Gogglebox personality Scarlett Moffatt has shared a pair of selfies on Instagram to prove to young girls that the images they see online are not always what they seem.

Moffatt, who won I'm a Celebrity Get Me Out of Here in 2016, shared the selfies to highlight that the flawless skin, doe eyes, and plump lips created by Snapchat filters are impossible to achieve in real life.

One image shows the 27-year-old's face straight on without any make-up, next to another where her features are made cartoonish by an app filter.

"To all you young girls (and older ladies) out there don't believe all you see on social media. This goes to show what make up and a filter can do ☺️ love who you are and don't compare yourself to anybody else. As dr Seuss once said.... Today you are You, that is truer than true . There is no one alive who is Youer than You. #love," she wrote beneath the post.

The reality TV personality isn't the first person to use their fame to teach young girls and women to question beauty standards in the media.

Below are five other photos that prove picture-perfect selfies aren't always what they seem.

Tiffany Brien

With almost 100,000 followers on Instagram and Facebook, fitness blogger Tiffany Brien makes a business out of marketing her image. But she didn't want her fans to think that the sculpted abs in her photos are a permanent fixture.

She posted the image above of her stomach 12 hours apart - one before bed and after a hearty meal, and the other after waking up - to emphasise that our bodies change throughout the day.

Lupita Nyong'o

Earlier this year, Oscar-winning actress Lupita Nyong'o called out Grazia magazine after her natural Afro hair was edited out of a cover image. She accused the publication of promoting a "eurocentric notion" of beauty. The magazine later apologised.

Sara Puhto

Just like the emaciated figures of 90s 'heroin chic'" models and the boyish silhouettes of 20s flappers, anyone who has scrolled through Instagram will know that an hour-glass figure with a tiny waist and pert butt is the unattainable beauty standard of our time.

To hit back at this idea, fitness blogger Sara Puhto shared a photo of herself in swimwear to show that a simple positioning of the leg can transform what a person's body looks like.

Jordan Younger

Fitness blogger Jordan Younger's story is one of the most startling examples of how a sunny attitude and a big smile can hide a serious mental illness. On The Blonde Vegan Instagram profile, she used to promote her raw vegan diet and yoga regime. She seemed a picture of health.

Behind the scenes, however, she was harbouring orthorexia - an eating disorder categorised by an obsession with so-called "clean" foods.

It had caused her hair to thin, her skin to turn orange from too much beta-carotene, and her menstrual cycle to stop.

"Come spring of 2014, there was no hiding it. I was not the picture of health I claimed to be," she wrote in Refinery 29. She has since changed her Instagram name to The Balanced Blonde, and claims to be living a healthy, label-free lifestyle.

The recent photo above illustrates that while she may not look that dissimilar to the images she posted when she was sick, her physical and mental health has vastly improved.

Cameron Diaz

Actress Cameron Diaz recently hit back against the idea that Hollywood stars are wrinkle-free mannequins from the second they wake up when she launched her book Longevity.

Instead of seeking to halt or reverse ageing, she encouraged women to accept and embrace the natural process by proudly sharing an apparently undoctored image of her visibly lined face.
