UV light therapies have gained attention as a treatment for plaque psoriasis, a chronic skin condition affecting many individuals.
Q: What is plaque psoriasis?
A: Plaque psoriasis is a chronic autoimmune skin condition characterized by red, inflamed patches covered with silvery-white scales. It typically occurs on the elbows, knees, scalp, and lower back but can appear anywhere on the body.
Q: How does UV light therapy work?
A: UV light therapy works by exposing the skin to controlled amounts of ultraviolet light, which helps to slow down the rapid growth of skin cells that is characteristic of psoriasis. This treatment can reduce inflammation and alleviate symptoms.
Q: What types of UV light therapy are available?
- UVA Therapy: Involves exposure to long wavelengths of ultraviolet A light.
- UVB Therapy: Uses shorter wavelengths and is commonly employed to treat psoriasis.
- PUVA Therapy: Combines psoralen (a sensitizing medication) with UVA exposure to enhance treatment effectiveness.
Q: What is the effectiveness of UV light therapies?
A multitude of studies have demonstrated the effectiveness of UVB therapy in particular for plaque psoriasis. In clinical trials, over 50% of patients reported significant improvement after consistent treatment.
