The researchers tested 17 different types of UV drying lamps from 16 salons, attempting to determine how much radiation each was emitting. 2 They discovered considerable variation in emissions from one machine to the next, depending on how many bulbs the machine used and the wattage of those bulbs. Essentially, the more wattage expended, the faster the nails dry, but the more risk to you. The researchers used a UV-measuring meter to assess the Nail Artstrength of emissions at five different locations inside each machine. They found that the strength varied from one place to another, which means that the position of your hands inside the machine actually affects your risk level. Not surprisingly, the exposure and damage were greatest in the area of the hand closest to the bulbs.
The scientists found that dangerous harm to the skin can be rendered in as few as eight sessions under the nail dryer, depending on the machine used and how long the customer sits under it. Lower radiation machines might allow for more sessions before damage results, but the scientists figure that on average, all it takes is 11 visits to the salon to incur DNA damage to the skin. In other words, one year of monthly visits would do the job, and most of us know at least one person who gets her nails done that often--year after year.
