Researchers at the University of California, San Diego found that regular use of machines
Scientists studied the effects of UV radiation with a lengthwaves from 340 to 395 nm on various types of cells: adult skin keratinocytes, human foreskin fibroblasts and mouse embryonic fibroblasts. Light with this wavelength is used in manicure devices to harden coating materials.
The study showed that even one 20-minutethe session leads to the death of 20% to 30% of cells in vitro (in a Petri dish). Three procedures over three days caused 65–70% cell death for all types of tissues studied. Exposure to UV light also caused damage to the mitochondria and DNA in the remaining cells and resulted in mutations characteristic of skin cancer.
Although previous studies have shownthe carcinogenic effect of UV radiation in a solarium, so far no one has studied the effects of using gel polish drying machines, scientists say. These devices work with radiation at different wavelengths (280-400 nm in a solarium), but the effects are generally the same.
The authors of the work note that, although experiments inVitro shows harmful effects on cells from regular use of nail polish dryers, more research is needed to understand how these effects manifest themselves in the body.
