## Frequently asked questions

### What is the difference between SMAS and deep plane facelift?

SMAS facelift tightens the SMAS layer with sutures from ABOVE. Deep plane facelift dissects BENEATH the SMAS to release retaining ligaments, then lifts skin + fat + SMAS as one composite flap. Practical differences: SMAS lasts 5-7 years and can look 'pulled'; deep plane lasts 10-15 years and looks naturally repositioned. Deep plane costs 30-50% more.
