UV Phototherapy
Narrowband phototherapy is a safe and effective treatment for autoimmune skin diseases and is considered a first-line treatment for many conditions such as psoriasis, vitiligo and eczema. It’s safe enough for pregnant women and children to use, and has none of the serious side effects associated with competing biological drug therapies.

What is Phototherapy?

What is Phototherapy_Header

Phototherapy is the use of light to treat psoriasis, vitiligo, and other skin disorders. During treatments, the skin is exposed to a special type of light which is emitted by a medical device commonly referred to as a phototherapy unit.

These units range from hand-held and table-top devices for spot treatment of small areas to cabinet or “walk-in” units for patients requiring full body treatment.

Phototherapy vs. Biologics

Patient_Main Header

While biological drug therapies have become very popular, it is important to evaluate their safety. Many of these medications have had numerous adverse side effects and deaths where the drug was listed as the primary suspected cause.

In addition to the potential side effects, biologics also carry a much larger entry cost burden to the patient and provider, whereas, phototherapy is a one-time purchase.

Frequently Asked Questions

  • Are my lamps covered by a warranty?

    Daavlin warrants its lamps for sixty (60) days against defects in material and workmanship and to operate at the time of initial installation in an electrical circuit having the correct characteristics for proper lamp operation. No warranty is made as to useful lamp life or as to reduction in ultraviolet output due to any cause.

  • Can I expose my “healthy” skin to the light or do I need to cover it?

    It’s usually best to keep uninvolved skin covered with clothing or sunscreen during your treatments, but follow your doctor’s advice. The most important thing about covering “healthy” skin is to be consistent, and always use the same covering techniques for each treatment. (External genitalia should be covered during PUVA therapy.)

  • Can I return my phototherapy device to Daavlin?

    No, Daavlin does not accept returns for phototherapy devices. Our phototherapy devices are prescribed devices—similar to a prescription drug. We are not able to resell used products; therefore, we do not have a buy-back program.

  • Can I use my device in different countries?

    Every Daavlin phototherapy device has a label near the power inlet with a voltage and frequency specification. If the voltage of the country that you are traveling to matches the label, you may use it. If you would like to use your device in countries with a different voltage, contact Daavlin technical support for more information. Depending on the exact machine you have, there are a range of possible solutions.

  • Do I need a prescription to purchase a phototherapy device?

    Yes, the purchase of home phototherapy devices or new lamps requires a prescription from your doctor. If you need help finding a doctor in your area, please take a look at our list of dermatology clinics.

  • Does my phototherapy device fade my clothing?

    Technically, your phototherapy device will fade materials—similar to how sunlight fades clothing. However, it takes years of extended exposure to see a noticeable difference.

  • How can I check on the status of my order?

    If you are a patient, please contact your patient representative to check the status of your order. Clinical customers should contact their account representative to check the status of an order or installation.
