Which skin pigmentation condition is treated with ultraviolet light therapy?

• A. Acne
• B. Vitiligo
• C. Psoriasis and eczema
• D. Melasma

Answer: (C)

Ultraviolet light therapy is primarily used to treat conditions that involve skin inflammation and hyperproliferation, such as psoriasis and eczema. In psoriasis, UV light helps to slow down the rapid growth of skin cells, reducing the scaling and inflammation associated with the condition. Similarly, for eczema, UV therapy can help reduce inflammatory responses and alleviate symptoms. While conditions like acne and vitiligo may have other treatment modalities involving light or lasers, the specific usage of ultraviolet light therapy is most effective and widely recognized for psoriasis and eczema. Melasma, on the other hand, generally responds better to topical treatments and chemical peels rather than UV light therapy, as UV exposure can sometimes exacerbate pigmentation issues in this condition.
