Objective To identify environmental factors that correlate with skin photoaging, controlling for genetic susceptibility by using a questionnaire administered to twins.
Design The survey collected information about each participant’s Fitzpatrick type, history of skin cancer, smoking and drinking habits, and weight from a cohort of twins. Clinicians then assigned a clinical photodamage score to each participant.
Setting The annual Twins Days Festival in Twinsburg, Ohio.
