Botox for Crow’s Feet: How It Works and What to Expect

You smile.

Your eyes crinkle.

And suddenly you’re staring at the little lines spreading out from the corners of your eyes wondering:

“When did those get there?”

Those lines are commonly called crow’s feet.

And here’s something important before we talk about treating them:

Crow’s feet aren’t necessarily a bad thing.

They’re created partly because you smile, laugh, squint and use your face.

But if the lines have become deeper than you’d like—or you’re beginning to see them even when you aren’t smiling—Botox may be one option for softening their appearance.

BOTOX Cosmetic is FDA approved to temporarily improve the appearance of moderate to severe lateral canthal lines, the medical term for crow’s feet, in adults.

But treating the eye area isn’t simply about making every line disappear.

At Allure Infinite Beauty in Mesa, Arizona, we think a better question is:

Which lines are coming from muscle movement—and which ones are actually coming from changes in the skin?

Because those may require very different treatments.

What Causes Crow’s Feet?

The main muscle involved in crow’s feet is called the orbicularis oculi.

It surrounds the eye and helps close the eyelids.

When you smile or squint, this muscle contracts.

That repeated movement causes the skin near the outside corner of the eye to fold.

Over time, those temporary folds can become more noticeable.

But muscle movement isn’t the only thing affecting the skin around your eyes.

Crow’s feet can also become more visible because of:

• Collagen loss
• Sun exposure
• Changes in skin elasticity
• Thinning skin
• Repeated facial expression
• Normal aging

BOTOX Cosmetic works by temporarily reducing the muscle activity contributing to moderate to severe crow’s feet. It doesn’t replace collagen or reverse every other change happening in the skin.

That distinction becomes really important when deciding whether Botox is actually the treatment you need.

Dynamic Crow’s Feet vs Static Crow’s Feet

Look in a mirror with your face completely relaxed.

Now smile as big as you can.

Do the lines around your eyes only appear when you smile?

Or are some of them still visible when your face is resting?

Those are two slightly different problems.

Dynamic crow’s feet

These lines appear primarily when the muscles around your eyes contract.

Smile.

Squint.

Laugh.

The lines show up.

Relax your face and they mostly disappear.

Because muscle movement is creating much of the wrinkle, this is exactly the type of concern a neuromodulator like Botox is designed to address.

Static crow’s feet

These lines remain visible even when you aren’t smiling.

At that point, the wrinkle may involve more than muscle movement.

The skin itself may have developed:

• Collagen loss
• Creasing
• Sun damage
• Texture changes
• Reduced elasticity

Botox may still help by reducing the repetitive movement contributing to the line.

But it may not completely erase a wrinkle that’s already present in the skin.

That’s where patients sometimes misunderstand what Botox can actually do.

Does Botox Get Rid of Crow’s Feet?

Botox can temporarily improve moderate to severe crow’s feet caused by muscle activity.

But we don’t love saying it will simply “get rid of” every line around the eyes.

There’s a difference.

If your crow’s feet become dramatically deeper when you smile, neuromodulator treatment may soften that movement considerably.

If you already have fine lines, crepey skin and texture around the eyes while completely relaxed, Botox may only address one part of the problem.

That’s when the conversation may expand beyond injectables.

Sometimes we need to treat:

the muscle AND the skin.

How Much Botox Is Used for Crow’s Feet?

For FDA-approved treatment of moderate to severe lateral canthal lines, the recommended BOTOX Cosmetic dose is 24 units total—12 units per side.

That’s a useful reference point.

But don’t turn it into a DIY prescription.

Your provider still needs to evaluate:

• Your facial anatomy
• Your muscle activity
• Your natural smile
• The pattern of your crow’s feet
• Your medical history
• Previous injectable treatments
• Your treatment goals

Botox is also not interchangeable unit-for-unit with Dysport or other botulinum toxin products. BOTOX Cosmetic’s prescribing information specifically states that its units cannot be directly compared or converted to those of other botulinum toxin preparations.

For a deeper explanation of units, see:

How Much Botox Do I Need? A Guide by Treatment Area

Will Botox Around My Eyes Make My Smile Look Weird?

This is probably one of the most important questions in this article.

Because most people don’t actually want to stop smiling.

They just want the lines softened.

The muscles surrounding your eyes contribute to facial expression, which is why treatment around the eye should be performed by a qualified provider who understands the anatomy involved.

The goal should be discussed before treatment.

Tell your injector if you want:

• Significant softening
• A conservative change
• Plenty of expression remaining
• A previous treatment recreated
• Something different from what you’ve had before

Also tell them if you’ve ever felt that Botox around your eyes changed your smile in a way you didn’t like.

