Nasolabial fold

August 15, 2026

Aging & Wrinkles

팔자주름

The line running from beside the nose towards the corner of the mouth, known medically as the nasolabial sulcus.

What the term refers to

It is a boundary line originally present on the face, but as cheek volume decreases and tissue descends, the groove comes to look deeper.

Good to know

Rather than looking at the line alone, considering the sagging and volume of the upper cheek together can help towards a natural result.
