Perioral lip wrinkles, also known as “smokers lines” and “upper lip wrinkles” are fine or deep lines that occur around the lips and mouth. These lines are a normal sign of skin aging. As the skin ages, it loses elasticity and firmness. As a result, fine lines begin to appear and the skin becomes thinner and drier. Genetic factors, sun exposure, smoking and habitual facial movements, such as pursing the lips, can all contribute to the premature appearance of lip wrinkles. Fortunately, the appearance of facial lines can be reduced with treatment and proper skin care.
