Downturned mouth corners can make a face look sad, tired, or serious, even when someone feels relaxed. This appearance may relate to natural facial anatomy, muscle movement, skin changes, or facial volume loss. For some people, relaxing a specific muscle may help the corners look more neutral without surgery.
Botox for downturned mouth corners targets the depressor anguli oris (DAO), a muscle that helps pull the mouth corners downward. Results depend on facial anatomy and the cause of the concern. At Pure Medical Spa, a consultation can help you explore suitable options and understand their limitations.
What Causes Downturned Mouth Corners?
Several facial muscles work together to control mouth movement. The depressor anguli oris sits below each mouth corner and contributes to downward movement. When its activity is prominent, the corners may appear lower.
Other factors can contribute:
- Natural facial structure: Some people naturally have downturned corners.
- Skin aging: Changes in elasticity and facial volume may affect the lower face.
- Marionette lines: Folds extending from the mouth corners toward the chin can influence facial appearance.
- Muscle activity: Individual muscle strength affects how the mouth looks at rest.
- Volume loss: Reduced support around the mouth may make the corners appear recessed.
Identifying the main cause is important because muscle relaxation will not correct every concern.
How Does DAO Botox Work?
Depressor anguli oris Botox uses small injections of botulinum toxin to temporarily reduce activity in the muscle that pulls the mouth corners downward. With less downward pull, the muscles that elevate the corners may have a greater influence on their position.
This approach is often called a Botox mouth corner lift or mouth corner lift treatment. The goal is a subtle improvement, not a frozen expression. Botox does not add volume or physically reposition the skin.
Botox for downturned mouth corners may be appropriate when DAO activity contributes significantly to the appearance. However, results vary, and a visible lift is not guaranteed. Treatment in this area is generally off-label because lifting downturned mouth corners is not a specifically FDA-approved cosmetic indication for BOTOX Cosmetic.
The lower face requires careful assessment because nearby muscles support smiling, speaking, and lip movement. Incorrect placement or excessive weakening can affect these functions. A qualified medical professional should explain the potential benefits and risks before treatment.
Benefits of a Botox Mouth Corner Lift
For suitable candidates, DAO Botox may offer several potential benefits:
- A more neutral expression: Reducing downward muscle pull may soften a stern or sad-looking appearance.
- Subtle improvement: The mouth corners may appear more balanced at rest.
- A nonsurgical option: Injections do not require surgical incisions.
- Personalized treatment: Planning can account for muscle strength, asymmetry, and aesthetic goals.
- Targeted lower-face treatment: Botox for mouth corners addresses muscle movement rather than adding volume.
Botox for a frown mouth may be considered when muscle activity contributes to the expression. However, treatment cannot guarantee a particular result. The aim is to preserve natural movement while addressing the concern.
Can Botox Help With Marionette Lines?
Botox for marionette lines may be considered when DAO activity contributes to downward pulling around the mouth. However, these lines may also develop because of volume loss, skin changes, and facial structure.
Dermal fillers work differently by adding volume to selected areas. They may help address certain folds or loss of support, whereas Botox targets muscle activity. Neither option is automatically better. Your clinician can assess your anatomy and discuss the most appropriate approach.
What to Expect Before and After Treatment
Before your appointment
Discuss your medical history, medications, supplements, previous injectable treatments, allergies, and any neuromuscular conditions or swallowing difficulties. Explain your goals and ask what improvement is realistic. Your clinician should assess your mouth at rest and during movement to understand your Botox facial expression patterns.
After treatment
Temporary redness, tenderness, swelling, or bruising may occur around injection sites. Follow your clinician’s aftercare instructions and avoid rubbing the treated area unless advised otherwise.
Results develop gradually rather than appearing immediately. Follow-up should depend on your response and your clinician’s advice; there is no universal schedule for everyone.
Contact your prescribing clinician if you experience persistent discomfort, unwanted weakness, or unexpected changes in your smile, speech, or eating. Seek emergency medical care for difficulty breathing or swallowing, significant speech difficulties, or generalized weakness.
Safety, Side Effects, and Treatment Suitability
Botulinum toxin is not suitable for everyone. Tell your clinician about all medications and supplements you take, breathing or swallowing problems, neuromuscular conditions, allergies, and previous reactions to botulinum toxin.
Cosmetic treatment is generally avoided during pregnancy or breastfeeding because safety has not been adequately established. The FDA prescribing information warns that toxin effects can rarely spread beyond the injection area and cause serious symptoms.
Nutrition and hydration support general health, but no particular food or supplement has been shown to reliably improve DAO Botox results. Do not change prescribed medication or start supplements to influence treatment without professional advice.

Frequently Asked Questions
Can Botox lift downturned mouth corners?
It may help when DAO muscle activity contributes to the downward position. Results depend on facial anatomy and the cause of the concern.
How does DAO Botox work for a downturned mouth?
It temporarily reduces activity in the muscle that pulls the corners down, potentially allowing the lifting muscles to have more influence.
Can Botox make my mouth look less sad at rest?
It may create a more neutral appearance when downward muscle activity is a major factor. It cannot correct every cause of a sad-looking mouth.
Is Botox or filler better for downturned mouth corners?
Botox targets muscle activity, while filler adds volume. A qualified clinician can assess which option, if either, suits your needs.
How long does Botox for mouth corners last?
Duration varies by person, product, dose, and muscle activity. Evidence specific to DAO treatment is limited, so ask your clinician what to expect and when reassessment may be appropriate.
