It is said that children who love to smile have good luck, even if they are not smiling, there is an upturned lips, but also make people feel you, smiling and friendly a hundred times. But some people’s mouth corners are naturally downward, looks sad, always makes people feel as if who owes her money. The corners of the mouth down people, like a long bitter face, people do not want to get close, which makes many people distressed. Next, let’s discuss how the sagging corners of the mouth are created Cause 1: Congenital anatomical sagging This is caused by the structure of the upper lip itself, which is high in the center and low on both sides. The reasons for this are: ① Excessive development of the upper jaw ② Excessive shortening of the middle part of the upper lip and ③ Weakness of the subcutaneous tissue at the corners of the lower lip Reason 2: Aging sagging The sagging of the corners of the mouth is formed with age, along with sagging of the facial skin, loss of collagen and water, and relaxation of muscle ligaments. Reason 3: Habitual sagging of expression Today, the intense pace constantly increases our mental pressure, women not only bear, a lot of work pressure, family life responsibilities. Some mentally sensitive women under all kinds of pressure, even at night when resting in a state of tension, for a long time, the two sides of the lip angle below the muscle contraction is excessive, resulting in the phenomenon of natural is the corner of the mouth pulled down. Now, there are two ways to help us lift up the corners of the mouth Method 1: Botulinum toxin injection to lift up the corners of the mouth By injecting the right amount of Botulinum toxin below the corners of the mouth, it can inhibit the secretion of nerve endings nerve conduction substances, thus blocking neuromuscular conduction, to achieve the purpose of relaxing the muscles, when the control of the drooping corners of the mouth descending corners of the mouth muscle is relaxed, the corners of the mouth will naturally show an upward trend. Advantages: less trauma, less pain, quick recovery, no risk of scarring. Disadvantages: slight effect, short duration, multiple injections are needed to maintain the effect. Method 2: Corners of the mouth lift A small triangular area of skin is removed above the corners of the mouth, and then the corners of the mouth are suspended and lifted from three levels: muscle, subcutaneous tissue and skin. At the same time, the “descending corners of the mouth muscle” located below the corners of the mouth is also severed to remove its power to pull down the corners of the mouth, and the incision scar is left at the edge of the upper lip at the corners of the mouth, and at the edge of the lower lip for a length of about 5-8 mm each. Advantages: The effect is permanent and the postoperative scars are not too obvious. Disadvantages: All activities after surgery including eating, laughing and talking will more or less pull the corners of the mouth to stimulate scar growth, and recovery will be slow. Precautions 1.
