The standard dose of Dysport for crow’s feet is 30 units per side, totaling 60 units for both eyes. This is the manufacturer’s recommended dose, with 10 units injected at each of three sites around the outer corner of each eye. Your actual dose may vary based on muscle strength, gender, and how deep your lines are.
The Standard Dosing Breakdown
Galderma, the company that makes Dysport, recommends a specific protocol for crow’s feet (called lateral canthal lines in clinical terms): three injection points per side, with 10 units at each point. That gives you 30 units per side and 60 units total for both eyes.
The three injection sites fan out from the outer corner of the eye, targeting the muscle that contracts when you smile or squint. Your injector places them within this muscle while staying far enough from the eye itself to minimize risks. Some providers use up to five injection points per side for people with lines that extend further, though the total unit count often stays in the same range.
Why Your Dose Might Differ
Sixty units is the starting point, not a universal number. Several factors push the dose up or down.
Men typically need more units than women. Male facial muscles tend to be thicker and stronger, which means it takes more product to relax them enough to smooth the skin. A man might need 70 to 80 units total where a woman does well with 60.
The depth of your wrinkles matters too. If your crow’s feet are visible even when your face is completely relaxed (static lines), you may need a higher dose or additional sessions to see meaningful improvement compared to someone whose lines only show up when smiling (dynamic lines). Age, skin thickness, and how expressive you are all play into the equation.
How Dysport Units Compare to Botox
If you’ve used Botox before, the unit numbers for Dysport will look higher, and that’s normal. Dysport and Botox are measured on different scales. The most widely supported conversion ratio is roughly 2.5 to 3 Dysport units for every 1 Botox unit, based on clinical research published in the National Library of Medicine. A typical Botox dose for crow’s feet is about 12 to 24 units total (both sides), which lines up with 60 units of Dysport when you apply the conversion.
This difference in unit numbering doesn’t mean Dysport is stronger or weaker. It simply reflects how the two products are manufactured and measured. The end result, when dosed correctly, is comparable.
What Results Look Like
Dysport tends to kick in faster than some other neurotoxins. Most people notice initial smoothing within 2 to 3 days, though full results take about 10 to 14 days to settle in. Once the treatment reaches its peak, you can expect the effect to last roughly 3 to 4 months before the muscle gradually regains its full movement and lines start returning.
Some people find that with consistent treatments over time, they can go slightly longer between sessions. The muscle adapts to being in a relaxed state, and lines may not return as aggressively after several rounds of treatment.
What 60 Units Typically Costs
Dysport is generally priced between $4 and $8 per unit, depending on your location and provider. At 60 units for crow’s feet, that puts the total cost somewhere between $240 and $480 per treatment. The type of provider you see affects pricing too. A plastic surgeon’s office will often charge more per unit than a nurse injector at a med spa, though the product itself is the same.
Since results last 3 to 4 months, most people budget for three to four treatments per year if they want to maintain smooth results year-round. Galderma runs a loyalty program called Aspire that offers rebates on repeat treatments, which can offset some of the ongoing cost.
Side Effects Around the Eyes
The most common side effects are mild: temporary redness, slight swelling, or tenderness at the injection sites. These typically resolve within a day or two.
The more notable risk specific to this area is eyelid drooping, which happens when the product migrates slightly from the intended muscle. This is uncommon with an experienced injector and resolves on its own as the Dysport wears off, but it can last several weeks. Temporary blurred vision, dry eyes, or light sensitivity are also possible. If you notice any changes in your vision or significant eye discomfort after treatment, contact your provider rather than waiting it out.
To reduce the chance of these issues, most injectors advise staying upright for a few hours after treatment and avoiding rubbing or pressing on the treated area for the rest of the day.
