Description
Downturned smile treatment / DAO relaxing, also known as DAO Botox, is a safe and effective non-surgical treatment that improves the appearance of downturned mouth corners at rest.
These corners can sometimes give the face a sad or stern look. By targeting the depressor anguli oris (DAO) muscles, the treatment gently lifts the corners of the mouth, creating a softer and more youthful expression.
At our doctor-led clinic in Farringdon, near Barbican in Central London, all procedures are carried out by Dr Khaula, a qualified medical doctor. This ensures your treatment is medical-led, safe, and tailored to your needs.
What DAO Relaxing Treats
DAO relaxing is commonly chosen to improve:
-
Downturned mouth corners – lifting them for a more positive look
-
Sad or stern appearance – softening a serious expression
-
Marionette lines – reducing lines that extend from the mouth to the chin
How the Treatment Works
The procedure involves small injections of botulinum toxin into the DAO muscles. These muscles normally pull the corners of the mouth down. By relaxing them, the natural lift of the mouth becomes more noticeable. This creates a subtle uplift and a fresher, more approachable smile.
