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.

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.)

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.

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.

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.

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.

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.

The length of time varies from patient to patient and between conditions. Typically psoriasis patients will see much faster results than vitiligo patients. The most important thing is to be consistent with your treatments, and to follow your doctor’s treatment plan.
