Ultraviolet light for Psoriasis Problem
UV therapy is one of the first treatments that a dermatologist may prescribe, and can be used on its own or in conjunction with another treatment. Phototherapy or light therapy, involves exposing the skin to ultraviolet light on a regular basis and under medical supervision. Treatments are done in a doctor's office or psoriasis clinic or at home with phototherapy unit. Through Ultra Violet special molecules present in skin cells are able to absorb the energy from UV light, and use it to power chemical reactions that affect the function of the cells. In psoriasis, this makes slowing down of the multiplication of skin cells, making them behave more like normal skin.
Now a day Ultra Violet B (UVB) is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule and UVB therapy is known to kill off T cells, which are partly to blame for the inflammation caused by the disease. There are two types of UVB treatment, broad band and narrow band. The major difference between them is that narrow band UVB light bulbs release a smaller range of ultraviolet light. Narrow-band UVB clears psoriasis faster and produces longer remissions than broad-band UVB. It also may be effective with fewer treatments per week than broad-band UVB. Although light therapy is safe and effective, the researchers say few people in Great Britain ever receive it because of limited availability of UVB light boxes, and time constraints of UV treatment at hospitals or clinics. Typically, a course of treatment requires three visits per week for eight to 10 weeks.
The skin may redden and itch from exposure to the UVB light. To avoid further irritation, the amount of UVB administered may need to be reduced and these reactions tend to resolve with continued treatment. With the UVB lamps not only you can defeat psoriasis but it is effective for vitiligo, neurodermatitis, eczema, lichen and other similar diseases within a few weeks. Instead of taking pills and stuffing your organism with chemicals, you have a chance to utilize the result of medical scientific progress the UVB phototherapy. Doctors often recommend UVB therapy if standard ointment treatments fail and if patients would rather avoid a systemic immunosuppressive drug regimen that has been developed more recently.
How to receive Ultra Violet Treatment
Patients usually receive treatments three times a week for several months at a dermatologist’s office or clinic. Before beginning treatment, patients are generally evaluated to determine the maximum amount of light they can tolerate without developing erythema, or reddening of the. Treatment begins at a lower exposure and the exposure is gradually raised.
Side Effects of UVB
The possibility that UVB treatment increases the risk of skin cancer cannot be dismissed, so patients receiving UVB should have annual skin cancer checks. And the most common side effect of UVB therapy is erythema, a sometimes painful reddening of the skin similar to sunburn.
