Why Do Nasolabial Folds Appear?
Disease description:
Today, I had dinner with a friend I hadn’t seen in a long time. My friend remarked that I looked somewhat older lately. While I feel my facial skin is still in good condition, my friend attributed this impression to my nasolabial folds. I’d like to know: What causes nasolabial folds?

Hello,
The most common causes of nasolabial folds in daily life include the following:
1. **Normal aging**: As people age, skin tissue gradually deteriorates, leading to facial muscle atrophy and subsequent deepening of the nasolabial folds.
2. **Habitual facial expressions**: Nasolabial folds are significantly influenced by facial expressions—particularly frequent or exaggerated ones. For instance, repeated smiling causes recurrent contraction of the facial muscles, which over time contributes to the formation and progressive deepening of nasolabial folds due to underlying facial muscle tissue indentation.
We hope the above information is helpful to you. Wishing you a happy and healthy life!
