Not Applicable
Completed
Conditions
Microbial Colonization
Registration Number
NCT06166979
Lead Sponsor
BLIS Technologies Limited
Brief Summary

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 scalp from a serum format in healthy adults.

Detailed Description

This is a randomized double-blind baseline 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 colonization by the probiotic bacterium (BLIS Q24) on the skin on the scalp and to evaluate the changes in skin quality parameters following topical application of probiotic in a serum format.

NameTimeMethod
Change in microbial composition following application of 1e8 cfu per dose Micrococcus luteus Q24 in serum from Day 0 (baseline) to 29 days29 days post intervention

Study will determine the change in microbial composition following the application of 1e8 cfu per dose serum containing Micrococcus luteus Q24 serum to the scalp. The statistical analysis will be carried out to compare the participants skin swab data from baseline to 29 days across one site with a level of significance of p\<0.05. Overall colonization based on percentage of population colonized for different interventions will also be analyzed using appropriate statistical analysis software. Analysis will be performed using bacterial genome sequence analysis of the skin swab samples collected.
