Millennials, defined as those born between 1980s to early 2000s, now spend more than 54 hours a year taking pictures of themselves, the survey has found.
According to the survey, around 95 per cent of teenagers have taken a selfie at some point in their lives, and around half admit to practising facial expressions before snapping.
Of the 1,000 millennials surveyed, 20 per cent said they would take selfies at a funeral.
A birthday gathering was chosen by almost half of millennials as the most selfie-required occasion, followed by weddings which bagged 34 per cent of the votes, 'The Sun' reported.
Ten per cent of teens confessed to being addicted to taking selfies.
"Even a brief glance at a Facebook page, a Twitter feed or Instagram account confirms that millennials are dedicated to chronicling their lives with selfies, and they especially enjoy sharing them with their network of acquaintances," said Luster Premium White CEO Damon Brown, whose company carried out the research.
"If you don't take a selfie during your vacation or while celebrating a special day, it is almost as if it never happened," Brown said.
