One adds shape on the day. The other asks your skin to rebuild over months. How we choose between them.

Both can help a face that has lost something. They work on very different timelines, and the right choice depends on how patient you want to be.
In short
Filler restores shape in one place, on the day.
Biostimulators build collagen over three to four months.
We decide by where you lost volume and how thin the skin is.
Filler
Filler restores shape in a specific place, and you see it the same day. It suits a defined loss of volume, such as the cheek or temple. Most plans use one or two syringes.
Visible the same day
Precise, and suited to one area
Can be adjusted at your check-in
Filler changes one place, and you can see it before you leave.
Biostimulators
These prompt your skin to make collagen over three to four months. They suit skin that has thinned across a wider area, and the change is gradual enough that most people only notice being told they look well.
Filler answers where. A biostimulator answers how much is left to work with. Often the second question comes first.

We check how much your skin has thinned before choosing.
How we decide
We look at where you have lost volume and how much your skin has thinned, then ask how patient you want to be. If you need both, we build the skin first and add shape after.
When to come in
If your face looks tired and you can’t say why, come in before you choose. A look under the same light usually answers it.
General information, not medical advice. Your clinician will confirm what suits your skin.
