Efficacy of Methyl Aminolevulinate + Daylight in Patients With Facial Photodamage

A Double-blind Randomized-controlled Trial to Assess the Efficacy of Methyl Aminolevulinate + Daylight vs Placebo + Daylight in Patients With Facial Photodamage

Treatment of actinic damage has included multiple procedures but to date there is limited scientific evidence to support the preferential use of one of these therapies according to their efficacy, safety and pain tolerance by patients. This study aims to assess the efficacy of methyl aminolevulinate + daylight vs placebo + daylight to treat facial photodamage
