What are (bo)tox and Dysport?

(Bo)tox and Dysport are both wrinkle relaxers made from botulinum toxin type A. According to Anne Arundel Dermatology, they share the same general mechanism: they temporarily relax the muscles responsible for dynamic facial lines, the kind that form from squinting, frowning, and raising your brows over time.

(Bo)tox has the longest track record and was FDA approved in 2002, while Dysport followed in 2009. If you are new to injectables, our guide to what (bo)tox is and how it works is a good place to start.

How are (bo)tox and Dysport different?

The biggest differences come down to onset and diffusion. Dysport has a lighter molecular structure, so it spreads more widely under the skin and tends to show results a day or two sooner. (Bo)tox stays a bit more localized, which makes it easy to place with precision. Here is a side by side look.

Our guide on how long (bo)tox lasts goes deeper on protecting your results.

Which areas is each one best for?

Because Dysport diffuses more, it is a strong choice for broader zones like the forehead, and it is often used for masseter (jaw) treatments. (Bo)tox shines where precision matters, such as crow's feet and the glabellar (frown) lines between the brows.

(Bo)tox: crow's feet, forehead lines, and frown lines where precise placement matters.
Dysport: the forehead, masseter, and other larger treatment areas.

Which one is right for you?

No single neurotoxin is universally superior. The right pick depends on your anatomy, your goals, and your past response to injectables.
