Targeted phototherapy is also known as concentrated phototherapy or focused phototherapy or micro phototherapy. In this ultraviolet radiation is focused and delivered with specific wavelength directly on the affected area or patch of the affected skin. It involves laser or non-laser technologies. There were few disadvantages of conventional phototherapy that these treatments gave a slow delivery of light, sometimes surrounding skin was also exposed to the rays. This treatment was very difficult to perform in children. Due to this, a new and advanced technology was introduced that is called targeted phototherapy. In this different technologise are used such as excimer laser, intense pulse light system (IPL), photodynamic therapy and ultraviolet (UV) light source.
What are the indications?Targeted phototherapy is used on skin problems, a small area is targeted or the whole body surface. In this a narrowband UVB (NB-UVB) with a wave length 311–313 nanometer is used to deliver the light energy. Few skin indications where this treatment is done are:-
Any one who has above mentioned skin disorder can opt for this treatment. Any age group can get treated depending upon the needs and condition of the skin problem. As this treatment is very safe because minimal or specified wave length is targeted on the skin area.
Use sunscreen lotions as and when required.
