Nasolabial wrinkles, or expression lines, run from the sides of the nose to the corners of the mouth. Over time, the body’s natural production of collagen and hyaluronic acid decreases, causing these wrinkles to become more prominent, while the skin loses firmness.

Factors contributing to the formation of nasolabial wrinkles include facial fat loss and skin relaxation due to aging, sudden weight loss, and smoking.

Treatment for these wrinkles typically involves injectable therapies or advanced medical devices that stimulate the skin’s natural renewal mechanisms, offering overall facial rejuvenation.
