Systems and methods for targeted uvb phototherapy for dermatologic disorders and other indications

Abstract

The present disclosure is directed to systems and methods for targeted UVB phototherapy for dermatologic disorders and other indications. In one embodiment, a phototherapeutic system can include a radiation source configured to emit light. At least 75% of the light emitted by the radiation source can have wavelength with a bandwidth between 298 nm and 307 nm. The phototherapeutic system can also include a controller operably connected to the radiation source and configured to determine a dosage for a phototherapy session. Dosage can correspond to a product of the intensity of the radiation source and an exposure time of the radiation source, and may have an upper bound less than 1 minimal erythema dose (MED). Delivery of the dose of phototherapy can stimulate production of calcitriol and vitamin D3 in the user's skin and can provide an immune response to treat a dermatological disorder.
