Probiotic May Provide Skin Health Benefits
Skin that is too dry may become red, cracked, rough, and itchy A new study suggests that oral supplementation with heat-killed Lactiplantibacillus plantarum L-137 (HK L-137) may provide skin health benefits.
Participants in the study included 20 men and 60 women with an average age of 47. All had dry skin issues. Half were given 10 mg of HK L-137 or a placebo daily for 12 weeks. The researchers evaluated skin water content and transepidermal water loss in the forearm and face at baseline, week 4, week 8, and week 12. Participants completed The Dermatology Life Quality Index (DLQI) at baseline and at the end of the study.
Participants in the HK L-137 group saw greater increases in water content in the forearm compared to the placebo group. They also saw larger decreases of transepidermal water loss in the face and a higher increase in scores on the DLQI questionannaire compared to the placebo group.
Participants in the HK L-137 group who had the driest skin at baseline and/or were above the average age of participants saw the highest increases in water content. They also saw the largest decrease in transepidermal water loss in the face.
The study was conducted by researchers from House Wellness Foods Corp. It was published online ahead of print on July 6, 2022 in the journal Frontiers in Medicine.
