Several studies have shown that taking a vitamin D supplement can help ward off eczema flare-ups. As one 2015 review Trusted Source notes, vitamin D is known to improve both the immune system and skin barrier function, so it makes sense that people with a vitamin D deficiency might be more likely to experience eczema.
After reviewing numerous studies, the review concluded that more well-conducted research was needed before any conclusions could be drawn. However, based on the studies and anecdotal evidence included in the review, it’s very possible that taking a vitamin D supplement could improve your symptoms.
You may have already heard about the alleged benefits of using tea tree oil to treat eczema. While there are only a few scientific studies into the efficacy of using tea tree oil, the results are promising.
One 2004 study by Trusted Source on animals found that using 10 percent tea tree oil cream could significantly reduce itching in 10 days.
Another 2011 study by Trusted Source found that using tea tree oil topically could be an effective way to improve symptoms.
