CHANGES IN THE FACIAL MUSCLES WITH ADVANCING AGE AND THEIR INFLUENCE ON THE AESTHETIC APPEARANCE OF THE FACE
Keywords:
skin, aging, facial muscles, wrinklesAbstract
As we age, facial features gradually change, leading to certain common marks, such as fine lines and wrinkles on the forehead, around the eyes, mouth, and changes in skin texture.
Facial aging is a complex, multifactorial process involving all tissues, including skin, muscles, fat, ligaments, and bones, which are affected due to reduced adaptation of the body to environmental changes. Decreased tissue elasticity, atrophy, loss of facial fullness and progressive bone resorption can be observed. A lot of research has been conducted examining facial tissues and age-related changes in bone, fat, and skin, while the changes that occur in facial muscles are less studied. These changes are the result of two main factors - intrinsic factors occurring within the skeletal muscles themselves and extrinsic factors outside them. After the age of 30, the muscle mass and strength starts to decrease, although does not decrease equally for everyone, as well as the loss of muscle mass and strength. Facial muscles are unique in that their primary role is to move the skin and create different facial expressions. Their importance in aging is due to the lines and furrows formed in the skin during repeated muscle contractions. As muscles change with age, their impact on the aesthetic appearance of the face is not an isolated process. This process will be more visible when changes begin to occur as a result of aging in the different layers of the skin, changes in fatty tissue, connective tissue, ligaments and bones.
In this article, we will examine the changes in the in facial musculature, that are associated with the aging process, which would lead to an understanding of their importance for maintaining the aesthetic appearance of the skin and facial structure.
