Targeted phototherapy is the localized delivery of ultraviolet (UV) light to affected areas of skin using laser or nonlaser devices [1]. This treatment modality may be useful in some patients with psoriasis, vitiligo, and other inflammatory or lymphoproliferative skin conditions (table 1) involving a limited area of the body (<10 percent of the body surface area) or difficult-to-treat anatomical areas [2].

This topic will discuss the mechanism of action, clinical indications, treatment protocols, and side effects of targeted phototherapy. Psoralen plus ultraviolet A (PUVA), UVB, and UVA1 phototherapy are discussed separately.

(See "Psoralen plus ultraviolet A (PUVA) photochemotherapy".)

(See "UVB therapy (broadband and narrowband)".)

(See "UVA1 phototherapy".)
