The effects of social media on body image

The average person spends almost 12 hours a day connected (to what?), and approximately 4 hours on social media. As a result, the way these instruments (consider a different vocabulary word) are used could can have a significant impact on body image.
Firstly, visual platforms like Instagram and Facebook are populated by images of stunning models that are look perfect in every occasions moment of their life. Despite these pictures being the results of graphic tools, such as Photoshop, that allow to the cover up of imperfections, they promote unrealistic beauty standards. Those who do not comply with them often feel insecure about their appearance.
In addition, social media enables people to continuously compare their looks and bodies to others. Only a few likes on a photo means that you are not attracting enough (do you mean not attractive enough or not attracting enough attention?) and this seems unacceptable in the modern society. This explains why a negative body image positively correlates with depression and eating disorders.
The fashion and beauty industry aggravates this critical situation by promoting the search for perfection. Advertising often shows skinny and half- naked girls that are happy and successful.
On the other hand, social media are is also used to promote positive body messages. The Dove “Love yourself” campaign is one example of instrument (consider a different vocabulary word) that has helped many women to understand that the key to happiness is accepting yourself, and not looking like a Victoria’s Secret model.
So, what can we do? An education about the correct usage of social media is essential to  so we can benefit from these technological instruments without leading to a society in which one's only concern is the physical appearance.
