HOW UVB LIGHT THERAPY FUNCTIONS?
As a new offshoot of narrowband UVB, Excimer light therapy is an improvement on a treatment that used to deliver laser beams at wavelengths of about 311-312nm, used for psoriasis treatment and vitiligo treatment. The Excimer laser will be delivered using a handheld device, which ensures that the healthy skin surrounding the target area of lesions will not be exposed or affected, unlike regular narrowband UVB. As a result, a higher level of radiation can also be delivered, allowing for treatment to be completed quicker in less sessions.
At about 308nm, the wavelength of the Excimer laser light therapy will help to effectively address the outlined target area during vitiligo treatment or psoriasis treatment. Furthermore, the power density can also be tweaked accordingly, giving doctor’s more room to modify the treatment depending on the patient’s condition. The procedure will also ensure that the healthy skin around the target treatment area will also be protected and not subject to any harm.
Another benefit of UVB light therapy is that it can help to normalise cellular activities that are being changed pathologically. As a result, the Excimer laser can be used to address other conditions aside from psoriasis and vitiligo, including autoimmune diseases treatment and fungal infection treatment. This demonstrates the remarkable versatility of the Excimer laser light therapy, which is why it is one of the most popular choices of treatment for patients with various skin problems.
AFTER UVB TREATMENT
Once the Excimer laser UVB light treatment is completed, you can resume your daily activities or go back to work immediately as there is no recovery period required.
Any results obtained with UVB light therapy should last for at least three months but this could be longer depending on your condition. This will be one of the topics discussed during the initial consultation session, as follow-up sessions or estimation of results will vary from person to person. You should also note that there is a possibility of some minor side effects as a result of the UVB light therapy, but your doctor will discuss this with you during consultation.
