Light treatment for psoriasis may be the most effective way to treat the condition. Here is why you should consider this treatment.
What is Light Therapy?
Light therapy or phototherapy is a type of treatment for photo-responsive skin ailments such as vitiligo, eczema, and psoriasis. There are several types of light therapy, but the most common type for psoriasis is Ultraviolet B (UVB) light therapy.
Regular UV light from direct sunlight and tanning beds may damage the skin and cause cancer. However, in UVB light therapy a special kind of lamp is used. This lamp only emits narrowband UVB light. It is a short wavelength of UVB rays that can treat skin problems. The amount of light used varies depending on the severity of your psoriasis and how dark or light your complexion is.
Benefits of Phototherapy for Psoriasis Patients
● Improving Your Skin Condition
Psoriasis is a condition that cannot be completely cured. However, narrowband UVB light therapy has been proven to be effective to ease psoriasis.
There are three reasons why light treatment for psoriasis is effective. Firstly, it reduces skin inflammation and itchiness. Secondly, it slows down the rate of skin cell growth. Lastly, it increases vitamin D production, which is beneficial for your skin and your general health.
● Safe and Effective
Light therapy has been proven to have minimum side effects by many studies. It is found to have an effectiveness rate of 85% with consistent treatment. Not only that, but the treatment is also generally safe for any gender and age group, including children and pregnant women.
● Side Effects
Although phototherapy is generally safe, it still has side effects. It can cause your skin to become dry. So, you have to moisturize regularly, especially before your therapy sessions.
Light therapy is not recommended for people with health conditions that make them extremely sensitive to UV light, such as skin cancer. If you take photosensitizing drugs, it can also increase the risk of side effects.
● Time Consuming
While effective, light therapy does not bring immediate benefits. On average, it takes between 15 to 25 visits until you can see the results. You have to be very consistent with your therapy schedule.
If you are interested in phototherapy, consult your doctor first to check if it is safe and suitable for you. Light treatment for psoriasis is only effective if it is overseen by a competent dermatologist.
