Mobile devices are ubiquitous these days - we use them to read, to write, while at work, at home and on the go. However, medical professionals warn that staring at small screens such as those found on a mobile phone or e-reader could cause excessive squinting, which in turn could lead to wrinkles around the eyes, known as crow's feet, according to IANS of India.

"Use of smartphones has considerably increased over the years," Navin Taneja, director of the National Skin Center, told the news source. "Owing to the small screens they have to focus a lot on it and excessive use of facial muscles causes wrinkles around the eyes."

In addition to causing crow's feet, some say that smartphones may have a negative impact on the natural glow of one's skin. One dermatologist told the news source that staring at an illuminated screen for an excessive period of time could cause skin to become "duller" in appearance.

Those who are looking for a non-surgical way to reduce frown lines or crow's feet may want to consider undergoing a skin resurfacing or injectable treatment. Laser treatments, chemical peels or receiving an injection of Botox, Juvederm or Restalyne can make a noticeable impact on one's facial appearance, according to The American Society for Aesthetic Plastic Surgery
