Lateral Canthal Lines (Crow’s Feet): Smile Preservation & Periorbital Guide
How our clinicians soften outer-eye radiation lines while protecting lower-eyelid lymphatic pump function and dynamic cheek elevation.
Pre-Visit & 14-Day Post-Procedure Timeline
| Recovery Stage | Clinical Milestone | What to Expect |
|---|---|---|
| Before Your Visit | Squint vs Full Cheek Smile Assessment | We map the lateral orbital rim and identify how much of your eye crinkling comes from the orbicularis oculi sphincter versus upward push from your zygomaticus cheek muscles. |
| Days 3 to 10 After | Softening of Outer-Eye Fanning Lines | Outer-eye lines begin relaxing within 3 to 5 days, making the lateral eye frame look wider, smoother, and more awake when you laugh or squint. |
| Day 14 After | Periorbital Review & Dermal Pairing | At 14 days, dynamic crinkling is smoothly reduced. For patients with thin, crepey static skin beneath the eyes, we often pair periorbital care with additive-free PRF ($550) or Healite II LED ($55). |
Squint vs Full Cheek Smile Assessment
We map the lateral orbital rim and identify how much of your eye crinkling comes from the orbicularis oculi sphincter versus upward push from your zygomaticus cheek muscles.
Softening of Outer-Eye Fanning Lines
Outer-eye lines begin relaxing within 3 to 5 days, making the lateral eye frame look wider, smoother, and more awake when you laugh or squint.
Periorbital Review & Dermal Pairing
At 14 days, dynamic crinkling is smoothly reduced. For patients with thin, crepey static skin beneath the eyes, we often pair periorbital care with additive-free PRF ($550) or Healite II LED ($55).
Anatomical Proportions Assessed
- Lateral canthal fan of the orbicularis oculi muscle
- Zygomaticus major muscle preservation for dynamic cheek movement when smiling
- Lower-eyelid lymphatic drainage and snap-test elasticity
Essential Post-Care Guidelines
- Avoid rubbing the outer corners of your eyes or wearing tight swimming goggles for 24 to 48 hours.
- Wear UV-protective sunglasses outdoors to reduce squinting and cumulative solar elastosis.
Frequently Asked Questions
Why can’t every single line underneath the lower eyelashes be treated with muscle relaxation?
The pretarsal orbicularis oculi muscle directly beneath your lower eyelashes acts as the pump that drains lymphatic fluid from under your eyes and keeps the lower lid tight against the eye. Over-relaxing directly beneath the pupil can cause puffiness; for crepey skin right under the lashes, autologous PRF ($550) is our preferred cellular option.
