This is a technical name for “light therapy” in which ultraviolet (UV) rays are used to treat a range of skin conditions such as psoriasis, vitiligo, lichen planus and eczema. This therapy is suitable for both adults and children and is often recommended when other treatments have failed to work. Its main purpose is to reduce skin inflammation and other associated symptoms.
This therapy involves multiple sessions lasting from less than a minute to several minutes. But the duration of each session gradually increases throughout the course of treatment. The treatment requires you to stand in a vertical, walk-in unit containing numerous light bulbs. These bulbs emit UVA or UVB light rays. You will be asked to undress completely as your skin needs to be completely exposed to the light. Men will be asked to cover their genital area. Both men and women will be given a pair of goggles to wear to protect your eyes against the light.
You need to be committed to the treatment. It will only work if you undergo a series of sessions in order to get maximum benefits.
