Prettifying is a word, firstly. It’s the act of making prettier, especially in a superficial way.
Prettifying photos is also a tech trend these days, apparently. Big enough it’s helped Snapchat and other apps grow exponentially, according to Wired magazine. While it’s great to have nice photos of yourself that look better than the real life you, the problem is people don’t meet your photos in person. They meet you.
The real you.
The real you that’s less than the prettified picture of you.
And what would you expect their reaction to be?