Previous treatment history can be extremely useful.

There isn’t one universal definition of a “natural” result.

For one patient, natural means:

“I still want some lines when I smile.”

For another:

“I want those lines softened as much as reasonably possible.”

Neither answer is wrong.

The important thing is knowing the goal before the treatment starts.

Do You Want to Remove Your Crow’s Feet—or Just Soften Them?

This may sound like semantics, but it’s actually a useful conversation.

Your smile involves movement.

And some movement around the eyes is normal.

When patients tell us:

“I don’t want any crow’s feet.”

we may ask what they actually mean.

Do you hate the wrinkles when your face is resting?

Do you dislike how deep they become when you smile?

Do they make you feel older?

Do you dislike how makeup settles into them?

Are you seeing crepey skin underneath your eyes and calling all of it crow’s feet?

Those answers help identify the actual problem.

Because someone with strong dynamic crow’s feet may need a completely different treatment strategy than someone whose primary concern is thin, sun-damaged skin around the eyes.

Why Do I Still Have Lines After My Crow’s Feet Botox?

This is common enough that it deserves its own section.

Imagine we significantly reduce the muscle movement creating your crow’s feet.

Now you smile.

The lines are much softer.

But when you relax your face, there’s still a small crease visible.

Does that mean the Botox failed?

Not necessarily.

The treatment may have successfully reduced the movement while a static line remains in the skin.

Think about folding a piece of paper repeatedly.

Eventually, even when you unfold it, you can still see where the fold was.

Skin isn’t paper, obviously, but the concept helps explain why reducing movement doesn’t always instantly remove an established crease.

This is when we may start asking whether the skin itself needs treatment.

Botox vs CO2 for Crow’s Feet

These treatments do completely different jobs.

Botox

Primarily addresses muscle activity contributing to dynamic wrinkles.

CO2 laser resurfacing

Targets the skin itself, with the goal of improving concerns such as texture, fine lines and signs of photoaging through a completely different mechanism.

For the right patient, those treatments aren’t necessarily competitors.

They may address different components of the same concern.

Someone could have:

Strong muscle movement + etched skin lines.

Botox addresses one component.

Resurfacing may address another.

That is very different from simply continuing to add more Botox because a line remains visible.

Botox vs Microneedling for Crow’s Feet

Same basic idea.

Microneedling is a collagen-focused skin treatment.

Botox is a neuromodulator.

If your concern appears mainly when you smile, muscle activity may be playing the larger role.

If you’re bothered by texture and fine lines that remain at rest, skin quality becomes more relevant.

Some patients may ultimately benefit from both approaches at different points in their treatment plan.

We’ll cover this comparison much more deeply in a separate guide:

Botox vs Microneedling for Wrinkles: Which One Do You Actually Need?

What About Crepey Skin Under My Eyes?

This is where people frequently use the term “crow’s feet” for something that isn’t really the same problem.

Crow’s feet are primarily located toward the outside corners of the eyes.

Crepey under-eye skin may involve:

• Thin skin
• Collagen loss
• Skin laxity
• Texture changes
• Sun damage
• Volume changes
• A combination of factors

Trying to solve all of those problems with Botox doesn’t make sense.

If the primary complaint is:

“The skin underneath my eyes looks thin and wrinkled all the time,”

we need to figure out what’s actually creating that appearance.

The answer may involve a completely different treatment category.

Can Botox Help Under-Eye Wrinkles?

This is where treatment becomes more individualized.

BOTOX Cosmetic’s FDA-approved indication for crow’s feet applies to moderate to severe lateral canthal lines associated with orbicularis oculi activity—the lines at the outer eye area.

Other cosmetic uses around the eye may be considered off-label.

That doesn’t automatically mean inappropriate; off-label prescribing is common in medicine.

It does mean those decisions should be made by an appropriately licensed medical provider after evaluating the patient.

We would not recommend choosing an under-eye injectable treatment based on a TikTok diagram or a generic injection map.

The eye area deserves more respect than that.

Will Crow’s Feet Botox Make My Eyes Look Bigger?

You may see claims online that Botox can “open the eyes.”

Be careful with those promises.

Neuromodulators can alter muscle activity, and subtle changes in the upper face may change how someone’s eye area appears.

But Botox isn’t surgically enlarging the eyes.

It isn’t removing eyelid skin.

And it isn’t correcting every cause of a tired-looking eye area.

If someone feels their eyes look small or tired, we first want to determine why.

Possibilities might include:

• Brow position
• Eyelid skin laxity
• Under-eye hollowing
• Skin texture
• Pigmentation
• Puffiness
• Muscle movement
• Facial anatomy

Those aren’t all Botox problems.

