Psoriasis occurs when the immune system accelerates skin cell growth, leading to thickened plaques, scaling, and inflammation. Phototherapy remains one of the most proven, science-backed solutions to disrupt this rapid turnover while restoring skin balance.
Narrowband UVB therapy is the most widely recommended for moderate psoriasis, exposing affected skin to precise wavelengths of ultraviolet light three times weekly. This slows abnormal cell proliferation, calms inflammation, and reduces itch without damaging healthy tissue.
Broadband UVB treatment is often considered when psoriasis involves widespread skin areas. Though less targeted than narrowband, it is effective when applied under expert supervision.
PUVA therapy (Psoralen + UVA) combines a photosensitizing oral or topical medication with UVA exposure, enhancing skin responsiveness and improving resistant or deep plaques. It is often reserved for severe or chronic psoriasis where other methods fall short.
At Legacy Dermatology, phototherapy is not just about controlled light. Each session is customized to body area, skin type, and disease severity, with safety monitoring to prevent side effects. When combined with vitamin D compounds, topical retinoids, or biologics, results are longer-lasting and more transformative.
