Phototherapy uses ultraviolet light, the same type of light found in natural sunlight, que se ha filtrado especialmente para proporcionar solo esas longitudes de onda más útiles para la estimulación de la repigmentación. La exposición a estos rayos ultravioleta enfocados, called UVB, puede aumentar la cantidad de melanocitos en áreas de la piel afectadas por el vitiligo y evitar que se formen nuevas manchas blancas.

A session full body phototherapy may last only 5 a 10 minutes. Para las personas con vitiligo leve, cuatro sesiones por mes pueden ayudar a reducir el tamaño de los parches claros de piel existentes y pueden prevenir el desarrollo de nuevos parches. For people with moderate to severe vitiligo, dermatologists can recommend two or three sessions per week.

Research shows that there are few side effects of phototherapy, but side effects include itching or skin irritation and a reaction similar to sunburn.

Home device options

There are currently a variety of devices on the market, but many have not been rigorously tested and may not approved by the Food and Drug Administration of the United States (FDA). It has been shown that FDA approved devices are safe and effective for use at home by patients Y, as usual, requieren una receta médica. Los dispositivos aprobados por la FDA deben recomendarse sobre los dispositivos sin la aprobación de la FDA. De lo contrario, la elección del dispositivo se basa en el tamaño y la ubicación de las lesiones de vitiligo y el porcentaje de BSA afectado. Otras consideraciones importantes en la selección de dispositivos incluyen las pólizas de seguro del paciente y los gastos de bolsillo.

laser treatment

The excimer laser is a highly focused beam of UVB light. Dermatologists focus the laser directly on the illuminated areas of the skin using a wand type device. UVB light can stimulate skin repigmentation in, restoring color to white spots.

This procedure is painless and can be administered in a physician's office within half an hour. As usual, several sessions are required to achieve the desired results, and dermatologists can suggest sessions twice a week for four to six months before determining whether additional treatment is required.

You can expect to return to work or continue their daily activities after treatment with excimer.
