Doctor of Physics and Mathematical Sciences, Professor of Moscow Institute of Physics and Technology Stepan Andreev told socialbites.ca that the radiation power of LED lamps for manicure is very high, which is very harmful for skin cells.
“LED nail lamps are made on the basis of ultraviolet LEDs, in which a semiconductor heterostructure emits light in the wavelength range from 315 to 400 nanometers (close to ultraviolet). The radiation power can be quite high (tens of watts), on the one hand necessary for the rapid hardening of the nail polish, on the other hand, it is very harmful to skin cells. After all, ultraviolet can be attributed to ionizing radiation, as it has bactericidal properties. In fact, LED lamps for nails are like a solarium that acts locally on the fingers,” explained the professor.
Andreev noted that in terms of radiation, ultraviolet lamps are still very different from ordinary sunlight.
“In sunlight, the proportion of ultraviolet radiation is relatively small compared to visible light. The maximum radiation of the sun falls on the green color and is the pseudo-radiation of a completely black body, which includes all wavelengths in general. Therefore, to make the nail polish harden under the influence of sunlight, the effect of special LED lamps it will take much more time than under it, ”Andreev explained.
Previously, scientists from the University of California at San Diego and the University of Pittsburgh in the United States had found that ultraviolet light emitted from manicure lamps can cause skin cancer by damaging the DNA of human cells.
