"Is photodynamic therapy more effective than topical treatments in the treatment of seborrheic dermatitis?"
18 to 100 years old
This study seeks to determine the effectiveness of a new treatment method using a chemical called aminolevulinic acid (ALA), which is placed on the skin followed by blue light exposure, called, photodynamic therapy (PDT), in the treatment of seborrheic dermatitis. This study also seeks to determine how PDT alters the skin microbiome (bacteria normally found in the skin) in patients with seborrheic dermatitis before and after treatment.
This study requires
Wash face with only Dove soap Facial photography Swabs of facial sites Measurement of facial sebum production rates with SebuMeter® Application of ALA to treatment side and placebo to control side with one hour incubation Exposure to blue light per UC Davis Dept of Dermatology standard protocol
