Light therapy, also referred to as phototherapy, is a type of therapy that involves exposure to light that is brighter than indoor light though not as bright as direct sunlight. This therapy is often used in the treatment of conditions such as depression, jet lag, and sleep disorders. Light therapy is also used to treat seasonal affective disorder (SAD), as it helps reset the circadian rhythms, which controls the sleep-wake cycle.
Light therapy employs light with wavelengths ranging from 390 nm – 1,100 nm that uses LED, fluorescent lamps, polychromatic polarized or full-spectrum to administer a certain amount of time during a specific time of the day.

Light therapy causes photo-oxidation and thus a primary treatment method for neonatal jaundice, eczema, and psoriasis. Narrow band ultraviolet (UVB) and broad band UVB phototherapy are issued for treatment of skin disorders. Increasing applications, favorable reimbursement policies, and insurance for such treatments is expected to boost demand for the light therapy. Treatment of acne by using LED light is gaining popularity, owing to various benefits such as cellular rejuvenation and improved blood circulation.
LED light therapy is more effective than conventional therapy, as it emits blue and red light, which are beneficial for treating acne and wrinkles. Markets in developed countries are witnessing increasing demand for light therapy products due to the geographic location and high prevalence of SAD. Adoption of light therapy devices such as light boxes and handled devices are projected to increase at very high rate over the forecast period, owing to increasing prevalence of skin-related diseases, which in turn, is caused by increasing adoption of unhealthy lifestyle and eating habits among the populace. Growth of the light therapy market is expected to be hampered due to shortage of funding for light therapy research and post treatment side effects.
