Possible Complications
Problems are rare, but all procedures have some risk. The doctor
will go over some problems that could happen, such as:
- Burns or blisters that are similar to a sunburn
- Nausea
- Premature aging of the skin, such as wrinkling and dryness
- Skin cancer
- The skin condition worsens
- Cataracts
The risk of problems may be raised in people with chronic health
issues, such as liver disease.
Reasons for Procedure
UV light shuts down immune system cells in the skin. It can help in skin conditions that are caused by an overreaction of the immune system.
Skin conditions that are treated with phototherapy include:
- Psoriasis —a skin disorder that causes
red, silvery, scaly patches on the skin
- Atopic dermatitis —eczema, an itchy, red
skin condition, or dermatitis due to allergies
- Cutaneous T-Cell Lymphoma—a type of lymphoma confined to the skin
- Vitiligo —a skin disorder where normal
skin pigment is lost because pigment producing cells are destroyed by the immune
system
- Lichen
planus —an inflammatory skin condition
- Alopecia
areata —areas of baldness
- Pityriasis
rosea —a skin rash that is common in children and young adults
- A rare form of Crigler-Najjar syndrome
What to Expect
Prior to Procedure
The care team may meet with you to talk about:
- Any allergies you have
- Current medicines, vitamins, herbs, and supplements that you take and if you need
to stop taking them before surgery
Description of the Procedure
You will be asked to remove any clothes that cover the skin
being treated. Areas that do not need treatment will be covered and protected, such
as with sunscreen and eye goggles. If you are having PUVA treatment, psoralen will be
given before it starts.
Large areas may be treated in a treatment unit that you will
stand inside. Smaller areas may be treated with a smaller unit that will focus a
laser light on the specific area.
How Long Will It Take?
Sessions will vary in length from a few seconds to a few
minutes. It will depend on your skin type and the strength of the light. Treatments
rarely last longer than a few minutes. Several treatments will be needed each week
until the skin is clear. The length of treatment will depend on the type of
phototherapy. Additional treatments may be needed to maintain results.
Will It Hurt?
You may feel a warm sensation on your skin, similar to a mild
sunburn. Medicine can help with discomfort after treatment.
Post-procedure Care
At the Hospital
You can leave after the procedure is done.
At Home
Normal activities can be resumed after treatment. Natural
sunlight will need to be avoided by wearing protective clothing, a hat, sunscreen,
and sunglasses.
Problems to Look Out For
Call the doctor if you have:
- Signs of infection, such as fever and chills
- Redness around skin sores or any leakage
- Severe skin burning, pain, or blistering
- New or worsening symptoms
If you think you have an emergency, call for medical help right away.
