A Detailed Guide to DAO Anti-Wrinkle Injections

Understanding the DAO Muscle

The DAO muscle, short for Depressor Anguli Oris, is a facial muscle that plays a significant role in our expressions and the overall contour of our mouth. Its Latin name essentially translates to "that which lowers the corner of the mouth," providing a clear idea of its primary function.

Located in the lower part of the face, the DAO muscle originates from the lower border of the mandible, or lower jaw bone. It then inserts into the angle, or corner, of the mouth. When this muscle contracts it pulls the corners of the mouth downwards. This action is integral to facial expressions such as frowning or showing displeasure.

Over time the repetitive use of the DAO muscle combined with the natural process of aging and gravity can result in a more permanent downward turn of the mouth. This can give the appearance of a constant sad or stern expression (sometimes referred to as a 'bitch' face), even when the individual is not deliberately making those facial expressions.

Understanding the role of the DAO muscle is crucial when considering cosmetic treatments such as anti-wrinkle injections, as the goal of these treatments is often to relax this muscle, reducing the downward pull on the corners of the mouth and softening the appearance of fine lines and wrinkles. This can help to provide a more youthful, positive, and relaxed facial expression.

Causes of DAO or Down-turned Mouth

The Depressor Anguli Oris (DAO) is a muscle located in the lower part of your face, specifically, it originates from the mandible (the lower jaw bone) and inserts at the corner of your mouth. This muscle is responsible for several expressions, including frowning, as it pulls down the corners of the mouth.

A down-turned mouth or DAO is often the result of ageing, where the effects of gravity, volume loss, and the repetitive use of the DAO muscle combine to cause a sagging or a downward turn of the mouth corners. This leads to a perennially sad or stern expression, even when the face is in a relaxed state. The primary causes are:

1. Ageing: As we age, the skin loses elasticity and volume due to the reduction in collagen and elastin production. This, combined with the constant pull of gravity, can lead to sagging skin around the mouth and an enhanced downward pull of the DAO muscle, resulting in a down-turned mouth.
2. Repetitive Facial Expressions: Just like any other muscle in our body, the DAO muscle can also get 'overworked' due to repetitive use. Consistent frowning or pursing of lips puts constant strain on this muscle, which can eventually lead to a permanent down-turning of the mouth.
3. Bone Resorption: The process of ageing also includes resorption or loss of bone in the facial skeleton, including the jawline. This loss of support further leads to a downward turn of the mouth.
4. Dental Issues: In some cases, loss of teeth or ill-fitting dentures can lead to a change in the structure and shape of the mouth, causing a downward turn.
5. Lifestyle Factors: Factors such as excessive sun exposure, smoking, and poor diet can accelerate skin ageing and contribute to the down-turning of the mouth.

Remember, a down-turned mouth is a natural part of ageing and happens to almost everyone to some degree (definitely something we all don't want to happen we can't stop nature from taking its course). Treatments like DAO anti-wrinkle injections can help manage this condition and provide a more positive and youthful facial appearance. It's important to consult with a professional to understand the best treatment options for you.

What are DAO Anti-Wrinkle Injections?

DAO (Depressor Anguli Oris) anti-wrinkle injections are a non-surgical cosmetic treatment designed to 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 in turn smooths the surface of the skin and creates a more youthful appearance. DAO injections are an increasingly popular alternative to more invasive treatments, as they provide noticeable results without the need for downtime or recovery.

Why Choose DAO Anti-Wrinkle Injections?

There are several compelling reasons why individuals opt for DAO anti-wrinkle injections. The first and most obvious is the desire to look younger. As we age, our skin naturally loses elasticity, leading to the development of fine lines and wrinkles. DAO injections can help to reduce these signs of aging, giving the skin a smoother, more youthful appearance.

Beyond aesthetic reasons these injections also help those suffering from a condition known as 'down-turned mouth', where the corners of the mouth turn downwards, giving a perpetual sad or angry appearance. By relaxing the muscles that pull down the corners of the mouth, DAO anti-wrinkle injections can provide a more relaxed and positive facial expression which also may look like you are happier and more upbeat.

What Results Can I Expect?

The results of DAO anti-wrinkle injections can be quite dramatic, but they also look natural, which is a key factor for many people. Most patients notice a significant reduction in the appearance of fine lines and wrinkles around the mouth and jawline after treatment. The corners of the mouth may also appear more 'lifted', resulting in a more positive and youthful appearance.

Like all medical treatments results vary from person to person. The effect is not permanent and will gradually wear off over time. Typically, results can last from 2 to 4 months, after which you may choose to have the treatment again. No results are ever guranteed.

Like any medical procedure, there are potential risks and side effects associated with DAO anti-wrinkle injections. However, when administered by a qualified and experienced practitioner, these injections are generally considered safe. (BUT be realistic all medical treatments carry risk, and you need to speak with your treating practitioner for your individual assessment)

Potential side effects can include temporary bruising, swelling, redness, or discomfort at the injection site. In rare cases, patients may experience more serious side effects, such as muscle weakness or difficulty swallowing. However, these side effects are uncommon and usually resolve on their own within a few days to a week.

Before opting for DAO anti-wrinkle injections, it is important to discuss your medical history, allergies, and any medications you are currently taking with your healthcare provider. This will help to ensure that you are a good candidate for the procedure and that it is safe for you to proceed.
