Purpose of study: Evaluation of the affect of dose rate on UVR induced skin erythema.
Study design: A single-center, prospective, randomized, crossover, open study.
Number of patients: 20-40
Patient population: Healthy volunteers
Control: Different sites on patients body
Procedure duration: Total 3-5 hours (4 visits)
Duration of follow up: 4 days
Duration of study: Up to 6 months
Primary objectives: To examine the difference in erythemal response as a function of dose rate, and to assess the total amount of energy that is theoretically transmitted through a sunscreen within the range of SPF 2-10.
