Researchers are looking for healthy people who are nonsmokers, have Fitzpatrick skin types 1 or 2 (meaning that a person is fair- to light-skinned, burns easily, and tans rarely), and have not used antibiotics recently.
The study, titled Effect of Orally Delivered Phytochemicals, Alone and in Combination, on Aging and Inflammation-Related Effects in the Skin, has the following components:
Participants will be on a cruciferous-free diet (no broccoli, cauliflower, kale, cabbage) for a month and will be required to make nine to 10 visits to the Johns Hopkins Outpatient Center over four weeks. During these visits, controlled UV light will be applied to multiple small areas on the buttocks. This is similar to the effects of getting a very mild sunburn. The redness of these areas will be measured daily with a chroma meter, and photographs will be taken (de-identified to protect your confidentiality). Over the course of the study, 10 punch biopsies will be taken from the buttocks. Participants will take a 10-day course of dietary supplements and provide two overnight 24-hour urine collections and two blood draws.
Compensation: $300 upon completion of all components of the study
