Frown Lines
Frown lines typically form on the face as a result of excessive facial muscle movement, something often caused by regularly performing expressions such as smiling, laughing and, as their name suggests, frowning.
They are commonly linked to forehead lines (glabellar lines), and whilst these two forms of wrinkle indeed reside in close proximity to each other, it is important to recognise that these are not the same thing. Where forehead lines refer to the horizontal indents that appear above the eyebrows, frown lines describe the creases found between the eyes and above the nose. They can deepen over time and, like so many other types of wrinkle, are largely brought about by the declining supplies of collagen and elastin that are part and parcel of the ageing process.
