Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.
Methyl aminolevulinate (MAL) is a drug used as a photosensitizer in photodynamic therapy like LEDT. The red-light MAL-LED therapy performed significant therapeutic effects on the recovery of papulopustular lesions in an in-vivo clinical trial conducted with rosacea patients. A more recent study proves the in-vitro effect of LEDT at wavelengths ...
The penetration depth of white light and LED light into the skin increases with increasing wavelength from the UV to the visible light range, and then decreases again in the IR range depending on the selected optical properties. This depth further increases if the thickness of the stratum corneum decreases. [23]
Red light therapy is relatively new and its potential applications and benefits are an ongoing area of research, the experts note. While it has shown to be promising for some conditions, many of ...
What is light therapy? “LED light therapy, or light-emitting diode therapy, is a non-invasive skincare treatment that uses specific wavelengths of light to stimulate various cellular processes ...
Bright light therapy is a treatment method that involves exposure to a high-intensity light source that mimics natural sunlight, says Frank A. Ghinassi, Ph.D., senior vice president of Behavioral ...
