Frequently Asked Questions

  • How long do I need to wait before I begin to see results?

    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.

  • My skin turned red after my treatments. What do I do?

    Occasional or temporary redness may be normal if it resolves by the next treatment time. If your redness is sustained, ask your doctor if you should reduce your treatment times.

  • 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.)

  • If my device is located in a cold room, do I need to allow time for the lamps to warm up?

    With a dosimetry machine, there is no real advantage to allowing your machine to warm up first. In situations where a machine is kept in a very cold environment such as a garage, a 5-minute warmup may allow faster treatment times.

  • Should I treat for the same amount of time that I treated for in the doctor’s office?

    Every device has a different level of therapeutic output. Follow your doctor’s directions for dosing advice. If you have questions about how to program your machine to deliver the doses your doctor provides, please contact technical support.

  • What is a good room to do my treatments in?

    Choose a dry, enclosed room where others will not be exposed to the light. Optimum treatment times and lamp life will occur when the machine is kept in a room temperature area that is neither extremely hot nor cold.

  • I just received my 7 Series. How should I unbox/uncrate it?

    We have created a video tutorial to help you uncrate and set up your 7 Series:

  • My unit is due for a cleaning and calibration. What should I do?

    Please contact our service team. One of our friendly representatives will be in touch with your preventative maintenance options.

  • I’m seeing good results with my phototherapy treatments, other than my face. Is it possible the light is working everywhere except for my face?

    For best results, make sure all makeup or anything covering your face has been removed. Additionally, since the face is almost always exposed to light, it may have “photoadaptation,” meaning it has become used to this light exposure. Ask your dermatologist if you could benefit from a higher treatment dosage.

  • Why is my treatment time/dose at my doctor's office different than my treatment time/dose using my home device?
    This is because the output of your doctor's device is different than the output of your home device. To be safe, your doctor will typically prescribe a lower starting time/dose for use on your home device, then recommend an increase back up to what you were receiving in their office.
