These folds also tend to deepen with age. Some people develop wrinkles next to the nasolabial folds, which may be more visible during smiling. These sometimes called smile lines or laugh lines.

The goal of Nasolabial fold injections is to even out the skin volume, leaving you with a smoother, refreshed-looking appearance.
