This year's competitors have dubbed the online campaign, #ConfidentlyBeautiful and are encouraging other women from around the globe to take part.
A representative from The Miss Universe Organisation says the initiative aims to use 'its global grassroots reach to empower women to be self-confident and strive to be their personal best'.

Miss Universe 2014 winner Paulina Vega, from Colombia, kick-started the craze and invited other women to take part.
She tweeted: 'Every #MissUniverse is #ConfidentlyBeautiful. Are you? Show us your no-makeup selfies with #ConfidentlyBeautiful.'

Keen to show her support for the campaign, Miss Dominican Republic Clarissa Molina, 24, washed off her berry-hued lip tint and smoky eye make-up to proudly show off her natural complexion
