In October 2015, researchers reported that probiotic supplementation enhances hydration and reduces visible signs of aging in the skin. Previous research suggests that probiotic supplementation impacts skin photoaging.

In this randomized, double-blind, placebo-controlled, clinical trial, 110 women ages 41 to 59 years with dry skin and wrinkles received 2 grams of Lactobacillus plantarum powder daily or a placebo daily for 12 weeks. The researchers evaluated skin hydration, wrinkles, skin gloss, and skin elasticity at the beginning of the study and every four weeks during the study period.

At week 12, the probiotic group had a marked improvement in skin water content in the face and hands and noticeably decreased wrinkle depth. An improvement in skin gloss at week 12 also was noted in the probiotic group. At weeks four, eight, and 12, there was a significant decline in transepidermal water loss in both groups compared to the beginning of the study. The reduction in water loss was particularly notable in the face and forearm in the probiotic group at week 12. In addition, there was a 13.2% improvement in skin elasticity in subjects taking the probiotic after four weeks and a 21.7% improvement after 12 weeks compared to the placebo group.

The study authors concluded, “These findings are the preliminary confirmation of the antiaging benefit to the skin of L. plantarum HY7714 as a nutricosmetic agent.”
