Atopic dermatitis (AD), often called eczema, is a chronic inflammatory skin condition that causes itching, dryness, and skin inflammation. While the condition affects people of all backgrounds, research shows that Black, Indigenous, and People of Color (BIPOC) may experience unique challenges related to diagnosis, symptom presentation, and access to care.

Understanding these differences is important for improving treatment, awareness, and research participation.

How Atopic Dermatitis Appears on Different Skin Tones

One challenge in diagnosing atopic dermatitis in BIPOC patients is that symptoms may appear differently on darker skin tones.

Many medical textbooks historically showed eczema primarily on lighter skin, where inflammation often appears red or pink. However, on darker skin tones, eczema may look different, including:

• Purple, gray, or dark brown patches instead of red
• Thickened skin (lichenification) from chronic scratching
• Small raised bumps known as papular eczema
• Changes in skin pigmentation after flare-ups

Because these visual differences have not always been widely taught, some patients with darker skin may experience delayed diagnosis or misdiagnosis.

Higher Burden of Disease in Some Communities

Studies suggest that Black children in the United States are more likely to develop atopic dermatitis and may experience more severe disease compared with some other populations.

Several factors may contribute to this, including:

• Genetic differences in skin barrier function
• Environmental exposures
• Differences in access to dermatology care
• Social and economic factors that affect healthcare access

While researchers are still studying the exact causes, it is clear that the burden of disease can be significant.

Post-Inflammatory Pigmentation Changes

Another important issue for many patients with darker skin tones is post-inflammatory hyperpigmentation (PIH) or hypopigmentation after eczema flares.

When inflammation heals, the skin may become darker or lighter than the surrounding area. These pigmentation changes can last for months and may cause emotional distress or concerns about appearance.

For some patients, these changes can be just as frustrating as the eczema itself.

Why Representation in Clinical Research Matters

Historically, BIPOC populations have been underrepresented in many clinical trials. When diverse populations are not included in research, it can limit understanding of how treatments perform across different skin types and communities.

Increasing diversity in clinical trials helps researchers:

• Understand how treatments work in different populations
• Identify differences in symptom presentation
• Improve treatment guidelines for all patients
• Ensure new therapies are effective across diverse groups

Greater representation ultimately helps make medical research more inclusive and more accurate.

Moving Toward More Inclusive Care

Today, there is growing recognition of the importance of diversity in dermatology and clinical research. Efforts are underway to improve medical education, increase representation in clinical trials, and expand access to dermatologic care.

For people living with atopic dermatitis, these changes are helping move the field toward more personalized and equitable care for patients of all backgrounds.

Dupilumab has become an important treatment option for many people living with moderate-to-severe atopic dermatitis (AD). By targeting specific immune pathways involved in inflammation, it has helped many patients experience meaningful improvements in itching and skin symptoms.

However, not everyone responds to dupilumab in the same way. Some patients may experience only partial relief, while others may not see significant improvement at all.

Understanding why this happens is an active area of research.

Atopic Dermatitis Is a Complex Disease

One reason some patients may not respond to dupilumab is that atopic dermatitis is not the same for everyone. The condition is driven by a combination of factors, including:

• Immune system activity
• Genetics
• Skin barrier dysfunction
• Environmental triggers

Dupilumab works by blocking the IL-4 and IL-13 pathways, which are key drivers of inflammation in many patients. However, in some individuals, other inflammatory pathways may also play a role.

If those pathways are the primary drivers of disease, blocking IL-4 and IL-13 alone may not fully control symptoms.

Differences in Immune System Activity

Atopic dermatitis involves a complex network of immune signals. Some patients may have stronger involvement of additional immune pathways such as:

• IL-31 (associated with itch signaling)
• IL-22 (linked to skin thickening)
• Other inflammatory cytokines

When these pathways are active, a treatment targeting only IL-4 and IL-13 may not provide complete relief.

Severity and Disease History

Patients with long-standing or more severe disease may also have skin changes that are harder to reverse quickly. Chronic inflammation can lead to thickened skin, deeper lesions, and persistent itching that may require combination treatment approaches.

Even when dupilumab reduces inflammation, it may take time for the skin to fully heal.

Individual Differences in Treatment Response

As with many medications, individuals respond differently due to variations in genetics, immune system behavior, and metabolism. These differences can influence how well a treatment works for a particular person.

Researchers are continuing to study these variations in order to better understand which patients are most likely to benefit from specific therapies.

New Treatments Are Being Studied

Because not all patients respond to dupilumab, researchers are exploring additional treatment options that target other inflammatory pathways involved in atopic dermatitis.

These include:

• New biologic medications
• Targeted immune therapies
• Novel oral treatments designed to reduce inflammation and itching

Clinical trials play a critical role in evaluating these potential therapies and expanding treatment options for patients.

Expanding Options for Patients

The growing understanding of atopic dermatitis has led to significant advances in treatment over the past decade. While dupilumab has been an important breakthrough, continued research is helping scientists develop additional therapies for patients who need alternative options.

For individuals living with moderate-to-severe eczema, these advances offer hope for more personalized and effective treatment approaches in the future.

For many people living with moderate-to-severe atopic dermatitis (AD), managing symptoms can be challenging. Persistent itching, inflammation, and skin irritation often continue despite topical creams or oral medications. In recent years, newer treatments such as biologic therapies have provided additional options for patients whose symptoms remain difficult to control.

One of the most well-known biologic treatments for atopic dermatitis is dupilumab.

What Is Dupilumab?

