UV Nail Polish Dryers – It’s interesting to note that many nail polish dryers now come with a UV light. These types of UV lights are used to dry your nail polish and can cause a lot of damage to your skin and cells. This article will talk about the health risks and possible ways to avoid the harmful effects of these devices.
Causes of DNA damage:
Researchers at the University of Southern California in San Diego have discovered that UV nail polish dryers can cause DNA damage. The ultraviolet light emitted from these devices can cause oxidative stress, ROS formation, mitochondrial dysfunction, and permanent mutations in human cells.
UV Light Impairs Cell Viability in Fibroblasts and Keratinocytes:
In this study, the researchers used three cell lines: mouse embryonic fibroblasts (MEF), foreskin fibroblasts, and adult human skin keratinocytes. They found that when these cells were exposed to 20 minutes of UV light, their viability was reduced. However, when the same cells were subjected to three consecutive 20-minute exposures, their cell viability decreased by 65 to 71%.
Chronic UV Exposure Elevates Single Base Substitutions in Keratinocytes:
To better understand the effects of chronic exposure to UV, the researchers used a UV curing machine. For the study, they tested three types of keratinocytes: acutely irradiated and unirradiated, and those irradiated after an exposure period of 48 hours.
Single base substitutions were significantly elevated in both the acute and chronically irradiated samples. Acute exposure increased the transversions of C>A by 2.8 fold. Chronic exposure increased single base substitutions by 4.2 fold.
Mutagenic effects in Cells:
The ultraviolet (UV) radiation of UV nail polish dryers permanently imprints somatic mutations on mammalian cells. This results in oxidative stress induction in mammalian cells, which contributes to a variety of adverse consequences. These effects include mutagenic changes to the genomes of mammalian cells.
UV Nail-Polish Dryers Cause Mutations in Mammalian Cells:
A recent study conducted at the University of Southern California (USC) San Diego examined the mutagenic effects of UV nail polish dryers. After irradiating primary mouse embryonic fibroblasts (MEFs), human foreskin fibroblasts (HFFs), and keratinocytes in a laboratory setting, researchers observed a number of mutations in these cells. They reported that the COSMIC signatures of 18 and 36 were almost 3-fold enriched in MEFs and keratinocytes exposed to UV light.
To understand the mutagenic effects of UV nail-polish dryers on mammalian cells, researchers used two distinct methods: a single exposure of MEFs and a three-day chronic exposure. Both conditions showed significant increases in the rate of single base substitutions and C> A transversions.
Possible Prevention Measures:
The UV emitted by UV nail polish dryers is associated with cell death, mutagenicity, and DNA damage. It is possible that the device can increase the risk of hand cancer.
Limited Understanding of UV Lamp Effects on Human Cells:
UV radiation from these devices causes cell death, oxidative stress induction in mammalian cells, and DNA damage. However, there has been little study of the effects of UV lamps on human cells. Therefore, the public must wait until large-scale epidemiological studies are completed to determine whether these devices pose a health risk.
UV Nail Dryers Increase Mutations in Mammalian Cells:
A recent study from the University of California, San Diego examined three cell lines. These include mouse embryonic fibroblasts, mouse foreskin fibroblasts, and human epidermal keratinocytes.
A somatic mutation analysis of the samples showed that exposure to UV emitted by the nail polish dryer increased C:G transversions. Single base substitutions, referred to as Watson-Crick DNA base-pairs, were also increased. In the chronically exposed MEFs, the number of single base substitutions was 2.5 times greater than the number in the control samples.
It is common to see UV nail polish dryers in many nail salons. However, these devices can have adverse effects on human cells. There is a growing concern about UV nail lamps’ potential to cause DNA damage and cellular mutations. This article reviews the latest studies regarding the safety of UV nail drying devices.
Studies have shown that UV light from nail drying devices can kill human cells. Specifically, it has been shown that a single 20-minute exposure can result in the death of 20-30 percent of cells. These cellular deaths are known to increase the risk of skin cancer.
UV radiation is a known carcinogen that can lead to cutaneous malignancy. Long wavelengths of ultraviolet light can also damage the DNA of a cell. The damage to the DNA can lead to a permanent change in the cell.
