Effects of topical medications on the human skin microbiome
Alterations in the Human Microbiome With Commonly Used Topical Medications
This study tests how two common skin treatments, ketoconazole cream and desonide ointment, affect the balance of bacteria on the skin in healthy adults.

What this trial studies
This study investigates how commonly used topical medications, specifically ketoconazole cream and desonide ointment, alter the human skin microbiome over a short-term period. By utilizing modern molecular techniques, the research aims to characterize the diversity of skin microbiota and understand its implications for skin health. The study focuses on healthy adults, examining the microbiome changes in response to these topical treatments. The findings could provide insights into the balance between skin health and disease.
Who should consider this trial
Good fit: Ideal candidates for this study are healthy adults aged 18 and older without chronic skin diseases.
Not a fit: Patients with known chronic inflammatory skin conditions or those who have recently used antibiotics may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance our understanding of how topical medications affect skin microbiome health, potentially leading to improved treatment strategies.
How similar studies have performed: While the investigation of the skin microbiome is a growing field, this specific approach to studying the effects of topical medications is relatively novel.
Eligibility criteria

The inclusion criteria: • Adults at least 18 years of age. The exclusion criteria: * Individuals with known chronically active skin diseases, including atopic dermatitis, psoriasis, seborrheic dermatitis, other autoimmune and inflammatory skin conditions. * Patients with a history of skin cancer, multiple nevi, or other isolated lesions will not be excluded. * Individuals who have used topical, intravenous, intramuscular, or oral antibiotics within the last 6 months * Individuals with known allergies to any of the study medications. * Individuals younger than 18 years of age. * Adults unable to consent * Non-English speaking individuals. Given the complexity in the instructions that subjects will need to follow for proper sample collection, we will not seek to recruit non-English speaking individuals for this pilot study. * Prisoners
