Shot Counts and Lines Explained: Ultherapy vs Thermage

Short answer: Ultherapy is measured in lines (each line is a row of focused ultrasound points); Thermage FLX in shots (each shot is one RF pulse from the tip). Typical full-face treatments use roughly 300–600 Ultherapy lines or about 600 Thermage shots. Where the energy goes matters more than the total.

1. Ultherapy lines

Lines are split between depths: 4.5 mm for the SMAS lift, 3.0 mm for deep dermis and 1.5 mm for fine texture. A thin face may need fewer deep lines to avoid hollowing. How many lines do I need?

2. Thermage shots

Shots are counted by the single-use tip. More passes go along the jawline and cheeks; lighter passes around the eyes. How many shots do I need?

3. Why more is not always better

  • Too much deep energy on a thin face can reduce volume
  • Even heating matters more than total count for Thermage
  • Comfort and safety limit energy per area

4. Ask for it in writing

Before treatment, confirm the number of lines or shots, the device brand and who will perform it.

Conclusion

Think in distribution, not totals. That is the basis of our Design Lift.
