New European research has found that too much social media use, in particular posting selfies and other photos, could increase a person's level of narcissism. 

Carried out by researchers at Swansea University, UK, and Milan University, Italy, the small-scale study looked at 74 participants aged 18 to 34 to see how their personalities changed over a four-month period.
