Marionette lines, ‘Merkel lines’ and the muscle that lowers the corners of the mouth
These informal names describe an appearance, not your mood.
Understanding the connections
Ageing and genetic predisposition change the skin, volume and support of the lower face. The muscle that lowers the corner of the mouth, also known as the DAO, can exert an additional downward pull. However, not every marionette line is primarily a muscular issue.
The horizontal crease between the chin and lower lip is anatomically different. I therefore look at the whole mobile area around the mouth, without drawing conclusions about your feelings from its shape.
