The Perfect Duo: Thermage FLX vs. Ultraformer III HIFU – Which Is Better for Skin Tightening?

When it comes to non-invasive skin tightening and anti-aging treatments, Thermage FLX (also known as “Phoenix Thermage”) and Ultraformer III HIFU are two of the most sought-after choices. Many people, however, feel unsure when deciding between the two. What exactly are Thermage FLX and Ultraformer III? How do they differ? And which treatment is better suited to your skin condition for achieving the best lifting and tightening results?

1. Thermage FLX + Ultraformer III: The “Golden Duo” of Radiofrequency & Ultrasound

Since Thermage FLX and Ultraformer III each work at different skin depths and with different technologies, combining them—often called the “Golden Duo” of RF + HIFU—can deliver more complete rejuvenation results.

• Thermage FLX (Radiofrequency technology): Works mainly on the dermis, using 3D volumetric heating to tighten skin, smooth fine lines, refine pores, and stimulate new collagen for improved elasticity.
• Ultraformer III HIFU (High-Intensity Focused Ultrasound): Works primarily on the SMAS/fascia layer, using pinpoint thermal coagulation to lift sagging contours, reduce double chin, and restore definition.

By targeting different skin layers, the combination helps cover the full spectrum of aging concerns.

Thermage FLX: 3D Volumetric Heating for Visible Tightening

Thermage FLX is the fourth-generation flagship device in the Thermage family. Using monopolar radiofrequency, it delivers controlled heat deep into the dermis and parts of the SMAS layer through specialized treatment tips.

How it works:

• The heat causes existing collagen fibers to contract immediately, resulting in instant tightening and lifting.
• At the same time, it stimulates fibroblasts to produce new collagen over the following weeks to months, improving fine lines, wrinkles, jawline, and skin firmness.

This is why many patients notice a more lifted, firmer look right after their Thermage FLX session.

2. Ultraformer III HIFU: Pinpoint Heating for Deep Lifting

Unlike Thermage, Ultraformer III HIFU uses focused ultrasound energy to create thermal coagulation points at targeted depths of the skin, including the SMAS layer and different levels of the dermis.

Key benefits:

• Deep Lifting: Tightens the SMAS layer to improve jawline definition, double chin, and sagging skin.
• Jawline Refinement: Helps sculpt a sharper facial contour.
• Collagen Stimulation: Triggers collagen remodeling and regeneration for long-term skin firmness.

Ultraformer III offers a variety of treatment depths (1.5mm, 2.0mm for delicate eye areas, 3.0mm, 4.5mm, and deeper 6.0–13.0mm for the body), allowing tailored treatment for different areas and skin thickness.

3. Why Choose Thermage FLX Over HIFU?

Both Thermage FLX and HIFU are popular non-invasive treatments, but Thermage FLX offers more precise, stable, and comfortable results—especially when overall skin quality improvement is the priority.

At Perfect Medical, we use the 5th Generation Thermage FLX, which combines:

• Advanced AccuREP™ Technology: Automatically optimizes RF energy output according to your skin’s resistance, ensuring safer, more consistent results.
• Original Solta Medical Tips: Equipped with cooling and vibration technology, reducing discomfort compared to many HIFU devices.
• Professional Care: Every treatment is performed using a brand-new, single-use tip, unsealed in front of you for maximum hygiene and safety.

Thermage FLX is particularly effective for tightening loose skin, softening fine lines, and contouring around delicate areas like the eyes, nasolabial folds, and jawline—all with little to no downtime.
