With age, the “facial boundaries” of young people begin to stretch and blur, and gradually lose their integrity, with displacement of the fat pads, as well as laxity of the skin and soft tissues of the face, and “sagging” or downward movement of the facial muscles.In the course of a long life, our face will eventually change with time. When entering the age group of 40-80 years old, people will enter a period of slow physiological and physical and mental decline, and with age, the face will be gradually deformed, with the appearance of skin wrinkles and facial flab, slowly changing the appearance of the young.
Facial aging, changes in bones, skin and soft tissues are determined to some extent by human genetics. “Skin wear and tear in exposed environments” also contributes to facial aging. For the younger population, the cells that make up the facial tissues are very active and there are clearly defined intervals of subcutaneous tissue with intact collateral tissues to keep the skin and facial structures in proper position. Smooth, tight skin and distinctly full cheekbones give the face a well-defined contour.
With age, the “facial boundaries” of young people begin to stretch and blur, and gradually lose their integrity, with displacement of the fat pads, as well as laxity of the skin and soft tissues of the face, and “sagging” or downward movement of the facial muscles.
In rejuvenating and correcting the shape of an aging face, we realize that a young face is actually a well-supported face, with appropriate fullness and concavity, without the sagging or tissue laxity that occurs in older people. In contrast, older faces experience fat atrophy and the formation of sunken areas in the midface (e.g., around the eyes).
The facial skeleton is a biological system that undergoes cyclic remodeling. The skeleton gradually undergoes bone resorption and osteoporotic changes, the maxilla sinks inward, and the lips contract inward, which is a manifestation of aging and deformation of the face.
Changes in people’s appearance are mainly due to changes in the soft tissue and fat composition of the face.
The fat portion of the face is usually held in place by ligaments, and as people enter middle age and old age, facial fat moves downward and into a lower position. For example, cheek fat begins to sag, accumulating below the nose and above the lips (creating a deeper “nasolabial” crease) and blurring the contours of the cheek bones. The skin and fat under the chin gradually loosens and sags, and the vastus lateralis muscle of the neck stretches out to form a “band-like structure”, while the skin loosens, giving the appearance of a “turkey” neck. In addition to laxity of the facial ligaments, the skin loses its elasticity and becomes saggy.
Changes in people’s appearance are mainly due to changes in the soft tissue and fat composition of the face.
Obviously human aging is mainly reflected in the changes of the skin, the skin itself is prone to atrophy, with age, the body’s fibroblasts, mast cells, blood vessels and elastic fibers continue to decrease. This leads to wrinkles, dark spots and even tumors on the skin. Exposure to the sun’s rays can damage elastic fibers, causing them to develop irregular accumulations, a decrease in the number of collagen fibers, and disorganization of the remaining fibrous tissue. Loose skin is often found under the eyebrows, under the chin, cheeks and eyelids, and when these tissues weaken, they stretch. Facial fat also shrinks and sags due to prolonged exposure to gravity.
Facial aging is the result of a combination of multiple processes. First, aging begins with the skin, which will become more crepey and saggy, and fine lines on the face will begin to deepen, especially in the areas of facial expression – the forehead, eyebrows, corners of the eyes and near the mouth.
Changes in the epithelium, which is the main layer of skin, make the skin less elastic. This process is known as “cross-linking,” and it involves stronger or less elastic bonds between collagen and elastin molecules. The thinning of the skin extends further, causing the facial muscles to contract, especially during times of concentration or emotional arousal, and the wrinkles to become deeper over time.
