In today’s beauty-loving world, facial aging has always been a problem that plagues people and has become the biggest enemy in the pursuit of youth. In order to be beautiful and young and have a pretty face, many women pay a great price, some even take the risk and lead to disfigurement. So today let’s get to know the root cause of facial aging together. Facial aging is accompanied by the aging of the human body, what characteristics will the aging of the human body show? Skeletal system: Bone tissue decreases in calcium with age, bones become brittle and prone to fracture, and trauma healing is slower than when young. The metabolism of bone cells slows down, the direction of bone growth changes, joint mobility decreases, and the spinal vertebrae become thinner due to cartilage atrophy, resulting in a shorter spine, which is one of the reasons why people become shorter in old age. Bone atrophy is a major feature of human aging, facial bone atrophy is more obvious is the root cause of facial changes. Facial plastic surgery on bone damage brought about by bone atrophy will show more serious, aging faster. The performance of the skin: older people compared with young people dermal papillae lower, so that the epidermis and dermis interface flattened, epidermis thinner, dermal mesh fibers reduced, elastic fibers gradually lose elasticity and easy to fracture, collagen fiber renewal slowed, the majority of old fibers, collagen cross-linking increased the elasticity of the collagen fiber network reduced. The skin is loose and no longer attached to the subcutaneous structure, the hyaluronic acid in the cellular matrix is reduced while the chondroitin sulfate is relatively increased, which reduces the water content of the dermis, the subcutaneous fat is reduced, the sweat glands and sebaceous glands are atrophied, and the age spots appear due to the proliferation of local melanocytes. Muscle performance: The ratio of muscle weight to body weight decreases in the elderly compared to the young. There is a tendency to increase water, sodium and chloride outside the muscle cells and to decrease potassium content inside the cells. In addition, the number of muscle fibers decreases and their diameter decreases, making the whole muscle appear atrophied. This aging change varies by function, with a tendency to prolong contraction time in different fast-contracting or mixed muscles and to shorten contraction time in slow-contracting muscles, which affects the interaction of different motor units and reduces the effectiveness of coordinated ataxia of muscle groups, which is likely a cause of muscle weakness in the elderly. Of course, age-related changes in motor units are not sufficient to explain all movement disorders in the elderly, because complex mechanisms at different levels of the nervous system have an impact on movement. Neurological changes: At the age of 90 years the human brain weight is 10-20% less than at the age of 20 years. The main cause of weight loss is the loss of nerve cells. This loss is region-specific, for example, different regions of the brain have different levels of cell loss. From birth to 10 years of age, nerve cells have proliferated to their maximum and no longer divide, and after 20 years of age cells begin to be lost. However, the whole brain has a large cell base, and partial cell death does not cause serious functional impairment. Moreover, not much is known about the mechanism of memory, so memory loss may not be due to cell loss. From the gross anatomy, the posterior meninges thicken, the gyrus shrinks, the sulci and fissures are wide and deep, and the ventricular cavity is enlarged in the elderly. On microstructure, a decrease in neuronal nerve cells is seen. Lipofuscin deposition. Functionally, the nerve conduction velocity is slowed, recent memory is more severely reduced than distant memory, and physiological sleep time is shortened; sensory functions such as warmth, touch, and vibration sensation are reduced, taste threshold is increased, and audiovisual sensitivity is reduced. There is a general decrease in the ability to respond, especially in situations that require decisions to be made through choice. According to a recent study published in the January issue of the American Journal of Plastic and Reconstructive Surgery, doctors have long believed that facial aging is caused by atrophy and loss of elasticity of soft tissues. In fact, it’s all because of changes in facial bone structure with age. In this new study, scientists conducted CT scans of the faces of 60 male and 60 female participants, and analyzed in detail the changes in the facial bones of men and women in different age groups. The patients were divided into three groups: 20-40 years old; 41-64 years old and 65 years old and above. It was found that facial skeletal changes varied by age, but it is certain that bones undergo bone thinning with age. These changes affect the connection of skin and muscle tissue to the bones, which in turn leads to an aging face. CT scans have found that the eye sockets of both men and women will become wider and longer as they age, and changes in the size and shape of the eye sockets will lead to head lines and crow’s feet; the brow bone to the tip of the nose bone will shorten, the nasal bone begins to shrink, the nose will no longer be firm, which makes it easy to look old; cheekbones protrude less; the jawbone shrinks in length and height, and a smaller jawbone will lead to a double chin and neck wrinkles. A woman’s body functions begin to age from the age of 25, and her metabolism gradually slows down. Facial bones also begin to atrophy, the metabolism of bone cells slow down, because of the aging changes of the bones and affect the aging changes of the muscles and ligaments and the aging changes of the skin, so to change the aging of the face need to start from changing the aging of the facial bones! Shijia’s art of anti-aging technology explains that facial anti-aging starts from the anti-aging of facial bones, first of all, the direction of bone growth and bone atrophy needs to be reversed, so that the facial bones return to the direction of growth before the age of 25 and growth. With the change of bone growth direction and the reversal of bone atrophy, the growth direction and texture structure of the ligaments, muscles and skin attached to the bones are also changed and reversed, which shows the overall reversal of the whole face from bones, muscles and skin, and the reversal of youth from inside to outside.
