Narrowband UVB (NB-UVB) Phototherapy: A Complete Guide for Skin Treatment

What Is Narrowband UVB?

Narrowband UVB (NB-UVB) is a medical light therapy that uses ultraviolet B light with a narrow wavelength range between 311–312 nm to treat various skin conditions. This therapy is more effective and safer than broadband UVB or PUVA (Psoralen + UVA) in managing inflammatory skin diseases.

How Does NB-UVB Work?

NB-UVB works by targeting problem skin cells, reducing inflammation, and slowing down the excessive growth of skin cells. In conditions like psoriasis and vitiligo, NB-UVB can stimulate melanocyte activity to promote repigmentation.

Benefits of NB-UVB

• Psoriasis: Reduces inflammation and skin cell proliferation.
• Vitiligo: Stimulates repigmentation of depigmented skin areas.
• Eczema & Dermatitis: Reduces itching and inflammation.
• Alopecia Areata: Promotes hair growth in some cases.
• Safety: NB-UVB has a better safety profile compared to PUVA, with a lower risk of skin cancer.

Side Effects and Risks

Short-Term Side Effects

• Redness or a burning sensation on the skin.
• Dry and itchy skin.
• Sunburn-like reactions.
• Reactivation of herpes simplex (e.g., cold sores).
• Increased pigmentation in treated areas.

Long-Term Side Effects

• Premature aging of the skin.
• Increased risk of skin cancer with repeated use.

Home Use of NB-UVB

NB-UVB can be used at home with light therapy devices such as handheld lamps or UV combs. These devices allow localized treatment of areas like the face, hands, or scalp. However, full-body treatments typically require a full therapy unit available at dermatology clinics.

Duration and Frequency of Treatment

• Frequency: 2–3 times per week.
• Duration: Each session lasts a few minutes.
• Results Time: Improvements may be visible within 3–8 weeks, depending on the skin condition.

Who Is Suitable for NB-UVB?

NB-UVB is suitable for individuals with skin conditions like psoriasis, vitiligo, eczema, and atopic dermatitis who do not respond to topical treatments. However, it is not recommended for those with photosensitivity disorders, lupus, or porphyria.

Conclusion

NB-UVB is an effective and safe therapy for various inflammatory skin conditions. With proper use and medical supervision, this therapy can lead to significant improvements in your skin condition.
