Why a face loses volume
Underneath your skin sit pads of fat that give your face its shape. They are what makes a cheek look full and a temple look smooth, and they sit in distinct compartments rather than as one even layer.
With age those pads shrink and shift downward. That is why hollowness appears under the eyes and across the cheeks, and why the lower face can look heavier at the same time as the upper face looks emptier. It happens alongside collagen loss and bone change, and it is a large part of what reads as an older face.
Almost nothing in a bottle addresses that layer. Retinoids, peptides and vitamin C all work on the skin itself. Volufiline is one of the few cosmetic ingredients aimed at the fat beneath it.
How Volufiline works
Volufiline is a combination of two things: a compound called sarsasapogenin, which comes from the root of a plant used in traditional Chinese medicine, and a carrier that helps it absorb.
It works on the fat cells sitting beneath where you apply it. Two things appear to happen. The existing fat cells store more fat, which is the material fat cells are designed to hold, and the cells become slightly more numerous.
More fat held in that small area means the tissue beneath your skin sits a little fuller, and the hollow above it looks less deep.
The effect is local. It happens where you put it rather than anywhere else, which is why you apply it to the specific areas you want fuller rather than across your whole face.
What the research shows
The testing behind Volufiline was carried out by the company that makes the ingredient, which is normal for a trade-named cosmetic ingredient and worth knowing when you weigh the claims.
In that testing, a five percent Volufiline product applied twice daily for two months measured around two percent more volume in the treated area. Two percent is a small number, and on a cheek it reads as a slight softening of hollowness rather than anything dramatic.
So this is an ingredient with a clever idea behind it and modest measured results. That is worth saying plainly, because volume loss is the area where people most hope a cream will do what an injection does.
Where it comes from
Sarsasapogenin comes from Anemarrhena asphodeloides, a plant whose root has been used in traditional Chinese medicine for a long time. Volufiline itself is produced under laboratory conditions so that a formula contains a known and consistent amount.
