How Does Targeted Phototherapy Work?
Targeted phototherapy uses ultraviolet (UV) light to slow the rapid growth of skin cells that causes psoriasis plaques. Unlike traditional phototherapy that treats the entire body, targeted phototherapy focuses the light only on affected areas. This allows for higher doses of UV light to be used safely, potentially leading to faster improvement. The most common type is the excimer laser, which uses a 308 nm wavelength of UVB light.
The Treatment Process
During a targeted phototherapy session, the doctor or technician will apply the UV light directly to your psoriasis plaques using a handheld device. Each session typically lasts only a few minutes. Treatment is usually given 2-3 times per week at the start. Many people begin to see improvement within a few weeks, with significant clearing often occurring within 10-12 treatments.
Advantages of Targeted Phototherapy
One of the main benefits of targeted phototherapy is its precision. By treating only affected areas, it minimizes UV exposure to healthy skin. This can reduce the risk of side effects and may allow for higher, more effective doses. Targeted phototherapy can be particularly useful for hard-to-treat areas like the scalp, or for people with just a few stubborn plaques. It's also a good option for those who can't use or don't respond well to topical treatments.
