Outcome Measures

Primary Outcomes (8)

  • Change in microbial composition on skin following application of Micrococcus luteus Q24 in balm from Day 0 (baseline) to 11 days

    Study will determine the change in microbial composition following the application of a balm containing 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 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.

    11 days post intervention

  • Change in microbial composition on skin following application of placebo balm from Day 0 (baseline) to 11 days

    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.

    11 days post intervention

  • Change in microbial composition on skin post 10 days application of Micrococcus luteus Q24 in balm from Day 11 (baseline) to 18 days.

    Study will determine the change in microbial composition post 10 days application of Micrococcus luteus Q24 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 microbial composition on skin post 10 day application application of placebo balm from Day 11 (baseline) to 18 days

    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.

    7 days post last intervention

  • Change in skin quality parameters following topical application Micrococcus luteus Q24 from Day 0 (baseline) to 11 days

    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.

    11 days post last intervention

  • Change in skin quality parameters following topical application of placebo balm from Day 0 (baseline) to 11 days

    Study will determine the change in skin quality parameters using a skin quality analyzer following topical application of placebo 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.
