Mouth-Corner Index Stretch

Sit tall at an eye-level mirror. Soften the brows and drop the shoulders. Place both index pads lightly on the mouth corners — match the cover. Keep thumbs free upward and the other fingers curled. Soften the lips slightly parted without a forced grin. Pressure about 2/10. Hold four seconds while you intend the corners to stay awake and even, not yank outward hard. Release two seconds. Complete eight holds. Never dig nails into the corners or clamp the jaw.

• Primary — Soft proprioceptive cue for the oral commissures and nearby risorius/zygomatic soft tissue under light index pads; not a deep masseter dig.
• Neighbors — Orbicularis oris stays soft; lips may part lightly like the cover without a hard pout.
• Hand cue — Indexes on the corners; thumbs free upward like the cover — not under the jaw.
• Contrast — Mouth Corner Finger Lift adds jaw thumbs; Mouth-Corner V Lift uses a V-hand smile pattern; Nasolabial Index Stretch sits on the cheek beside the folds.
• Keep quiet — TMJ clamp and shoulder hike. Calm open gaze is the standard.

Mirror at eye level. Shoulders down. Set both index pads on the mouth corners with thumbs free upward before any hold — match the cover.

Inhale as both index pads settle on the corners. Exhale during the four-second quiet hold. Keep teeth lightly apart inside — no clench.

• Eye-level mirror
• Clean hands; optional lip balm after the set
