Dysport: How It Compares to Botox and Who It Suits

Dysport is one of the most common alternatives to Botox, and the question patients ask about it is almost always the same: is it better, worse or just different? The honest answer is that it is mostly the same, with a few differences that can make it the better choice for a particular person or area.

What Dysport is

Dysport is a purified form of botulinum toxin type A, the same family as Botox. Injected in tiny amounts, it blocks the signal that tells a muscle to contract. The muscle relaxes, and the lines it creates when you frown, raise your brows or squint soften. It treats lines caused by movement. It does not fill static creases or replace lost volume, which is the job of dermal fillers.

How it differs from Botox

The active ingredient is closely related, but the products are manufactured differently and carry different accompanying proteins. That leads to a few practical differences.

Onset. Many patients notice Dysport beginning to work a little sooner. Both products take about two weeks to reach their full effect.
Spread. Dysport tends to diffuse slightly further from the injection point. Across a broad area like the forehead that can give a smooth, even result. In a small area close to the eye or lip, a more contained product is often preferred.
Units. Dysport is measured in its own units, and a Dysport dose always uses more of them than a Botox dose for the same effect. The number of units is not a measure of strength, so comparing the two counts directly is misleading.
Feel. Some people feel one product looks softer or more natural on them. That is personal, and the only way to know is to try it.

Where Dysport is used

Frown lines. The vertical lines between the brows are the area Dysport is approved for. See frown lines.
Forehead. Horizontal forehead lines respond well, and the gentle spread can suit this broad area. See forehead wrinkles.
Crow's feet. The lines at the outer corner of the eyes are a common area. See crow's feet.
Other areas. Neuromodulators are also used for bunny lines, lip lines, a subtle brow lift and jaw slimming. Which product suits each depends on the size of the area and how precise the placement needs to be.

What treatment is like

Treatment takes a few minutes. The areas are cleaned, sometimes numbed, and a fine needle places small amounts into the target muscles. Most people return to normal activity the same day. Small bumps settle within an hour, and minor bruising is possible. The first changes appear over the next few days, and the result is judged at around two weeks, when any small adjustment can be made. The guide to aftercare covers what to avoid on the first day.

How long results last

Results usually last around three to four months before muscle movement gradually returns. Strong muscles, a fast metabolism and a low dose can shorten that. The guide to how long Botox lasts explains why, and the same principles apply to Dysport.

Risks and side effects

Dysport is well studied and side effects are usually mild: redness, swelling or bruising at the injection points, and occasionally a headache. The more important risk is placement. If product spreads into a muscle it was not meant to reach, it can cause a temporary heavy brow or a drooping eyelid that lasts until the product wears off. That is why knowledge of facial anatomy matters more than the brand chosen. Treatment is not recommended during pregnancy or breastfeeding, or for people with certain neuromuscular conditions.

Dysport or Botox: how to choose

For most people, either product gives an excellent result in the right hands. Dysport can make sense if you want a slightly faster onset, if you are treating a broad area such as the forehead, or if your results with Botox have started to feel shorter. Botox or another product may suit small, precise areas better. If you are new to treatment, a lighter first dose such as baby Botox is a reasonable way to see how your face responds.

The short version

Dysport softens expression lines in the same way Botox does. It may work a little sooner and spread a little further, it is dosed in its own units, and it lasts about as long. Neither is simply better. The right choice depends on the area, the strength of the muscles and how your face has responded before.

Wondering whether Dysport or Botox is the better fit?

A consultation looks at the lines you want to soften, how strong those muscles are and how you have responded to treatment before, so the choice of product and dose is made for your face rather than by habit.

They are close relatives. Both are purified forms of botulinum toxin type A that relax the muscles behind expression lines. They are made differently, are dosed in different units and behave slightly differently once injected, but the result in most areas looks very similar.

Many patients notice Dysport starting to work a little sooner, often within a few days. The full effect of either product usually settles in over about two weeks, which is the right time to judge the result.

Most people see results for roughly three to four months, similar to Botox. Strong muscles, a fast metabolism and a low dose can shorten that, and regular treatment often helps results last a little longer over time.

Units are product specific. A Dysport unit is not equal to a Botox unit, so a Dysport dose always uses more units for the same effect. Comparing the number of units between the two products does not tell you anything about strength or value.

It is approved for the frown lines between the brows and is widely used for forehead lines and crow's feet. Because it can spread a little more, some injectors like it for broad areas such as the forehead and prefer a more contained product for small, precise areas.

Yes. Some people switch because they feel their results have shortened or simply to see whether they prefer the feel. The dose is recalculated for the new product rather than copied across.
