Many microorganisms – bacteria, fungi and virus – live. They protect skin immunity and protect them from diseases. A new study showed that some bacteria, such as Staphylococcus epidermidis, can neutralize the damage from UV rays.
Scientists examined how the skin of mice reacted to UVB radiation. When exposed to sunlight in the skin, it is formed by a cis-urocanic acid substance that can suppress immune protection and cause inflammation. This makes the skin vulnerable to diseases, including cancer.
However, some skin bacteria can divide this substance using a special enzyme – lesson. This helps to protect the skin and even use harmful molecules as a power supply.
Researchers hope that these data will not only protect them from the sun, but also will help create new creams that restore the skin after damage.
