How long does it take for Botox to work?

The answer to this question is, “it depends.” Botox and Dysport takes two weeks to reach maximum benefit.

Onset of Botox and Dysport

The onset of Botox and Dysport is different.

  • For Botox, you will see it begin to relax wrinkles two weeks after the treatment.
  • For Dysport, you will see it begin to relax wrinkles between three to five days after the treatment.

Both are neuromodulators, which means they relax muscles that cause wrinkles by weakening their contractions. Botox and Dysport offers anti-wrinkle effects to reduce the appearance of aging.

Botox vs. Dysport

The best Botox and Dysport are neuromodulators. Both contain botulinum toxin, which is a neuromodulator that relaxes muscles. Botox is a trademarked name for botulinum toxin and is administered by your nurse injector in tiny amounts that work to relax the muscles responsible for facial wrinkles. Dysport also contains botulinum toxin and can be used by nurses or doctors who’ve been trained to inject it. Both are efficacious at treating fine lines and wrinkles.

While there’s some debate about how long it takes for Botox vs. Dysport to work, most studies suggest that both take about two weeks before noticeable results are visible.

How it works

Botox and Dysport are neuromodulators. They work by relaxing the muscles that cause wrinkles to form in the skin. The effects of Botox and Dysport last for about 3-4 months. These treatments can be repeated if you want more long-lasting results.

Botox and Dysport are cosmetic injections that treat frown lines between your eyebrows, crow’s feet around the eyes, forehead wrinkles (glabellar lines), and other signs of aging that develop over time as we age.

Full effect takes two weeks.

There’s a common misconception that Botox takes effect immediately, but it actually takes two weeks to reach its full benefit. Dysport is similar enough to Botox that the same rules apply: It also takes two weeks to reach full effect.

Botox works by temporarily paralyzing certain muscles in your face and smoothing out wrinkles as they relax. Although it’s not guaranteed to work for everyone, there are plenty of people who swear by this anti-wrinkle treatment and can’t imagine their lives without it!

Botox takes two weeks to reach maximum benefit.

Botox takes between two and three weeks to reach maximum benefit. This means that you will start noticing a difference in how your muscles look during this time. Your nurse injector will offer a follow-up appointment after two weeks to assess the results and provide touch-ups if required.
