After topical application of Metvix (methyl aminolevulinate), porphyrins accumulate intracellularly in the treated skin lesions. The intracellular porphyrins (including PplX) are photoactive, fluorescing compounds and, on light activation in the presence of oxygen, singlet oxygen is formed, which causes damage to cellular compartments, in particular the mitochondria. Light activation of accumulated porphyrins leads to a photochemical reaction and thereby phototoxicity to the light-exposed target cells

An NSAID gel for actinic keratosis containing 3% diclofenac.
