One relaxes movement, one improves the skin itself. Which you need depends on what you see.

People often ask for one when they want the other. A tired look can come from movement, from dry skin or from both, and each needs a different tool.
In short
Lines that only appear when you move point to a neuromodulator.
Flat, dehydrated skin at rest points to a booster.
They can be combined, one at a time.
Look at your face at rest
Relax your face in a mirror, then frown and smile. If a line is only there when you move, a neuromodulator is usually the right tool. It softens the movement that folds the skin, and it starts at 10 to 25 units for most areas.
Forehead lines that fade when you relax
Frown lines between the brows
Crow’s feet when you smile
A line that appears with movement tells us where to start.
Look at your skin in daylight
Now look at your skin by a window. If it looks flat, dehydrated or crepey, movement is not the problem. A booster adds hydration from inside the skin and does not change your expression.
Results build over a course of sessions, so this is the slower of the two choices.
If you can’t tell which one you need, that is what the first visit is for. We would rather talk you out of something than sell it.
Theo Brandt, neuromodulators and filler
Boosters work on the quality of the skin, not on your expression.
Sometimes both
They work on different things, so they can be combined. We start with whichever changes more for you, then look again at twelve weeks and decide whether the second one is still needed.
When to come in
If you have an event coming, come in at least four weeks before. It gives every treatment time to settle.
