Everyone has a line that runs from their nose to the corner of their mouth. It just so happens that these lines get deeper and more pronounced with age. This is primarily due to the redistribution of excess cheek fat that comes with age. As the years go by, facial fat is prone to slide further south, making smile lines (or ‘nasolabial folds’, to use their technical name) more defined. While these lines are hard to erase, firming ingredients designed to restore skin elasticity can prevent them from worsening over time.
