Phototherapy utilizes the beneficial effects of ultraviolet UV wavelengths to affect immunoregulatory functions. Dual-action mechanisms of UV phototherapy have been identified: apoptosis and immune suppression. Other wavelengths are also utilized for phototherapy, namely nm excimer light and nm flat-typed NB-UVB. Excimer light nm therapy effectively targets the affected skin without unduly exposing other areas and increases the levels of regulatory T cells. Phototherapy improves impaired resting regulatory T cells and increases activated regulatory T cells in patients with psoriasis. Intensive studies of phototherapy effects have led to several improvements in the design, protocols, and light sources, such as UV light-emitting diodes, thereby providing several options for patients with refractory skin disease, such as psoriasis.

Phototherapy for Psoriasis: What You Need to Know

Jump to navigation. Phototherapy or light therapy is a prescription treatment that is typically prescribed by a dermatologist. Treatments are done in a doctor's office or psoriasis clinic or at home with a phototherapy unit. The key to success with light therapy is consistency.
