- •Ability to administer topical medication and be willing to adhere to the study interventions.
- •Agreement to adhere to Lifestyle Considerations throughout the duration of the study.
Exclusion Criteria
- •Pregnancy or lactation.
- •Any type of malignancy involving the Study Site Area (Lesion or Non-Lesion site) in the last 5 years.
- •Known allergy to hydrocortisone or topical antibiotic.
- •Topical or oral use of an antibiotic within the last 7 days prior to baseline clinical visit.
- •Bleach bathing in the 7 days prior to Baseline clinical visit.
- •Current use of Class I-III topical corticosteroids or systemic medications (e.g. Dupixent) potentially affecting eczema or the skin.
- •Surgeries or invasive medical procedures planned during course of study.
- •Suspected non-compliance or non-cooperation.

Outcomes
Primary Outcomes
Atopic Dermatitis Severity Index (ADSI) score
Time Frame: 14 days
Change in mean Atopic Dermatitis Severity Index (ADSI) score from baseline between the protocol and control arms by the 14-day application period. The ADSI comprises an assessment of erythema, pruritus, exudation, excoriation, and lichenification, each on a scale of 0 to 3 to give a maximum score of 15. The maximum score means a worsen condition.
Change in absolute abundance of S. aureus on target lesion site
Time Frame: 14 days
Difference in reduction in absolute abundance of S. aureus on target lesion site compared to initial absolute abundance at target lesion site (Baseline measurement) between the protocol and control arms by 14-day application period of application period.
Secondary Outcomes
- Change in Eczema Area and Severity Index (EASI) score(14 days)
- Change in relative abundance of S. aureus on non-lesion site(14 days)
- Change in absolute abundance of S. aureus and S. epidermidis on target lesion versus non-lesion site.(14 days)
- Change in Shannon Diversity Index between the target lesion site and non-lesion site(14 days)
