Introduction: Actinic keratoses are the most common premalignant skin lesions, with a chronic and recurrent nature. Daylight photodynamic therapy has been used in the treatment of actinic keratoses of the face and scalp.
Objective: To demonstrate the possibility of implementing daylight photodynamic therapy at a public service, for the treatment of facial actinic keratosis, using one tube of methyl aminolevulinate cream for up to four patients.
Methods: Ten patients were selected to undergo daylight photodynamic therapy at the Centro de Dermatologia Dona Libânia, located in the city of Fortaleza (CE), Brazil. Curettage was performed on the actinic keratosis and a methyl aminolevulinate cream based chemical filter was applied across the face.
Results: One tube of methyl aminolevulinate cream was enough for treating up to four patients with multiple facial actinic keratoses, whereas studies suggest the use of at least one gram to treat one face completely.
Conclusion: It was possible to conclude when administering daylight photodynamic therapy, an amount of less than one gram of methyl aminolevulinate cream in the treatment of facial actinic keratoses is a dosage sufficient to obtain an effective clinical response.
