Downturned Mouth Corners (DAO) Treatment
Do the corners of your mouth naturally turn downward, making you appear sad, tired, or stressed even when you’re not? Downturned mouth corners, caused by muscle imbalances involving the Depressor Anguli Oris (DAO) muscles, can affect facial expression and confidence. Skinfidelity offers expert DAO treatments that lift and brighten your smile with safe, minimally invasive procedures tailored to your unique face.
What Causes Downturned Mouth Corners?
Downturned mouth corners commonly result from overactivity of the DAO muscle, which pulls the mouth’s corners downward. Aging, genetics, and loss of collagen and muscle tone also contribute, leading to a perpetually sad or scowling appearance despite your actual mood.

Good questions
How Does DAO Treatment Work?
Skinfidelity uses Botox to relax the depressor anguli oris muscles gently. By reducing the downward pull, the treated area balances the muscles that lift the mouth corners, resulting in:
- A natural lift and brightening of your smile
- Softer, more approachable facial expression
- Enhanced overall facial harmony
This minimally invasive treatment is quick, comfortable, and produces subtle but impactful results.
Who Is a Good Candidate for DAO Treatment?
DAO treatment is ideal for patients experiencing mild to moderate downturned mouth corners caused by muscle overactivity. It’s a safe, effective option for those desiring a refreshed, friendlier facial appearance without surgery.
