What is the ideal face profile?
An ideal profile is considered to be “straight”, although this doesn’t mean that these should line up in a straight line! In general, people with a small lower jaw (mandible) have convex profiles, while people with a large mandible have one that is more concave.
Are concave faces attractive?
Concave faces often are considered less attractive than convex faces [5,13,14]. The lesser midface skeletal projection intrinsic to concave faces poorly supports the soft tissues, resulting in premature lower lid and cheek descent as well as visible bags [11,17,18].
