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.

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.

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.)

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.

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.

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.

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.
