About Narrowband UVB Phototherapy

What is Narrowband UVB?

Narrowband UVB (n-UVB) phototherapy uses a specific wavelength of ultraviolet light (around 311 nanometres) that has been widely studied and used in clinical dermatology settings for many years.

This wavelength is commonly associated with supporting the management of certain inflammatory skin conditions by helping to slow excessive skin cell turnover and reduce inflammation. Narrowband UVB is distinct from cosmetic tanning lamps and uses a different light spectrum.

How Narrowband UVB Phototherapy Is Commonly Used

In hospital and dermatology settings, narrowband UVB phototherapy is typically delivered in short, controlled exposure sessions. Treatment schedules are adjusted gradually over time based on individual skin tolerance and response.

Sessions are usually spaced out to allow the skin time to recover between exposures. This cautious, gradual approach is widely recognised as important for safe use.

Many healthcare providers include narrowband UVB phototherapy as part of a broader management approach for conditions such as:

  • Psoriasis
  • Eczema
  • Vitiligo

Home Phototherapy 

Some individuals explore home phototherapy as a way to continue or complement treatment outside of a clinical environment, where appropriate and under medical guidance.

General considerations may include:

  • Greater flexibility around scheduling
  • Reduced need for frequent clinic visits
  • The ability to maintain consistency over time
  • Convenience during flare-ups, where appropriate

Home phototherapy is not a replacement for medical care and may not be suitable for everyone. Individual suitability and treatment plans should always be discussed with a qualified healthcare professional.
