Regarding this issue, let’s first look at the classification of skin wrinkles. Facial aging skin wrinkles are divided into four categories: natural wrinkles, power wrinkles, gravity wrinkles and mixed wrinkles: Natural wrinkles: mostly located in the neck of infants, in a transverse arc, consistent with the physiological skin texture. Natural wrinkles are related to the accumulation of subcutaneous fat, along with ageing wrinkles gradually deepen, the skin between the lines sagging. Power wrinkles: power wrinkles are caused by long-term contraction of expression muscles. For example, long-term frontalis muscle contraction produces forehead horizontal lines, which can appear in youth; while crow’s feet is due to the contraction of orbicularis oculi muscle, also known as smile lines, some women have started to appear crow’s feet when they are 20 years old, which may be related to more laughter. Gravity wrinkles: gravity wrinkles are formed on the basis of skin and its deep soft tissue relaxation, and then due to the effect of gravity and the formation of creases and wrinkles. Gravity wrinkles are mostly distributed in the periorbital area, zygomatic arch, jaw area and neck. Upper eyelid skin laxity forms sheep’s cheeks or turkey neck. Mixed wrinkles: caused by a variety of reasons, the mechanism is more complex, such as nasolabial folds, wrinkles around the mouth. Generally speaking, wrinkle surgery for obvious forehead horizontal lines, crow’s feet, longitudinal lines in front of the ears, as well as cheeks, under the jaw sagging effect is accurate and reliable; for gravity wrinkles of the post-surgical effect is more durable; for power wrinkles and forehead lines, crow’s feet of the recent good results. For nasolabial folds, the treatment is still not ideal, while for the longitudinal lines of the upper and lower lips, there is only a slight improvement. Current wrinkle reduction techniques correct many of the tissues associated with aging changes, such as fat, muscle and other deep tissues of the face and neck, while tightening the skin, and it is generally accepted both at home and abroad that modern wrinkle reduction can last 5-10 years.
