Introduction
Crow’s feet—those fine lines that radiate from the corners of the eyes—are among the first and most common signs of facial aging. Caused by years of smiling, squinting, and sun exposure, these dynamic wrinkles can make patients appear older or tired. Fortunately, Botox® for crow’s feet remains the gold-standard, non-surgical treatment for softening these lines while preserving natural expression. In this guide, we explain how Botox works, what patients can expect from treatment, and how clinicians can deliver safe, consistent results through Empire On-Demand training programs.
What Are Crow’s Feet?
Crow’s feet (also called lateral canthal lines) form due to repetitive contraction of the orbicularis oculi muscle surrounding the eye. Over time, decreased collagen and elastin make the skin less resilient, allowing these dynamic lines to become etched into the dermis.
Contributing factors include:
- Frequent smiling or squinting
- UV exposure and photoaging
- Loss of collagen and elasticity with age
- Smoking or oxidative stress
- Genetic predisposition
Unlike static wrinkles (present at rest), crow’s feet primarily appear with expression—making them ideal candidates for neuromodulator treatment.
How Botox Works for Crow’s Feet
Botox (botulinum toxin type A) is a purified neurotoxin that temporarily blocks acetylcholine release at the neuromuscular junction. This inhibits contraction of the orbicularis oculi, relaxing the skin and reducing wrinkle appearance.
Mechanism of action:
- Injection targets the lateral fibers of the orbicularis oculi.
- Muscle relaxation begins within 3–5 days.
- Wrinkles smooth out as skin tension decreases.
- Full results develop within 10–14 days and last 3–4 months.
According to Aesthetic Surgery Journal (2023), Botox reduces the appearance of lateral canthal lines by up to 80% after a single treatment cycle, with high patient satisfaction and low complication rates.
Ideal Candidates for Botox Around the Eyes
Botox for crow’s feet is suitable for adults seeking subtle eye rejuvenation without surgery. Ideal candidates:
- Have dynamic wrinkles (lines that appear with movement)
- Desire a smoother, refreshed eye area
- Prefer non-invasive options with minimal downtime
Contraindications:
- Pregnancy or breastfeeding
- Active skin infection near the injection site
- Neuromuscular disorders (e.g., myasthenia gravis)
- Allergy to botulinum toxin ingredients
A consultation and facial assessment determine candidacy and dosage requirements.
Botox Injection Technique for Crow’s Feet
The goal is to relax the orbicularis oculi muscle while maintaining natural expression and avoiding complications such as eyelid droop.
Typical injection approach:
- 3–4 injection points per side (lateral canthus region)
- 2–4 units per point, totaling 8–16 units per side
- Injection depth: intramuscular, 1 cm lateral to orbital rim
Safety considerations:
- Avoid injecting too close to the orbital rim to prevent diffusion into the levator palpebrae superioris (eyelid droop).
- Use a fine 30–32G needle for precision.
- Gentle pressure and post-injection cold compress minimize bruising.
Empire’s Advanced Botox & Dermal Filler Training Level II course provides hands-on anatomical mapping and injection strategy for optimal results.
What to Expect After Botox for Crow’s Feet
Immediately after treatment:
- Mild redness or pinpoint swelling (resolves in 15–30 minutes).
- Temporary tenderness possible.
Within 3–5 days:
Initial softening of lines becomes noticeable.
At 10–14 days:
Full effect achieved, with smoother, relaxed skin around the eyes.
Duration:
Results typically last 3–4 months, gradually diminishing as neuromuscular transmission resumes.
Maintenance:
Most patients schedule follow-up sessions every 3–4 months to maintain consistent results.
Benefits of Botox for Crow’s Feet
- Non-surgical and quick: Procedure takes less than 10 minutes.
- Natural results: Reduces wrinkles while preserving expression.
- Prevents wrinkle progression: Regular use can delay deep wrinkle formation.
- Boosts confidence: Creates a refreshed, youthful eye appearance.
Clinical trials confirm that repeated Botox treatments improve skin elasticity and dermal smoothness over time, even after neuromodulator effects wear off (Journal of Cosmetic Dermatology, 2022).
Possible Side Effects and Management
When administered correctly, side effects are mild and temporary.
Common reactions:
- Minor bruising or redness
- Temporary swelling
- Mild headache or tightness
Rare complications:
- Eyelid droop (ptosis) if injected too close to the orbital rim
- Asymmetry or undercorrection
Prevention:
- Use precise anatomical mapping
- Maintain injection at least 1 cm from orbital rim
- Avoid patient manipulation or massage post-treatment
Aftercare Tips for Optimal Results
To ensure smooth recovery and even diffusion of the neuromodulator:
- Avoid rubbing or massaging the area for 24 hours.
- Stay upright for at least 4 hours post-injection.
- Avoid exercise, heat exposure, or alcohol for 24 hours.
- Apply a cool compress for mild swelling.
- Avoid facials or laser treatments for 5–7 days.

Combination Treatments for Enhanced Results
Combining Botox with other modalities enhances periorbital rejuvenation:
- Dermal Fillers: Restore volume to tear troughs and cheeks for structural lift.
- Biostimulators: Improve skin texture and collagen support.
- Energy-Based Treatments: RF or ultrasound tightening for synergistic eye contour firming.
Empire’s Collagen Boosting Biostimulators for Facial Contouring course explores combination therapy for comprehensive anti-aging results.
Results: Before and After Botox for Crow’s Feet
Patients typically notice visible smoothing, reduced creasing, and brighter eyes within 1–2 weeks. The skin appears naturally rejuvenated, not “frozen.” Repeated treatments every few months maintain youthfulness while preventing new line formation.
Photography under consistent lighting helps track patient progress and demonstrates subtle improvements in skin tone and wrinkle depth.
Conclusion
Botox for crow’s feet remains the most effective, minimally invasive option for rejuvenating the delicate eye area. Its proven safety profile, rapid onset, and natural-looking results make it a cornerstone of modern aesthetic practice. When performed with anatomical precision and evidence-based technique, it delivers predictable, elegant outcomes. Through Empire On-Demand’s advanced neuromodulator courses, clinicians gain the expertise to achieve artistry in every injection—combining science, safety, and subtlety.
