Thermage FLX vs Ultherapy: Which Suits Your Type of Skin Laxity?

This is a side-by-side decision guide: if you are choosing between Thermage FLX and Ultherapy, the deciding factor is usually where and how your skin has loosened. Thermage uses radiofrequency to tighten skin and refine texture on the face, eyes and body; Ultherapy focuses ultrasound at the deeper SMAS layer to lift the brow, jawline and neck. A physician assessment decides; see Thermage FLX and Ultherapy. If you want to understand Ultherapy on its own instead, see What is Ultherapy? For body areas, see Ultherapy Body.

If you're researching non-surgical skin tightening in Richmond or Vancouver, two treatments are often compared: Thermage FLX and Ultherapy. Both are physician-administered treatments with published clinical research, but they work in fundamentally different ways. Understanding these differences helps when choosing the treatment that suits your skin concerns.

At RAAC Richmond Anti-Aging Clinic, Dr. Charles Jiang has over 29 years of medical experience and performs skin tightening procedures using both technologies. This guide reflects his clinical expertise and honest assessment of each platform.

How do Thermage FLX and Ultherapy work?

Thermage FLX heats the deeper skin and underlying tissue with radiofrequency so collagen contracts and then rebuilds, while Ultherapy uses visualized, focused ultrasound to heat precise points at set depths, including the SMAS layer tightened in a facelift.

Thermage FLX: Radiofrequency (RF) Energy

Thermage FLX uses monopolar radiofrequency energy to deliver volumetric heating to the deep dermis and subcutaneous tissue. The RF energy heats collagen fibers to approximately 65-75°C, causing immediate collagen contraction followed by a prolonged period of new collagen synthesis (neocollagenesis).

Key features of Thermage FLX:

• 5th generation technology with AccuREP™ tuning system
• Vibration-based comfort technology replaces older cooling-only systems
• Treats all skin layers simultaneously — epidermis through subcutaneous fat
• Can be used across skin types (Fitzpatrick I-VI), including darker skin tones, after assessment
• Single-pass treatment protocol reduces treatment time significantly

Ultherapy: Micro-Focused Ultrasound (MFU)

Ultherapy uses micro-focused ultrasound with visualization (MFU-V) to deliver precise thermal energy to specific tissue depths. It creates thermal coagulation points (TCPs) at targeted depths — including the SMAS layer (superficial muscular aponeurotic system), which is the same tissue layer surgeons tighten during a facelift.

Key features of Ultherapy:

• A medical-grade device for non-invasive lifting of the brow, chin, and neck
• Real-time ultrasound visualization allows practitioners to see tissue layers
• Targets specific depths: 1.5mm, 3.0mm, and 4.5mm transducers
• Creates focused micro-injuries that trigger deep tissue remodeling
• Designed mainly for lifting rather than just tightening

What is the difference between Thermage and Ultherapy?

In short, Thermage is mainly for tightening and texture, including the eyes and body, while Ultherapy is mainly for lifting at deeper layers; both typically need one session a year and peak at around 3 to 6 months.

Which Is Better for Your Specific Concerns?

Choose Thermage FLX If You Want:

• Overall skin tightening and texture improvement across the face
• Treatment for body areas (abdomen, arms, thighs, knees) — Thermage has body-specific tips
• Jawline contouring and reduction of jowling
• An option that can be considered for darker skin tones, after assessment
• Eyelid tightening — Thermage has a specialized eye tip (0.25 cm²) that is used on the upper and lower eyelid area (cost for the eye area is explained at consultation)
• Improved skin texture and pore size in addition to tightening

Choose Ultherapy If You Want:

• Brow lifting — Ultherapy is often used to lift drooping eyebrows
• Neck and submental (under-chin) lifting — deep SMAS-level treatment
• Jawline definition with a true lifting vector
• Treatment supported by clinical evidence for lifting specifically
• Precise depth targeting — useful when specific tissue planes need treatment

Consider Combining Both:

Combining both technologies may be considered for some patients. A common protocol:

• Ultherapy for deep lifting (SMAS layer) of the mid-face, jawline, and neck
• Thermage FLX for surface tightening, texture improvement, and eye area treatment

This combination works at several tissue depths without incisions or general anesthesia; it does not replicate a surgical result, and results vary.

