TREATMENTS
Downturn Smile (DAO)
A downturned smile occurs when the muscles at the corners of the mouth pull downward, often creating a tired or unhappy appearance. Using precise anti-wrinkle injections targeting the Depressor Anguli Oris muscle, we relax the DAO to subtly lift the corners of your mouth, giving you a naturally uplifted, refreshed, and more youthful smile.

What Causes a Downturned Smile?
A downturned smile occurs when the corners of the mouth are pulled downward, which can create a sad or tired facial expression even when you are not feeling that way.
This is usually caused by the Depressor Anguli Oris (DAO) muscles. These muscles sit at the corners of the mouth and pull the lips downward during certain facial expressions. When the DAO muscles are strong or overactive, they can cause the corners of the mouth to rest in a downward position. (london-dental-specialists.co.uk)
Ageing, genetics, and repeated facial movements can all contribute to this effect.
How Downturned Smile Treatment Works
Downturned smile treatment uses small amounts of anti-wrinkle injections to relax the DAO muscle on each side of the mouth.
By reducing the strength of this muscle, the downward pull at the corners of the mouth is softened. This allows the natural lifting muscles of the face to work more effectively, resulting in a subtle lift of the mouth corners and a more relaxed and positive expression. (laseraway.com)
The treatment is quick and minimally invasive, usually taking only a few minutes.
Results and Longevity
Results typically start to appear within a few days after treatment, with full results visible after around 10–14 days.
The effects usually last approximately 3–4 months, depending on the individual’s muscle activity and metabolism. Regular treatments can help maintain the lifted appearance of the mouth corners. (drmarkhamilton.com)
