### Could Applying Beneficial Bacteria to the Skin Be a Future Treatment for Eczema? Here's What Scientists Are Discovering Scientists are still trying to understand what causes atopic dermatitis (eczema), but they believe it involves genetics, the immune system, skin barrier defects, allergies, and environmental triggers. Researchers are also looking into the role of the microbiome, which includes the bacteria, fungi, and viruses living on and in our bodies. Imbalances in these microorganisms can lead to various diseases, including skin conditions like eczema. Studies have shown that people with eczema have more harmful bacteria and fewer beneficial bacteria on their skin. This led scientists to wonder if adding good bacteria to the skin could help balance things out and improve eczema symptoms. Early research has been promising. For example, a study led by Dr. Ian A. Myles used a type of bacteria called Roseomonas mucosa to treat eczema. Participants sprayed this bacteria on their skin and saw significant improvements. Another study used Staphylococcus hominis to fight off harmful bacteria like Staphylococcus aureus, which is common in eczema patients. This also showed positive results. While these treatments are still in the early stages of research, they offer hope for new, natural ways to manage eczema. More studies are needed, but the initial findings suggest that beneficial bacteria could play a crucial role in future eczema treatments.
