Clinical Evaluation of Skin Microbiome an Over-The-Counter (OTC) Drug for Atopic Dermatitis

Clinical Evaluation of the Skin Microbiome and the Efficacy of an Over-The-Counter (OTC) Drug for Atopic Dermatitis

This is a research study. The over-the-counter (OTC) drug for atopic dermatitis being tested is not approved as a treatment for the participants' atopic dermatitis condition. In participating in this study, the investigators will analyze the participants' skin microbiome, measure skin hydration and barrier function, and assess clinical improvements to help us understand the potential impact of the investigational OTC drug on atopic dermatitis and skin microbiome balance.

Inclusion Criteria:

• Previously diagnosed Atopic Dermatitis with active, visible flare-ups at time of screening
• Present dry/itchy skin patches on forearm, back of the hand, or posterior lower leg suitable for treatment assessment
• Evidence of inflammatory disease (documented diagnosis and current active symptoms)
• Stable skincare routine for 4 weeks prior to screening
• Subject willing to avoid conflicting topical treatments during study period
• Subject being used to applying topical treatments for atopic dermatitis

• Recent use of systemic antibiotics, steroids, or immunomodulators (within 4 weeks)
• Active skin infections unrelated to atopic dermatitis
• Severe dermatologic conditions requiring immediate medical intervention
• Use of topical or systemic treatment during previous weeks liable to interfere with assessment
• Subject having undergone surgery under general anaesthesia within the previous month
