Could a common sleep supplement also soothe eczema symptoms? New research suggests melatonin, widely used for insomnia, may play a surprising role in managing atopic dermatitis—a chronic skin condition marked by relentless itching, redness, and inflammation.
The Science Behind the Findings
A study published in the Journal of Allergy and Clinical Immunology found that melatonin improved eczema symptoms in lab mice by altering their skin bacteria. Researchers observed a reduction in harmful bacteria (Staphylococcus aureus) and an increase in protective bacteria (Staphylococcus epidermidis), along with higher levels of propionic acid, a compound that fights skin inflammation.
From Mice to Humans: The Big Question
While the results are promising, experts caution that animal studies don’t always translate to humans. Dermatologists emphasize the need for clinical trials to confirm whether melatonin can similarly rebalance skin bacteria in people with eczema.
Better Sleep, Fewer Flare-Ups
Even if melatonin’s direct impact on eczema remains unproven, it already offers a proven benefit: better sleep. Since poor sleep worsens itching and inflammation, improving rest could help break the vicious itch-scratch cycle—a major relief for sufferers.
A Supplemental Solution, Not a Cure
Doctors stress that melatonin should complement—not replace—traditional eczema treatments like moisturizers and anti-inflammatory creams. But if future studies confirm its skin benefits, this affordable, over-the-counter supplement could become a valuable addition to eczema care.
The Takeaway
For now, melatonin may help eczema patients in two ways: by promoting restful sleep and, potentially, by calming inflamed skin. As research continues, this familiar sleep aid could emerge as an unexpected ally in the fight against eczema.
