Fototherapy, also known as light therapy, is an effective treatment option for various skin diseases. It involves exposing the skin to specific wavelengths of light under controlled conditions to treat conditions such as psoriasis, eczema, vitiligo, and acne. The therapy uses ultraviolet (UV) light, which is administered through special lamps or light boxes.

One of the most common forms of fototherapy is narrowband UVB therapy. It works by targeting the skin’s immune system, reducing inflammation and slowing down the excessive growth of skin cells, which is particularly helpful for treating psoriasis. Similarly, fototherapy can also help in treating eczema by reducing itching and inflammation.

Another form of fototherapy is PUVA therapy, which combines a photosensitizing drug with UVA light. This method is typically used for more severe skin diseases, including psoriasis and vitiligo. PUVA therapy helps by altering the DNA in skin cells, making them less likely to reproduce abnormally.

Fototherapy is a non-invasive treatment that is often recommended when topical treatments fail or for patients who prefer not to use oral medications. The treatment can be done in a dermatology clinic, though some home devices are also available. Sessions typically last from a few minutes to 30 minutes, depending on the condition being treated.

While fototherapy can be highly effective, it’s important to follow medical guidelines to avoid potential side effects such as skin aging, burns, or an increased risk of skin cancer. However, under the guidance of a professional, fototherapy remains one of the safest and most efficient treatments for skin disorders.