Can Crow’s Feet Botox Affect the Eyelids or Eyes?

Botox is a prescription medication, and treatment around the eyes does have potential risks and side effects.

In clinical trials of BOTOX Cosmetic for lateral canthal lines, eyelid edema was reported in 1% of treated subjects in the prescribing information.

The current prescribing information also notes reports of dry eye following BOTOX Cosmetic treatment in or near the orbicularis oculi muscle. Persistent symptoms such as eye irritation, light sensitivity or visual changes warrant medical attention.

There are additional warnings and risks associated with botulinum toxin products, including a boxed warning regarding possible distant spread of toxin effect.

This isn’t meant to scare you away from treatment.

It’s meant to reinforce something we believe strongly:

Botox may be common, but it’s still a medical treatment.

You deserve an appropriate medical evaluation and a provider who understands the anatomy they’re treating.

How Quickly Does Crow’s Feet Botox Work?

With BOTOX Cosmetic treatment of forehead lines, frown lines and crow’s feet, patients may begin noticing results within 1–2 days, with full results developing over time and evaluated at 30 days.

That means you should not judge your final result the morning after your appointment.

Give the medication time to work.

And follow your provider’s instructions regarding when they want you to evaluate the result.

How Long Does Botox for Crow’s Feet Last?

BOTOX Cosmetic states that results for moderate to severe forehead lines, frown lines and crow’s feet may last up to four months. Treatments should be spaced at least 90 days apart.

Individual experiences can vary.

And here’s an important distinction:

Movement beginning to return doesn’t necessarily mean you’re completely back to baseline.

You may gradually notice more expression before your original crow’s feet have fully returned.

That’s one reason patients sometimes think:

“My Botox only lasted six weeks.”

That deserves a deeper conversation, which we’ll cover in:

Why Does My Botox Wear Off So Fast?

What If One Side Has More Crow’s Feet Than the Other?

Welcome to having a human face.

Most people aren’t perfectly symmetrical.

You may:

• Smile more strongly on one side
• Squint differently on one side
• Naturally have different eyebrow positions
• Have different patterns of sun exposure
• Sleep predominantly on one side
• Simply have slightly different anatomy from left to right

That’s why we want to look at your face while you’re smiling, not simply assume both sides behave identically.

One of the easiest mistakes patients can make is comparing themselves to a treatment chart without considering their own facial movement.

Are Crow’s Feet Worse From Living in Arizona?

Living in Arizona doesn’t automatically cause crow’s feet.

But our environment does make sun protection especially important.

Ultraviolet exposure contributes to photoaging and collagen changes within the skin.

And bright Arizona sunlight can mean plenty of squinting too.

That makes basic prevention surprisingly important:

• Daily broad-spectrum sunscreen
• Sunglasses
• Appropriate skincare
• Avoiding unnecessary UV exposure

Injectables can address muscle activity.

They don’t replace good skin habits.

If we’re investing in treating the lines, we should also protect the skin creating them.

At What Age Should You Start Botox for Crow’s Feet?

There isn’t a magic birthday.

Not 25.

Not 30.

Not 40.

Some people develop significant dynamic crow’s feet relatively early.

Others barely have them decades later.

Genetics, facial movement, skin quality, sun exposure and personal preference all matter.

A better question is:

“Do these lines bother me enough that I want to treat them?”

Cosmetic treatment isn’t a requirement.

You’re not “behind” because you haven’t started Botox.

And you’re not automatically too young because a wrinkle showed up before you expected it.

The treatment should make sense for you, not an arbitrary age.

Is Preventative Botox for Crow’s Feet Worth It?

The idea behind so-called preventative Botox is that reducing repetitive muscle activity may reduce the repeated folding contributing to wrinkle development.

But we don’t think everyone needs to start injecting their face simply because they reached a certain age.

If you barely have visible movement and aren’t concerned about it, there may be nothing meaningful to treat.

If you already have significant dynamic lines and they bother you, that’s a more useful conversation.

Treat the patient—not the trend.

Does Botox Make Crow’s Feet Worse When It Wears Off?

Botox doesn’t create an obligation to continue treatment forever.

Because its effect is temporary, muscle activity gradually returns.

As that happens, the lines associated with the muscle movement can gradually return as well.

That can sometimes feel dramatic because you’ve spent several months looking at smoother skin.

But seeing your baseline again is not the same thing as Botox having “ruined” your skin.

We’ll tackle this myth directly in another Cluster 1 article:

Does Botox Make Wrinkles Worse When It Wears Off?

Should Men Get Botox for Crow’s Feet?

