As the air cools and humidity drops, many people with eczema (atopic dermatitis) or psoriasis start to notice their skin acting up again — dry patches, itching, redness, or flaking that seemed manageable during the summer can suddenly return. At Borealis Dermatology, we see a clear rise in these flare-ups every fall. The good news? With the right care and early intervention, you can stay ahead of the season’s skin challenges.
Q: Why do eczema and psoriasis tend to worsen in cooler months?
A: The biggest culprit is dry air. When outdoor humidity drops and indoor heating turns on, the moisture in your skin evaporates faster. This weakens the skin barrier, making it easier for irritants and allergens to trigger inflammation.
For people with eczema, this means more itching, dryness, and cracking, while those with psoriasis may notice new plaques, redness, and flaking. Other seasonal factors also play a role:
- Heavier clothing: Wool or synthetic fabrics can irritate sensitive skin.
- Hot showers: Though tempting in cold weather, hot water strips skin of protective oils.
- Less sunlight: UV exposure in moderation helps control psoriasis, so shorter days can trigger a rebound in symptoms.
- Stress and routine changes: The back-to-school and holiday season can increase stress, which is a known trigger for both eczema and psoriasis flare-ups.
Q: How can moisture retention help prevent flare-ups?
A: Moisture is your skin’s best defense. A consistent moisturizing routine helps repair the skin barrier, reduce itching, and prevent cracking or flaking.
Here’s how to do it right:
Choose a thick, fragrance-free moisturizer or ointment.
Look for ingredients like ceramides, glycerin, shea butter, or petrolatum.
Apply within three minutes of bathing.
Pat skin dry and lock in moisture immediately — timing matters!
Use a humidifier indoors.
Restoring moisture to the air can help skin retain hydration overnight.
Reapply throughout the day.
Areas like hands, elbows, and knees may need extra care during colder months.
At Borealis Dermatology, we often recommend specific barrier repair creams and can tailor moisturizer choices based on your skin’s condition and sensitivity level.
Q: What role do topical steroids play in managing eczema and psoriasis?
A: Topical corticosteroids are a mainstay treatment for both eczema and psoriasis flare-ups. They work by reducing inflammation and calming the immune response in affected skin.
For mild to moderate symptoms, low- to mid-strength steroids can control redness and itching when used properly. For more stubborn patches, stronger formulations or combination treatments may be prescribed.
However, it’s important not to overuse or abruptly stop topical steroids without guidance — doing so can lead to rebound symptoms. Dermatologists at Borealis Dermatology carefully adjust strength, frequency, and duration to ensure both safety and effectiveness.
For patients who cannot tolerate steroids or need long-term control, non-steroidal options like topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus) or topical PDE4 inhibitors can also be considered.
Q: When are biologic treatments appropriate?
A: For moderate to severe eczema or psoriasis that doesn’t respond to topical treatments alone, biologic therapies can be life-changing.
Biologics target specific parts of the immune system that drive inflammation — offering more precise control than traditional systemic medications. These treatments are typically given as injections and have been shown to dramatically reduce symptoms and improve quality of life.
At Borealis Dermatology, we evaluate each patient’s medical history, lifestyle, and disease severity to determine if a biologic therapy is appropriate and safe.
Q: What at-home habits can help reduce flare-ups this fall?
A: Small lifestyle adjustments can make a big difference. Try incorporating these dermatologist-approved habits:
- Short, lukewarm showers only. Avoid long, hot showers.
- Switch to gentle, fragrance-free cleansers. Avoid soaps with alcohol or dyes.
- Layer clothing wisely. Stick to breathable cotton; avoid scratchy fabrics.
- Moisturize twice daily, even on “good” days. Prevention is key.
- Manage stress and get adequate rest. Stress hormones can worsen inflammation.
- Schedule regular check-ins with your dermatologist. Early intervention keeps flare-ups from escalating.
Q: When should you see a dermatologist?
A: If your skin becomes extremely dry, painful, or itchy despite over-the-counter care — or if you notice new patches, cracks, or bleeding — it’s time to schedule an appointment. Professional care can help you regain comfort, prevent infection, and avoid scarring.
A dermatologist can assess whether your current regimen is strong enough or if prescription treatments or biologics are warranted.
