Controversy has recently broken out over the potential carcinogenic risk associated with exposure to UV lamps for permanent nail polish. The new LED-based polymerization devices, and their potential biological effect has not been analyzed to this date.
To evaluate the emission power and its potential biological effects on the skin of 2 types of UV LED and fluorescent curing lamps under normal use conditions compared to doses of sunlight exposure.
The emission spectrum (290nm to 450nm) of curing lamps and the Sun at noon on an average summer day in mid-latitude Spain was analyzed. The effective biological irradiance potential for erythema, non-melanoma skin cancer, DNA damage, photoimmunosuppression and permanent pigmentation was also characterized.
The high-energy UVA-visible irradiance emitted by these devices was similar to the one coming from the Sun in that spectral range while the effective biological doses were lower or similar to those also coming from the Sun. The total UV and high-energy visible dose per manicure session corresponded to that obtained from 3.5min to 6min exposures to the Sun at noon in the summer days at our latitudes.
The exposure times and doses received with the common use of artificial lamp nail drying correspond to sunlight exposures of 3min to 5min in the central hours of the day. This represents a very low carcinogenic potential compared to sunlight exposure, although similar regarding immunosuppressive potential. Photoprotective measures would further minimize the risks.
最近，关于暴露于永久性指甲油 UV 灯可能致癌的风险引起了争议。新的基于 LED 的聚合设备及其潜在的生物学效应尚未进行分析。
评估两种 UV LED 和荧光固化灯在正常使用条件下的发射功率及其对皮肤的潜在生物学效应，与阳光照射剂量进行比较。
分析了固化灯和中午阳光在中纬度西班牙夏季平均一天的发射光谱（290nm 至 450nm）。还对红斑、非黑素瘤皮肤癌、DNA 损伤、光免疫抑制和永久性色素沉着的有效生物辐照度潜力进行了描述。
这些设备发出的高能量 UVA-可见光辐照度与来自太阳的辐照度相似，而有效生物剂量则较低或与来自太阳的辐照度相似。每次美甲会话的总紫外线和高能可见光剂量相当于在我们纬度的夏季中午从 3.5 分钟到 6 分钟的太阳暴露量。
普通使用人工灯干燥指甲的暴露时间和剂量与一天中中午 3 分钟到 5 分钟的阳光暴露相当。与阳光暴露相比，这代表了非常低的致癌潜力，尽管在免疫抑制潜力方面相似。防晒措施将进一步降低风险。
