Nasolabial folds are the skin folds that run from the corners of the nose to the corners of the mouth, often referred to as “smile lines.” These folds become more pronounced with age as the skin loses elasticity and volume. Other factors, such as genetics, sun exposure, smoking, and weight loss, can also contribute to their prominence.
There are several options for treating nasolabial folds, including injectable treatments like hyaluronic acid, laser therapy, cosmetic surgery, and skincare products with peptides and antioxidants.
