title: Evaluation of cutaneous tolerance to Kouriles Acne during sun exposure.
abstract: OBJECTIVE
  One of the main problems with the use of topical anti-acne agents during the summer season is the risk of inducing photosensitization and contact photoallergy. The aim of this study was to evaluate cutaneous tolerance to Kouriles Acne during sun exposure.
  
  
  METHODS
  The study population was 29 subjects with mild-to-moderate acne. The study product was applied to areas of the back which were then irradiated with a solar simulator.
  
  
  RESULTS
  The solar simulator produces imitation sunlight with a continuous emission spectrum approximating fairly closely that of terrestrial sunlight.
  
  
  CONCLUSIONS
  No changes in the study variables were observed in the skin areas treated with Kouriles Acne, demonstrating the complete absence of photosensitization reactions after use of the study product.
