The deep lines or wrinkles that form at the bottom of the nose and run downwards towards the corners of the mouth, are known as nasolabial folds. Most people possess these common facial creases, albeit in varying degrees.
The main contributors of nasolabial folds include ageing, smoking and sun exposure.
The ageing process causes the decrease of collagen and elastin from the skin’s structure. Without adequate levels of these substances, the skin is less supported. As a result, a youthfully smooth and volumised appearance is compromised. A weakened skin structure, along with the natural effects of gravity pulling down on loose skin on the cheeks, causes nasolabial folds to develop.
