PDT - Photodynamic therapy, or another way of saying using specific wavelengths of light to treat certain skin conditions. In most cases PDT also involves the use of Levulan (aminolevulanic acid) to greatly enhance the effectiveness of a treatment. This is solely done under the supervision of a doctor.
LLLT - Low level light therapy, the acronym used by the scientific community to describe all manner of light therapy options. These include applications for pain management, wound healing, anti-aging, and skin treatments.
Photofacial - A high intensity light therapy treatment, usually performed at a dermatologist office or medical spa, that attempts to remove discolored spots, wrinkles, or redness from the face, chest, or body of a customer. Can also be spelled fotofacial.
Nm - Nanometers, or how the wavelength of the light spectrum is measured. The human eye can detect light in the 390nm to 750nm range. Any light below 400nm is considered UV, or ultraviolet, and light above 800nm is considered IR, or infrared.
Blue Light Therapy - A specialized form of light therapy that singles out light in the 405-420nm wavelength range. This small spectrum of light has been proven to kill acne causing bacteria.
