Treat acne and reduce fine lines and wrinkles PDT represents the cutting edge of research in light based medicine, and works in two stages:
a photosensitizer is applied to the skin, and the body converts this into a chemical (often the naturally occurring chemical Protoporphyrin IX or PpIX).
The PpIX created responds to light within a certain waveband, provided by the Ellipse PR 530 or PL 400 applicators.
Two of the Ellipse SWT applicators are approved as the Light source for PDT treatments of the skin. The PR 530 applicator is already known for its use in vascular and photo rejuvenation treatments. This applicator matches three of the PpIX absorption peaks, allowing a photochemical pathway to be added to existing acne and photorejuvenation treatments. Because of the wavelengths and pulse times used, the PR 530 applicator is suitable for patients of Fitzpatrick Skin Types 1 to 3, with zero or light suntan. The PL 400 applicator - the latest addition to the Ellipse PLUS series – matches all 5 PpIX absorption peaks. By offering a series of longer, low energy passes, it offers a comfortable PDT treatment suitable for slightly more tanned patients, or those of Skin Types 1 to 4.
The facts about PDT
There are numerous peer-reviewed clinical articles that show the safety and effectiveness of PDT treatments. A large number of these involve using a specific photosensitizer in a treatment such as rejuvenation, acne and actinic keratosis.
