Probiotics better than Botox?

New research suggests probiotics may help young, healthy women retain smooth skin.

Probiotics in dairy may help young women keep their milky-smooth complexions. Why Japanese scientists researched this demographic, rather than targeting wrinkly, older women who may truly need any potential probiotic skin-smoothing power is not clear, but the study has been published in the Journal of Dairy Science. It was noted on

"Although many reports have addressed the effect of lactic acid bacteria on skin properties in subjects with skin diseases, such as atopic dermatitis, few studies have involved healthy humans," lead investigator Hiromi Kimoto-Nira, PhD, of the National Agriculture and Food Research Organization (NARO) Institute of Livestock and Grassland Science (NILGS), Tsukuba, Japan, said in a release.

For the randomized, double-blind trial, researchers gave 23 healthy young women between the ages of 19 and 21 either milk fermented with Lactococcus lactis strain H61 or conventional yogurt each day for four weeks. Researchers took blood samples at the beginning and end of the trial and measured the skin hydration (inner forearms and cheek) and melanin content, elasticity and sebum (the substance that keeps skin from drying out) content of the women’s skin.

After four weeks, skin hydration among all women in the study was higher. The sebum content of the cheeks of the women who consumed the probiotic yogurt, however, rose significantly while the levels of the women who ate the conventional yogurt did not. Perhaps the fountain of youth is teeming with probiotics?
