Summary
Photodynamic therapy is an effective treatment for actinic keratoses. In the United States
topical aminolevulinic acid (ALA) is approved as a photosensitizing agent for this treatment,
and it has traditionally been activated with the use of an in-office artificial light source.
This clinical trial seeks to measure the safety and efficacy of using natural sunlight to
activate the ALA.
