Deep folds also referred to as laugh lines or nasolabial folds, run down from each side of the nose to the corners of the mouth. They separate the cheeks from the upper lip.
Nasolabial folds can be defined as being medium or deep, so it's important to check the description of your chosen filler to see which type of nasolabial folds it treats, for example Juvederm Ultra 3 and Princess Filler will treat medium lines, whereas Juvederm Ultra 4 or Princess Volume treat deeper folds.
Restylane Refyne and Restylane Defyne are popularly used by many medics to erase their patient's nasolabial folds. Restylane Refyne is formulated for moderate folds, whereas Refyne is designed for deeper folds.
Treating nasolabial folds can make the face look miraculously younger and tighter, with no more skin folds. Folds are the ultimate definition of aging and being aware of them is the first step in reducing them.
Sun exposure is the biggest cause of nasolabial folds, as the skin's collagen walls break down and start to sag. Avoiding UV Rays through sun protection can help you avoid seeing your face develop folds or laugh lines early on in life.
