Vi una foto circulando on the Internet showing a dark stripe running the length of the nail plate that was supposed to be nail cancer caused by a UV nail lamp. Is this possible?
I saw the picture as well and was asked this question by nail technicians in seven countries. The dark stripe was about the width of a drinking straw. The message attached to this image incorrectly identified this stripe as “nail cancer” caused by UV nail lamps. It was posted by someone claiming to be a friend of the person with the nail stripe, but no other information was provided. The image and message were repeated widely on the Internet, even though there was no information to back up this silly and highly speculative claim. Even so, many websites pounced on this as if it were fact, when actually this is a prime example of fake news and shows how fake news can unfairly harm your business.
Desenmascarar los motivos de las denuncias infundadas sobre las lámparas de uñas
Personally, I am convinced this particular piece of “fake information” was planted by fear-based activists for the purpose of misleading the public about UV nail lamps. Yes, I’ve seen this done many times before by these fear-based activists. This was a crazy claim, with NO supporting evidence, but evidence isn’t needed if the goal is to create irrational fear.
Acabar con los mitos: Las verdaderas causas de las manchas oscuras en las uñas
Aquí están los hechos, rayas oscuras como esta son una condición relativamente común que se produce en las manos y los pies de los hombres, mujeres y niños que nunca han estado en un salón de uñas por lo que NO es causada por lámparas UV y no hay ninguna razón para creer que esto puede ocurrir.
These dark stripes are very common around the world, mostly to those with dark skin and are relatively uncommon to those with pale skin. Many things can lead to the occurrence of these dark stripes, they happen when the cells in the nail matrix begin to produce melanin. This can be a result of pregnancy, nail biting, carpal tunnel syndrome, psoriasis, viral verrugasEn casos excepcionales, esto podría indicar la existencia de un tumor. En raras ocasiones, esto podría indicar la existencia de un tumor, pero es MUCHO más probable que estos sean causados por la exposición recreativa al sol, no por las lámparas UV para uñas.
Lámparas UV para uñas: Separar la realidad de la ficción en los problemas de salud de las uñas
The nail plate has a high natural SPF that protects the nail bed and the matrix is buried under a thick layer of skin, so it’s VERY unlikely that UV nail lamps would cause such issues. These UV lamps have been repeatedly demonstrated to be safe as used. In short, there is no reason to believe this story no reason to believe this dark stripe was caused by a UV nail lamp, and there is no reason to believe the person who posted this information. Especially since she refuses to return my e-mails or communicate with anyone else who tried to contact her and follow up on these claims.
Personally, I suspect this is an entirely made-up story, which would mean those behind this nonsense were INTENTIONALLY trying to harm the business of salons everywhere. That’s becoming commonplace. Fear-based activists regularly attack the nail industry with misinformation to sow fear and they often dupe the news media into spreading their trickery. That’s why it is so important that nail professionals become more educated about the nail and nail products, so they can fight back against these tricky deceptions. Don’t be fooled, get the facts from someone who knows.
