persists or worsens, a dermatologist may recommend treatment with an anti-inflammatory cream that is safe to use around the eyes.

Seek urgent medical attention if the rash is accompanied by fever, rapidly worsening swelling, significant warmth or pain around the eye, eye pain, or changes in vision, as these symptoms may indicate an infection, such as periorbital or orbital cellulitis.
