Neuromodulators soften the lines that appear when you move your face, such as frown lines, forehead lines and crow's feet. They all work the same way, by relaxing the specific muscle creating the crease.

How they differ

The differences are practical rather than dramatic. Some act faster. Some spread further from each injection point, which suits broader areas. One uses a pure formulation without accessory proteins. One lasts noticeably longer, which means fewer appointments each year.

Choosing between them

Your muscle strength, your treatment history and how often you want to come in matter more than the brand name. Dosing units are not interchangeable between products, so your injector converts rather than matching one to one.

Neuromodulators treat movement, not volume. If your concern is hollowness, or a fold that is there even when your face is still, dermal filler is the right tool. Many patients use both.
