Crow’s feet form from tiny muscles contracting at the outer corner of the eyes, which happens every time you smile, laugh or squint, according to Cleveland Clinic.
Over time, sun exposure and the natural decline in collagen and elastin with age make these lines more visible, even at rest. Cleveland Clinic also lists genetics and emotions such as stress among the factors that shape how early and how deeply they develop.
Yes. According to its prescribing information, Botox Cosmetic is indicated in adult patients for the temporary improvement in the appearance of moderate to severe lateral canthal lines, the clinical name for crow’s feet, associated with orbicularis oculi activity.

Crow’s feet are one of four areas Botox Cosmetic is FDA-approved to treat, alongside frown lines (glabellar lines), forehead lines and platysma (neck) bands. It works by temporarily relaxing the targeted muscle so it contracts less, which softens the lines that form from that movement. For pricing and everything else about the treatment, see our Botox page.
| Treatment Area | Label Total |
|---|---|
| Crow’s feet (lateral canthal lines) alone | 24 units (12 per side) |
| Crow’s feet with frown lines (glabellar lines) | 44 units |
| Crow’s feet, frown lines and forehead lines together | 64 units |
The label dose for crow’s feet alone is 4 units injected into 3 sites per side, for a total of 24 units. Your nurse injector sets your dose at your visit based on your anatomy and goals. For dosing in other areas of the face, see our Botox units by area guide.

At every InjectCo clinic, Botox is $7.77 per unit with membership ($24.99/month), or $12 per unit. As an example built on the label dose, 24 units come to $186.48 at $7.77 per unit, or $288 at $12 per unit. Your nurse sets your actual dose at your visit, which may be higher or lower depending on your anatomy and whether you treat crow’s feet alone or with another area.

According to the American Academy of Dermatology, the effect lasts about 3 to 4 months, and sometimes longer. The Botox Cosmetic label notes that dosing more often than every 3 months has not been clinically evaluated, so repeat treatments are spaced at least that far apart. The AAD adds that with repeat treatment for lines and wrinkles, the muscle may thin, leading to longer-lasting results. For tips, see our guide on how to make Botox last longer.
The Botox Cosmetic label lists eyelid swelling (eyelid edema) as the adverse reaction reported for crow’s feet treatment. The American Academy of Dermatology notes that swelling, redness, soreness and bruising can happen, and that weakness in a neighboring muscle, leading to a temporarily droopy brow or eyelid, is rare.

Botox Cosmetic carries a boxed warning: the effects of Botox and all botulinum toxin products may spread from the injection area to other parts of the body, and swallowing and breathing difficulties can be life threatening. Get medical help right away if you have trouble swallowing, speaking or breathing after treatment. For a fuller list of possible reactions, see our guide on Botox side effects.
The label says Botox Cosmetic should not be used by anyone allergic to any botulinum toxin product or when there is an infection at the planned injection site. It also states there are no studies or adequate data from postmarketing surveillance on the developmental risk of Botox Cosmetic in pregnant women. Tell your nurse if you are pregnant or breastfeeding.
Ask your nurse injector how crow’s feet Botox may affect the look of your eyes before your treatment. The answer depends on your anatomy, the area treated and your dose, so your nurse walks you through it at your visit.
If you are not ready for an injectable, Cleveland Clinic lists a few other options.
Daily sunscreen of SPF 30 or higher protects your skin from UV rays, and sunglasses or a wide-brimmed hat shield your eyes and help prevent squinting.
Retinol, a vitamin A derivative sold over the counter, stimulates the production of collagen and elastin; irritation is a possible side effect, especially at first or at high strengths.
Chemical peels and regular exfoliation can improve the look of fine lines. These work on the skin’s surface rather than on the muscle movement that creates expression lines.
The label dose for crow’s feet alone is 24 units total, 12 units per side, given as 4 units into 3 sites per side. If you also treat frown lines at the same visit, the combined label dose is 44 units. Your nurse injector sets your exact dose at your visit based on your anatomy and goals.
At InjectCo, Botox is $7.77 per unit with membership ($24.99/month), or $12 per unit. Using the label dose of 24 units as an example, that comes to $186.48 with membership or $288 at $12 per unit. Your actual total depends on your dose, which your nurse sets at your visit.
Yes. Botox Cosmetic is FDA-approved for the temporary improvement of moderate to severe crow’s feet, and it works by relaxing the muscle behind the lines that form when you smile or squint. Results are temporary, lasting about 3 to 4 months according to the American Academy of Dermatology, so treatment is repeated over time.
Results typically last about 3 to 4 months, and sometimes longer, according to the American Academy of Dermatology. The Botox Cosmetic label notes that dosing more often than every 3 months has not been clinically evaluated. Individual results vary, and the AAD says repeat treatment may thin the muscle, leading to longer-lasting results.
Yes. The Botox Cosmetic label includes a combined dose for crow’s feet, frown lines and forehead lines treated together, for a total of 64 units across all three areas. Each area is dosed according to its own labeled amount within that total. Your nurse injector can walk you through a combined plan for your goals.
The adverse reaction the Botox Cosmetic label reports for crow’s feet treatment is eyelid swelling (eyelid edema). Bruising, redness, soreness and swelling can happen at the injection sites, according to the American Academy of Dermatology, and a temporarily droopy brow or eyelid from weakness in a nearby muscle is rare.
Crow’s feet Botox comes down to a few facts: it is FDA-approved for this area, the label dose is 24 units, results last about 3 to 4 months, and at InjectCo it is $7.77 per unit with membership, or $12 per unit. What varies is your anatomy, how deep your lines are and whether you treat crow’s feet alone or with frown or forehead lines, which is why your nurse injector sets your dose at your visit.
