Botox and Dysport are both botulinum toxin type A neuromodulators that relax the muscles behind expression lines, so the skin above them looks smoother and more refreshed. When dosed well, both give natural movement — not a frozen look. The main differences are practical: Dysport tends to act a little faster and spread a touch more, which suits broad areas like the forehead, while Botox is prized for precise, targeted placement. Both typically last 3–4 months. Because they're measured in different units, per-unit price isn't a fair comparison — total cost per treatment ends up similar, and the right pick depends on your anatomy and goals.
What Botox and Dysport have in common
It's easy to think of these as rivals, but they're more like close cousins. Both are purified forms of botulinum toxin type A, both are FDA-approved, and both work the same way: they temporarily soften the specific muscles that crease the skin when you frown, squint, or raise your brows. As those muscles relax, the dynamic lines above them ease.
Both treat the same common concerns — frown lines (the "11s") between the brows, horizontal forehead lines, and crow's feet around the eyes — and both are popular as early, "preventative" treatments for fine lines that are just starting to set in. Treatment with either is quick, usually 15–30 minutes, with little to no downtime. Many clients return to their normal day right after. And with both, results vary from person to person based on muscle strength, metabolism, and how the product is dosed and placed.
What is Botox?
Botox is the original, most recognized neurotoxin and the one most people have heard of by name. It's known for staying precisely where it's placed, which makes it a favorite for small, targeted areas where control matters — think a single stubborn frown line, fine lines around the lips, or careful brow shaping. That precision is a big part of why so many providers reach for it first.
Botox typically begins to take effect in about 3–5 days, with full results around two weeks after treatment, and results usually last 3–4 months. At USA Aesthetics, Botox is dosed and placed by Nidia Garcia, ARNP, who tailors the plan to your facial anatomy so the outcome looks like a well-rested version of you.
What is Dysport?
Dysport is also a botulinum toxin type A neuromodulator, and for many clients it's a genuine favorite. Two characteristics set it apart in everyday use. First, it often has a slightly quicker onset — many people notice softening in about 2–3 days. Second, it diffuses a bit more from each injection point, spreading smoothly across a wider zone. That gentle spread can be especially nice for broader areas like the forehead, where even, blended results are the goal.
Like Botox, Dysport generally lasts 3–4 months and involves little to no downtime. One ingredient note: Dysport contains a small amount of cow's-milk protein, so it isn't appropriate for clients with that allergy — something we screen for at your consultation.
Botox vs. Dysport: side-by-side
Here's a quick at-a-glance comparison of how the two tend to behave. Keep in mind these are general tendencies; your individual response is what we plan around.
| Botox | Dysport | |
|---|---|---|
| Onset | 3–5 days | 2–3 days (often faster) |
| Spread | Precise, stays put | Diffuses a bit more |
| Often chosen for | Small, targeted areas | Broader areas like the forehead |
| Typical longevity | 3–4 months | 3–4 months |
| Dosing units | Botox units | Dosed differently (not 1:1 with Botox) |
A note on units and pricing
This is the part that trips people up most, so it's worth being clear: Botox and Dysport are measured in different units. A "unit" of one is not the same as a "unit" of the other, so comparing per-unit prices is not apples-to-apples. At USA Aesthetics, Botox is $12 per unit and Dysport is $4 per unit — but because Dysport is dosed differently and you typically need more of its units to treat the same muscle, the total cost for a given treatment area ends up similar between the two.
What actually matters is the total for the areas you're treating, not the sticker price of a single unit. We're happy to walk you through the math at your consultation so the numbers are transparent before anything begins. We also offer Xeomin and Jeuveau as additional neurotoxin options if they're a better fit for your goals.
Which is right for you?
There's no universal "better" choice here — both are excellent, and the right one depends on you. As a general guide, Dysport may be appropriate when you're treating a broad area like the forehead, or when you'd like to see results a little sooner. Botox may be the better fit when precision matters most, such as fine, targeted work around the eyes or mouth. Some clients also simply respond a touch better to one over the other, which we learn over time.
A consultation determines candidacy and the best match for your anatomy and goals. During it, Nidia Garcia, ARNP reviews your facial movement, your history, and what you'd like to achieve, then recommends the product and dose that fit. Both are generally avoided during pregnancy or breastfeeding, with certain neuromuscular conditions, or with an allergy to the ingredients — which is part of why that one-on-one review matters.
What to expect
Whichever you choose, the visit itself is quick and comfortable. After a brief assessment, treatment usually takes 15–30 minutes. Most clients describe only a tiny pinch at each injection point, and many head straight back to their day afterward. You may notice small temporary bumps at the injection sites that settle within minutes.
From there, it's a waiting game of just a few days: Dysport often begins working around 2–3 days, Botox around 3–5, with both reaching full effect near the two-week mark and typically lasting 3–4 months. Results vary, and with consistent maintenance many clients find their results hold a little longer over time. We'll suggest a comfortable rhythm so you stay looking refreshed without overdoing it.
