UV Phototherapy for psoriasis

Psoriasis is a chronic inflammatory skin disease. In addition to medication, physical therapy can also be chosen for the treatment of psoriasis. In this issue, we introduce the currently most widely used ultraviolet light therapy.

In ancient Europe, people often went to Italy to sunbathe when they had skin diseases. Nowadays, various types of light therapy equipment have emerged under the evolution of "phototherapy". With the continuous development of medical technology, ultraviolet light therapy in physical therapy has also been used for the treatment of psoriasis, which is the preferred treatment for psoriasis today.

Many people worry that exposure to ultraviolet light will darken the skin color and accelerate skin aging with long-term exposure. However, in fact, ultraviolet light exposure can inhibit the proliferation of lymphocytes, reduce the number of inflammatory cells, alleviate the inflammatory reaction in psoriasis lesions, and suppress immune reactions mediated by helper cells. In general, ultraviolet light therapy for the treatment of psoriasis has many advantages.

Ultraviolet light therapy is one of the important methods for the treatment of psoriasis and other skin diseases. Among them, narrowband ultraviolet B (NB-UVB) with a wavelength of 311nm has the best therapeutic effect on psoriasis and is widely used in the treatment of skin diseases. NB-UVB has the following advantages:

1. Fast and effective

Based on domestic and foreign experience, NB-UVB generally shows significant effects after about 20 irradiations.

2. Safe and harmless

With the gradual improvement of phototherapy equipment, its safety has also gradually improved. NB-UVB is currently the safest method for treating psoriasis.

3. Prevents recurrence

NB-UVB not only inhibits abnormal immune and proliferative reactions in the affected skin, but also clears the T cells that are abnormally present in the skin and are related to the onset and recurrence of the disease. Therefore, it has the effect of "treating the root cause" and can minimize and alleviate recurrence.

4. Reduces treatment costs

The consumption of phototherapy equipment during the treatment process is relatively small, and the cost is relatively low. Compared with other treatments, it is a relatively economical treatment method.

Through the above introduction, do you now understand the treatment of psoriasis with ultraviolet light? Phototherapy not only has good therapeutic effects on psoriasis, but also has good effects on the treatment of many other skin diseases.
