Photodynamic therapy (PDT) is a medical procedure that combines a light-sensitive drug called a photosensitizing agent with a specific wavelength of light to destroy abnormal cells. This targeted treatment has become a cornerstone for managing precancerous skin lesions like actinic keratosis, certain nonmelanoma skin cancer types, and tumors affecting internal organs such as the esophagus and lungs.

PDT treatment combines a topical photosensitizer—typically aminolevulinic acid (ALA) or Ameluz—with controlled blue light or red light exposure to selectively destroy abnormal or overactive skin cells. This article walks you through real-world timelines, day-by-day recovery expectations, and how to prepare and care for your skin throughout the process.
