Managing ichthyosis as the weather turns colder can be more challenging due to the cold, dry air, which can worsen symptoms and exacerbate skin dryness, flakiness, and cracking. Cold weather tends to strip the skin of moisture anyway, which is already impaired in people with ichthyosis, making moisturising and protective care even more crucial. Here are some strategies for managing ichthyosis in winter:

1. Moisturise Frequently and Heavily

• Thicker moisturisers: Use thicker, more emollient creams or ointments that provide a protective barrier to prevent moisture loss. Look for products with ingredients like petrolatum (Vaseline), lanolin, urea, or ceramides. Be aware of any ingredients you may be sensitive to.
• Apply immediately after bathing: To lock in moisture, apply moisturiser while the skin is still damp from a bath or shower.
• Consider occlusive treatments: For very dry or cracked areas, you may need to apply an occlusive layer (such as an ointment) to seal in moisture and prevent it from evaporating.
• Wear glove and socks in bed: If you can, heavily moisturise hands and feet at bedtime and wear gloves and thick socks over your emollient.

2. Hydrate Your Skin with Humidity

• Humidifiers: Use a humidifier in your home to prevent the air from becoming too dry, which can further strip moisture from the skin.
• Avoid direct heat: While heaters can make rooms warm, they can also make the air extremely dry. Keep the heat on lower settings where possible and maintain humidity in the room.

3. Gentle Cleansing Routine

• Avoid hot showers and baths: Hot water can exacerbate dryness and irritation, so opt for lukewarm water when bathing.
• Gentle cleansers: Choose fragrance-free, soap-free cleansers that do not strip the skin of its natural oils. Harsh soaps can make ichthyosis worse by drying the skin further.
• Limit bath time: Prolonged exposure to water can dry out the skin, so try to limit the time spent in the bath or shower.

4. Exfoliate Carefully

• Gentle exfoliation: Some forms of ichthyosis can benefit from mild exfoliation to remove excess dead skin. However, avoid harsh scrubs, which can irritate the skin. Instead, use a soft washcloth, exfoliating mitt, or gentle chemical exfoliants (keratolytics) like those containing urea, lactic acid or salicylic acid. You could try a handful of bicarbonate of soda in the bath to help soften the skin before gently exfoliating. 
• Use exfoliating treatments sparingly: Over-exfoliating can worsen dryness and cause irritation, so limit this step to once or twice a week.

5. Protect the Skin from the Elements

• Dress in layers: During winter, wear soft, breathable layers to prevent itching from rough fabrics. Avoid wool and opt for cotton or silk to reduce irritation.
• Cover exposed skin: In very cold weather, make sure to cover the skin with scarves, gloves, and hats to protect against the wind and cold air.
• Use protective balms: On exposed areas such as lips, hands, and face, consider applying a protective balm or barrier cream to shield against the cold.

6. Maintain a Healthy Diet and Hydration

• Drink plenty of water: Stay hydrated from the inside out by drinking enough fluids, as dehydration can worsen skin dryness.
• Maintain a balanced diet: Ensure your diet includes sufficient amounts of essential fatty acids, vitamins, and minerals to support skin health. Omega-3 fatty acids, found in foods like fish and flaxseed, can help improve skin hydration.

Summary of Key Differences in Winter:

• Cold, dry air exacerbates skin dryness, leading to increased scaling and flaking.
• Indoor heating can dry out the skin further.
• Moisturising and protecting the skin becomes even more crucial, with emphasis on using thicker, heavier products.
• Humidification in the home and protecting the skin from harsh elements is essential.

By adopting these strategies, you can help manage ichthyosis more effectively during the winter months. The key is to keep the skin well-moisturised, protected from the elements, and free from irritants.
