Introduction
Cold air holds less moisture; indoor heating drops humidity further. Together they increase transepidermal water loss and weaken the skin barrier—so xerosis (dry skin), eczema flares, and irritant hand dermatitis spike from late fall through early spring in Ottawa. Authoritative patient education on atopic dermatitis and dry skin is available from the American Academy of Dermatology eczema resource center and the Canadian Dermatology Association; sun protection basics year-round are summarized by Health Canada.
Why winter stresses skin
Environment
- Outdoor cold + wind — Increases evaporation and mechanical irritation on exposed cheeks and hands
- Indoor heat — Low relative humidity impairs barrier repair overnight
- Long hot showers — Strip intercellular lipids; shorten showers and lower temperature
Common clinical patterns
- Xerotic eczema — Itchy, flaky patches on shins and flanks
- Atopic dermatitis flares — Often need prescription anti-inflammatory therapy when emollients fail
- Irritant hand dermatitis — Frequent washing and sanitizer without barrier repair
- Seborrheic dermatitis — Can worsen with stress and seasonal change
- Photosensitivity reminder — Snow reflects UV; winter sports raise cumulative dose
Evidence-informed home care
Moisturize on strategy
Prefer ointments or thick creams (higher oil) over thin lotions for body; products containing ceramides support barrier repair. Apply within minutes after pat-drying. For itchy inflamed areas, over-the-counter hydrocortisone for short periods may help—stop and seek care if spreading, oozing, or infected.
Gentle cleansing
Syndet bars or fragrance-free cream cleansers; avoid vigorous scrubbing. Pat dry.
Sun protection
Broad-spectrum SPF 30+ on exposed face, ears, and hands; lip balm with SPF. Reapply during prolonged outdoor activity. See AAD sunscreen FAQs for practical tips.
Clothing and humidity
Gloves for wet cold work; breathable base layers; bedroom humidifier if tolerated (clean per manufacturer to avoid mold).
When to see a clinician
Book medical assessment for sleep-disrupting itch, widespread rash, fever with rash, pus, honey crusting, or a new or changing mole—skin cancer screening is not seasonal. Psoriasis or eczema uncontrolled on emollients ± mild steroids warrants prescription therapy.
Conclusion
Winter skin care combines barrier repair, UV caution, and early escalation when inflammation escapes home management. At Trita Medical Clinic, we align advice with dermatology references and your skin type. Schedule a visit if symptoms persist beyond simple measures.
