ultraviolet (UV) light therapy

Ultraviolet (UV) light therapy uses controlled exposure to specific wavelengths of UV light to treat various skin conditions, such as psoriasis, eczema, and vitiligo. The UV light helps slow down skin cell growth, reduce inflammation, and suppress immune responses locally. It is administered in a medical setting, with precise dosage to minimize risks. The therapy can improve symptoms and skin appearance, and is often used when other treatments haven't been effective. While effective, it requires careful monitoring by healthcare professionals to avoid side effects like skin aging or increased skin cancer risk.
