What Is Thermage FLX & Ultherapy Prime?

RF and ultrasound tightening, matched to your face.

Thermage FLX uses monopolar radiofrequency and Ultherapy Prime uses focused ultrasound; both are non-surgical treatments intended to firm skin and support facial contours by stimulating collagen at depth while preserving the surface. Which technology suits you — or whether they are combined — is determined after a facial analysis.

How they differ

Two technologies, different reach.

Thermage FLX — RF

Radiofrequency heats a broad volume of tissue to encourage firmness and smoothing.

Focus RF energy

Ultherapy Prime — HIFU

Focused ultrasound targets deeper layers, including the SMAS, at precise depths.

Focus Ultrasound

Analysis decides

Your laxity, depth and goals decide which energy, or a combination.

Both are designed to preserve the skin surface with minimal downtime.

Frequently Asked

Thermage FLX & Ultherapy Prime in Busan
questions.

What is the difference between Thermage FLX and Ultherapy Prime?

Thermage FLX uses monopolar radiofrequency across a broad tissue volume, while Ultherapy Prime uses focused ultrasound to reach deeper, precise depths including the SMAS. Which suits you is decided after a facial analysis.

Can I have both?

In some cases the technologies are combined. Whether this is appropriate is determined at consultation.

Is there downtime?

Downtime is generally minimal. Temporary redness, swelling or tenderness may occur and settles.

Does it hurt?

Both involve heat or energy sensations; comfort settings are discussed before treatment.

How long do results last?

Results develop over weeks to months and are not permanent; maintenance may be advised. Individual results vary.

How many sessions are needed?

RF and ultrasound tightening are often performed as single sessions with periodic maintenance, but your plan is set at consultation.

Is it a substitute for a facelift?

No. These are non-surgical options for mild to moderate laxity. Whether surgery suits you better is discussed at consultation.

Which areas can be treated?

Common areas include the lower face, jawline, cheeks, brow and neck, depending on the plan.

Am I a candidate?

Candidacy depends on your laxity, anatomy and goals, confirmed after examination.
