As we enter the Maryland Laser, Skin, and Vein Institute (MDLSV), it appears to be the quintessential medical aesthetic practice. Patients relax in comfortable seating, soothed by soft lighting and the rippling sound of an elegant water sculpture. But just beyond the reception desk is a beehive of activity; a sprawling complex of hallways and treatment rooms, equipped with medical devices of every description. With four dermatologists and a staff of 40, this practice can treat 150 patients on a busy day. And with up to six Phase III clinical trials running at any given time, MDLSV is one of the world's leading dermatological study sites.
