When you have fun with your friends, you take selfies (自拍). sometimes you don't look so pretty in the photos. And, of course, if you're going to post (they), you want to look your best. What can you do?
Instead of posting a photo you don't like, you can turn to photo retouching (修图) (improve) your appearance. Many apps offer you the ability to do that. Their easy-to-use tools help you smooth your skin, make your (tooth) whiter, and more. With the apps, you can make your eyes (round) and brighter and also change the shape of your face. All in all, you can make yourself look the best (easy).
After sharing the retouched photos on moments, you get lots of likes. Is that great? Maybe not. It's almost a competition. Who looks the best, takes perfect selfies and (live) up to the standard of beauty? You need to be part of that crowd so that you don't feel left out. Worse yet, if you're not part of that crowd, you may (laugh) at because of your looks. People generally retouch themselves to have larger eyes and brighter skin. Does everyone now look same?
Perhaps it's time to post the real you and only lightly retouched if necessary.
