Understanding Photodynamic Therapy (PDT)
Photodynamic Therapy (PDT) is a minimally invasive service that uses light-activated medication to treat damaged or abnormal cells. It's commonly used in dermatology and oncology to treat a range of skin conditions and early cancers.
What is Photodynamic Therapy (PDT)?
Photodynamic Therapy involves applying a light-sensitive drug to the target area and then exposing it to a specific wavelength of light. This activates the drug, destroying abnormal or diseased cells while sparing surrounding healthy tissue. PDT is used to treat:
Actinic keratosis (sun-damaged skin)
Acne
Certain types of skin cancer
Precancerous lesions
Psoriasis and other skin conditions
This service is valued for its precision and minimal recovery time.
