Suntan salon franchises burst upon the economic scene in the United States in 1978 and proliferated rapidly. At present it is estimated that between 1,000 and 2,000 salons are active in the country. Of the two types in use, the more common uses a fluorescent UVB source which emits primarily the highly injurious sunburn rays between 290 and 320 nm. These are the rays that not only are responsible for the acute cellular injury and erythema called "sunburn," but at least under experimental conditions are the most carcinogenic. The UVA units are found primarily in Europe. The hazards of their rays have not been clarified as yet, but they are known to be responsible for the vast majority of exogenously photosensitized reactions that occur in the skin, they do augment the acute injury produced by the UVB rays, they cause dermal blood vessel damage, and they can produce lenticular injury. In conclusion, tanning for cosmetic purposes is not innocuous.
1978年，晒黑沙龙特许经营在美国经济舞台上突然出现并迅速扩散。目前估计美国有1000到2000家活跃的晒黑沙龙。在使用的两种类型中，较常见的一种使用荧光UVB光源，该光源主要发射290至320纳米之间具有高度伤害性的晒伤射线。这些射线不仅是导致称为“晒伤”的急性细胞损伤和红斑的原因，而且至少在实验条件下是最具致癌性的。UVA设备主要在欧洲发现。其射线的危害尚未明确，但已知它们是皮肤中发生的绝大多数外源性光敏反应的原因，它们确实会加剧UVB射线产生的急性损伤，会导致真皮血管损伤，还会造成晶状体损伤。总之，出于美容目的进行晒黑并非无害。
