Atopic dermatitis is a common inflammatory condition that can cause itchy and irritated skin. The condition tends to develop in early childhood but may occur at any age. It can appear anywhere on the skin but most often affects the hands, insides of the elbows, backs of the knees, and the face and scalp.
AD can develop on any area of skin at any age; however, it tends to appear in specific places according to a person’s age. For example, in infants, AD is more likely to occur on the face; for young children, it often develops on the insides of the elbows, and many adults may experience AD on the hands.
This article discusses common areas where atopic dermatitis may occur and which treatments may be beneficial.

AD is the most common form of eczema, and it typically involves the face. Infants and young children with AD often present with dry, itchy, and irritated skin on their faces. This can also include the neck, scalp, and eyelids. Facial AD can also occur regularly in teens and adults experiencing a flare of AD.
Many treatments for AD are topical creams that help to retain moisture and reduce symptoms of AD. However, doctors may recommend weaker dosages when treating AD on the face to prevent side effects due to the skin being much thinner on the face. They may also suggest other options, such as topical calcineurin inhibitors, which are gentler on sensitive skin.

AD commonly appears on the limbs, particularly at the flexures, or skin creases, of the elbows and knees. This is why many people may describe AD as having a flexural distribution, as these skin folds may rub against each other during movements, such as walking, which may exacerbate symptoms.
It is also common for people to experience AD on the hands and wrists. Approximately 50–60% of people with active AD may experience AD on the hands. However, it has a higher prevalence with increasing age.
AD also develops on the lower legs, ankles, and feet.
Treatments for AD on the limbs include:
- oral medication
- topical medication
Treatment also aims to prevent potential triggers. This may include avoiding potential irritants, such as soaps and fragrances, minimizing exposure to chemicals, and wearing gloves at work and home.
The National Eczema Association suggests applying wet wraps to the limbs. This involves wrapping the skin in wet gauze to help retain moisture.

Some people experience AD on their torso, chest, and stomach. Typically, doctors will prescribe the same treatments as they would for AD on other parts of the body and include oral and topical medications, moisturizers, or phototherapy.
Some people may require assistance when applying topical medications to their back.
Taking lukewarm baths may be a useful home remedy for people with AD in these areas as they can comfortably submerge these areas in soothing water.
There is currently still some uncertainty about the exact cause of AD. However, growing
Research suggests that several genes may be involved in the development of AD. A
Many potential triggers within the environment may exacerbate symptoms of AD. Exposure to various factors, including pollutants, such as tobacco smoke, climate factors, such as temperature, and social factors, such as stress, may contribute to the development of AD.
Due to problems with the leakiness of the skin barrier and bacteria on the skin, people with AD are
Living with eczema can also adversely affect a person’s mental health — individuals may worry about their appearance or experience bullying or discrimination. Flare ups may also have links to other issues in some cases, such as:
- other conditions within the atopic march, such as asthma or hay fever
- other forms of dermatitis
- difficulty sleeping from itching
- scales or areas of hard skin that form from scratching one spot over long periods
Anyone uncertain about their symptoms or their child’s symptoms should see a doctor. Even with a previous AD diagnosis, if a person notices that symptoms get worse or flare ups seem more regular, it is advisable to talk with a doctor.
Doctors may help identify triggers by ordering allergy tests and can help suggest over-the-counter or prescription drugs to control flare ups.
Additionally, anyone noticing signs of, or suspects a skin infection, should see their doctor.
