Lip corner botox is an injection of botulinum toxin into the small muscles that pull the corners of the mouth downward, allowing the corners to rest in a softer, slightly upturned position. At Yaan Clinic in Gangnam, Seoul, lip corner lift botox takes about 5 minutes and is performed by doctors who hold MERZ Key Doctor status and have carried out thousands of botox treatments.

Many people seek this treatment because others tell them they look sad, tired or annoyed when their face is relaxed. A subtle change at the mouth corners can make the whole face look friendlier without changing your smile.

What is lip corner botox?

Lip corner botox is a non-surgical treatment that relaxes the muscle responsible for pulling the mouth corners down. When that pull is reduced, the opposing muscles that lift the corners have more influence, so the mouth looks naturally more upturned at rest.

The muscle most often treated is called the depressor anguli oris (DAO), which runs from the corner of the mouth down toward the jawline. When it is strong or overactive, the corners turn down and can create a frown-like expression or "marionette" shadow. Yaan Clinic describes the treatment as relaxing the muscles that pull the mouth corners down for a naturally smiling look.

Who is a good candidate for lip corner botox?

Lip corner botox suits people whose mouth corners turn down at rest because of muscle pull, who look angry, sad or tired when they are not, or whose mouth corners are uneven. A doctor checks whether muscle or volume loss is the main cause.

Concern	Main cause	Suitable approach
Corners turn down at rest	Overactive DAO muscle	Lip corner botox
Looks angry or sad when relaxed	Muscle pull at the corners	Lip corner botox
Uneven mouth corners	One-sided muscle strength	Lip corner botox with adjusted dosing
Deep shadow or groove beside the mouth	Volume loss	Filler, sometimes combined with botox
Sagging jowls pulling corners down	Tissue laxity	Thread lifting or skin tightening

How is lip corner botox performed at Yaan Clinic?

The doctor assesses how your mouth corners move when you smile, speak and relax, marks the injection points, and injects a small dose of botulinum toxin on each side. The injection takes about 5 minutes.

1. Consultation – you describe how your mouth looks at rest and when smiling.
2. Expression analysis – the doctor watches the corners at rest and in movement, checking for asymmetry.
3. Point and dose design – small doses are planned for each side; asymmetry is corrected by adjusting each side separately.
4. Injection – a few fine-needle injections near the lower corners of the mouth, taking about 5 minutes.
5. Aftercare – you receive simple post-treatment instructions.

Will lip corner botox affect my smile?

When dosed and placed correctly, lip corner botox should not stop you from smiling. It reduces the downward pull at the corners, while the muscles that lift your smile keep working. Yaan's FAQ addresses keeping a natural smile and avoiding an unnatural look.

The muscles around the mouth are small and close together. Too high a dose, or injections placed too close to the lips, can make the mouth feel weak or the smile uneven for a while. This is why precise, conservative dosing matters. Yaan states that it uses genuine products in the correct dosage; see genuine products and safety.

When will I see results, and how long do they last?

Results from lip corner botox typically begin within several days and settle by about two weeks, with effects usually lasting a few months. Yaan Clinic does not publish a fixed duration for this treatment; your doctor will discuss your expected timeline.

Because the change is subtle, many people notice that friends comment they look happier or more relaxed rather than noticing a specific change. Maintenance treatments can be planned once the effect starts to fade.

Lip corner botox vs filler: which is better?

Botox is better when the corners are pulled down by muscle; filler is better when they droop because of lost volume or a groove beside the mouth. Yaan Clinic's FAQ discusses botox versus filler for the mouth corners, and some patients benefit from both.

	Lip corner botox	Mouth-corner filler
How it works	Relaxes the muscle pulling corners down	Supports the corners with volume
Best for	Muscle-driven downturned corners	Volume loss, grooves, marionette shadows
Treatment time	About 5 minutes at Yaan	Short; confirmed at consultation
Onset	Gradual, over days	Immediate

Can lip corner botox be combined with other treatments?

Yes. Yaan Clinic's FAQ confirms lip corner botox can be combined with lip filler. It can also be combined with gummy smile botox when both the corners and gum show are a concern.

For a broader refresh of the lower face, lip corner botox can be part of a plan with jawline botox or treatments for wrinkles and fine lines. Your doctor will design the combination at consultation.
