Nose to Mouth Lines
Nose to mouth lines (also known as nasolabial folds or smile lines) are the deep creases that run from both sides of the nose, down to the corners of the mouth. Having these lines is very normal and everybody has them, but their severity can vary. Many factors contribute to their development, with ageing being the main cause. With depleting levels of collagen, elastin, and subcutaneous fat in the cheek area, the skin gradually loses its structural support, and therefore starts to sag downwards creating deeper creases and darker shadows, making the nasolabial folds more noticeable.
Other factors such as exposure to environmental pollutants, smoking, sun exposure causing free radical damage and rapid weight loss or weight fluctuation can make these lines deepen. Because our faces are also so expressive, facial movements such as repetitive smiling and talking, may play a part in these lines appearing deeper from a younger age.
