The<unk> s, commonly known as "smile lines" or "laugh lines", are facial features. They are the two skin<unk> s that run from each side of the nose to the corners of the mouth. They are defined by facial structures that support the buccal fat pad. They separate the cheeks from the upper lip. The term derives from Latin nasus for "nose" and labium for "lip".<unk>  is a misnomer, however. The proper anatomical term is melolabial<unk> , meaning the<unk>  between the cheek and lip.
