Ulzzang is a word from Korea that means "best face." It is a kind of fashion and beauty trend where people, usually girls, try to look very pretty and adorable. To do this, they use make-up, hair styling, and clothes that make them look cute and innocent. They also take pictures of themselves and post them online to show off their looks. Some people really like ulzzang because they think it's pretty, but other people think it's not healthy to focus so much on looks, and that people should feel good about themselves no matter what they look like.
