In Depth
Cheek Filler in Detail
The midface is not one block of fat. Anatomical studies show it is divided into separate compartments, deep and superficial, that age at different rates. [1] Filler placed deep restores support from below; placed only near the surface, it adds weight to tissue that may already be sliding.
Bone matters too. With age the eye socket widens and the cheekbone and upper jaw lose some projection, so the soft tissue has less to rest on. [2] That is why deep, on-bone placement at the cheekbone and the side of the cheek is often the first layer of a cheek plan, with finer contouring above it only where needed.
Restraint is the difference between a supported cheek and an overfilled one. A cheek that projects too far forward or too low, or bulges when you smile, usually reflects too much product or product in the wrong plane. Dr. Sin Yong builds volume in stages and checks the face upright, smiling and in profile before adding more.
Cheek Concern, Usual Plan
| Concern | Usual plan | Note |
|---|---|---|
| Flat midface | Deep support at the cheekbone and mid-cheek | Volume built in stages |
| Deep nasolabial folds | Support the cheek above the fold first | Direct fold filling only if still needed |
| Under-eye hollow with flat cheeks | Cheek support, then tear trough if needed | Cheek support can reduce what the tear trough needs |
| Sagging without much volume loss | Lifting treatments | Filler can add weight to loose tissue |
| Narrow, angular upper face | Lateral cheek support | Soft width, in proportion |
A fold below the cheek is often a sign of what has changed above it.
What Happens on the Day
- AssessmentUpright, at rest, smiling and in profile. Dr. Sin Yong maps volume loss, descent and bone support on each side.
- Plan and productThe layers and products for each area are agreed with you, including whether the product can be dissolved.
- Numbing and placementNumbing cream, then deep placement on bone first, in small amounts, followed by any finer contouring.
- CheckThe face is checked upright and smiling before you leave.
- Review at two weeksSwelling settles and the result is compared with your photographs; small adjustments are made then.
Risks and Side Effects
- Swelling and bruising for a few days to a week
- Tenderness when chewing or smiling for a few days
- Asymmetry or irregularity, adjusted at review
- Overcorrection if too much is placed, which is why volume is built in stages
- Rarely, infection or a blocked blood vessel; vision effects after facial filler have been reported very rarely
Warning signs. Seek help immediately if you notice a change in vision, skin on the cheek or nose turning pale, grey or blotchy, or pain that increases rather than settles.
Aftercare
- Do not press or massage the cheeks unless told to
- Sleep on your back for a night or two if you can
- Avoid heavy exercise, saunas and alcohol for 24–48 hours
- Avoid facials and dental treatment for two weeks
