Photodynamic therapy is a recently approved development in the treatment of sun damaged pre-cancerous zones and spots called actinic keratoses. It is performed with a topical photosensitizing agent called Levulan (5-aminolevulinic acid) that is activated with the correct wavelength of light emitted from a BLU-U® light machine. (This is known as “ALA/PDT treatment.”)
PDT can have cosmetic benefits as well. The signs of sun damage, some fine lines, and blotchy pigmentation have also been shown to improve because of the positive effects of Levulan and PDT. ALA/PDT treatment can also minimize pores and reduce oil glands, effectively improving acne vulgaris and Rosacea. PDT has also been shown to improve the appearance of acne scarring.
