Botulinum Toxin for Crow’s Feet (Periocular Lines)

Botulinum Toxin for Crow's feet

Crow’s feet (also known as lateral canthal lines or periocular lines) are the fine lines and wrinkles that fan out from the corners of your eyes - often more noticeable when you smile, laugh, or squint. These lines form due to repetitive muscle movement in the orbicularis oculi muscles, and they tend to become deeper over time as the skin loses collagen and elasticity. Botulinum Toxin for crow's feet is often requested when patients come for Botulinum Toxin Face.

Anatomy of the eye area

The target facial muscle is the orbicularis oculi- a round “purse-like” structure that functions to close the eyelids. Only the lateral aspect of the muscle (outer side) is treated, with accurate Botulinum Toxin injection points to produce a controlled weakening of the orbicularis oculi muscle to soften the appearance of periocular lines.

How Botulinum ToxinTreats Crow’s Feet

Botulinum Toxin Injections work by temporarily relaxing the orbicularis oculi muscle, reducing the depth and visibility of periocular fine lines and wrinkles. Here's what happens:

1. Dynamic lines fade: Botulinum Toxin reduces the strength of muscle contraction, preventing the crinkling that forms with facial movement.
2. Static lines soften over time: With reduced motion, the skin gets a “break” from folding, giving it time to repair and rebuild.
3. Skin appears brighter: The outer eye area looks fresher and less fatigued, even when smiling or laughing.

Treatment Process

THere’s what to expect when treating crow’s feet with Botulinum Toxin at Bay Aesthetic Clinic:

1. Consultation & Movement Assessment

We will assess:

• How the lines on your face appear at rest and when you smile
• Whether volume loss in the cheek or under-eye is contributing to the wrinkling
• The strength of your orbicularis oculi muscles (which encircle the eyes)

2. Botulinum Toxin Injection Planning

Botulinum Toxin for crow’s feet targets the outer part of the orbicularis oculi. The number of injection points depends on the depth and extent of the periocular lines.In some cases, Botulinum Toxin may be paired with dermal filler or skin boosters under the eyes or on the cheekbone area to improve skin texture and support.

3. During the Procedure

• The skin is cleansed thoroughly.
• A very fine needle is used to inject 2–3 points per side along the outer eye area.
• Most patients describe it as quick and tolerable — similar to a mosquito bite.

The procedure typically takes less than 10 minutes.

4. Aftercare Tips

• Avoid pressing or rubbing the area for 4–6 hours
• No facials, sauna, or strenuous workouts that day
• Minor swelling or pinpoint redness typically resolves within an hour
• You can wear makeup and return to your day after treatment

5. Results 

• Early improvement may be seen in 3–5 days
• Full results in 10–14 days
• Results last 3–4 months, with some patients noticing a longer duration over time

Your eyes will still move and express emotion—but the crinkling at the sides will be softened for a more refreshed look.

How Many Units of Botulinum Toxin Are Needed for Crow’s Feet?

The number of units required depends on:

• How prominent the lines are when smiling or squinting
• Whether lines are close to the eyes or extend further toward the temples
• Gender and muscle strength (men may need slightly more)
