The Role of Lip Corners in Passport Photos: Guidelines for a Neutral Expression

The corners of the mouth where the upper and lower lips meet are called the lip corners.

Dry lips can cause cracks or fissures at the corners of the mouth, which can develop into a crust. Sometimes the skin around the mouth corners is also damaged.

Role of the Lip Corners in Expressing Emotions

The mouth corners play an important role in expressing emotions:

• Joy: When feeling joyful, the mouth corners are pulled upwards.
• Sadness: When feeling sad, the mouth corners are pulled downwards.

Rules for Lip Corners on Passport Photos

The mouth corners should not be raised (smiling) or drooping (looking sad) in the passport photo.

According to the rules, the mouth should be closed in the passport photo, as it plays an important role in having a neutral facial expression.
