Thermage FLX: 5 Real Patient Questions Answered by Our Dermatologist
From pain concerns to shot counts — Dr. JC shares honest, straightforward answers to the questions patients ask most before their Thermage treatment at BEAUNPL Clinic in Gangnam, Seoul.
-
Thermage tightens, Ultherapy lifts — Thermage uses RF for skin tightening; Ultherapy uses HIFU for lifting. Combining both yields the best results. -
Results appear immediately + peak at 3–6 months. Instant collagen contraction provides tightening, new collagen regeneration builds over months. -
Results last 6–12 months. Annual sessions recommended. Complementary treatments at 6 months can extend results. -
Pain is manageable. Numbing cream + optional sedation available. Slightly lower energy for comfort = still effective. -
600 vs 900 shots depends on your needs. 900 for 50s+ or face+neck; 600 for 30s with mild sagging.
Thermage FLX is one of the most well-known non-invasive skin tightening treatments in the world. Often called the “Korean actress secret,” it’s the treatment that keeps skin firm and youthful — recommended at least once a year for maintenance.
The saying goes: “There are people who’ve never tried Thermage, but nobody who’s only tried it once.” That’s how effective it can be. Yet some patients report underwhelming results. Below, I explain why — and answer the five most common questions our patients ask before their treatment.
What’s the difference between Thermage and Ultherapy?
Thermage uses radiofrequency (RF) energy to heat both the skin’s surface and deeper layers, stimulating collagen production. Its strengths are skin tightening and fine wrinkle improvement.
Ultherapy uses focused ultrasound energy (HIFU) to target the SMAS layer — the same layer surgeons adjust during a facelift. Its strengths are lifting and double chin reduction.
Thermage excels at tightening. Ultherapy excels at lifting. Many patients benefit from combining both.
Thermage vs Ultherapy Comparison
| Thermage FLX | Ultherapy | |
|---|---|---|
| Energy Type | Radiofrequency (RF) | Focused Ultrasound (HIFU) |
| Primary Effect | Skin tightening + fine wrinkles | Lifting + double chin reduction |
| Target Depth | Surface + deep dermis | SMAS layer (deepest) |
| Results Timeline | Immediate + peak at 3–6 months | Gradual, peak at 3–6 months |
| Duration | 6–12 months | 12–18 months |
| Pain Level | Mild–moderate (tingling) | Moderate (deeper sensation) |
| Downtime | None | None–minimal |
| Best For | Overall tightening, annual maintenance | Jawline lifting, sagging correction |
When will I see results from Thermage?
You’ll notice an immediate tightening effect right after treatment — like your skin has been gently “ironed.” This comes from instant collagen contraction.
Over the following weeks, new collagen continues to regenerate. Peak results typically appear at 3–6 months, with both tightening and gradual lifting becoming more visible.
Immediate results + progressive improvement over 3–6 months. Especially popular among patients in their 40s.
How long do Thermage results last?
Results typically last 6 months to 1 year. For best results, we recommend an annual session. Consistent treatment over the years yields the most impressive, cumulative results.
If budget is a concern, alternating Thermage with complementary lifting treatments extends results. For example, a Titanium Lifting session around the 6-month mark maintains results at lower cost.
6–12 months per session. Annual maintenance recommended. Complementary treatments can extend results.
How painful is Thermage?
Before treatment, we apply a coupling fluid that helps RF energy penetrate evenly while protecting the skin. The heat delivered deep into the skin causes a tingling or prickling sensation.
For patients concerned about discomfort, we can extend the numbing cream application time. For particularly sensitive patients, sedation is also available.
Important: slightly lowering energy intensity to manage pain will not significantly reduce effectiveness. What matters most is even distribution across the entire treatment area.
Manageable tingling sensation. Numbing cream + optional sedation available. Slightly lower energy for comfort = still effective.
600 shots vs. 900 shots — which should I choose?
More shots doesn’t automatically mean better results. The right count depends on: skin condition, degree of sagging, treatment area, skin sensitivity, and energy intensity.
-
900 shots — Recommended for 50s+, or face + neck treatment. Ideal for advanced sagging. -
600 shots — Great starting point for 30s with early fine wrinkles and mild sagging.
Shot count is personalized, not one-size-fits-all. Consultation determines the best option for you.
Choosing the Right Clinic
If you’re looking for a clinic to perform your Thermage treatment, verify these three things:
-
1
Experienced medical team — board-certified dermatologists with extensive Thermage experience -
2
Genuine Thermage tips — never reused (each tip has a fixed shot count and time-limited activation) -
3
Customized treatment design — energy levels and shot placement tailored to your unique facial structure
“In an era of slow aging, taking care of your skin is a gift to yourself. I always feel rewarded when I see the confidence our patients gain after their treatment.”
