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 ...
There are four UVB types of lamps: Fluorescnt Broad-Band UVB that emit 280-330 nanometer, Fluorescent Narrow-Band that emit 312 nanometer, Excimer that emit 308 nanometer and LED that emit 290-300 nanometer. PUVA means UVA + psoralen. It consists of irradiation of the skin with the UVA ultraviolet light, from a fluorescent bulb or LED lamps.
Light therapy in the form of light boxes are a frequent non-drug treatment for SAD. Several preliminary studies have shown that light therapy is a positive treatment for depressive symptoms for older persons [ 8 ] [ 9 ] [ 10 ] although more studies need to be done in this area.
