Volunteers with skin of color needed

Topical tretinoin is often prescribed for photoaging in lighter-skin types. Researchers in the Department of Dermatology would like to understand the effects of tretinoin on darker-skin types. African-American healthy adult participants can join this study, which involves up to five study visits, photography, topical tretinoin application, and skin biopsies. The study will take up to four weeks and offer $100 upon completion.
