Neuromodulators are among the most popular non-surgical cosmetic treatments for smoothing wrinkles. Botox and Dysport injections have long led the market, and Daxxify has since joined them with a promise of longer-lasting results. All three soften expression lines, but they differ in how fast they work, how far they spread, and how long results last. Knowing these differences can help you have a more informed conversation with your provider.

How Neuromodulators Work
Botox, Dysport, and Daxxify all contain botulinum toxin type A. When injected in small, controlled doses, the toxin blocks nerve signals that tell certain muscles to contract. Those muscles relax, and the dynamic wrinkles they create — such as frown lines, forehead lines, and crow’s feet — appear smoother.
The active ingredient is similar in each product. The formulations differ, and that changes how each one behaves.
Botox
Botox (onabotulinumtoxinA) is the most studied neuromodulator and is FDA-approved for frown lines, forehead lines, crow’s feet, and neck bands.
- Onset: Results usually appear within three to five days, with full effect at about two weeks.
- Duration: Typically three to four months.
- Spread: Fairly precise, which makes it well suited for small, targeted areas.
Dysport
Dysport (abobotulinumtoxinA) is FDA-approved for frown lines. Its units are dosed differently than Botox, so the numbers can’t be compared one-to-one.
- Onset: Often faster, with some people seeing results in two to three days.
- Duration: Around three to four months, similar to Botox.
- Spread: Tends to diffuse more widely, which can help with larger areas like the forehead.
Daxxify
Daxxify (daxibotulinumtoxinA-lanm) is FDA-approved for frown lines. It uses a stabilizing peptide in place of human serum albumin and contains no human or animal-derived ingredients.
- Onset: Many patients see changes within one to two days.
- Duration: Results tend to last longer than traditional neuromodulators, with some patients experiencing effects for up to several months beyond the typical window.
- Spread: Comparable to Botox, though clinical experience with it continues to grow.
The trade-off is cost. Daxxify often costs more per session, though fewer yearly visits may balance that out.
Ideal Candidates for Each
The best choice depends on your goals, budget, and treatment history.
- Botox suits people who want a well-established product with a long safety record and precise placement around the eyes or brows.
- Dysport may appeal to those who want quicker results or need coverage across a broader area.
- Daxxify fits patients who want fewer appointments each year or whose results from other neuromodulators fade too quickly.
In general, these treatments aren’t recommended for people who are pregnant or breastfeeding, have certain neuromuscular conditions, or are allergic to any ingredients.
What to Expect
A typical session takes 10 to 20 minutes. Your provider cleans the skin and uses a fine needle to inject small amounts into specific muscles. Most people return to normal activities right away.
Common side effects include:
- Mild redness, swelling, or bruising at injection sites
- Headache
- Temporary eyelid or brow drooping in some cases
Providers often advise avoiding lying down, heavy exercise, and rubbing the treated area for several hours afterward. Choosing an experienced, licensed injector greatly reduces the risk of uneven results or complications.
Which Is Right for You?
Botox, Dysport, and Daxxify all relax facial muscles to smooth dynamic wrinkles, but each has distinct strengths. Botox offers precision and a well-established track record. Dysport may work slightly faster and spread more evenly across larger areas. Daxxify stands out for its quick onset and longer-lasting results, with a higher price per treatment. The right option depends on individual goals, anatomy, budget, and medical history.
