Porphyrin distribution after topical aminolevulinic acid in a novel porcine model of sebaceous skin

Aminolevulinic acid photodynamic therapy (ALA‐PDT) depends on drug metabolism into porphyrins. Clinically, ALA‐PDT has been used with a wide range of protocols for treating both epidermal and dermal targets, despite limited understanding of porphyrin biodistribution over time. We studied porphyrin accumulation after topical application of ALA in vivo, and also describe the porcine ear as a new animal model to study adnexal glands.
