Photodynamic Therapy (PDT)
Photodynamic therapy (PDT), sometimes called photochemotherapy, is a form of phototherapy using nontoxic light-sensitive compounds that are exposed selectively to light, whereupon they become toxic to targeted malignant and other diseased cells (phototoxicity). PDT has proven ability to kill microbial cells, including bacteria, fungi and viruses. PDT is popularly used in treating acne. It is recognized as a treatment strategy which is both minimally invasive and minimally toxic. In understanding the mechanism of PDT it is important to distinguish it from other light-based and laser therapies such as laser wound healing and rejuvenation, or intense pulsed light hair removal, which do not require a photosensitizer.
The procedure takes a few hours while you are exposed to a special light with the photo sensitive cream on. It requires some down time with peeling and redness afterwards. Not recommended just before a major social event. It is very effective to treat sun damage that keeps on returning with other treatment. It will rejuvenate skin and minimise signs of sun damage and aging.
