Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the skin quality improvement and colonization efficacy following the application of probiotic Micrococcus luteus Q24 (BLIS Q24) to the elbow and back of forearm in a topical balm format in healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized double-blind, placebo-controlled pilot study with no crossover for the assessment of any changes to the microbial make-up of the skin (The local skin microbiome), detection of colonisation by the probiotic bacterium (BLIS Q24) on the skin and to evaluate the changes in skin quality parameters following topical application of probiotic in a balm format.
