Coloring “gel nails”, baking with UV light, is it true that it causes skin cancer?

paint “Gel Nails” The beauty trend of all you girls that combine between nail polish color and soft gel (Soak off Gel) used in nail coating. and must use a nail dryer to dry the gel polish Lasts about 1 month on average, can’t be washed off with general nail polish remover. But more information was shared. Gel nail polish, UV light, causing cancer

After being suspicious of this issue for a long time, recently there is a research that has come out to provide clearer evidence. that the use of the machinecuring uv lightFor the gel polish on the nails. Can be dangerous, indicating that UV (or ultraviolet) light will cause cell death. and cause mutations that lead to diseaseskin cancercan

by “Ajarn Jet” Dr. Jetsada Denduangboribhand Lecturer, Department of Biology Faculty of Science Chulalongkorn University raised the research results of Maria Zhivagui and colleagues from the University of California, San Diego (University of California, San Diego), USA. Got an idea to study this. While she was studying for a Ph.D. and coincided with her penchant for coloring “Gel Nails” It’s been 2-3 years since it lasts longer.nail polishBut when she finished her research and found that just 20 minutes of UV light exposure can cause cell death and mutation, she said she was so shocked that she stopped doing gel nail polish anymore.

Professor Ludmil Alexandrov, who oversaw the research, said it was the first serious study. about the effect of the UV nail dryer on human cells, and said he decided to conduct this research. After seeing the news, there was a teenage beauty pageant who was diagnosed with the cancerKind of rare, on your fingers Therefore, according to the study of the previous research who reported cases of people doing gel nail polish very often, such as those at beauty pageants and people who love beauty Then it was a rare type of skin cancer on the fingers, indicating that there was a relationship between nail polish and this cancer. But no one has ever done deep research at the cellular DNA level before.

Their research has been published in the journal Nature Communications The famous issue dated January 17, 2023 indicates the use of a gel nail dryer. To use UV light projected in the wavelength range of 340-395 nm, it can destroy human cells.

In this research They used three types of cultured cells: keratinocytes; (keratinocyte Fibroblasts are the main cells found in the outermost layer of the epidermis. Fibroblasts are cells in the skin. which produces collagen and elastin proteins) of humans and fibroblasts from mouse embryos.

by placing those cells in a petri dish and use a nail dryer Shine a UV light on it Both acute (acute irradiation of 9 Joules per centimeter2, J/cm2 for 20 min, twice in a day) and chronic (chronic, three times for three consecutive days) compared to the unirradiated set.

Research findings on gel manicure cause cancer

The results found that one UV light exposure with a nail dryer for 20 minutes. Causes cell death by 20-30% and if irradiated 3 times in a row, 65-70% of cells die. In addition, UV light has also been found to damage mitochondria. (a constituent within the cell) and the surviving cell DNA It was mutated in the same way as that found in human cancer cells.

The research team therefore concluded that The results of this study provide strong evidence that UV curing with a nail dryer May cause cancer on the hand. This is similar to the problem with the use of tanning beds that has been found to increase the risk of skin cancer. But the research team also noted that Much more study is still needed. especially in epidemiology to confirm the risk of beingskin canceron the hands of people who regularly shine nails like this It may take decades to complete the study.

Teacher Jet indicates that in general The UV light for curing the nail color is emits light at a lower power And the time was much shorter than the aforementioned experiment. If you don’t do nails with this machine often, you shouldn’t have to worry too much.

As for if there are still concerns on the page of Cancer Council Australia recommends using a broad spectrum sunscreen SPF 30 or higher on the hands 20 minutes before exposure. or use open-fingered gloves which the nail salon should provide services to customers

It is also recommended that the risk of melanoma is highest. It’s still from overexposure to the sun’s UV rays. Therefore, they should protect themselves from the sun. The best ways to avoid UV rays (especially on days when UV levels reach level 3) are: wear clothing that covers your skin, apply sunscreen of SPF 30 or higher, wear a wide-brimmed hat, go indoors, and wear sunglasses.
