Nasolabial folds are the creases that run from the edges of the nose to the sides of the mouth and Marionette lines appear from the corner of the mouth down to the chin. ​ The lines deepen and become more obvious due to a variety of reasons. These include the natural ageing process with loss of natural collagen, hyaluronic acid and elastin but also due to use over time from simple things such as talking and smiling along with sun exposure and smoking. ​ Dermal Filler can be used to plump up and fill out the lines and folds that have been created in these areas of the face.
