Vitamin D Supplements
Various studies show that taking vitamin D supplements regularly make you less susceptible to eczema flare-ups. A 2015 study showed that vitamin D helps boost the immune system and protects the skin from infections. Vitamin D deficiency weakens the skin barrier and makes you more susceptible to eczema,
The studies on the effects of vitamin D on eczema are not conclusive. However, anecdotal studies show that vitamin D supplements [1] can help treat the symptoms of eczema.
Sunflower Oil
Sunflower oil is produced from sunflower seeds. Studies show that it protects the outer layers of the skin from bacteria and prevents the skin from getting dry. Sunflower oil also helps prevent dehydration [2] of the skin, and treat inflammation and itching. Sunflower should be added directly to the skin a few minutes after bathing when the skin is still damp.
