Frowning is a facial expression characterized by a downward turning of the corners of the mouth and often involves furrowing the brow. This expression typically indicates feelings of sadness, disapproval, or concern. Frowning can occur in response to negative emotions or situations, serving as a non-verbal way to communicate distress or disagreement. In addition to its emotional significance, frowning can also have physical effects. Prolonged frowning may lead to the development of fine lines or wrinkles on the forehead and around the mouth. Understanding frowning can help in recognizing emotional states in others, contributing to better communication and empathy in social interactions.
