A tired or sad appearance is not always connected to emotions. In many cases, it is the result of muscle activity in the lower face rather than mood or personality. Before treatment, the corners of the mouth may appear downturned due to hyperactive DAO muscles or natural aging, often accompanied by visible lines running from the mouth corners to the jawline (marionette lines). This constant downward mouth tension can subtly project a sad appearance even when the face is fully relaxed.
Many patients report looking more approachable and cheerful at rest due to DAO Botox treatment, reducing the appearance of Resting Bitch Face (RBF). When the downturned corners soften, facial expressions appear lighter and more open, improving first impressions in both social and professional settings. This change does not alter personality — it simply removes the unintended signals created by muscle imbalance.
Understanding the anatomy is essential when treating the lower face. The depressor anguli oris is one of the muscles responsible for pulling the corners of the mouth downward. The depressor anguli oris muscles work continuously during speech, chewing, and subtle mouth movement, which explains why this area is prone to early wrinkles and expression-related asymmetry.
DAO Botox injections are performed by targeting the depressor anguli oris muscle, which is responsible for pulling the corners of the mouth downward. This DAO muscle sits superficially and interacts closely with surrounding structures in the lower face, making anatomical precision critical.
Each face has a unique facial anatomy, and variations in facial structure influence how strongly the DAO muscle contracts. For this reason, experienced injectors never rely on a one-size-fits-all approach.
DAO Botox works by relaxing the muscle that causes a downward pull on the corners of the mouth. Botox is injected directly into the DAO muscle, where it temporarily inhibits the nerve signals responsible for muscle contraction. As a botulinum toxin type, it belongs to a class of neuromodulators that soften overactive muscles without affecting sensation.
Botulinum toxin acts selectively. By weakening the depressor anguli oris DAO, it allows the elevators of the mouth to function without opposition. This shift restores balance rather than forcing a lifted appearance.
DAO Botox work is subtle yet highly effective when injected correctly. Unlike dermal fillers, which address volume loss, this treatment targets muscle behavior. In some cases, both approaches may be used together as part of other treatments to address aging comprehensively.
The procedure for DAO Botox begins with a consultation to discuss personal data, medical history, and aesthetic goals. A detailed consultation ensures the injector understands facial structure, asymmetries, and how the muscles responsible for expression interact at rest and in motion.
During the DAO Botox treatment, a topical numbing cream is applied to minimize discomfort before the injections. Patients consistently describe the process as involving minimal discomfort, especially compared to procedures using dermal fillers.
The ideal injection depth for DAO Botox is approximately 5 millimeters, targeting the center of the marionette lines. Injection points are carefully selected to avoid diffusion into adjacent muscles. The treatment involves a few small injections into the DAO muscle and typically requires no downtime, meaning there is no significant downtime after the session. Injecting Botox in this area requires a precise understanding of facial anatomy and experience with the lower face.
Initial effects of DAO Botox typically appear within 5–7 days, with optimal results visible after 2 weeks. Patients often report a noticeable improvement in their smile and facial expressions within 3–7 days after DAO Botox. Results typically continue to refine as muscle activity stabilizes.
Most patients will see the full results of DAO Botox within two weeks of the injections. DAO Botox is effective at reducing the appearance of marionette lines and improving facial symmetry. The treatment helps restore balance to the lower face, contributing to a more defined and sculpted chin and jawline, sometimes reducing the appearance of jowls.
Additional visible improvements may include:
DAO Botox treatment may reduce chin dimpling or orange peel texture on the chin, leading to a more sculpted jawline. For patients, this translates into a more youthful appearance without altering natural expression.
DAO Botox treatment is ideal for individuals looking to improve their facial aesthetics without invasive surgery. Most patients seeking this treatment notice a persistent downturned mouth even when relaxed. Many patients also experience mild muscle spasms in the lower face that contribute to tension.
DAO Botox treatment can be especially helpful for:
However, volume loss in the lower face may require dermal fillers instead or in combination with Botox. An individualized approach ensures facial rejuvenation without overcorrection.
DAO Botox results are generally subtle, enhancing natural looks rather than producing a frozen or unnatural appearance when performed by a skilled practitioner. The goal is to achieve natural-looking results that support the harmony of the face rather than overpower it.
It is recommended to visit an experienced injector at a clinic for the best results from DAO Botox. An expert injector understands how the depressor anguli oris muscles interact with surrounding anatomy and tailors dosing accordingly.
A tailored treatment plan respects:
This level of personalized care ensures that the youthful appearance achieved with Botox looks effortless and balanced.
Botox has FDA approval and a long-standing safety profile in aesthetic medicine. As a purified botulinum toxin, it has been extensively studied and standardized in the USA. Common side effects of DAO Botox include mild redness or swelling at the injection site, which resolves quickly. These common side effects are temporary and typically do not interfere with daily activities. Results typically last between three to six months after treatment. Because DAO Botox USA works by modulating muscle activity rather than structure, maintenance is expected.
The effects of DAO Botox typically last between three to six months after treatment. To maintain the results of it, follow-up appointments are recommended approximately every four to six months. A proper follow-up ensures consistent results without overtreatment. Most clients appreciate the predictability of this schedule, as it allows subtle adjustments over time while preserving overall facial harmony.
DAO Botox cost varies depending on how many units are required, injector experience, and clinic location. In areas such as the Upper East, pricing may reflect the level of expertise and personalized care provided. Upper East clinics often emphasize precision and conservative dosing. When compared to other treatments targeting wrinkles, DAO Botox is highly effective for expression-related aging. It can also be combined with treatments for forehead lines or glabellar lines to enhance balance across the face.
DAO Botox injections don’t change who you are. It simply reduces the downward pull created by the depressor anguli oris, allowing your natural expression to settle into a more neutral, youthful smile. By restoring balance in the lower face, this treatment supports overall facial harmony, improves movement, and enhances confidence without exaggeration. For those seeking subtle refinement rather than dramatic change, DAO Botox remains one of the most refined tools in modern aesthetic medicine.
A persistent downturned mouth often reflects overactivity of the depressor anguli oris muscles, which pull the smile downward even when the face is relaxed, subtly influencing how emotions are perceived.
The exact amount is determined during a consultation, as dosing depends on muscle strength, symmetry, and how the treatment area behaves during natural expression.
With injecting Botox in the DAO region, most people begin noticing soft changes within the first week, as tension around the corners of the mouth gradually releases.
Yes, relaxing the DAO can reduce the mechanical pull that contributes to wrinkles forming near the lower part of the face, especially those connected to repetitive expression rather than volume loss.
When done properly, the goal is a youthful appearance that feels balanced and subtle, not frozen or exaggerated, allowing natural facial movement to remain intact.
A professional understands how facial muscles interact and can place product precisely where it’s needed, ensuring the correction enhances expression rather than disrupting facial balance.
