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 elbow and back of forearm in a topical balm format in healthy adults.
Detailed description
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.
Interventions
OTHERMicrococcus luteus Blis Q24 balm
Balm formulation containing probiotic bacteria Micrococcus luteus Q24 for topical applications.
OTHERPlacebo balm
Placebo balm formulation for topical applications.

A Staff member, not part of the study group will be assigned to distribute blinded samples. The investigator will not be are of the dose groups.
Intervention model description
Participants will be randomly assigned to one of two groups applying balm containing Micrococcus luteus Q24 or placebo balm. Group A: Probiotic Micrococcus luteus Q24 balm (dose:1e7 colony forming units per application of balm). Group B: Placebo balm (dose:0 colony forming units per application of balm).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in microbial composition on skin following application of Micrococcus luteus Q24 in balm from Day 0 (baseline) to 11 days | 11 days post intervention | 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. |
| Change in skin quality parameters following topical application of placebo balm from Day 0 (baseline) to 11 days | 11 days post last intervention | 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. |

| Change in microbial composition on skin post 10 days application of Micrococcus luteus Q24 in balm from Day 11 (baseline) to 18 days. | 7 days post last intervention | 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).
