DAO Muscle Treatment

For a downturned mouth & mouth frown.

As we age, the corners of the mouth can begin to turn downward — a combination of soft tissue loss, repetitive muscle activity, and volume depletion in the chin and lower face. This often shows up as a “mouth frown,” frequently paired with marionette lines running from the mouth toward the chin. The muscle responsible is the DAO (depressor anguli oris), which overactivity pulls the mouth corners down into a “frowny” look.

Treating a Downturned Mouth

DAO Muscle Treatment

The DAO muscle acts as a tether, pulling down the corners of the mouth. Relaxing it with wrinkle treatments allows the mouth corners to lift naturally, softening the downturned look — and works as a foundation for further aesthetic enhancement.

Volume Restoration

As underlying fat and structural support in the chin and marionette line area diminish with age, volumisers help restore fullness and lift — providing extra support to the mouth corners, reducing marionette lines, and improving facial symmetry.

Understanding the Aesthetic Changes

The downward pull of the DAO muscle, combined with volume loss, creates an imbalance in the lower face that can make it appear heavier or more aged — disrupting facial harmony.

By targeting the DAO muscle and addressing volume loss together, the mouth corners can be lifted, restoring symmetry and proportion — softening marionette lines and smoothing the transition from mouth to chin for a fresher appearance.
