It can also inhibit melanin biosynthesis. In the present study, we investigated the skin\u2010whitening effect of this strain by arranging an 8\u2010week clinical trial with 22 participants. PMC48 was applied to each participant's artificially UV\u2010induced tanned skin in the clinical trial.

The color intensity of the tanned skin was decreased by 47.647%, and skin brightness was increased by 8.098% after the treatment period. PMC48 also significantly decreased the melanin index by 11.818%, indicating its tyrosinase inhibition capacity. Also, PMC48 improved skin moisture content level by 20.943%. Additionally, 16S rRNA\u2010based amplicon sequencing analysis showed a distinct increase in Lactobacillaceae in the skin by up to 11.2% at the family level without affecting other skin microbiota. Furthermore, it showed no toxicity in in vitro or in vivo analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These results indicate that <jats:italic>P.
