What is phototherapy?
Phototherapy is a highly effective physical therapy or treatment method in which non-ionizing ultraviolet (UV) radiation in various wavelengths, visible light (biolamp) or infrared radiation is applied. In our clinic, we use 311 nm UVB phototherapy (narrowband, monochromatic), which is currently the latest trend and the most commonly used type of phototherapy with a good safety profile, even in children. A full-body booth or a localized radiation source - e.g. UV comb - is used to treat manifestations in the capillitium. Phototherapy will replenish the body's own natural abilities to renew the skin and minimize visible signs of aging.
What is the treatment regimen for phototherapy?
In the first place, a consultation with a dermatologist is necessary, who will take into account the patient's phototype, anamnestic tolerance and reaction to UV radiation. The treatment regimen of 311 nm UVB phototherapy consists of a cycle of 15-25 irradiations at an intensity of 2-3 times a week, under constant supervision of a physician. Radiation doses are tailored to the individual patient's requirements and diagnosis, increasing the duration of exposure over time. Cycles of phototherapy can be administered twice a year, up to the maximum effective combined dose. If there is no complete resorption of symptoms even after 3-6 weeks, it is possible to continue the so-called maintenance phototherapy twice a week for 1 month and once a week for another month.
What are the indications for 311 nm UVB phototherapy?
Phototherapy has a local immunomodulatory to immunosuppressive effect on the skin. It is because of these effects that phototherapy is used for various skin diseases:
- eczema - not in the acute stage
- pityriasis rosea
- keratosis follicularis
What are the contraindications to phototherapy?
- UVB phototherapy is contraindicated in the presence of any skin tumours - malignant melanoma or non-melanoma skin tumours (squamous and basal cell carcinoma), dysplastic nevus syndrome
- skin provoked by the sun, so-called photodermatosis, when taking photosensitizing drugs and light polymorphic eruptions
- it is unsuitable for people suffering from claustrophobia
- severe cardiovascular disease (overheating, long standing in the cabin)
- protection of the eyes and some parts of the body during irradiation (e.g. genital area, covering pigmented nevi with paste) is essential
- children under 3 years of age should not sunbathe or undergo phototherapy
