Phototherapy has proven to be one of the most versatile and effective treatment options for a variety of inflammatory and pigmentary skin diseases. However, the use of these treatment modalities in patients of color requires some special considerations. The modality chosen, the dosing of the treatment and duration of treatment are all issues to be considered for patients of color treated with ultraviolet phototherapy. In addition, there are some diseases which are more commonly seen in patients of color. These diseases may have better treatment outcomes using newer phototherapeutic options such as the long pulsed Nd:YAG laser or UVA1. As our population in the United States becomes more diverse it would behoove all dermatologists to acquaint themselves with the special circumstances of treating ethnic patients with phototherapy.