Dupilumab is a prescription biologic medication used to treat moderate-to-severe atopic dermatitis in patients whose symptoms are not well controlled with topical therapies alone.

Unlike traditional treatments that broadly suppress the immune system, dupilumab works by targeting specific pathways involved in inflammation. It blocks signals from two proteins in the immune system called interleukin-4 (IL-4) and interleukin-13 (IL-13). These proteins play an important role in the inflammatory response associated with eczema.

By interrupting these signals, dupilumab can help reduce inflammation, itching, and skin damage.

How Dupilumab Is Taken

Dupilumab is administered as an injection under the skin (subcutaneous injection). After an initial loading dose, most patients receive injections every two weeks.

Depending on the treatment plan, injections may be given in a medical office or self-administered at home after proper training.

What Symptoms Dupilumab May Improve

Many patients who take dupilumab experience improvements in several symptoms of atopic dermatitis, including:

• Reduced itching
• Decreased redness and inflammation
• Healing of damaged skin
• Fewer eczema flare-ups
• Improved sleep and quality of life

Because severe itching can significantly affect daily life, even moderate reductions in itch can make a meaningful difference for patients.

Possible Side Effects

Like any medication, dupilumab may cause side effects in some people. Commonly reported side effects include:

• Injection site reactions
• Eye irritation or conjunctivitis
• Dry eyes
• Cold sore outbreaks

Most side effects are manageable, but patients should discuss any new symptoms with their healthcare provider.

Not a Cure for Atopic Dermatitis

While dupilumab has helped many people better manage moderate-to-severe eczema, it is not a cure. Symptoms may return if treatment is stopped, and some patients may continue to experience flare-ups even while taking the medication.

Additionally, not every patient responds to dupilumab in the same way. Some individuals may experience only partial improvement, while others may not see significant changes.

Ongoing Research in Atopic Dermatitis

Researchers continue to study new therapies for atopic dermatitis, including treatments designed for patients who do not respond well to currently available medications.

Clinical trials play an important role in developing these new treatment options and improving our understanding of this complex skin condition.

If you live with moderate-to-severe atopic dermatitis and current treatments aren’t providing enough relief, you may be wondering about other options. Clinical trials are one way patients can access investigational therapies while contributing to medical research.

Talking to your doctor about clinical trials may feel intimidating at first, but having an open conversation can help you understand whether research participation could be a good fit.

What Are Clinical Trials?

Clinical trials are carefully designed research studies that evaluate new medications, treatments, or approaches to managing diseases. These studies are conducted under strict safety and ethical guidelines and are monitored by medical professionals and regulatory agencies.

For atopic dermatitis, clinical trials may investigate:

• New biologic medications
• Novel immune-targeting therapies
• Improved topical treatments
• Innovative approaches to reducing inflammation and itching

The goal is to determine whether these investigational treatments are safe and effective.

Preparing for the Conversation

Atopic dermatitis (AD), often referred to as eczema, is a chronic inflammatory skin condition that causes dry, itchy, and inflamed skin. While many people experience mild eczema at some point in their lives, moderate-to-severe atopic dermatitis can significantly affect daily comfort, sleep, and quality of life.

What Is Atopic Dermatitis?

Atopic dermatitis is a condition related to immune system dysfunction and a weakened skin barrier. In people with AD, the skin struggles to retain moisture and protect against irritants, allergens, and bacteria. This leads to inflammation, dryness, and intense itching.

The condition often begins in childhood but can continue into adulthood or even start later in life. It tends to flare up periodically, with symptoms worsening during certain triggers such as stress, weather changes, irritants, or allergens.

Symptoms of Moderate-to-Severe Atopic Dermatitis

While mild eczema may cause occasional dryness or itching, moderate-to-severe atopic dermatitis often involves more persistent and widespread symptoms, including:

• Intense itching that can disrupt sleep
• Red, inflamed, or darkened patches of skin
• Thickened or leathery skin from repeated scratching
• Cracked or oozing skin lesions
• Dry, scaly patches that may cover larger areas of the body
• Increased risk of skin infections

The itch associated with AD can be particularly challenging. Many patients describe an “itch-scratch cycle,” where scratching worsens inflammation, which then leads to more itching.

How It Affects Daily Life

Moderate-to-severe atopic dermatitis can impact more than just the skin. People living with the condition often report:

• Difficulty sleeping due to itching
• Reduced concentration or productivity
• Emotional stress or frustration
• Avoidance of certain clothing, environments, or activities

Because symptoms can be unpredictable and visible, AD may also affect confidence and social interactions.

Current Treatment Options

Treatment for moderate-to-severe atopic dermatitis often involves a combination of approaches aimed at reducing inflammation, relieving itching, and repairing the skin barrier. These may include:

• Prescription topical medications such as corticosteroids or calcineurin inhibitors
• Oral medications that suppress immune system activity
• Injectable biologic therapies targeting specific inflammatory pathways
• Moisturizers and barrier repair creams
• Lifestyle adjustments to avoid triggers

However, not all patients respond well to available treatments. For some individuals, symptoms continue despite trying multiple therapies.

The Role of Clinical Research

Clinical trials play an important role in developing new treatments for moderate-to-severe atopic dermatitis. Researchers are studying innovative therapies designed to target the underlying immune pathways involved in eczema.

These studies help scientists better understand the disease and evaluate potential new medications that may offer improved symptom control.

For patients who continue to struggle with symptoms, clinical research may offer access to investigational treatments while helping advance medical knowledge for others living with the condition.
