Can Eczema Start in Later Life?
Eczema, medically known as dermatitis, is a chronic inflammatory skin condition characterized by dry, itchy, and irritated patches of skin. While many assume it's a condition exclusively for children, it can and does appear for the first time in later life. This is often referred to as 'adult-onset eczema.' According to research cited by the American Academy of Dermatology, a peak time for developing adult-onset eczema is in your 50s and beyond, challenging the long-held misconception. In fact, approximately one-third of adult cases represent new-onset eczema, demonstrating that age is not a protective factor.
Why Does Eczema Occur in Older Adults?
Several factors associated with the natural aging process make seniors more susceptible to developing eczema or experiencing a recurrence of childhood eczema. The underlying reasons include:
Weakened Skin Barrier
As we age, our skin naturally becomes thinner, drier, and less elastic. The skin barrier, which is responsible for keeping moisture in and irritants out, weakens over time. This makes it easier for environmental triggers, allergens, and other irritants to penetrate the skin and provoke an inflammatory response, leading to eczema. A key protein in the skin barrier, filaggrin, is often found at lower levels in people with eczema, and its function can deteriorate with age.
Compromised Circulation
Poor blood circulation, a condition known as venous insufficiency, is more common in seniors and can contribute to a specific type of eczema called stasis dermatitis. It affects the lower legs, where blood flow is weakest, causing skin irritation, swelling, redness, and fragility. In severe cases, this can lead to ulcers.
Reduced Immune Function
The immune system naturally changes with age, a process known as immunosenescence. This can lead to an overactive immune response to otherwise harmless environmental insults, fueling the inflammatory cascade that results in eczema symptoms.
Environmental and Lifestyle Triggers
Certain factors that might have been manageable in youth can trigger eczema in later life. These include:
- Dry air, especially with indoor heating during winter.
- Stressful life events, such as bereavement or job loss.
- Exposure to harsh chemicals in soaps, detergents, and cleaning products.
- Certain medications, including some for arthritis or cancer, can cause drug-induced eczema.
Comparison of Eczema in Younger vs. Older Adults
| Feature | Eczema in Younger Adults | Eczema in Older Adults |
|---|---|---|
| Primary Cause | Often genetic predisposition, strong immune response | Combination of aging factors (dry skin, weakened barrier, poor circulation) and genetics |
| Common Location | Elbow creases, back of knees, face, neck | Often more widespread on arms, legs, and torso; specific types like stasis dermatitis on lower legs |
| Severity | Can vary widely, often less severe overall | Tends to be more severe and persistent, with more intense itching |
| Associated Risks | Higher risk for asthma and hay fever | Increased risk for depression, anxiety, dementia, heart disease |
| Treatment Challenges | Fewer comorbidities and medications to consider | Complex management due to multiple health conditions and polypharmacy |
Managing Eczema at 70 and Beyond
Management of eczema in older adults requires a careful and comprehensive approach, often involving a dermatologist to create a tailored treatment plan.
Skincare Routine
A gentle and consistent skincare routine is paramount for healthy aging skin.
- Moisturize Regularly: Apply thick, fragrance-free creams or ointments, especially immediately after bathing, to lock in moisture. Look for products containing ceramides or hyaluronic acid.
- Use Gentle Cleansers: Avoid harsh, scented soaps that can strip the skin of its natural oils. Opt for mild, pH-balanced cleansers.
- Lukewarm Baths: Take short, lukewarm showers or baths instead of hot ones, which can dry out the skin. Consider adding colloidal oatmeal to baths for extra soothing benefits.
Medical Treatments
- Topical Medications: A healthcare provider may prescribe topical corticosteroids or calcineurin inhibitors to reduce inflammation and itching.
- Light Therapy (Phototherapy): For moderate to severe cases, controlled exposure to ultraviolet (UV) light can help reduce inflammation.
- Oral Medications: In severe cases, oral medications like immunosuppressants may be considered, though careful monitoring is needed due to potential side effects. Newer biologic medications are also an option.
Lifestyle Modifications
- Avoid Triggers: Identify and minimize exposure to triggers like certain fabrics (wool), dust mites, and chemical irritants.
- Manage Stress: Stress can exacerbate eczema symptoms. Techniques like mindfulness, meditation, and deep breathing can help.
- Stay Active: For those with stasis dermatitis, regular, gentle movement and elevating the legs can help improve circulation.
- Use Humidifiers: Especially in dry winter months, using a humidifier can add moisture back into the air and help prevent skin dryness.

Final Thoughts: A Proactive Approach
Dealing with eczema at any age is challenging, but with the unique vulnerabilities of aging skin, a proactive strategy is essential. By understanding the specific types of eczema that affect older adults and employing targeted skincare, medication, and lifestyle adjustments, seniors can effectively manage their symptoms. Regular consultation with a dermatologist is crucial for an accurate diagnosis and a personalized treatment plan, ensuring a better quality of life despite this chronic condition.
