Is it ‘just a rash’? Winter baby skin concerns, decoded
Your expert guide to common baby skin reactions in winter.
In winter, cold outdoor air and dry, heated indoor air can strip moisture from baby’s skin, breaking down the delicate skin barrier. Many reactions are ‘just a rash’, caused by simple dryness or irritation. However, some can be caused by a specific condition such as dermatitis, or by a virus, or become infected and cause severe discomfort. Spot the difference – and help baby find relief.
Simple winter dryness (xerosis)
Spot it: Rough, scaley or flaky skin patches on the arms, legs or face.
Just a rash? Yes, caused by loss of moisture, says Dr Imraan Jhetam, a specialist dermatologist with rooms in Umhlanga and Ballito.
Treat it: Apply a thick, fragrance-free, petrolatum (petroleum jelly)-based moisturiser or ointment two or three times a day, especially after a bath, to lock in moisture, he says. “Look for products that contain ingredients like cetomacrogol, ceramides, hyaluronic acid, oat extract or dexpanthenol.”
Red cheeks
Spot it: Rosy cheeks may look healthy and kissable but can signal irritation from cold air, especially on windy days which worsen dryness, causing rawness and peeling.
Just a rash? Yes, from moisture loss.
Treat it: Apply thick, fragrance-free moisturiser before and after going outdoors, says Dr Jhetam. If outdoors often, consider getting a plastic stroller cover.
Chapped lips
Spot it: Dry, flaky, red or cracked lips, often with a pink/brown, scaly ring around the mouth where there has been drool. In severe cases, skin may crack and bleed.
Just a rash? Yes, caused by cold air and the wetness from drool breaking down the skin barrier.
Treat it: Apply a gentle lip balm with baby-safe ingredients, such as petroleum jelly or lanolin before going outside and before feeds, to protect against drool. “When breastfeeding a newborn, applying a little breastmilk may be enough,” Dr Jhetam says.
Atopic dermatitis (eczema)
Spot it: Patches of dry, scaly, itchy red or purplish skin in folds (inside elbows, behind knees), and on the cheeks and forehead, which can become weepy or crusty.
Just a rash? No, this is a chronic, non-infectious inflammatory skin condition caused by a combination of genetics, immune system dysfunction, and environmental factors, Dr Jhetam says. It can worsen dramatically in winter and constant itchiness causes discomfort and affects sleep.
Treat it: Use a mild fragrance-free, hypoallergenic cleanser rather than soap, then apply thick moisturising ointments for sensitive skin. “For severe eczema, your healthcare provider may recommend enhanced moisturiser or topical treatments such as cortisone or non-cortisone creams,” he says. Keep baby’s fingernails short to prevent scratching or cover them with cotton mittens.
Contact dermatitis
Spot it: Red, itchy, sometimes painful rash featuring dry, flaky, scaly patches or small blisters, and causing burning and stinging. It appears in localised areas where the skin has touched an irritant, such as a wool sweater, synthetic fibres and rough textures, or specific allergens in the likes of scented wipes, washing detergents or fabric softeners.
Just a rash? No – a reaction to an external irritant or allergen.
Treat it: Identify the irritant so you can avoid it. “Wash baby’s skin with mild, hypoallergenic cleanser or plain water, then apply fragrance-free moisturiser or barrier cream,” says Dr Jhetam.
Viral rashes (viral exanthem)
Spot it: Spots, blotches or blisters on the face and torso, often accompanied by fever, irritability or cold symptoms.
Just a rash? No, the cause is a viral infection such as measles, roseola or chicken pox, he says.
Treat it: These rashes usually resolve on their own. Manage fever or pain with acetaminophen or ibuprofen if baby is over six months. “For younger babies consult your healthcare professional, especially if they have very high fevers, difficulty breathing or signs of dehydration (fewer nappies, lethargy, irritability, excessive sleepiness).”
Winter heat rash (‘prickly heat’)
Spot it: Tiny red or pink bumps, often in skin folds or on the neck or back, due to blocked sweat ducts.
Just a rash? Yes, caused by overheating, mostly from wearing too many layers, especially of synthetic fabrics which trap moisture, causing irritation.
Treat it: Cool the skin with damp compresses, then apply a soothing gel like pure aloe vera, says Dr Jhetam. “Dress baby in layers of breathable cotton or bamboo clothing, and with fever, dress them lightly with a vest”.
Know when to get help
Consult your healthcare professional if baby’s rash shows no improvement after 1-2 weeks of consistent moisturising, or they show signs of infection – fever, or skin that oozes, crusts and is warm to the touch and causes pain or irritation. You may be referred to a dermatologist.
How to prevent winter rashes
To protect baby’s skin in winter and help keep rashes at bay:
• Shorten baths to under 10 minutes and use lukewarm (not hot) water.
• Pat skin dry (don’t rub) and immediately apply baby-friendly moisturising ointment.
• Invest in a humidifier to add moisture back into dry indoor air.
• Choose natural fabrics next to the skin, avoiding any that may irritate (such as wool).
• Use fragrance-free laundry detergents, skip fabric softeners, and double rinse winter items.
