Nasolabial filling is used to eliminate lines that extend from the sides of the nose to the corners of a person's mouth. As people age or due to environmental effects, their facial expressions change and lines that deepen over time develop. Nasolabial filling can be used to treat these changes.

Local anesthetic creams are first used to numb the treatment area before the procedure. This ensures a painless and comfortable procedure. A filler material containing hyaluronic acid is injected into the area under the skin using fine needles, with the dosage determined based on the depth of the lines.

The line that extends from the border of the nose to the edges of the lips is called the nasolabial region. This area, which may not be noticeable in childhood or adolescence, gradually deepens and becomes more prominent over time.

Aging and the effects of gravity on the cheek area contribute to the deepening and increased prominence of the nasolabial lines.

Therefore, it is more accurate to evaluate the nasolabial region in conjunction with the cheeks and cheekbones. This deepening, which initially starts at the border of the nose, slowly progresses towards the lips. The tired appearance of the face is further intensified by these deep lines.
