Symmetric Smile Practice

How to do it

1. 1

   Start with a neutral face in front of a mirror.

2. 2

   Slowly raise both mouth corners together.

3. 3

   Focus on the lower corner to match heights.

4. 4

   Hold 10 seconds × 8 reps.

Why it works

Expressions are trained habits. Practicing a symmetric smile with mirror feedback re-teaches the brain-muscle connection, so lifting your weaker corner gradually becomes natural.

Common mistakes

• Practicing without a mirror — visual feedback is the whole point of this exercise.
• Forcing a full grin that tenses the whole face — move only the corners, slowly.
• Pushing harder with the stronger side — focus on raising the lower corner.

Signs you're doing it right

The weaker corner should tire first, and a symmetric smile should feel less awkward after each session.

Cautions

• · Rest briefly if your face cramps.
