Over 50 per cent youngsters concerned about unflattering pics on Facebook

Four in ten worry about friends putting uncomplimentary photos of them on the site, with women concerned about it more often than men, the Daily Mail reported.

The figures were revealed by a survey for shopping site VoucherCodes.co.uk.

Its co-founder, Duncan Jennings, dubbed the trend "virtual vanity."

A fifth of Facebook users regularly exaggerate posts on their page to make their lives appear more exciting

A quarter of the 2,000 people aged between 18 and 25 who were interviewed for the survey, admitted that they felt low and unpopular when they saw friends talking about social events to which they had not been invited.
