Besides expressing interest in beauty or fashion, this emoji is also excellent for conveying subtle emotions. It's also used to show a chic and indifferent attitude, like "So what?" or "Whatever," when a conversation is boring or uninteresting.

It originally meant self-care, but it has evolved to have a completely different meaning among teens and people in their 20s. It has become a symbol of a "cool" attitude, showing that you're unbothered by what someone says or unfazed by any controversy. Like the confident look K-pop idols show on stage, you can use it wittily to create a self-assured vibe.
