Nasolabial folds are a popular name, but medically they are called nasolabial folds. In addition, because of its resemblance to the character “eight”, candidates also call it eight lines. Many people think that nasolabial folds appear because of aging, but in fact it is not. Nasolabial folds are inherent in everyone, but the degree of visibility varies. The formation of nasolabial folds is due to the pulling of the facial muscles on the skin. People who love to smile or have fuller apple muscles usually have deeper nasolabial folds. If the face is thin and the skin is firm, the nasolabial folds will be lighter. Although nasolabial folds are not caused by aging, they are a sign of facial aging. As we age, the facial tissues will gradually sag, and this is especially evident when the malar muscle moves down. We often say that there are three “eights” that form after aging. The first “eight” is the tear trough and Indian lines, also known as blepharocheek grooves. The second “eight” is the nasolabial folds and lines, and the third “eight” is the marionette lines. If you are a 20 year old, you already have deep nasolabial folds. Consider facial fillers to improve the hollows. If you need facial tightening, consider dermatology programs such as photorejuvenation, Fotona4D, and Thermage. These types of modalities all use light to heat the skin to achieve deeper skin tightening, and are more effective for mild aging skin laxity. For fillers, hyaluronic acid, collagen and autologous fat are more commonly used. From a personal point of view, I recommend autologous fat. On the one hand, it can reduce fat and shape, and on the other hand, it can be utilized to improve our aging state. For the more serious nasolabial folds, you can consider doing a face lift, and then supplemented with dermatology photoelectric treatment after surgery. Facial lifting can be done by wired sculpture, lifting belt, and big and small facelift, and after the operation, you can also do a composite filler for nasolabial folds for better effect. When people get older, there will be a lack of tissue capacity, a lack of tissue capacity, the apple muscle will go down, resulting in the appearance of the corner of the mouth bag, at the same time there will be eyelid cheek groove, nasolabial folds, so the general face lift at the same time, with some filler, the postoperative effect will be better.
