Photodynamic therapy (PDT) is a type of treatment for precancerous skin growths called actinic keratoses. This treatment combines the use of a topical medical with a source of light. The topical medication used in this treatment is a photosensitizer. The photosentizing agent used in PDT at Hancock Dermatology is aminolevulinic acid. The light source used at Hancock Dermatology is the BLU-U light. This light may also be used for the treatment of acne.
Aminolevulinic acid is a solution used to treat actinic keratoses and superficial basal cell carcinomas. It is used with Blue light. Once this photosensitizing medication is activated by light of a specific wavelength, they react with oxygen and kill cancerous and precancerous cells.
