Nasolabial Fold Botox: How Effective Is It

Nasolabial folds, also called laugh lines, extend from the sides of the nose to the corners of the mouth. They are caused by genetics, repeated facial gestures, and loss of collagen and elastin.

Nasolabial folds deepen with age, but smoking, sun exposure, and weight fluctuations can aggravate the condition. These lines around the mouth contribute to a tired, older look.

This article explores how Botox can help reduce nasolabial folds.

Can You Use Botox on Nasolabial Folds?

Botox can help some patients with nasolabial folds. Whether you are a suitable candidate for a Botox treatment in this area depends on the muscles that are most active when you smile. 

About 35% of the population have a canine or cuspid smile. People with this type of smile have an overactive levator labii superioris alaeque nasi muscle, which lifts the upper lips to reveal more of their teeth and gums, creating deep nasolabial folds.

Botox injections in this muscle cause it to weaken and result in a smoothening of the medial nasolabial fold. The treatment also helps patients with a gummy smile because the relaxation of the muscle causes the upper lip to drop slightly and show less teeth.

Nasolabial folds are primarily caused by age-related volume loss in the midface area. That is why the best results come from combining Botox with a dermal filler for nasolabial fold to fill in the folds with soft tissue.

The Results of Using Botox on Nasolabial Folds

Nasolabial fold Botox smooths the furrows around the nose and prevents the upper lip from moving too high. The result is a more pleasing smile and smoother skin.

The results of using Botox on nasolabial folds appear after three to seven days and typically last three to six months.

Nasolabial Folds Botox Cost

At Vibrant Skin Bar, one unit of Botox costs $12.50. Patients usually need 4-10 units for nasolabial folds.


Alone or in combination with fillers, Botox for nasolabial folds can help patients reduce the appearance of prominent laugh lines.
