Photodynamic Therapy (PDT)
Photodynamic Therapy is a medical treatment that utilizes a photosensitizing liquid applied to the skin and a light source like the sun to activate the drug. It treats superficial skin cancers, sun spots (Actinic Keratoses), Rosacea, Acne, and other skin conditions. It is also known as “Blue Light Treatment”. The greatest advantage of PDT is that it selectively treats an entire area of skin damage because the photosensitizing medication is only absorbed by the damaged skin cells and leaves the normal skin cells intact. PDT therapy avoids the usual problems of routine freezing with liquid nitrogen which are lighter or darker skin spots & scarring in the areas treated.
How does it work? The photosensitizing medication is applied to the skin to be treated and the patient is exposed to the sun for 2-3 hours. The treated skin will be red for a few days and the damaged skin or spots will get darker and fall off. Usually 1-3 sessions are required, depending on the patient’s response.
Aside from being a “Pre Cancer” therapy, the treatment will result in an even skin tone & color, enhanced skin texture, and an overall improved cosmetic appearance.
