Narrowband UVB lamps emit wavelengths between 311-313 nanometers, which is the specific range considered most effective. As the rays penetrate bare skin, they slow the growth of affected skin cells and decrease inflammation. This narrow band UVB wavelength is the sweet spot for the best efficacy with minimal side effects. ![Smiling woman applying Narrow Band UVB Phototherapy.](https://bhskin.com/wp-content/uploads/2020/04/DSC-8456-1.jpeg) ## Four Benefits of Narrowband UVB Phototherapy ### #1 Results that Last Patients that visit our LA clinics often over time notice that their results last 6 months or more.

Our award-winning team will also assess your skin type to determine the best wavelength of light to use for you. Some skin types burn or tan easier than others. Prior to your treatment, you’ll want to avoid the sun as much as possible. Too much sun could significantly increase your risk of burning with this treatment. ### During The Treatment Because of the bright light, you’ll be given protective glasses to wear. It’s also very likely that you’ll have an ointment applied prior to the process. Most patients require multiple treatments with UVB narrow band light therapy, often up to 2 to 5 visits per week.
