The term probiotic is defined as “living microorganisms, which, when consumed in adequate amounts, confer a health effect on the host.” The most commonly used probiotics in humans and animals are enterococci, lactobacilli and bifidobacteria, which are natural residents of the intestinal tract.
Currently, finding alternatives to antibiotics for skin treatment is receiving a lot of interest in research. It has been found that, similarly to the gut microflora, the skin’s microbiota plays a beneficial role. Thus, the possibility to modulate the microbiota more selectively is highly interesting.
UV exposure is known to negatively affect immune system functions. Clinical studies suggest that certain probiotics can actually help preserve the skin’s homeostasis by modulating the skin’s immune system. Furthermore, ongoing research has shown that a diet/supplement regimen rich in probiotics is linked to reduced acute allergic skin responses.
