Lip lines, also more generally referred to as “lip wrinkles,” are the vertical wrinkles that occur on your lips and the surrounding skin. Lipstick can make lip lines more noticeable, sinking into the creases to accentuate the lip lines.
Lip lines, like other wrinkles, are caused by repetitive expressions that cause folds in the skin. With lips specifically, this comes from pursing the lips, as if you are drinking out of a straw. These lines are exacerbated as you age and collagen production decreases.
Another main culprit for lip lines is sun exposure. You may be adamant about applying sunscreen to your face, but have your lips received the same attention? If not, you may be seeing signs of premature aging occurring on and around your lips.
Finally, smoking can also lead to premature aging of all skin, lips included. With lips it’s a bit of a double whammy. Not only is the condition of your skin deteriorating faster, but the actual act of smoking and constantly pursing your lips can contribute to an increase in lip lines.
