fototerapiassa

Fototerapiassa, also known as phototherapy, is a medical treatment that uses specific wavelengths of light to treat various skin conditions. It is a non-invasive procedure where a patient's skin is exposed to ultraviolet (UV) light under controlled conditions. The most commonly used types of light are ultraviolet A (UVA) and ultraviolet B (UVB). Narrowband UVB, which uses a specific range of UVB light, has become increasingly popular due to its effectiveness and potentially fewer side effects compared to broadband UVB.

The therapeutic effects of phototherapy are complex and involve modulating the immune system within the skin. Light exposure can reduce inflammation, decrease the overproduction of skin cells, and inhibit the activity of certain immune cells that contribute to skin diseases. This makes it a valuable treatment option for conditions such as psoriasis, eczema (atopic dermatitis), vitiligo, and cutaneous T-cell lymphoma.

Treatment is typically administered in a doctor's office or specialized clinic using phototherapy booths or units. The duration and frequency of sessions vary depending on the condition being treated, the type of phototherapy used, and individual patient response. Patients are usually advised to protect their eyes during treatment and to avoid sun exposure afterward. While generally safe, potential side effects can include redness, itching, and dryness of the skin, similar to a sunburn. Long-term or excessive exposure can increase the risk of premature skin aging and skin cancer, which is why treatment is closely monitored by healthcare professionals.
