The method of treating psoriasis with ultraviolet UVB radiation

Psoriasis, also known as psoriasis, is a common erythematous and scaly skin disease. Its characteristic is the appearance of erythema on the skin, with silver white scales that peel off layer by layer after scraping, revealing a semi transparent film. The scraped film shows scattered bleeding.

UVB therapy: Narrow wave UVB is used for the treatment of moderate to severe psoriasis and locally refractory skin lesions, and can be used alone or in combination. It is generally treated 2-3 times a week, with a minimum dose of erythema. Ultraviolet light therapy for psoriasis generally refers to the treatment of psoriasis through ultraviolet light therapy, which can be divided into systemic irradiation therapy, local irradiation therapy, photochemical therapy, and combination therapy. How to undergo UVB treatment? The patient stands in a treatment device equipped with special UVB lamps, or is surrounded by one or more rows of lamps.

Patients usually receive treatment three times a week. Clearing psoriasis lesions requires an average of thirty treatments. The patient removed their clothes and exposed all areas of skin lesions to ultraviolet radiation. The first light exposure is usually very short, lasting as little as a few seconds. The irradiation time depends on the patient's skin type and the intensity of light emitted by the lamp used. People with lighter skin tone are more sensitive to UVB, and their initial exposure time is lower than that of people with darker skin.

Generally, the treatment time should gradually increase until the skin lesions begin to clear, unless there is eventually skin itching or pain. Because UVB phototherapy cannot provide precise timing, the response of each patient cannot be fully predicted. The treatment plan should be adjusted appropriately based on each patient's response.

If used correctly, UVB is often very effective, and most patients can clear skin lesions and achieve significant improvement. In a study, over 90% of patients achieved complete clearance of their skin lesions. However, the key to achieving maximum therapeutic effect is patient compliance: only by attending all appointments on time (usually at least three times a week) and following treatment guidelines can the best therapeutic effect be achieved.
