Overfilled face & pillow face — illustrative model, not a patient

This hub lists every page on drsinyong.com about filler that has gone wrong or simply gone too far: pillow face, under-eye lumps, puffiness, nodules after Ellansé or Sculptra, migration and the Tyndall effect. Dr Sin Yong images earlier filler with ultrasound before anything is dissolved or added; hyaluronic acid is treated with ultrasound-guided hyaluronidase, and non-dissolvable material with the Time Freeze Laser LCLR®.

Key facts
First step
Ultrasound to see where the filler is, how deep and what it looks like
Hyaluronic acid
Ultrasound-guided hyaluronidase into the deposit, smallest effective dose
Not HA
Time Freeze Laser LCLR®, built to target over-stimulated tissue and take away the excess
Rule
More filler cannot fix a face that already has too much

Frequently Asked Questions

No. Hyaluronidase only dissolves hyaluronic acid. Ellansé, Sculptra, Radiesse, collagen gels and silicone need a different approach; Dr Sin Yong uses the Time Freeze Laser LCLR® for over-stimulated tissue after biostimulators and refers discrete lumps for excision where appropriate.

It helps but is not essential. Ultrasound usually shows whether the material behaves like hyaluronic acid or a collagen stimulator, its depth and whether it is one deposit or several.
