Will phototherapy help me to cure atopic eczema flare-up at 29?

Question

Hello doctor,

I am 29 and have had atopic eczema since my teenage years, but this time the flare is different. The patches on my arms and chest are very red, dry, and have tiny blisters that sometimes leak fluid.

I recently moved to a new city with a colder climate, and since then my skin has been extremely dry despite applying moisturizer twice daily. I also started using a new body wash. Could the climate change alone worsen eczema this much, or should I suspect an irritant reaction?

I am confused about how often to bathe and which type of soap is safe. Would phototherapy be an option if creams are not helping anymore?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Eczema can worsen due to both environmental changes and irritants. Moving to a colder, drier climate can pull moisture from the skin, making it extremely dry despite regular moisturization.

At the same time, new soaps, body washes, or detergents can irritate the skin, causing redness, dryness, and fluid-filled blisters. It is likely that both climate change and a potential irritant reaction are contributing to this flare.

For bathing, it is best to keep showers short (five to ten minutes) with lukewarm water, use gentle, fragrance-free cleansers or soap substitutes, and moisturize immediately after bathing to lock in moisture.

If topical creams are not sufficient, phototherapy can be an effective treatment for moderate to severe eczema, reducing inflammation and itching over time under a dermatologist’s supervision. Identifying triggers, including new products or environmental factors, is also important to prevent further flares.

If your eczema is moderate to severe, I would suggest considering biologic therapy.

For moderate to severe eczema that does not respond well to topical treatments, biologic therapies are an effective option. These include medications like Dupilumab, which target specific immune pathways involved in eczema, helping to reduce inflammation, itching, and flare frequency.

Biologics are generally safe for long-term use under a dermatologist’s supervision and are especially useful for adults with persistent or widespread eczema.

Lifestyle modifications also play a key role in controlling flare-ups and reducing itching. Daily skincare is essential: use gentle, fragrance-free cleansers instead of harsh soaps, take short lukewarm showers rather than hot baths, and moisturize immediately after bathing to lock in hydration.

Avoid scratching as much as possible, and consider covering affected areas at night with soft cotton gloves or clothing to prevent skin damage while sleeping. Wearing loose, breathable clothing made of cotton rather than wool or synthetic fabrics can also help minimize irritation.

Identifying and avoiding triggers is equally important. Stress management through regular exercise, meditation, or relaxation techniques can reduce flare-ups, as stress can worsen eczema.

Environmental factors such as dry air or sudden temperature changes can be managed with a humidifier in dry climates and by layering clothing in cold weather.

Additionally, limiting exposure to known irritants like detergents, strong soaps, and certain chemicals at work or during hobbies can help maintain skin health. Keeping a journal of flare patterns, foods, and activities can help identify personal triggers and guide preventive strategies.

I hope this has helped you.
