Thermage FLX results commonly last about 12 months, and for some people up to around 2 years. Thermage FLX is an FDA-cleared monopolar radiofrequency treatment that tightens skin by stimulating collagen, so improvement builds over 2–6 months after one session. Longevity depends on age, skin quality and lifestyle. Results vary by individual.

Why do Thermage FLX results take time to appear?
Thermage FLX heats the deeper layers of the skin with radiofrequency energy. Some tightening may be visible right away as existing collagen contracts, but the main effect comes from new collagen that forms over the following weeks and months. This is why many people see the most change between about two and six months after their session.
What affects how long Thermage lasts?
- Age and starting skin quality: younger skin with mild laxity often holds results longer than very thin or heavily sagging skin.
- Lifestyle: UV exposure, smoking, poor sleep and large weight changes speed collagen loss.
- Treatment plan: the number of shots and coverage of the treated area matter. See why shot count matters.
- Natural aging: Thermage does not stop aging; it resets the starting point, and the skin continues to age from there.
How often should Thermage FLX be repeated?
Many patients choose a maintenance session about every 12–18 months, ideally before the effect has fully faded. Some combine Thermage with ultrasound lifting, for example alternating with Ultherapy Prime, because each works at different depths. Our Ultherapy Prime vs Thermage FLX comparison explains the differences.
How can you make results last longer?
- Wear broad-spectrum sunscreen every day.
- Keep skin hydrated and consider skin boosters to support skin quality.
- Maintain a stable weight and avoid smoking.
- Follow the clinic's aftercare guidance; see aftercare after Ultherapy and Thermage.
At Re:berry Hongdae, a doctor assesses your skin first and explains what change and longevity are realistic for you. Pricing depends on the area and shot count and is confirmed in writing at consultation.
Is Thermage FLX worth repeating?
Many patients find a yearly or 18-month session keeps skin looking consistently firm, rather than waiting for a large decline and trying to reverse it. Whether repeating suits you depends on how your skin responded the first time, which the doctor reviews at a follow-up.

Related questions
Is one Thermage FLX session enough?
For many people, one session gives a noticeable tightening effect that develops over several months. Others with more laxity may benefit from combining Thermage with other lifting treatments. Maintenance is typically planned once the effect begins to fade, often around a year later.
Does Thermage last longer than Ultherapy?
Both are commonly described as lasting about a year or more, and individual response varies more than the device. Thermage focuses on skin tightening through radiofrequency, while Ultherapy targets deeper lifting layers with ultrasound. Many patients alternate or combine them.
Can I see Thermage results immediately?
Some people notice mild tightening right after treatment, but this is often subtle. The more meaningful change comes from collagen remodeling over 2–6 months, so the doctor usually evaluates results a few months after your session. Photos taken before treatment make the gradual change easier to see.
