Which modality employs ultraviolet light for therapy, including skin treatment?

Ultraviolet therapy uses energy in the ultraviolet range to produce photochemical changes in the skin, which can help treat certain skin conditions and aid healing. This modality is distinguished by its use of UV light to affect skin tissue, including conditions like psoriasis, dermatitis, acne, and wound healing, often with careful dosing and safety precautions. The other options rely on different mechanisms: infrared therapy provides heat to increase blood flow and tissue extensibility; diathermy uses high-frequency electrical currents to generate deep heating; whirlpools use warm water and agitation for hydrotherapy. None of these involve ultraviolet light for skin-directed treatment, which is why ultraviolet therapy is the best choice for this question.
