What is psoriasis Light Therapy?

Light therapy Psoriasis includes the use of two ultraviolet, UVA and UVB, to reduce psoriasis, a condition in which skin cell production accelerates. Sunlight is used to treat psoriasis for more than a century. The only types of ultraviolet light that proved to be beneficial in the treatment of psoriasis are UVA and UVB.

Skin cells usually last between 21 and 28 days to replace, but this process accelerates up to two to six days with psoriasis suffering. Psoriasis is represented as a psoriatic plaque that increases, red skin areas caused by an increased number of blood vessels needed to adapt to an increase in cell production. These red areas are covered with silvery-white "scale", accumulation of skin cells waiting for shedding. Psoriasis may also occur in more sensitive areas such as weaknesses, genitals and undersharms; These areas usually do not have scales but are raised and red. Psoriasis can be painful, itchy and painful and in a heavy caseH can burst and bleed.

Phototherapy is the term treatment of psoriasis using ultraviolet light. In order to benefit psoriasis, UVA must be combined with PSOLAREN, a chemical agent that makes the skin more sensitive to UVA. This combined treatment called Puva was introduced in the 70s. Psolen can be used in the form of a tablet or as a bath, ointment or cream oil. After setting the time designated by a healthcare professional, the skin is then exposed to UKA radiation in radiation, which is similar to the appearance of the shower cabin, or using a small portable unit depending on the size of the area requiring treatment.

protective eye glasses must be worn when the treatment of PSOLAREN begins to prevent eye damage, which also more sensitive to UVA using Psolene. Glasses must be worn inside, because UVA is able to penetrate glass. It may take up to three months of treatment before improvementU psoriasis. Once treatment is completed, the skin may remain from psoriasis for up to six months.

Psoriasis Light therapy using UVB has been used since the 20th century. UVB is recommended for psoriasis, which did not respond to other treatment. It is a wavelength of sunlight responsible for causing the highest burning. The UVB wavelength, which is beneficial in psoriasis light therapy, is a very narrow band between 300 and 313 nanometers. UVB therapy is administered inside the radiation cabinet using ultraviolet light tubes. The sunglasses must be worn inside the cabinet to prevent eye damage.

Since the widespread exposure to ultraviolet light may have potentially serious side effects, the amount of ultraviolet light must be carefully and precisely calculated by a healthcare worker. Psoriasis light therapy usually lasts between six and 12 weeks, depending on the type of light therapy, with treatment up to three times a week and at least 48 hours between treatment to allow the skin to recover.Potential side effects of using psoriasis light therapy include burning, itching, dry leather, freckles, premature skin aging and skin cancer. The humidifier should be liberally applied after each treatment to minimize dryness and itching. The persistent itching or burning should be warned as soon as possible by healthcare workers.
