What is supra alar crease?

The supra alar crease is a facial feature located above the alar (wing) portion of the nostrils. It is a subtle indentation that can be seen in some individuals and is often associated with facial aesthetics and symmetry. This crease can be more pronounced in certain ethnic groups and is sometimes considered a characteristic of beauty. In surgical contexts, it may be relevant in procedures involving the nose and surrounding facial structures.
