Psoriasis is a inflammatory skin disorder which causes red skin patches with white or silvery scales that occur on arms, elbows, legs, face, and other body parts. Psoriasis is caused by increased cell turn-over time. Cell turn-over is the process where skin cells that are located deep inside the skin, rise up and grow on the surface of the skin then slough off. Dead skin cells are constantly shedding off and being replaced with younger cells. In normal conditions, it requires one month for cell turn-over, where as in psoriasis it happens in a few days leading to accumulation on skin surface causing psoriasis lesions. The lesions are usually itchy and cause inflammation. This is a chronic condition however it is not a communicable disease. Psoriasis is caused by false activation of immune system that stimulates the fast turnover of cells. Other factors that may increase the risk include skin infections, dry skin, smoking, and some medicines. It occurs both in men and women.
Excimer Laser is a novel te308chnique which involves treatment with high dose of ultraviolet B (UVB) radiations of nm wave length. This light directly falls on the target areas which are the light color spots for vitiligo and red skin patches for psoriasis. The skin cells that grow on the upper surface of the skin in psoriasis are destroyed due to the laser treatment. The system is designed to clear unsightly psoriatic skin plaques quickly and effectively. This can be used successfully on hard-to-treat areas of the body such as elbows and knees. In psoriasis, the scaly skin is resistant to the UV, so high dose of UV is given. Excimer laser offers effective treatment for localized psoriasis.
Excimer Laser can also be used to treat vitiligo. Treated areas regain the normal color of the skin. This procedure takes only several minutes. No additional medicine is needed with this technique. No scars remain on your body after this treatment. It allows your doctor to deliver the high-exposure doses necessary for rapid clearing without risk of damage to healthy skin.
Laser Treatment offers great results however the results will vary among individuals. Individuals with mild to moderate cases of psoriasis can often obtain relief in just four to ten brief treatment sessions. You may see some results immediately. Each case is unique, but psoriasis sufferers who have experienced treatment have found that relief can last for extended periods of time. Remissions are expected to last at least as long as with conventional phototherapy, but you will probably need fewer treatments per year to remain free of symptoms.
Although the excimer laser technique is advantageous and effective, it carries disadvantages that include exposure of skin adjacent to the treated lesions. High-dose treatment may affect the normal skin causing erythema (redness), blisters, or rashes, If you are tired of using creams with little to no result, or have lesions that simply won't respond to treatment, consider the excimer Laser system.
