How It Works

HIFU Focal Points vs. Monopolar RF Bulk Heating

HIFU (Ultherapy): focal coagulation points at 1.5, 3.0 and 4.5 mmUltrasound converges below an untouched surface into rows of small thermal coagulation points at three fixed depths, the deepest in the SMAS. HIFU · focused ultrasoundUltherapy PRIME · micro-focused, visualisedEpidermisPapillary dermis0.3–1.5 mmReticular dermis1.5–3.0 mmSubcutis3.0–4.2 mmSMASfibromusculartransducer1.5 mm · 10 MHz3.0 mm · 7 MHz4.5 mm · 4 MHz · SMASsurface sparedDiscrete micro-coagulation points (about 60–70 °C) at fixeddepths; the 4.5 mm line reaches the SMAS that a surgicalfacelift tightens. Skin between the points is spared.
Monopolar RF (Thermage): volumetric bulk heating of the dermisRadiofrequency energy heats a broad volume of dermis and fibrous septae evenly under a cryogen-cooled surface; there are no focal points.

Figure · Ultherapy (HIFU) vs. Thermage (monopolar RF)HIFU places rows of small thermal coagulation points at set depths of 1.5, 3.0 and 4.5 mm, the last in the SMAS. Monopolar RF heats a broad volume of dermis evenly instead. Focal depths per the Ultherapy transducer specifications (4 / 7 / 10 MHz); layer thickness illustrative.

Field Notes

Frequently Asked Questions

What skin depth and anatomical layer does Thermage FLX target?

Thermage FLX (6.78 MHz Monopolar RF) targets Reticular Dermis 1.5–3.0mm · Fibrous Septae to ~4.0mm: Papillary Dermis (0.3–1.5mm), Reticular Dermis (1.5–3.0mm), Subcutaneous Fat (3.0–4.2mm). Capacitive monopolar RF delivers volumetric bulk heating to the reticular dermis and fibrous septae, contracting and remodelling collagen.

How painful is Thermage FLX, what is the downtime, and what is the evidence-based session interval?

Pain index 6/10. Optional topical numbing; integrated cryogen cooling and vibration with AccuREP tuning. Downtime: 0–24 hrs mild erythema. Interval: Annual single session (12–18 months).

How do I verify an authentic Thermage FLX machine and what is a fair price in Singapore?

Solta holographic seal on the tip packaging; Rep counter at 0 on the FLX screen; Tip discarded after your session. Each Total Tip 4.0 ships sealed with a Solta holographic authenticity label. Insist the tip is unsealed in front of you and that the rep counter reads zero before the first pulse. Beauty.net's 2026 Singapore benchmark for Thermage FLX (600 reps (Asian full face) or 900 reps (face + neck)) is a fair range of S$2,950–S$4,400 with a median of S$3,500, incl. 9% GST.
