Who is the study for?
This trial is for rosacea patients aged 18-60. Participants must be willing to have a combination of metronidazole and one of four moisturizers applied to their face, followed by non-invasive skin sampling at specific times during a single office visit.
What is being tested?
The study tests if applying moisturizer before the topical rosacea medication metronidazole affects how well it penetrates the top layer of skin. It involves randomly pairing metronidazole with one of four different moisturizers and measuring drug levels in the skin after application.
What are the potential side effects?
Since both metronidazole and the moisturizers are commonly used and FDA-approved, risks are minimal. The main side effect may be small, temporary bruises from where the tape strips collect skin samples.
