Many rashes and itches worsen as winter approaches. The skin becomes dry, which is not helped by having to wear plenty of clothes. Phototherapy is a method in which the skin is exposed to sufficient amounts of the sun’s UV radiation to relieve skin problems. We use a narrowband UVB lamp, which is the recommended treatment for atopic dermatitis and psoriasis in line with Current Care Guidelines. It is also used for the treatment of itching, folliculitis, lichen ruber, prurigo nodularis, hives and vitiligo.

Phototherapy is a drug-free method of treating rashes and itching

Narrowband UVB treatment consists of the patient being selectively exposed to a wavelength of 311 nanometres, found in natural light, which relieves skin disease symptoms. UVA rays, which penetrate deeper into the skin and age it, are absent.

The treatment is based on limiting the infection and supporting the natural functioning of the skin. UVB light is primarily absorbed by the epidermis, making it thicker and thereby preventing the skin from drying. Light increases the production of ceramides, i.e. lipid molecules in the stratum corneum, which prevents water from evaporating and the skin from drying.

Only a few minutes at a time

The UV light emitted by phototherapy lamps is so powerful and sensitive that light skin can burn as it would in the sun. Phototherapy is always performed under the supervision of a professional and the amount of light is adjusted to individual needs. UVB phototherapy is usually given in series of at least 15 or 20 sessions, and the exposure period is extended gradually as tolerance increases and the symptoms subside. The first treatment sessions can be very short indeed; as the treatments progress, they still involve a maximum of a few minutes.

In most cases, the entire body is exposed to the treatment. The phototherapy equipment resembles a walk-in closet full of fluorescent lamps. The patient has protective eyewear, and the genital area is covered. In certain cases, treatment may be limited to the scalp, the palms, or the soles of the feet. Phototherapy is safe and suitable during pregnancy and childhood.

A referral to phototherapy

Phototherapy must always be prescribed by a doctor. You can obtain a referral from a GP, occupational health doctor or specialist. This means that you do not need a referral from a dermatologist for phototherapy. The treatment is administered by a nurse specialising in the phototherapy equipment and recommended doses.

The Ihosairaala uses narrowband UVB equipment. We have several experts specialising in phototherapy, who will be happy to help you with any phototherapy issues.
