Photodynamic Therapy for Pre-Skin Cancer Treatment

Levulan is an FDA-approved topical solution applied directly to areas of sun damage or actinic keratoses. Once absorbed by abnormal cells, it is activated by blue light (BLU-U®), producing a targeted reaction that selectively destroys precancerous tissue while leaving healthy surrounding skin intact. Levulan PDT is a well-established, clinically proven treatment for actinic keratoses and is particularly effective for field treatment of widespread sun-damaged areas such as the face, scalp, chest, and hands.

Ameluz is a prescription-strength gel formulation of aminolevulinic acid that is activated by red light (RhodoLED®). Red light penetrates more deeply into the skin than blue light, allowing Ameluz PDT to reach and treat thicker or more stubborn actinic keratoses. Ameluz is FDA-approved for the treatment of actinic keratoses of mild-to-moderate severity and offers a highly effective option for patients with more advanced sun damage or lesions that require deeper penetration.
