The dangers of UV lamps for nails pointed out by a study

In less than 20 minutes, these UV lamps would cause major damage to our DNA and even the destruction of certain cells.

The risks associated with the use of UV lamps have been known for years. Dermatologists therefore invite tanning enthusiasts to limit or even stop using UV cabins. Indeed, several studies have demonstrated their harmful impact on our skin. However, a new type of object has become more popular: the mini-lamps to quickly dry the varnish on the nails.

Present in beauty salons, they are also available for purchase by individuals. Moreover, they are generally offered at low prices both at major retailers and online merchant sites. However, we did not know until then if these miniature UV lamps had consequences on our health.

Researchers from the University of San Diego have looked into this question. And their findings reveal that these small objects can be harmful for our cells and much more. The full study was published in the peer-reviewed journal Nature Communications.

Two controversial devices

First of all, you should know thatthere is a real difference between the lights used in tanning booths and these small devices. Indeed, the spectrum of light does not have the same intensity nor the same effects on the body. However, both objects remain harmful but at different levels.

The tanning booth emits UVA radiation known to more easily penetrate the layers of the skin. These increase the risk of skin cancer especially as their effects combine with those of natural UV. But UV lamps, on the other hand, generate a form of irradiation which attacks the cells in depth.

During their research, the scientists studied the impact of these UV lamps on the nails but also on our DNA. They discovered that these devices increased the risk of hand cancer with repeated use. However, the most worrying thing is that these products presented as safe are actually harmful from the moment they are used.

The harmful effects of UV lamps observed from the first use

On average, drying the nails under a UV lamp lasts between 10 and 20 minutes. However, this short period of time is enough to damage between 20 and 30% of the cells present in the exposed area in the light. After 3 exposures, the figure reaches 70%.

Worse still, the devices can cause DNA damage. The researchers also explain that: some DNA damage is not repaired over time and leads to mutations following each exposure with a UV nail polish dryer« .

This is the first study of its kind on the subject. And if it can raise awareness, the authors believe that it will take several more studies and nearly 10 years of data before consumers are really aware of the dangers of these devices.
