Photo-Therapy To Manage Psoriasis: All That You Need To Know

If your skin remains itchy, scaly, and red, you can try Photo-therapy. This is a type of psoriasis treatment that may make the pain and itchiness of the condition go away. It often uses ultraviolet (UV) light, which reduces inflammation and slows down the creation of skin cells.

Photo-therapy is also used for other skin conditions, such as eczema. However, it’s not as simple as just going out in the sun.

A variety of different types of UV light treatments exist. If you’re interested in trying this approach, the key is to determine which one will work best for you.

To be safely treated with photo-therapy, it’s best to talk to your doctor about your options. Your doctor will make sure it’s safe for you.

Main types of Photo-therapy

If you’re ready to try phototherapy, consider which treatment will be best for you. Your doctor may recommend combining UV therapy with a prescription cream.

Narrowband ultraviolet B (NB-UVB) light therapy

Narrow-band ultraviolet B (NB-UVB) is the most common form of photo-therapy. It can be used to treat plaque or guttate psoriasis.NB-UVB lamps and light bulbs emit wavelengths of light between 311 and 313 nanometers (nm), according to recent clinical guidelines on photo-therapy.

However, NB-UVB light therapy is most effective when performed two or three times a week. An emollient such as petroleum jelly may be applied before each session. Once the skin is clear, maintenance sessions can be performed on a weekly basis.

A 2017 study showed that around 75 percent of people receiving NB-UVB treatments found it cleared their psoriasis or led to minimal symptoms. They used fewer prescription creams for their condition, too.

NB-UVB treatments may prove more effective when combined with topical treatments, such as vitamin D analogues and corticosteroids.

Broadband ultraviolet B (BB-UVB) light therapy

Broadband ultraviolet B (BB-UVB) light therapy is an older form of phototherapy than NB-UVB. The two treatments are similar. However, BB-UVB lamps and light bulbs emit wavelengths of light between 270 and 390 nm.

BB-UVB is most effective for plaque psoriasis, although it can also be used for guttate psoriasis. It can be prescribed as a monotherapy or alongside retinoid acitretin (Soriatane). In combination therapy, the skin clears up faster, and lower doses of UVB can be used.
