The face without mouth emoji is a yellow, neutral face with a furrowed brow and a small frown, shown with no mouth or nose.
It is often used to convey a sense of anonymity, or to show that you are hiding your identity or trying to remain anonymous. It can also be used to express a sense of silence or inactivity, or to show that you are feeling neutral or indifferent about something.
Samsung’s design previously featured raised eyebrows and blushing cheeks.
Face Without Mouth was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
