简要总结
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.
详细描述
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.

结局指标
主要结局
Change in microbial composition on skin following application of placebo balm from Day 0 (baseline) to 11 days
时间窗: 11 days post intervention
Study will determine the change in microbial composition following the application of a placebo balm at two body sites (elbow and back of hand). The statistical analysis will be carried out to compare the participants skin swab data from baseline to 11 days across two different sites 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.
Change in microbial composition on skin post 10 day application application of placebo balm from Day 11 (baseline) to 18 days
时间窗: 7 days post last intervention
Study will determine the change in microbial composition following the application of a placebo balm at two body sites (elbow and back of hand). The statistical analysis will be carried out to compare the participants skin swab data from Day 11 to 18 days across two different sites 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.
Change in skin quality parameters following topical application Micrococcus luteus Q24 from Day 0 (baseline) to 11 days
时间窗: 11 days post last intervention
Study will determine the change in skin quality parameters using a skin quality analyzer following topical application of Micrococcus luteus Q24 balm at two body sites (elbow and back of hand). The statistical analysis will be carried out to compare the participants skin quality data from baseline to 11 days across two different sites with a level of significance of p\<0.05.
