Sodium bicarbonate baths

Ichthyosis is a group of skin conditions that cause dry, scaly skin. The skin may appear thickened, rough, or cracked. It is a genetic condition which is lifelong and there is no cure, but there are treatments that help to manage symptoms and improve comfort.

Sodium bicarbonate is commonly known as baking soda. Please note, baking soda is not the same as baking powder, which has acid and a drying agent added to it.

Adding sodium bicarbonate to bath water can help:

• Soften dry, scaly skin
• Reduce itching and irritation
• Make gentle exfoliation easier after the bath
• Support the skin’s natural pH balance

It’s especially useful for people with ichthyosis, where regular bathing helps to manage skin build-up and promote comfort.

Sodium bicarbonate baths are suitable for children and adults. They are not a cure but can help ease symptoms. If you have any concerns, please speak to your Dermatology team.

You will need:

• Sodium bicarbonate.
• A clean bath with comfortably warm water.

Instructions:

1. Fill the bath with warm water. Aim for around 20-30cm deep for a child or half full for an adult.
2. Add 2-3 heaped tablespoons (30-45g) of sodium bicarbonate. For a full adult bath, you can use up to 4 tablespoons (60g).
3. Stir the water until the powder is dissolved.
4. Soak in the bath for 10 to 15 minutes.
5. Pat the skin dry gently with a soft towel.
6. Apply a moisturiser or emollient straight after the bath, while the skin is still slightly damp.

• Always use lukewarm water- hot water can dry out or irritate the skin.
• Avoid getting bath water in the eyes as it may sting. If it accidentally gets into the eyes, rinse your eyes straight away with clean, lukewarm water.
• You can use this bath daily or several times a week, depending on your skin and routine.

• There is no need to rinse the skin after bathing.
• Use fragrance free moisturisers.
• Gently lift the dead skin using a soft circular motion- comfifast mittens or debrisoft pads can help.
• Avoid rubbing the skin.
• Keep skin hydrated throughout the day.

Sodium bicarbonate is available from pharmacies, supermarkets, or online. If buying online, look for food grade or pharmaceutical grade options.

If you are at all concerned about any skin changes, please contact your Dermatology team as soon as possible.
