What are the lines on both sides of the mouth called?

    Under normal circumstances, the lines on both sides of the mouth are called nasolabial folds. A detailed explanation is as follows:

    Nasolabial folds are a common type of wrinkle on the face, extending downward from both sides of the nostrils, appearing as two arched lines. The formation of nasolabial folds has various causes, primarily skin laxity and aging due to aging, as well as long-term repetitive facial muscle movements. As people age, the skin gradually loses elasticity, and collagen and moisture continuously deplete, making it easier for facial muscles to form wrinkles during movement, thus forming nasolabial folds. Additionally, frequent不良 facial expressions can also exacerbate the formation of nasolabial folds.

    The appearance of nasolabial folds may affect facial aesthetics and make a person look older. To improve nasolabial folds, various methods can be adopted, such as massage, balanced diet, and using anti-aging skincare products. If nasolabial folds are particularly noticeable, medical aesthetic treatments can also be considered. Under the guidance of a physician, nasolabial folds can be treated with hyaluronic acid injections. Hyaluronic acid is a gel-like substance that is injected into the depressed areas of the nasolabial folds. Hyaluronic acid has strong water-absorbing properties, which can increase skin volume and lift the skin, making nasolabial folds less pronounced. The general reference price for hyaluronic acid treatment for nasolabial folds ranges from 500 to 2000 yuan per session. Improvement is usually noticeable within 1-2 weeks after the procedure, although it may be accompanied by local symptoms such as redness, swelling, and pain.

    Before undergoing any medical aesthetic procedures, it is essential to consult a professional physician and carefully evaluate the associated risks.
