UVB therapy
UVB therapy is given in the light cabinet using UVB bulbs. You do not need to take any medication beforehand for this. Nor are you extra sensitive to UV light afterwards, as is the case with PUVA therapy.
What does UVB therapy involve?
The dermatologist determines the light therapy plan on the basis of your skin colour. The exposure time is increased gradually to avoid burning. The first sessions usually last no longer than a few seconds.
The first time you will be assisted by a nurse, who will explain the procedure to you. For the following sessions, the nurse will contact you in the waiting room as soon as you can go to the cabinet.
How long does the therapy take?
You have to undergo the therapy 3 times per week for an average of 2 to 3 months. The therapy cannot be provided on three successive days in order to avoid burning the skin.
What should you watch out for during the treatment?
- UV light can damage your eyes. So you should always wear protective goggles during the treatment.
- Some drugs make you very sensitive to light. So always discuss the medication that you take with your dermatologist beforehand.
