Phototherapy Treatment

UVB phototherapy is a medical treatment that uses short-wave ultraviolet radiation (UVB) to manage a variety of inflammatory skin conditions. During treatment, the patient stands in a specially designed cabinet equipped with fluorescent light tubes that emit therapeutic UVB rays. For full-body therapy, patients are undressed, allowing the light to reach affected areas evenly.

Initially, broadband UVB was the standard approach, but narrowband UVB phototherapy (311 nm) is now preferred due to its higher efficacy and safety profile. Treatments are typically administered two to three times per week. The dose of UVB is gradually increased with each session, depending on the patient's tolerance and skin response. A treatment course continues until the skin condition clears, the maximum number of sessions is reached, or the therapy is deemed ineffective.

The effects of UVB light resemble those of natural sunlight. While controlled doses offer therapeutic benefits, excessive exposure can accelerate skin aging and increase the risk of skin cancer.

Psoriasis is a chronic and often inherited skin disorder characterised by thick, scaly plaques that may vary in severity and extent. UVB phototherapy is frequently recommended for patients with widespread psoriasis. However, it may not be suitable for individuals with fair or photosensitive skin, or for those whose condition worsens with sun exposure.

Most patients undergo three treatment sessions per week, beginning with very short exposures, lasting only a few seconds, and gradually increasing based on individual response. Approximately 24 sessions are typically required to achieve significant improvement or clearance. Once the skin clears, treatments are paused, and remission can last several months. However, psoriasis may return over time, necessitating additional maintenance sessions.

UVB phototherapy is also highly effective in managing eczema (atopic dermatitis) and other inflammatory conditions such as vitiligo and pityriasis lichenoides. The duration and frequency of sessions are customised for each patient, depending on the severity of the disease and skin sensitivity. A full course of treatment may extend beyond 24 sessions. Consistency is key; regular attendance is essential to achieving optimal results.

Before beginning treatment, patients should inform their dermatologist of any existing medical conditions, such as eye diseases, and provide a complete list of medications, as some drugs can increase sensitivity to UV light and cause burning. During the treatment period, patients should avoid applying ointments, perfumes, or coal tar products, as well as minimise sun exposure on both treatment and non-treatment days. The regular use of broad-spectrum sunscreen on the face and hands is strongly advised.

At the Centre for Medical and Surgical Dermatology in Pickering, led by Dr. Maksym Breslavets, patients receive personalised and evidence-based care tailored to their skin condition and lifestyle. Each treatment plan is customised following a thorough skin assessment to ensure the most suitable approach for every individual.
