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.

  • Are there medications I shouldn't take while treating with phototherapy?

    It is important to know that some topicals may actually hinder treatment. For example, some lotions contain UV absorbing ingredients similar to those used in sunscreens and may block much of the benefit of phototherapy treatment.

    Other topicals and medications may photosensitize your skin. Watch out for lotions containing photosensitizing agents or essential oils such as lime, lemon, or orange. Such ingredients could cause an unexpected erythemal reaction when exposed to the ultraviolet energy delivered during a phototherapy treatment. In addition, coal tar, psoralens, and retinoids will consistently photosensitive your skin to UV light.  For a detailed list of photosensitizers, visit this link: https://www.daavlin.com/dont-see-red-know-these-photosensitizers/. We recommend speaking with your doctor about topicals and medications that may impact your phototherapy treatments.

  • 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.

  • How can I determine how many exposures I have left?
