Summary
This study tests a medicated foam (AMZEEQ®) on a rare skin condition called CARP, which causes brown, scaly patches. About 35 people aged 9 and older will apply the foam to one side of their body and a plain moisturizer to the other for 5 weeks. The goal is to see if the foam is a safe and effective alternative to oral antibiotics.
