2How do I find it on my body?

Close the lips gently and find the corner of the mouth.

📖 Words explained

depressor anguli oris: A triangle-shaped muscle running up from the lower jaw to the corner of the mouth. It pulls the corner down into a frown.
nasolabial groove: The groove slanting down from beside the nostril to outside the corner of the mouth, often called the smile line. It deepens when you smile.
orbicularis oris: The ring of muscle inside the lips around the mouth. It closes and purses the lips, as when whistling.
