Photosensitivity reactions in black skin.

The findings and discussions in this article clearly point out the need for a better understanding not only of the general field of photobiology and photosensitivity reactions but in particular of the role of melanin as well as the genetic bases of these diseases that have not been clearly defined to date. In other words, these discussions clearly demonstrate the need for comprehensive research into the area of photosensitivity in black skin. The fact that black individuals tend to avoid tanning as well as to avoid prolonged exposure to sunlight because of the tremendous heat load that it induces, with consequent discomfort, undoubtedly has played a role in the lower incidence of photosensitivity reactions diagnosed to date. However, this has changed, and the incidence of adverse effects has been increasing in recent years since sunning became fashionable.
