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.
Deep nasolabial folds can be corrected through injections of dermal filler into the surrounding area, restoring the lost volume and softening the appearance of these creases. The goal of nasolabial fold injections is to even out the skin volume, making the area look smoother and more youthful.
