The depressor anguli oris (DAO) muscle is responsible for the downturn of the mouth or a frown. As we age, the DAO muscle weakens and contracts, contributing to the deepening of marionette lines and the formation of jowls along the jawline. DAO muscle Botox injections are a non-surgical cosmetic treatment that can reduce the appearance of fine lines and wrinkles, particularly around the mouth and jawline. The injections work by relaxing the muscles under the skin, which smooths the skin's surface and creates a more youthful appearance. The procedure is fairly simple, but it's important to seek treatment from a qualified and experienced provider to avoid potential side effects and complications.

Botox injections relax the DAO muscle, reducing the appearance of wrinkles and fine lines
Botox injections are an effective way to relax the DAO muscle, reducing wrinkles and fine lines. The depressor anguli oris (DAO) muscle is responsible for controlling facial movements around the corners of the mouth. As we age, this muscle weakens, causing a downward turn of the mouth, resulting in a perpetual frown or "sad smile".
Botox injections can target and relax the DAO muscle, reducing its downward pull on the mouth. The procedure involves injecting botulinum toxin type A, a neurotoxin, into specific sites along the DAO muscle. This temporarily blocks the neurotransmitters in the muscle, freezing and relaxing it, which uplifts the corners of the mouth. The treatment is often complemented with soft tissue dermal fillers to add volume and enhance the results.
The effects of DAO Botox are visible and typically last for three to six months. Side effects are usually mild and may include temporary bruising or swelling at the injection site. It is important to seek treatment from a qualified and experienced provider to avoid complications and ensure optimal results. The injector must have a good understanding of facial anatomy to determine the precise injection points based on the patient's unique facial structure.
DAO Botox is a cutting-edge technique that offers a subtle, natural, and effective solution to reducing the appearance of wrinkles and fine lines, providing a more youthful and vibrant look.

Dermal fillers are an alternative to Botox, providing volume and lift to the corners of the mouth
The depressor anguli oris (DAO) muscle is responsible for the downward turn of the mouth, often referred to as a "sad smile" or "sad mouth". This muscle is attached to the corners of the mouth and the lower jaw, and its weakening with age or overuse can result in a perpetual frown or tired appearance.
Botox injections are a popular treatment option to address this issue. Botox is a neurotoxin that, when injected into the DAO muscle, will "freeze" or relax the muscle, thereby uplifting the corners of the mouth and reducing the appearance of a frown. The procedure is quick, simple, and minimally invasive, with mild and temporary side effects.
However, dermal fillers are an alternative to Botox, providing volume and lift to the corners of the mouth. Dermal fillers are injectable substances that contain ingredients like hyaluronic acid, polyalkylimide, and polylactic acid to add volume and fullness to areas that have lost it due to ageing. When used for the corners of the mouth, fillers are injected into the areas around the mouth to restore lost volume and support the corners, creating a more youthful and happy appearance. The treatment usually takes 20-30 minutes, with immediate results that can last from 6 months to 2 years.
The choice between Botox and dermal fillers for addressing the DAO muscle depends on individual needs and considerations. Botox provides a targeted and subtle approach to uplifting the corners of the mouth, while dermal fillers offer a different technique to enhance the smile and soften frown lines and wrinkles. It is important to consult with a qualified and experienced practitioner to determine the most suitable treatment option.

DAO injections are a non-surgical cosmetic treatment, offering a minimally invasive way to enhance features
The injections work by temporarily relaxing the DAO muscle, softening the appearance of a downturned mouth. This relaxation effect allows the corners of the mouth to lift, creating a more positive and youthful appearance. The treatment can also reduce the appearance of marionette lines, which are dynamic wrinkles that extend from the corners of the mouth down to the jawline.
The injection process is quick and simple, using a fine needle to inject small amounts of Botox into specific spots along the DAO muscle. The optimal injection depth is around 5mm, but this can vary depending on the patient. It is important to inject into the distal (outer) section of the muscle to avoid possible lip asymmetry. The procedure requires no anaesthesia, and any discomfort is typically mild and temporary.
DAO Botox injections generally produce visible results for three to six months, and dermal fillers can be used in conjunction to extend their durability. However, it is crucial to seek treatment from a qualified and experienced provider to ensure effective treatment and avoid potential side effects, such as lip asymmetry or a "frozen smile".
Overall, DAO injections offer a targeted and subtle approach to enhancing the features of the lower face, providing a more youthful and positive expression without the need for invasive surgical procedures.

