UVR has been shown to be a beneficial treatment for a variety of chronic skin problems, and its capacity to relieve these symptoms has been widely established. UV light, despite not being ionising, damages deoxyribonucleic acid integrity and produces a variety of unpleasant side effects, ranging from erythema (sunburn) to cancer. Due to the chronic nature of the illnesses treated with this medication, exposures are repeated and can be considerable, raising the lifetime risk of an adverse event or mutagenesis consequence.
What Is Ultraviolet Light Therapy and How Does It Work?
The use of ultraviolet light to remove infectious organisms or damaging cells that cause disease in the body, particularly superficial lesions and skin infections, is known as an ultraviolet light treatment.
The sun emits ultraviolet light naturally, but it can also be channelled for treatment using specifically constructed instruments.
The wavelengths of light are varied. Longer wavelength UVA light and shorter wavelength UVB light are the most often employed wavelengths in therapeutic ultraviolet light treatments.
How Do I Get Ready?
If you and your doctor are thinking about using UV light therapy to treat your problem, your doctor may recommend a pre-treatment eye check to see if you have cataracts.
What Should I Wear?
Wear comfortable clothes that are easy to take off and put back on after your therapy session.
During your treatment, you may be requested to change into a hospital gown, or you may be permitted to stay in your regular clothes while only exposing the part of your skin that has to be treated.
Recovery
You may be sensitive to sun-induced sunburn if you receive UV light treatment on a regular basis for several months.
You may be told to stay out of the sun for a few days following each treatment or to wear sunscreen when going outside.
What Is Ultraviolet Light Therapy Used For?
This medication is used to treat skin infections and disorders. It has the potential to relieve your symptoms and perhaps cure certain skin infections. However, the results of ultraviolet light therapy for the chronic inflammatory disease may be transitory, and the condition may reappear months or years after treatment is stopped.
The following conditions are treated using UV light therapy:
What is the UV dose for therapeutic?
UV therapy is sometimes used to treat psoriasis, acne, and eczema, among other skin conditions. UV radiation dosage is governed by an individual's skin sensitivity, which is based on their Fitzpatrick skin types I through VI (very fair to very dark). Because of differences in skin colour, thickness, and other characteristics, human skin susceptibility to UV radiation varies.
A minimum erythema dose (MED) is defined as the quantity of UV radiation that generates minimal erythema (sunburn or redness produced by capillary engorgement) of an individual's skin during a few hours of exposure and is used to calculate the optimum dosage of UV light to deliver to a patient.
There is currently no simple technique to identify an acceptable UV dose for therapeutic or research purposes without undergoing official MED testing, which requires hours of observation afterwards, or informal trial and error testing, which risks under- or over-dosing. There are, however, a variety of possibilities for various parts of MED testing.
