According to Dr. Whitney Bowe, prebiotics benefit the skin in three key ways.
First, they act as a protective shield and prevent bad microorganisms from triggering an immune system reaction in the body. "This creates a more calming environment for the skin," she says.
Second, they produce natural antibiotics called antimicrobial peptides that combat bad bacteria.
And last, they boost the skin's ability to deal with external damaging factors including free radicals, sunshine and pollution.
"All of these benefits help to reduce inflammation," Dr. Bowe says. "This helps reduce flare-ups and prevents premature aging."
