Nasolabial Folds (Smile Lines)

Nasolabial folds are creases in your skin extending from both sides of your nose to the corners of your mouth. They’re also called smile lines or laugh lines. The creases can become prominent and permanent as you age, especially if you smoke or don’t protect your skin from the sun.

What are the symptoms of laugh lines?

Laugh lines appear as folds in your skin from both sides of your nose to the corners of your mouth. When you’re younger, the folds may appear only when you smile or laugh, then disappear as your face relaxes. But over time, the lines may become deep, permanent wrinkles that appear whether you’re smiling or not. They can be symmetrical or asymmetrical.
