Photodynamic therapy (PDT) is a non-invasive therapy that utilizes light treatments in combination with the application of a photosensitizing agent, typically 5-aminolevulinic acid.

First, the photosensitizing agent is applied to the skin, causing the skin to become more receptive to an activating light source.  After the agent is romoved, the light treatment is administered.  PDT was ariginally approved by the US Food and Drug Administration for the treatment of skin pre-cancers, but it has also been shown to be a safe and effective treatment for acne and several other skin conditions.
