UV Lamp Manicures: The Surprising Risk That Could Lead to Skin Cancer

It is well known that manicures and pedicures are very popular among both women and men for aesthetic and practical reasons. However, in a recently done study it was shown that the use of UV lamps to cure semi permanent polishes can have potentially dangerous health consequences. The UV rays from these lamps can damage the DNA of exposed cells and cause cancerous mutations.

It is well known that the UV rays used in tanning beds have a spectrum ranging from 280 nm to 400 nm and that excessive exposure to this radiation can increase the risk of skin cancer. However, a recent study showed that the UV radiation used in lamps for curing semi-permanent nail varnish has a different spectrum, ranging from 340 nm to 395 nm. The authors of this study wanted to know whether these UV rays were also carcinogenic. The results of this study were published in the prestigious journal Nature.

The study showed that exposing cells to these UV rays for 20 minutes caused between 20 and 30% cell death. In addition, three 20 minute sessions destroyed 65 to 70% of cells. Exposure to this UV radiation also caused damage to mitochondria, damage to DNA, and an increase in reactive oxygen species molecules in the cells that remained alive. These molecules are known to promote DNA mutations and thus increase the risk of cancer.

It is important to note that these results are preliminary and that further studies are needed to determine the actual impact on human health. An epidemiological study of regular users of these lamps would be needed to establish if there is an increased risk of skin cancer from the use of these lamps. It would also be important to be able to quantify at what level of exposure the risk actually occurs.

In conclusion, it is important to be cautious when using UV lamps to cure semi-permanent nail varnishes. It is recommended to limit the exposure time and to wear gloves and goggles to minimize the potential risks. It is also advisable to keep up to date with the latest research in the field to make the best decisions for your health.
