What is ultraviolet light?

Ultraviolet light as therapy for skin condition

UV light is reproduced artificially by using device producing UV radiation. Some of the devices producing artificial UV light are tanning booths, black lights, curring lights, some types of laser, mercury vapor lamps and fluorescent and incandescent lamps. Laser arch and lamps with various wavelengths are used for medical purposes. One good example of these UV lamps is Germicidal lamp which produces UVL or ultraviolet light. The device produces short-waved UVL and disturbs the DNA based pairing that is responsible in the formation of molecular lesions leading to the inactivation of bacteria and viruses. Another kind is UV-B lamps which produces UV light with wavelengths ranging from 290-320 nonometers which human sensitivity is at high rate. UV-B lamp is for treating skin conditions such as vitiligo, eczema, psoriasis, and Lichen Planus. UV-B is different from UV-A which is for tanning purposes.

Treating skin conditions with ultra violet light

Eczema is a skin condition caused by inflammation. The most common type is Atopic dermatitis. It is common in skin areas like cheeks, chin, chest, neck, inner elbows and behind knees. Eczema is common to be itchy which can be mild or moderate. When the condition becomes worse, it developed into inflamed skin. Symptoms include very bad itching, dark colored patches and skin can be rough and leathery, and some people have scaly patches. In worst cases, there is oozing and crusting on skin. While the symptoms can go away, the itching can go so bad and sufferers scratch it until it bleeds which makes the eczema worse.

In treating eczema, a special device is used which produces ultraviolet light or UV-B and the body or parts of the body is exposed to the light for a few   seconds or minutes. During the ultraviolet light therapy, treatment is carefully recorded and light is reduced after several sessions depending on the body reaction to the treatment.  When improvements are noticed, the treatment is temporarily stopped to see if the condition is in remission. If the treatment is successful, patient is advised for maintenance treatment.

It must be remembered that if the treatment produces good results, it is not as rapid but patients are required for repeated sessions. Improvement is generally slow and usually seen between 1 to 2 months. Treatments using ultraviolet light are boosting success rates. It is also a treatment that is less invasive and manufacturers like UVLrx are government approved which makes ultraviolet light devices safe.

If you’re suffering from eczema or other skin conditions, consult your Dermatologist and ask about UVL therapy.
