Skin Conditions
Two forms of phototherapy exist, non-targeted phototherapy (from sunlight, a tanning booth or a light box), and targeted-phototherapy, in which light is administered to a specific, localized area of the skin. Current targeted phototherapy is administered via excimer laser, elemental gas lamp, or via LED light. Current FDA cleared devices on the market include XTRAC excimer laser, BClear, Theralight, and Psoria-Light LED phototherapy. Targeted phototherapy 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. With targeted phototherapy only being administered to the affected area of skin, more intense dosages of light can be administered, allowing skin conditions to be repaired in less time. As of early 2012, the only FDA-cleared device to offer both UVA and NB-UVB treatment within one device is the Psoria-Light.

Famous quotes containing the words skin and/or conditions:
“Surely the day will come when color means nothing more than skin tone, when religion is seen uniquely as a way to speak one’s soul; when birth places have the weight of a throw of the dice and all men are born free, when understanding breeds love and brotherhood.”
—Josephine Baker (1906–1975)
“Each victim of suicide gives his act a personal stamp which expresses his temperament, the special conditions in which he is involved, and which, consequently, cannot be explained by the social and general causes of the phenomenon.”
—Emile Durkheim (1858–1917)
