Facial volume loss is the thinning of fat, bone, and collagen beneath the skin that leaves cheeks and temples looking hollow or flat. At Santa Barbara Face & Body in Santa Barbara, California, a board-certified facial plastic surgeon assesses which layer has been lost and restores it with filler, collagen-building injections, or fat transfer.
A hollow or flat face reflects loss of support underneath the skin. Fat pads shrink and slide, facial bone remodels, and collagen declines, so the surface has less to rest on. Restoring the look means replacing what was lost in the layer it was lost from.
What it is
Faces are built in layers: skin on top, then fat, then muscle and bone. The rounded look of a younger face comes mostly from the fat pads and the bone beneath them, not from the skin itself. When those deep layers thin, the skin has less to drape over, so cheeks flatten, temples sink, and the folds around the mouth deepen into shadows.
This is why a good moisturizer or a skin-tightening device can only do so much. They work on the surface, and the change is one or two layers down.
What causes it
- Fat pads shrink and shift. The compartments that pad the midface lose fat and slide downward with age, which hollows the upper cheek and heavies the lower face.
- Bone remodels. The facial skeleton loses projection over time, so there is less scaffold under the soft tissue.
- Collagen declines. The firm, springy support in the skin and deeper tissue thins with age, and sun exposure speeds it up.
A faster version can follow rapid weight loss from a GLP-1 medication, because fat leaves the face along with the body. That has its own path, covered on the Ozempic face page.
Where the volume went, and what replaces it
The useful question is not “which filler,” it is “which layer.” That is what a physician read answers, and it points to different tools.
| What you notice | Usually means | The route that fits |
|---|---|---|
| Flat upper cheek, a tired midface | Deep fat pad and bone loss | A hyaluronic acid filler or a collagen-building biostimulator, placed on the structure |
| Broad, diffuse thinning across the face | Widespread collagen and fat loss | Collagen-building injections over several sessions |
| A wish for a lasting, one-time restoration | A candidate for surgery | Moving your own fat into the face |
| Hollowing after fast weight loss | GLP-1 related volume loss | Assessed on the Ozempic face path |
The point is not the menu. It is that Dr. Pontius reads which layer is empty, and for surgical fat restoration works alongside Dr. Alain Polynice, so the plan follows your anatomy rather than a single product.
Why Santa Barbara Face & Body
Most practices that treat hollowing offer one tool and fit every face to it. Here all three real routes sit under one roof: precise hyaluronic acid filler, collagen-building biostimulators for diffuse loss, and surgical fat transfer for a lasting restoration. That range is what keeps the recommendation honest, because the plan can match your face instead of the practice’s inventory, and the physician reading you is the one who treats you.
When it is worth a consultation
Worth coming in if you
- See flattening in the cheeks or hollows at the temples
- Notice folds around the mouth reading as shadows, not just lines
- Have lost facial fullness after weight change
- Feel you look tired or drawn no matter how you rest
Better to talk it through first if you
- Are pregnant or breastfeeding
- Are early in a weight loss course and still changing, since timing matters
- Are unsure whether the issue is lost volume, a line, or loose skin, which the consultation sorts out
What to expect from a visit
Dr. Pontius looks at your face in motion and at rest, in good light, and maps which areas have lost support. You leave understanding which layer is involved and the realistic order of restoring it, whether that is a single treatment or a staged plan over time.
