Who these studies look for
Most require an active, diagnosed skin condition of a certain severity and a pause on some current treatments before starting.
Matching a page like this one never means you qualify. Each research team decides eligibility at screening.
Questions
Do I need a diagnosis to join a skin study?
Usually yes, and the site will confirm it at screening. Some studies also recruit people without the condition as a comparison group.
