What’s more, research has indicated a relationship between vitamin D and skin moisture.
A study in 83 women found that people who had low vitamin D levels had lower skin moisture than participants who had normal vitamin D levels, and as vitamin D blood levels increased, skin Moisture also increased.
This is important because people with atopic eczema often have very dry skin because their skin is unable to retain excess moisture.
This dryness can make the skin more likely to react to something triggering, causing itching and pain.
Another 12-week study in 50 women found that daily treatment with a nutritional supplement containing 600 IU of vitamin D led to significant improvement in skin hydration.
However, the supplement contained a combination of nutrients, so it is unclear whether treatment with vitamin D alone would result in the same positive outcome.
Common tips to reduce symptoms
It is important to resist scratching the affected area as it can worsen the symptoms.
Scratching usually damages the skin, which in itself can cause more eczema, the NHS warns.
You should also install your eczema trigger and take steps to avoid them.
“A GP will work with you to establish which eczema can flare up, although it may be better or worse for no apparent reason,” the NHS says.
As the health body states, once you know your triggers, you can try to avoid them.
- If some fabrics irritate your skin, avoid wearing them and stick to natural materials such as soft, fine weave fabric or cotton
- If the heat increases your eczema, keep the rooms in your house cool, especially in the bedroom
- Avoid using soap or detergents that may affect your skin – use an alternative to soap instead.
