Narrow Band UVB (NB-UVB) phototherapy is a specialised light therapy that uses a specific wavelength of ultraviolet light (311-313 nm) to treat various skin conditions. This wavelength is optimal for reducing skin inflammation and slowing down the abnormal skin cell production associated with certain dermatological conditions. During treatment, the affected skin is exposed to controlled doses of NB-UVB light, which helps improve symptoms while minimising the risks associated with broader UV exposure.
The therapy is administered in a clinical setting using specialised light units. Patients undergo multiple sessions over several weeks, with the frequency and duration tailored to their specific condition and skin type.
NB-UVB phototherapy is an effective treatment option for a variety of skin conditions, including:
Psoriasis
Reduces scaling, itching, and plaque formation by slowing down excessive skin cell turnover.
Eczema (Atopic Dermatitis)
Alleviates inflammation and itching in moderate to severe cases.
Vitiligo
Promotes re-pigmentation by stimulating melanocyte activity.
Pruritus (Itching)
Provides relief for chronic itching conditions, including those caused by kidney disease or other systemic disorders.
Cutaneous T-Cell Lymphoma
Slows the growth of abnormal T-cells in early-stage disease.
Polymorphic Light Eruption (PLE)
Improves tolerance to sunlight by desensitising the skin.
Lichen Planus
Helps reduce inflammation and skin lesions.
Benefits:
- Effective Symptom Management
Provides significant relief for chronic skin conditions that are unresponsive to other treatments.
- Non-Invasive
A safe and painless procedure with no need for surgery or systemic medications.
- Targeted Therapy
Reduces inflammation and abnormal skin cell growth without affecting healthy skin.
- Minimal Downtime
Patients can resume their normal activities immediately after treatment.
Risks:
- Temporary Redness and Dryness
Mild skin irritation or dryness may occur during and after treatment.
- Sunburn-Like Reaction
Overexposure during treatment can lead to burns.
- Long-Term Risks
Prolonged or excessive use may increase the risk of skin aging and, in rare cases, skin cancer.
- Not Suitable for All Patients
NB-UVB is not recommended for individuals with a history of photosensitivity or certain medical conditions.
Patients undergoing NB-UVB phototherapy should follow their dermatologist’s instructions carefully and use protective measures such as moisturising and avoiding unprotected sun exposure to optimise results and minimise risks.
