PDT is a procedure that uses a photosensitizing drug to apply light therapy selectively to target pre-skin cancer cells, acne and sun damaged skin.

What it can help/cure

PDT can help clear the skin of actinic keratoses which are premalignant growths in sun-exposed areas, mainly the face, chest, arms and hands. It is also effective for moderate to severe acne. A series of treatments can put acne into remission for months, as well as reversing some scarring without taking oral medications. When used with lasers for sun-damaged skin, the results achieved are better and faster than when using the light alone. There are many less common conditions that PDT can be used for, including hidradenitis suppurativa, Bowen%u2019s disease, superficial basal cell carcinoma and others.