The DAO muscle is responsible for the downturn of the mouth, and its weakening can result in a perpetual frown
The depressor anguli oris (DAO) muscle is responsible for lowering the corners of the mouth and lips, often used when expressing displeasure or repulsion. As we age, the DAO muscle weakens and deep fat is pushed towards the more superficial layers of the chin, turning down the corners of the mouth. This condition is known as "sad smile". The weakening of the DAO muscle can also be caused by overuse, resulting in a perpetual frown or a "perma-frown" when the face is at rest.
Botox injections are a viable option to relax the DAO muscle and smooth away marionette lines, providing a more uplifted appearance. The neurotoxin injected into specific sites along the DAO muscle temporarily stops its movement and softens the appearance of a downturned mouth. This allows the corners of the mouth to uplift, creating a more relaxed and rejuvenated appearance. The procedure is quick and simple, requiring no anaesthesia, and the results typically last three to six months.
Dermal fillers are another treatment option for a downturned mouth. Unlike Botox, fillers do not relax the DAO muscle movement. Instead, fillers provide volume and lift to the corners of the mouth, reducing the downward pull of the DAO muscle. Fillers can also provide a more noticeable improvement in correcting more severe marionette lines and wrinkles when the face is at rest.
To avoid complications and ensure effective treatment, it is important to seek treatment from a qualified and experienced provider who is familiar with injection sites based on each patient's facial anatomy.

The depressor anguli oris muscle, or DAO, is located in the lower face, extending from the corner of the mouth to the lower jaw
DAO muscle Botox injections are a non-surgical cosmetic treatment that can effectively address the ageing signs associated with the DAO muscle. Botox is made of a neurotoxin called botulinum toxin type A, which, when injected into the DAO muscle, will "freeze" and relax it, thereby smoothing out wrinkles and fine lines and reducing the downward pull on the corners of the mouth. This results in a more youthful and positive facial expression.
It is important to note that the DAO muscle is not a typical Botox injection site, and care is needed to reduce potential side effects and complications. The provider should inject Botox on both sides of the mouth, with a standard dose of 2 to 4 units per side. The optimal injection depth is around 5 mm, and the injection should be administered in the distal (outer) section of the muscle on each side, close to the motor endplate.
In addition to Botox, dermal fillers can also be used to treat a downturned mouth. Fillers provide volume and lift to the corners of the mouth, reducing the pull of the DAO muscle. They are particularly effective for minimising static wrinkles when the face is at rest and can produce a more noticeable improvement in correcting severe marionette lines.

Frequently asked questions
The depressor anguli oris (DAO) muscle is a triangular-shaped muscle located in the lower area of the face. It helps control facial movement around the corners of the mouth.
Injecting the DAO muscle can help to reduce the appearance of a downturned mouth, often referred to as a "sad smile". It can also help to improve facial symmetry and reduce wrinkles and fine lines around the mouth, chin, and jawline.
As with any cosmetic procedure, there may be side effects, but they are usually minimal. Common side effects of Botox injections include temporary bruising or swelling at the injection site. For dermal fillers, side effects may include swelling, redness, and, in rare cases, lumps or asymmetry, which can be corrected.
The effects of Botox injections in the DAO muscle typically last 3-4 months, while dermal fillers can last anywhere from 6 months to a year, depending on the type of filler used and individual factors such as metabolism and lifestyle.
A skilled practitioner will inject a few units of Botox or dermal filler into the DAO muscle. The amount used is carefully calculated to ensure the desired level of muscle relaxation without compromising the natural movement of the mouth.