If crow’s feet bother you and you’re an appropriate candidate, gender isn’t the deciding factor.

Men smile.

Men squint.

Men develop lateral eye lines.

Treatment planning still depends on:

• Anatomy
• Muscle activity
• Facial proportions
• Goals
• Medical history

The desired aesthetic may also differ.

Some male patients specifically want to retain stronger expression.

Some don’t.

Again:

Ask the patient what they want instead of deciding for them.

Can I Treat Crow’s Feet Without Treating My Forehead?

Crow’s feet are an FDA-approved BOTOX Cosmetic treatment area on their own.

Whether you should also treat other areas depends on your concerns and your provider’s evaluation.

Maybe the crow’s feet are the only thing bothering you.

Great.

Maybe you also have significant forehead and frown-line movement.

Then we can discuss the face more globally.

BOTOX Cosmetic’s currently marketed three-area treatment consists of 20 units for frown lines, 20 units for forehead lines and 24 units for crow’s feet, totaling 64 units when all three approved upper-face areas are treated according to the labeled regimen.

That does not mean everyone needs all three areas.

It means those areas can be evaluated independently as part of a larger treatment plan.

What Should You Tell Your Injector Before Crow’s Feet Botox?

Don’t just sit down and say:

“Do whatever.”

Your preferences matter.

Tell your provider:

• Whether you’ve had Botox before
• Which neuromodulator you received
• Whether you liked the result
• How long you felt it lasted
• Whether you experienced dry eye or other problems
• Whether your smile felt different
• Whether you want significant relaxation or more movement
• Whether one side bothers you more
• Whether your main concern exists while smiling or at rest
• What medications and medical conditions your provider needs to know about

And if you don’t know what treatment you need?

That’s okay too.

You can simply say:

“This is what bothers me. What do you think is causing it?”

That’s actually one of our favorite ways to start.

Our Approach to Crow’s Feet at Allure Infinite Beauty

Someone comes in and says:

“I hate these wrinkles around my eyes.”

We don’t automatically want to respond:

“Great. Botox.”

First we want to see them.

Relax.

Smile.

Squint.

Then relax again.

Are we looking at strong dynamic crow’s feet?

Are we looking at etched lines in the skin?

Is the concern really under-eye crepiness?

Is there sun damage?

Is there laxity?

Is the patient bothered by movement—or by texture?

Those questions change the treatment conversation.

Sometimes Botox is exactly what makes sense.

Sometimes the better answer is:

Botox plus a skin treatment.

Sometimes what you’re calling crow’s feet isn’t primarily a Botox problem at all.

And we want to be comfortable telling you that.

Frequently Asked Questions About Botox for Crow’s Feet

How many units of Botox are used for crow’s feet?

The FDA-approved BOTOX Cosmetic dose for moderate to severe lateral canthal lines is 24 units total, or 12 units per side. Your treatment should be determined by an appropriately licensed medical provider after evaluating your anatomy and medical history.

Does Botox completely remove crow’s feet?

Botox temporarily reduces the muscle activity contributing to crow’s feet. Lines already visible while your face is relaxed may involve skin changes as well and may not disappear completely from Botox alone.

How soon does Botox work on crow’s feet?

BOTOX Cosmetic states that patients may begin noticing results within 1–2 days, with full results developing over time and evaluated at 30 days.

How long does crow’s feet Botox last?

Results may last up to approximately four months, although individual experiences vary.

Will Botox around my eyes make me look unnatural?

Treatment goals vary. Tell your provider how much expression you want to retain. A natural result isn’t simply about receiving the fewest possible units; anatomy, muscle movement and treatment planning also matter.

Can Botox fix crepey under-eye skin?

Botox primarily targets muscle activity. Crepey under-eye skin may involve collagen loss, laxity, texture and other skin changes that require a different treatment strategy.

Can I get Botox just for crow’s feet?

Crow’s feet are an FDA-approved BOTOX Cosmetic treatment area. Whether other areas should also be treated depends on your anatomy, concerns and provider’s evaluation.

Are Botox and Dysport the same for crow’s feet?

They are different botulinum toxin products. Their units are product-specific and should not be treated as interchangeable.

Is crow’s feet Botox safe?

BOTOX Cosmetic is an FDA-approved prescription treatment for moderate to severe lateral canthal lines in adults, but it carries potential risks, contraindications, warnings and side effects. Treatment should be performed by an appropriately licensed healthcare provider familiar with facial anatomy.

Can Botox cause dry eye?

Dry eye has been reported with BOTOX Cosmetic treatment in or near the orbicularis oculi muscle. Persistent eye irritation, light sensitivity or visual changes should be medically evaluated.
