What Is DAO Botox? Downturned Mouth Corners Explained

Sep 22, 2026

DAO Botox (depressor anguli oris) relaxes the small muscles that pull the mouth corners downward. When those muscles overpower the smile elevators, the resting face can look stern or sad — even when you feel fine. Quick Aesthetics Med Spa in Allen, TX offers DAO Botox as a precise lower-face treatment, not a generic “mouth Botox.”

Search interest in DAO Botox is high, and patients often discover it after noticing marionette shadows or a chronic downturn at rest. Here’s a clear Allen-local guide.

What Does the DAO Muscle Do?

The depressor anguli oris attaches near the mouth corner and pulls it down. Overactivity contributes to a downturned resting expression and can deepen marionette appearance. DAO Botox reduces that pull so corners sit more neutrally.

Who Is a Good Candidate?

Candidates often show downward corners at rest, early marionette shadowing, or want a subtle “resting nicer” refresh without adding lip volume. We examine smile dynamics so we do not weaken muscles you need for clear speech or a natural grin.

What Treatment Feels Like

DAO injections use small doses at carefully chosen points. The appointment is brief. Full effect builds over 1–2 weeks. Longevity is often similar to other neuromodulator areas — roughly 3–4 months for many patients.

DAO Botox vs. Marionette Filler

Botox addresses muscle pull. Filler addresses volume and crease depth. Some patients need one; many benefit from a staged combination. We would rather under-promise and refine than fill first and ask questions later.

Aftercare & Cautions

Avoid rubbing the corners, follow exercise guidance, and report asymmetric smile changes promptly. Rarely, nearby muscle effects can alter smile shape — another reason experience matters for lower-face Botox.

Frequently Asked Questions — DAO Botox

Is DAO Botox the same as a lip flip?

No. A lip flip targets muscles around the upper lip border. DAO targets mouth-corner depressors.

Will it fix deep marionette folds alone?

It can improve the pull component. Deep folds usually still need filler or other support.
