Phototherapy

How does phototherapy treatment work?

Phototherapy treatment uses various wavelengths of artificial ultraviolet (UV) light to trigger natural processes that reduce inflammation and prevent skin cells from growing too quickly. Regularly exposing the affected area(s) to this type of light can have many benefits for your skin. Other names for phototherapy include light therapy and heliotherapy.

The main types of phototherapy are:

  • Broadband UVB.
  • Narrowband UVB
  • PUVA – A combination of UVA and psoralen (a plant-based medicine that makes your skin more sensitive to light)

Your Forefront dermatologist can explain the different types of phototherapy and which one is best for you.

What conditions does phototherapy treat?

Forefront providers use phototherapy to treat a variety of skin conditions, including:

Eczema. Eczema is a skin condition that causes dry, itchy, and inflamed skin. Dermatologists use phototherapy to treat many forms of eczema because of its ability to reduce itchiness and inflammation. Phototherapy can be used for localized eczema (in one area, such as your hands or feet) or widespread eczema (all over your body). The most common type of phototherapy used to treat eczema is narrowband UVB.

Psoriasis. Psoriasis is an autoimmune disorder that causes lesions or inflamed scaly patches on your skin. Dermatologists prescribe phototherapy for psoriasis because it can help suppress an overly active immune system and slow rapidly growing skin cells. Phototherapy often provides itch and inflammation relief for psoriasis patients as well.

Vitiligo. Vitiligo causes cells that produce melanin to stop functioning, leading to patches of skin that lose pigment. Usually, the condition is only cosmetic. Phototherapy with narrow band ultraviolet B (UVB) has been shown to stop or slow the progression of active vitiligo.

Atopic dermatitis. Atopic dermatitis is a persistent skin condition that can make the skin red, dry, and very itchy. Phototherapy may provide relief when topical solutions don’t work.

Cutaneous T-cell lymphoma. This rare form of skin cancer responds well to phototherapy, with a 60-90% effectiveness rate depending on the stage, thickness of lesions, and baseline skin color. Remissions have been documented after completing treatment.

Outside the dermatologist’s office, phototherapy can also help treat mood disorders, sleep disorders, other types of cancer, and more.

What can I expect from phototherapy treatment?

First, your provider will give you protective eyewear to cover your eyes, and sunscreen for whatever areas that will be exposed to UV lights. You may also need additional personal protective equipment depending on the location of your therapy.

If you have large areas of skin being treated, you will likely be in a stand-up booth. Smaller areas of skin will be treated with a handheld wand while you are sitting or lying on a table. During and after treatment, you may feel a warm sensation on your skin, similar to a mild sunburn. Your Forefront dermatologist can recommend medication if you experience discomfort.

How long does phototherapy take?

The length of your phototherapy treatment will depend on your skin type, the strength of the light, and other factors. The first treatment is usually very short – it could be just a few seconds, especially if you have lighter skin. Throughout the course of your treatment, each phototherapy session rarely lasts longer than a few minutes (regardless of skin tone).

The number of sessions you need will depend on the type of phototherapy being provided. For example:

  • Broadband UVB requires about 3-5 sessions each week
  • Narrowband UVB requires about 2-3 sessions each week
  • PUVA requires about 25 sessions over a 2-3 month period

In most cases, phototherapy treatment will continue until your skin is clear. Some patients also need occasional maintenance treatment. The key to success with phototherapy treatment is consistency.
