Light Therapy Mechanism
Light therapy can be delivered on any affected skin areas such as the hands or scalp, or across their whole body. But proper care and protection are given to the skin areas, such as the eyes and genitals, before treatment.
The treatment doesn’t work in on-go. Several sessions are required as the effect is gradually seen in patients. The treatment requires multiple sessions where the amount of light is gradually increased per session. The light exposure is not instant and varies for a different duration depending on the skin condition severity.
The sessions give proper time to heal the skin. Usually, the sessions go from two to three months. We need to understand the fact that every person’s skin reacts to light therapy differently. Hence, how much improvement one sees in their psoriasis symptoms and how long those benefits last depends totally on their system.
