20% 5-ALA ampoules will be crushed and prepared for application after shaking for 3 minutes. Topical ALA will be applied liberally on skin with extra pressure on lesions. Incubation of ALA will take place for 0-3 hours. Exposure to Blue U light source (417 nm) (DUSA), will be performed for Actinic Keratosis for 15 minutes. Application of combination light sources will be performed when lesions are traced with one pass of Pulsed dye laser (595 nm) (Candela) followed by exposure to Blue U light source for 5-8 minutes pending response.
5-FU, Imiquimod or treatment with cryotherapy to lesions on the skin.
