These are the small superficial vertical lines above your upper lip and sometimes below your lower lip too. They are often called smokers lines, but they usually occur in non-smokers. They are often combined with a decrease in lip volume, and patients complain their lipstick ‘bleeds’ out of the lips.
Why does it happen?
These vertical lines appear as a result of ageing, loss of collagen and UV damage. There is also a degree of overactivity of the circular muscle around the lips called the obicularis oris. Lighter skin types have less inbuilt protection from UV damage in the form of melanin so are more prone to getting wrinkles at an earlier age.
