Phototherapy or light therapy, involves exposing the skin to ultraviolet light on a regular basis and under medical supervision. The skin may redden and itch from exposure to the UVB light. The most common short-term side effects of PUVA are nausea, itching and redness of the skin. This is helpful in treating psoriasis, which causes skin cells to grow too rapidly. There are two types of ultraviolet (UV) light therapy: ultraviolet B (UVB) and ultraviolet A (UVA).Phototherapy may be given in a variety of places, such as in a hospital or doctor’s office, in your home (UVB), or at a. Then you will go into a booth and be exposed to the UV light. Using two kinds of treatment is called combination therapy. Three common combination therapies are:. The most common immediate side effect of UVB phototherapy is a mild sunburn reaction. This may be more likely if the person being treated has been using other medications or herbal supplements which can cause sensitivity to light. This sunburn reaction is usually not serious and the phototherapist will adjust the dose of the next treatment or postpone treatments until the redness has settled.
UVB phototherapy refers to irradiation with short wave ultraviolet radiation. Increasing doses of UVB are given each exposure (three to five times weekly), aiming to turn the skin slightly pink. Psoriasis is a common inherited skin disorder, which may vary considerably in extent and severity. Exposure to UV light (A or B) can cause skin damage, premature ageing and increases the risk of skin cancer. Phototherapy is the original psoriasis treatment. During the treatment patients are exposed to the light for just a few seconds at first, and the exposure time is gradually increased to several minutes per treatment.
Ultraviolet light therapy or ultraviolet phototherapy is a form of treatment for certain skin disorders including atopic skin disorder and vitiligo when used with psoralen to form the PUVA treatment. This treatment is similar to the light from good quality solariums but differs from the mainly UVB ultraviolet band used to treat psoriasis. Typical treatment regimens involve short exposure to UVB rays 3 to 5 times a week at a hospital or clinic, and repeated sessions may be required before results are noticeable. Psoriasis treatments can be divided into three main types: topical treatments, light therapy and systemic medications. The most common side effect is skin irritation. The simplest and easiest form of phototherapy involves exposing your skin to controlled amounts of natural sunlight. When exposed to UV rays in sunlight or artificial light, the activated T cells in the skin die. One group found that natural sun exposure led to a decrease in Th17 inflammatory cytokine expression, specifically IL-17 and IL-23, in the psoriatic lesions of three out of four patients investigated in the study. More specifically, UV light is thought to induce clustering and internalization of TNF, IL-1, and EGF receptors on cell surfaces,36 and activate CD95 surface molecules,37 both of which trigger pathways that lead to programmed cell death.

Phototherapy (light therapy): Ultraviolet (UVL) light, a portion of the solar spectrum with wavelengths between 290-400 nm, can have beneficial effects on psoriatic skin presumably by altering certain immune functions. Although normal sunlight contains these wavelengths, self-exposure to sunlight must be done in under controlled conditions to minimize burns. Treatment with psoralen and UVA is referred to as PUVA. They should reduce exposure to natural sunlight during this time. Skin reactions, including itching, sunburn, and blistering, are common. Common treatments include topical medications that reduce inflammation, or oral medications that suppress your immune system. Phototherapy is a treatment for psoriasis that uses natural or synthetic lights. The nutrient, as well as the UV rays from light exposure, can help clear or prevent psoriasis plaques. Psoriasis is a chronic, recurring disease that causes one or more raised, red patches that have silvery scales and a distinct border between the patch and normal skin. Controlled exposure to certain bands of the light spectrum can ease psoriasis symptoms. Phototherapy, also known as light therapy, treats psoriasis by exposing skin to ultraviolet light on a regular basis under a doctor’s supervision. NB-UVB is the most common option because its narrower wavelength spectrum affords greater safety and efficacy, especially for plaque psoriasis. The term phototherapy literally means the use of light to treat medical conditions. UVB is used to treat common skin conditions such as psoriasis, atopic eczema, other forms of dermatitis, polymorphic light eruption, generalised itching, pityriasis lichenoides, cutaneous T cell lymphoma, lichen planus, vitiligo and other less common conditions. The first few treatments will often last less than one minute, and the duration of exposure to ultraviolet light will gradually increase, up to a number of minutes.
Ultraviolet Light Therapy
Cortisone creams and ointments are the most common treatments for psoriasis. Doctors use these with phototherapy. Phototherapy is a procedure in which skin is carefully exposed to natural or artificial ultraviolet (UV) light. Phototherapy lamps for skin treatment. FDA has cleared Philips Narrowband phototherapy lamps for the treatment of Psoriasis and Vitiligo and has cleared Philips Broadband phototherapy lamps for the treatment of Psoriasis. In normal physiological circumstances, this unconjugated bilirubin is bound to albumin and transported to the liver where it is converted by glucuronyltransferase into the water-soluble conjugated form and excreted in the bile. Devices to produce artificial light for the treatment of psoriasis have been in use for over 60 years and today there is a phototherapy clinic in most cities, usually in a hosptital or a dermatologist’s office. As with natural sunlight, repeated exposure to ultraviolet light can cause premature aging of the skin and skin cancer. Under normal home phototherapy usage, the bulbs have a useful life of at least three to five years, and as many as ten years. UVB (ultraviolet B light) is the most common form of phototherapy used to treat various skin disease, including psoriasis, eczema and itching. You will be exposed to this high energy UV light for a varying length of time. This treatment is NOT A CURE, but can effectively control or improve your disease.
How long has ultraviolet phototherapy treatment been used? Devices to produce artificial light for the treatment of psoriasis have been in use for over 60 years and today there is a phototherapy clinic in most cities, usually in a hosptital or a dermatologist’s office. Have you ever deliberately taken sun exposure to improve your skin? Volt grounded (three prong) electrical outlet common to almost all homes in North America. Our phototherapy treatment unit offers a broad range of ultraviolet light services for chronic skin disorders such as psoriasis, vitiligo and atopic dermatitis, and other light-responsive conditions such as contact dermatitis, mycosis fungoides, actinic keratoses and acne. Precancerous or cancerous skin cells take up and retain the drug better and longer than normal cells allowing selective destruction of those cells upon exposure to the light source. If you have psoriasis, eczema or other skin diseases, your doctor may recommend treatment with phototherapy. This is a common occurrence and will typically resolve within several hours or days following initial treatment. Prolonged exposure to UV light during phototherapy treatment may burn or damage the upper layer of skin. You are exposed to the light until it causes the skin to turn slightly pink. When the skin no longer turns pink in the 24 hours after a treatment, the exposure time is increased. A laser treatment for psoriasis (excimer laser) also uses UVB light. Excimer laser works well for psoriasis that has been hard to treat on the elbows and knees.
