Red light therapy consists of exposure to daylight or to specific wavelengths of light using polychromatic, polarized light, lasers, light emitting diodes, fluorescent lamps, dichroic lamps or very bright full spectrum light, usually controlled with various devices. The light is administered for a prescribed amount of time and, in some cases, at a specific time of day. Light therapy is a common form of treatment for a variety of conditions from auto immune disorders like psoriasis, eczema, vitiligo to wound healing, depression, seasonal affective disorder and circadian rhythm sleep disorders. Two forms of phototherapy exist, non-targeted phototherapy (from sunlight or a light box like those found at tanning salons), and targeted-phototherapy, in which light is administered to a specific, localized area of the skin. Current targeted phototherapy is administered through excimer lasers, elemental gas lamps, or LED lights.
The FDA has cleared devices on the market including XTRAC excimer laser, BClear, Theralight, and Psoria-Light LED phototherapy. Targeted phototherapy is administered in a doctor’s office and is only administered to the affected skin, not the entire body, thus sparing healthy skin from UV rays which may lead to other health issues including skin cancer. While different wavelengths work for different conditions, treatment is most often done with narrow band UVB (NB-UVB) as this is the safest wavelength. Non-targeted phototherapy can be delivered at doctor’s office or at home via prescription using a booth, multidirectional unit, or wand; the unaffected skin is simply covered. Several devices are FDA-approved for home including the Panosol 3D, Richmond Light and Solarc Handheld.
Red light easily penetrates the skin and boosts circulation, releasing more blood and nutrients to the area. It also stimulates vital collagen and elastin production; collagen helps plump the skin, while elastin firms the skin. The red light is energizing as it repairs damaged cells and restores skin back to its youthful look.
