Treatment Details
What happens before a phototherapy procedure?
Before your phototherapy procedure, your provider will set up the equipment in a hospital or a treatment center. They’ll give you protective eyewear to cover your eyes. You may need additional personal protective equipment depending on the location of your therapy, like a face shield or a blanket to cover parts of your body that aren’t receiving treatment. Your provider will give you sunscreen to put on your skin before your procedure. If you’re only getting treatment on part of your body, they’ll give you instructions on how and where you should apply the sunscreen. You may need to remove some or all of your clothing for this procedure depending on what’s being treated.
"VSports" What happens during a phototherapy procedure?
During a phototherapy procedure, your provider will verify that you’re wearing your personal protective equipment, like eye protection, before turning on the ultraviolet light. The way that the UV light passes on your skin is unique to each type of treatment:
- UVB light: You’ll stand in a box-like structure, similar to an upright tanning bed, where a light source will pass over your skin. Once you’re inside, the lights will turn on for a set amount of time by your provider. If you’re only treating a small section of your skin, you’ll sit or lie down on a table and your provider will wave a wand with a light in it across your skin.
- UVA light: The procedure is similar to UVB. Sometimes, medications are used to help the treatment work better. Psoralen is a plant chemical that makes your skin more sensitive to UVA light. If you have psoralen UVA treatment, your provider will begin by letting you soak in a bath that contains psoralen or give you psoralen to take by mouth or put on your skin before your treatment.
- Excimer laser light: Lasers deliver more focused ultraviolet light to smaller areas of your body. After exposing the area to be treated, your provider will have you lie on a table before moving the laser light over a small area of your skin that needs treatment.

How long does a phototherapy procedure take?
Phototherapy procedure times vary depending on the size of your treatment area and the strength of UV light your provider uses. Repeated treatments are needed for the best results. Your first session could last a few seconds and your final session could last a few minutes with UVB therapy and up to an hour for UVA therapy. The length of time you’re treated and the total number of treatments you need can vary greatly depending on the disease and your skin. Your provider will help figure out your personal treatment plan.
What happens after a phototherapy procedure?
After a phototherapy procedure, your provider will give you instructions on how you can protect your skin, which could include:
- Wearing sunscreen on the treated areas of your skin and/or clothing to protect your skin from the sun.
- Wearing eye protection when outdoors.
- Using a moisturizer daily to prevent dry skin.
- Avoiding sun exposure and avoiding tanning beds, which could increase your chances of a burn.

Recovery and Outlook
What is the recovery time for a phototherapy procedure?
After a phototherapy procedure, you can immediately go back to your normal activities. It takes multiple treatments to see results on your skin. Most people see improvements to their skin after six to eight treatments, but it could take between 15 and 25 treatments until you see results. Certain conditions treated with UVA light take much longer to treat.
Your provider will recommend you take steps to protect your skin from further UV exposure, especially from the sun, after treatment. You may experience some skin redness or hyperpigmentation, where your skin appears darker after treatment, this may go away after 24 hours. If you feel a burning sensation on your skin that lasts more than a couple of days after treatment, contact your provider.

Additional Common Questions
Can jaundice come back after phototherapy?
It’s common for newborns and babies to have jaundice even after phototherapy treatment. High levels of bilirubin (hyperbilirubinemia) in your baby’s blood cause jaundice. Too much bilirubin can cause permanent brain damage (kernicterus) if it’s not treated. Babies can get a skin test to see if they have too much bilirubin, and then a blood test to determine the cause of their jaundice. Your provider will decide if UV treatment is necessary and then they’ll keep checking the bilirubin level to be sure it’s getting better. After treatment, your baby will have bilirubin checked to be sure it doesn’t get high again.
Can I do phototherapy at home?
Yes. If your newborn has jaundice and no other health complications, your provider might offer a treatment plan that lets you do phototherapy at home. You can use a phototherapy lamp or fiber-optic blanket (Biliblanket®) safely while staying in the comfort of your own home.
Some adults also use at-home phototherapy. People who experience seasonal affective disorder (SAD) can have depressed mood during the winter, when there’s less sun. UV lamps replicate sunlight and are used to make your body think that it’s warmer and sunnier than it really is. This helps your body release serotonin, which is a neurotransmitter that can improve your mood. Be sure to look for 10,000 lux lamps if you use one for SAD.
During at-home therapy, you and/or your baby must wear eye protection to prevent eye damage from the light.
Do glutathione patches improve the effects of phototherapy?
Glutathione is an antioxidant that protects your cells from damage when they’re under stress. Some studies suggest that oral glutathione supplements or the topical glutathione patch can prevent damage to your cells caused by ultraviolet light. More research is necessary to determine if glutathione is safe and effective at preventing damage to your cells.
