Light Therapy procedure depends on which areas psoriasis or skin got affected, such as the hands, scalp, or across their whole body under the supervision of a healthcare professional.
The first step of the procedure required one to protect the sensitive skin areas, such as the eyes and genitals, before treatment.
The next step is to expose the treatment area to a recommended dose of phototherapy light (UVA, UVB, PUVA as recommended according to the skin and patient). The intensity and type of light will be recommended by the doctor and can be calibrated (pre-set) on the different kinds of machines that are used.
The space from the unit has to be maintained throughout the treatment, as directed by the doctor and/or according to the light therapy treatment machine instructions. Expose the affected skin to the phototherapy light, as directed. Light therapy may require multiple sessions or to gradually increase the amount of time the skin is exposed to UV light. People usually undergo three to five treatment sessions per week over the course of 2–3 months.
After the procedure is done the skin needs to be given time to heal. People see an improvement in 2–4 weeks, depending on the type of phototherapy. Each person’s skin reacts to phototherapy differently, both in how much improvement they see in their symptoms and in how long those benefits last. The average deduction time is 3–12 months.
It works thrice a week and the improvement of skin may be shown in a week or two. It contains different lighting which helps in the treatment of the skin in a manageable way.
