A leading group of dermatologists has issued a statement saying that the use of mobile phones that come with a metal case can cause rashes to appear across the user's face and the ears.
The British Association of Dermatologists (BAD) said that the combination of Nickel-based allows and sweat could cause skin allergies, especially when exposed for an extended period and could be exacerbated in a hot and moist environment.
The phones' casings, buttons, LCD frames and even their logos could contain nickel which could cause flakiness and itchiness which would then require the application of a topical steroid cream.
Mobile Phone dermatitis as it is called, could even affect hands or fingers depending on the users' predisposition and is also known to affect some guitarists due to the presence of nickel in strings on musical instruments. Up to 30 percent of the population is said to be have an allergic reaction to Nickel.
A recent report found that 10 handsets out of 22 tested from eight popular manufacturer were found to contain nickel. The likes of LG, Samsung and Nokia have launched mobile phones that have been presented as fashion or style statements, many of them with shiny bits that could contain Nickel.
And back in 2006, another team of researcher from the Medical University of Vienna reached a similar conclusion, with the most probable solution being to use a Bluetooth handset.
