Nasolabial Folds
Nasolabial Folds — the two lines that run from the sides of the nose down to the corners of the mouth, sometimes called smile lines. They are a normal part of facial anatomy that can deepen with age as skin loses collagen, volume, and elasticity.
Key points
- They are natural anatomical folds present in most faces, becoming more pronounced with age and volume loss.
- Descending cheek fat and reduced skin elasticity contribute to their deepening over time.
- Sun protection and collagen-supporting ingredients like retinoids and vitamin C may help slow their progression.
- Because they are partly structural, topical skincare tends to soften rather than eliminate deeper folds.
Frequently asked
Are nasolabial folds a sign of aging?
They exist to some degree in most faces at any age, but they typically become deeper and more noticeable as collagen, elasticity, and facial volume decrease over time.
Can skincare get rid of nasolabial folds?
Skincare can improve skin firmness and hydration to soften their appearance, but because these folds are partly structural, topical products generally cannot fully remove them.
