PROBIOTICS FOR YOUR SKIN
The “good” bacteria that live in our guts are also at home on—and good for— our skin, helping maintain its equilibrium so it doesn’t become irritated or overly oily or dry. “Applied topically in skincare treatments, certain probiotic strains have been shown to help reduce inflammation. Further research is needed to pinpoint which ones can fight acne and flare-ups caused by rosacea,” says Birnur Aral, Ph.D., Good Housekeeping Institute Beauty Lab director. For maximum efficacy, look for probiotics in treatment products such as serums and moisturizers rather than those that are rinsed off, like cleansers and masks, so the ingredients will stay on your skin.
