But one Instagrammer, 27-year-old Stacey Lee from Melbourne, is trying to expose the techniques these bloggers commonly use to portray a 'highlight reel' of their own lives.
As she's studying psychology at university, Stacey is particularly concerned about the effects this false portrayal has on young women.
"One of the recurrent themes I treat in my profession is body image and its effect on self esteem," she wrote in one post. "Self esteem is defined as confidence in ones own worth. However when that worth is tied to an image, a number on a scale, the size of clothes, the smoothness of skin, the smallness of a waist, the bigness of a butt, the definition on your abs, or the gap between your thighs, your worth will never me measured correctly."
She demonstrates this by showing a 'before and after' photo where she has subtly photoshopped parts of her body.
The changes are barely noticeable - and that's what makes this such a big issue. People could easily believe that this perfected state is actually real.
She's even shown how positioning clothes a certain way or adjusting your pose can change your look entirely.
"Don't compare your outtakes, bloopers, and negatives to someone else's highlights," she writes. "Don't forget that the 'perfect' photos you see took a camera roll of attempts."
These 'before and after' shots are helpful to make more people aware that they can't always trust what they see on Insta. Well done, Stacey!
