Visual planning tool
Lip filler simulator
A lip filler simulator creates planning previews of the same face with different filler amounts beside the untreated photo. Upload your own image or start with a stored demo face, then compare the visual direction at each setting. It is a consultation aid, not a predicted or medical result.

How the simulator works
The demo comparison above shows Russian lips with Juvederm Ultra XC. Choose a face and amount to compare the untreated photo with that preview. Product links later on this page open separate treatment pages. Upload your own photo to compare looks in the paid simulator. The preview is an illustration of a possible direction, not a guarantee of what your result will look like.
Compare different filler products
LookPrep previews multiple filler products, each with different characteristics. Compare hydrating fillers, volumizing fillers, and flexible-movement options to explore which direction appeals to you.
Looking for a lip flip preview?
Lip filler and lip flip are separate preview modes in LookPrep. This page compares filler amounts; the lip flip simulator uses its own preview settings. Both are visual planning tools, not predictions of treatment results.
LookPrep is not a medical provider and does not sell or administer treatment. A preview is an illustration, not a prediction. Product choice, amount, placement and candidacy are decisions for a qualified clinician, and the product labeling and consent discussion remain the authority.
