The skin is an organ that covers the surface of the human body and has various functions such as protection, secretion, regulation of body temperature, and sensation. The aging of the skin and its accessory organs in form and function is the most easily perceived aging phenomenon, so the skin is often considered a mirror of human aging, and the years also leave traces on the face. The skin of children and adolescents is more tender, elastic and generally free of wrinkles. However, as we grow older, especially after middle age, the skin becomes rougher and rougher, lacking moisture and elasticity. The facial skin and deep subcutaneous tissues and bones gradually metamorphose and atrophy, sagging and loosening, and wrinkles appear. It is found that the histological changes of skin aging are vacuolar degeneration in the epidermal spine layer, lowering of dermal papillae, disappearance of reticular fibers, gradual weakening of elastic fibers or even breaking into pieces, slow renewal of collagen fibers, reduction of hyaluronic acid in the intercellular matrix, so the water content of the dermis decreases, reduction of fat in the subcutaneous tissue, and atrophy of sweat and sebaceous glands. As a result, the skin is thin and dry, with reduced elasticity, loss of luster, laxity, wrinkles, pigmentation, and uneven skin tone. Therefore, facial wrinkles are the inevitable product of human aging and skin aging. Skin aging generally begins at the age of 30, and gradually becomes obvious with age. The aging rate has obvious individual differences and is influenced by a combination of internal and external environmental factors. In most cases, the first signs of aging are sagging of the upper eyelid, the original eyelid is covered by sagging skin tissue, the eyelid becomes narrower or disappears, crow’s feet appear at the corners of the eyes, and the eyes open weakly. The lower eyelid skin and muscles are sagging, the strength of the orbital septum is weakened so that the orbital fat herniates outward, and the orbital bone structure is changed, resulting in a deeper crease at the inferior orbital rim, forming an eye bag. Deep horizontal wrinkles appear on the forehead, “Sichuan” shaped wrinkles appear between the eyebrows, the nasolabial folds on the cheeks deepen, the skin under the chin and neck sags and changes in the shape of “sheep cheeks”, etc. Wrinkles start to become obvious around the age of 40, and both cheeks start to sink after the age of 50. Skin sagging, facial wrinkles deepen or sagging, 60-70 years old wrinkles more increased, 80 years old when most people have wrinkles throughout the face. The occurrence of facial wrinkles often varies with the age, physical condition, genetic factors, living environment, psychological and emotional, nature of work, nutritional status and diseases of individuals. Usually, wrinkles occur naturally as the skin becomes looser with age, although the age factor is not absolute. Digital age and physiological age can be inconsistent. Some people have a higher digital age, but their skin and subcutaneous tissues are not atrophied, their muscle tone is good, and their internal organs are not degenerated, so their facial wrinkles will be much less compared to their peers. Some people are originally physically obese, and once they lose weight, their faces are covered with wrinkles. Some people’s whole family look young, while some people are sisters are aging earlier, indicating that aging and genetics have a great relationship. Some people work in the field for a long time, the wind and sun face easy aging. Some people experience misfortune, bad mood, all day long, sad face, facial wrinkles will soon appear. In addition, according to our clinical observation, in general, men appear wrinkles later than women, people with dark skin are slower to form wrinkles than people with white skin, and oily skin appears later than dry skin. In today’s society where youthfulness is generally demanded, people are seeking various ways to restore their youth. Some people in their 30s and 40s, especially lesbians, are beginning to fear the onset of aging and are demanding eternal youth. However, aging is after all an inevitable law of growth and development, and strengthening physical exercise and skin care can only delay its arrival or maintain one’s original beauty. The surgical method to remove or reduce these gradually obvious wrinkles on the face and neck to restore the youthful appearance is called wrinkle removal surgery. We will gradually introduce you to the issues related to wrinkle removal surgery in the future.
