Sad Face Botox (Mona Lisa Smile)
What Is Sad Face Botox?
Sad face Botox is a botulinum toxin treatment planned to balance the activity of the facial muscles that pull the corners of the mouth downwards.
This can make a person’s expression look constantly sad, tired or unhappy, even when they are in a good mood.
The treatment, also known in everyday language as the “Mona Lisa smile”, aims to help the corners of the mouth appear more balanced and slightly lifted.
Why Does a Sad Expression Develop?
Down-turned mouth corners can occur for different reasons:
- Dominance of the muscles that pull the corners of the mouth down
- Disruption of the muscle balance of the lower face
- Facial tissues shifting downwards over time
- Intensive expression habits
This can make the face look sadder than it is, even at rest.
How Does Sad Face Botox Work?
The goal of sad face Botox is to reduce, in a controlled way, the effect of the muscles that pull the corners of the mouth down.
This balancing can help:
- The corners of the mouth sit in a more balanced position
- The expression look softer and more rested
- The face look more harmonious when smiling
The treatment is planned to preserve the natural flow of expressions.
How Is Sad Face Botox Planned?
- Expressions around the mouth and lower face are assessed in detail
- The muscle groups that pull the corners of the mouth down are analysed
- The relationship with the jawline and the area around the lips is taken into account
- A personalised treatment plan is created
Where needed, it may be assessed together with upper lip or chin treatments.
Who Might It Suit?
After a medical assessment, sad face Botox may be planned for people who:
- Feel their face constantly looks sad
- Are bothered by down-turned mouth corners
- Are not considering surgery
Natural Appearance and Patient Safety
The core approach of sad face Botox is not to change facial expression but to regulate the balance of expression.
The entire assessment and treatment process is planned with facial anatomy in mind and with patient safety as the priority.
