UV Light (Phototherapy)

---

Phototherapy, also known as ultraviolet (UV) light therapy, is a widely used dermatological treatment for a range of inflammatory and immune-mediated skin conditions. It works by delivering controlled exposure to specific wavelengths of ultraviolet light, which can help reduce inflammation, slow excessive skin cell turnover and relieve symptoms such as itching and irritation.

At Clayton Dermatology, phototherapy is commonly used in the management of conditions including psoriasis, eczema and other chronic inflammatory skin disorders that may not respond sufficiently to topical or standard therapies.

Phototherapy involves exposing the skin to carefully measured doses of ultraviolet light in a specialised clinical setting. Treatment is delivered under the supervision of dermatology professionals to ensure it is both safe and effective for each individual patient.

Two commonly used forms of phototherapy include:

• Narrowband UVB therapy – frequently used for conditions such as psoriasis, eczema and other widespread inflammatory skin diseases
• PUVA therapy – may be used in selected cases, including treatment of certain areas such as the hands and feet

The choice of therapy depends on the type, severity and distribution of the skin condition being treated.

Phototherapy is typically delivered as a course of treatment over several weeks. Sessions are usually scheduled multiple times per week, with each appointment being relatively short in duration.

The dose of ultraviolet light is carefully adjusted based on the patient’s skin type, response to treatment and underlying condition. Over time, many patients experience a noticeable improvement in symptoms such as redness, scaling and itching.

Because ultraviolet light can affect the skin if not used appropriately, phototherapy must always be administered under medical supervision. Dermatologists closely monitor progress throughout the treatment course and make adjustments as needed to optimise outcomes and minimise risks.

For patients with chronic skin conditions that have not responded well to other treatments, phototherapy may be a valuable and effective option for improving long-term skin control.
