gel manic doors and the risk of UV nail dryers

Gel manic doors have become extremely popular in the world of beauty care due to their long-lasting and shiny optics. But as with many things in life, there is often a compromise between convenience and health. Researchers at the University of California San Diego are now throwing a shadow on the safety of these coveted manicures by pointing out the potential damage of the UV nail dryers frequently used in the nail studio.

under the microscope: Damage UV nail dryers the DNA?

The relevant nail dryers use a specific spectrum of ultraviolets light (340-395 NM) to accelerate the drying and curing process of gel manic doors. Previous concerns about UV devices focused on solariums that work in a somewhat wider spectrum (280-400 Nm) and have been shown to increase the risk of cancer. The exact spectrum used for nail dryers has so far remained largely unexplored.

Ludmil Alexandrov, a professor at UC San Diego, pointed out the negligence in dealing with these devices: "If you look at how these devices are presented, they are marketed as safe, there is no reason to worry ... But according to our level of knowledge, nobody has actually examined and researched how they influence human cells on molecular and cellular levels now. "

But the latest knowledge is a wake -up call. With the help of three different cell lines, the researchers found that a 20-minute session already led to a significant cell death among these UV sets, which was between 20 and 30 percent. With an increased exposure of three consecutive sessions, the cell death increased significantly and affected between 65 and 70 percent of the exposed cells.

It was even more alarming that the damage was not limited to cell death. The surviving cells showed clear signs of mitochondrials and DNA damage that led to mutations that are similar to those that are observed in human skin cancer. Alexandrov summarized the disturbing sequence of events: the DNA is damaged, some damage remain repaired, which leads to mutations that arise every time a UV nail dryer is used. The exposure even led to mitochondrial dysfunction, which could lead to further mutations.

practical concerns: from laboratory data to personal decisions

for Maria Zhivagui, a postdoctoral to Alexandrov's laboratory and the main author of the study, the results had more than just an academic meaning. As a former supporter of Gel manic doors, Maria had integrated her into her routine and appreciated her durability and optics, especially due to the frequent wearing of gloves in the experimental laboratory. However, when research illuminated the destructive effect of radiation on cells, it was shocked.

"When I looked at the cell dye the effect of the radiation, which is given by the devices to dry the gel nail polish and that they even made cells mutate after only a 20-minute session.

The roots of the study can be traced back to an unusual inspiration: an article in a dental practice. Alexandrov read from a young participant in a beauty competition in which rare skin cancer was diagnosed on the finger. Fascinated by the rarity, Alexandrov dived into medical literature. He found sporadic but troubling reports of unusual finger cancer in people who often received gel manic doors, such as beauty racing and beauticians. This trend indicated a possible carcinogenic cause: the UV nail dryers.

In order to rigorously examine this hypothesis, Zhivagui carried out an experiment with the three cell lines. The cells were exposed to UV light both at short notice and long-term. Even under the conditions of short-term exposure, cell death, DNA damage and mutations were clearly recognizable. The increase in reactive oxygen molecules responsible for the DNA damage and mutations underlined the risks. A genomic profiling confirmed these results and showed mutations that are typically observed in melanoma patients.

Beauty has its price: The dark side of the UV spectrum

The inherent stimulus of gel manic doors lies in its durability and flawless look. But while our understanding grows, it becomes clear that this coveted beauty treatment could have a high, invisible price. When we think of UV radiation, solariums often come to mind. However, as this study revealed, nail dryers who have so far been largely ignored could move in dangerous territory.

Solarien vs. Nagel dryer: a number of concerns

solariums have long been identified as a health risk. They emit a UV light spectrum (280-400 Nm) that is considered a carcinogen. Despite the use of a UV light spectrum (340-395 NM), which extends alarming close to the harmful area of ​​solaries, nail dryers have so far been disregarded. This raises the question: have we overlooked a significant health risk?

How often is too often?

Should you actually worry about occasional gel manic doors, or is the alarm only reserved for those who are often treated? Further research is urgently required to differentiate the exact risks. But with an abundance of cosmetic alternatives, many consider it reasonable to be careful.

The authors of the study do not take a long time around the hot porridge. Based on your data and the reports on rare hand cancer in frequent gel manicure practitioners, you postulate a significant risk of cancer by UV nail dryers. They compare the risk of solariums and suspect a potential for early skin cancer. The call for large -scale epidemiological studies is clear, even if the results could take over a decade in order to completely concretize and inform the masses.

do it right for your nails: UV-safe options for a perfect result

While gel manic doors promise long-lasting gloss optics and less split, the potential risks of UV nail dryers should not be overlooked. It is important to find a balance between the attraction of a perfect manicure and the health of nails and skin.

  1. limit UV exposure: occasional gel manic doors may be a reward, but frequent exposure to nails and skin compared to UV light could be riskier than you think. Consider stretch your gel manic doors and to use regular nail polish in between. This not only reduces your UV exposure, but also give your nails a break and promote their health.

  2. shorten the curing time: did you know that not all gel paints need the same curing time? Next time, ask your manicist if it is possible to dry the paint under the UV light for a shorter time. This small adaptation can significantly reduce your UV exposure over time.

  3. Put the sunscreen: Before you put your hand in the UV nail dryer, wear a layer of broadband sunscreen on the back of the hand and your fingers. This acts as a protective barrier against
