Can Facial Expressions Resemble Someone Without Changing Bone Structure
“can you resemble someone or a selfie filter of yourself with expressions muscles changes without chaning bone underlying anatomy”
Summary
Facial expression is produced by the mimetic muscles that attach to the skin and superficial fascia, allowing a wide range of changes in appearance without altering the underlying bone structure. While long‑term forces can influence bone shape over growth, normal expression and filter‑like alterations rely solely on muscle activity, leaving the facial skeleton unchanged.

Unlike other muscles in the body that are separated and enveloped by fascial layers, most of these mimic muscles originate from the bone and insert into the dermis through the SMAS.1 There are 3 muscles that do not originate from the facial bones: the frontalis, risorius, and malaris muscles.6,7 ...

We refer to this as ‘sensorimotor simulation’ to highlight the fact that the perceptual process involves activity in somatosensory and motor systems largely overlapping with those that support the production of the same facial expression. Simulation sometimes, but not always (Box 2), results in facial muscle activity in the perceiver, called facial mimicry.

The mylohyoid and anterior digastric muscles also open the jaw, running from the hyoid bone to the mandible's inner aspect. ... The muscles of facial expression outnumber the mastication muscles. The mimetic muscles are considered extensions of the face's superficial musculoaponeurotic system (SMAS).

Specifically, facial mimicry means congruent facial muscular activations in response to an emotional facial expression. For example, individuals react with an activation of the Zygomaticus major (muscle which lifts the corners of the mouth, forming a smile, labeled Zygomaticus throughout this review) when they look at a happy face, or they react with an activation of the Corrugator supercilii (muscle which draws the eyebrows together, forming a frown, hereafter labeled Corrugator), when they look at a sad face.

However, it should be noted that the current study investigated covert facial mimicry, i.e. facial muscle activation that was not visible and should therefore not have a negative effect on the other person. An alternative explanation is that the corrugator is a muscle that has a high basis activation due to its involvement in cognitive activities such as mental effort28. Visually inspecting EMG data from various studies conducted by us, we have observed a general increase in corrugator site activity in response to a stimulus, independent of the content of the stimulus.

They focused on the orbital area and noted that muscles of this region must have less ligamentous fixation of the soft tissues to the bone because of their intensive movement. Therefore, it would explain why selective resorption is present in orbital rims. William and Slice20 have claimed that changes in superomedial part of the orbital rim may be related to enlargement of the frontal sinuses21.