Does Thermage or Ultherapy hurt more?

Ultherapy is generally the more uncomfortable of the two: most patients rate Thermage FLX around 3 to 5 out of 10 and Ultherapy around 5 to 7, and pain-relief options are available for Ultherapy.

Thermage FLX Comfort

The FLX generation includes several comfort-related changes compared with earlier Thermage versions:

• AccuREP™ technology automatically optimizes energy delivery for each pulse
• Vibration-integrated handpiece reduces pain perception (gate control theory)
• Most patients rate discomfort as 3-5 out of 10
• No numbing cream required in most cases (though available if preferred)
• Treatment can be performed with conversation — no sedation needed

Ultherapy Comfort

Ultherapy is generally considered the more uncomfortable of the two:

• Creates focused thermal injury points that can cause sharp, brief pain during delivery
• Most patients rate discomfort as 5-7 out of 10
• Pre-treatment strategies at RAAC: oral analgesic, optional topical numbing, Pro-Nox™ (nitrous oxide) available
• Pain is transient — felt only during energy delivery, not between pulses
• Dr. Jiang adjusts energy levels based on patient feedback to balance comfort and effect

When will I see results from Thermage or Ultherapy, and how long do they last?

Thermage may show mild tightening right away, while Ultherapy shows little change at first; both usually peak around 3 to 6 months and gradually soften over 12 to 24 months, so annual maintenance is common.

After Thermage FLX:

• Immediately: Mild tightening noticeable in many patients; slight redness (resolves in hours)
• Week 2-4: Skin feels firmer, smoother; makeup applies more evenly
• Month 2-3: Tightening along the jawline and midface may become visible
• Month 4-6: Peak results — most collagen remodeling has taken place
• Month 12-24: Results gradually soften; annual maintenance recommended

After Ultherapy:

• Immediately: No visible change; possible mild redness or swelling
• Week 2-4: Subtle changes begin; skin may feel slightly tighter
• Month 2-3: Progressive lifting becomes apparent
• Month 3-6: Peak results — most of the lifting and tightening effect is visible
• Month 12-24: Gradual decline; touch-up sessions extend results

Who Should Avoid These Treatments?

Both treatments are contraindicated for:

• Active skin infections or open wounds in the treatment area
• Pregnancy or breastfeeding
• Electronic implants (pacemakers, defibrillators) in the treatment area
• Severe cystic acne in the treatment zone

Thermage-specific: Patients with metallic implants in the treatment area should inform their physician.

Ultherapy-specific: Not recommended over areas with active cold sores (can trigger outbreaks).

How much do Thermage FLX and Ultherapy cost in Richmond?

Prices are discussed at consultation and depend on the area treated, such as full face, eyes, neck or body, and on the protocol, including whether the two are combined.

Prices reflect 2024-2025 rates at RAAC Richmond. Exact pricing depends on treatment area size and protocol.

Frequently Asked Questions

Q: Can I do both Thermage and Ultherapy at the same time? A: They can be combined but are typically performed 4-6 weeks apart to allow each technology to initiate its own collagen remodeling cascade without interference.

Q: How many sessions do I need? A: Both are designed as single-session treatments with annual maintenance. Some patients with significant laxity may benefit from a second session after 6 months.

Q: Will either treatment replace a facelift? A: Neither replaces surgery for advanced sagging. They are better suited to mild-to-moderate laxity, and the change is modest compared with surgery.

Q: I'm in my 30s — is it too early? A: Not necessarily. Some people start in their 30s or 40s, when laxity is mild; whether treatment makes sense now is assessed at consultation, and results vary.

Q: Which is better for Asian skin? A: Both can be used across skin types after a physician assessment. For some patients with typically thicker dermis and a robust collagen response, Thermage FLX may be considered.
