Quick answer: Thermage and InMode Forma both use radiofrequency to tighten skin, but in different ways. Thermage is monopolar RF that heats deeper in one strong session, with results that often last about a year. Forma is gentle bipolar RF that warms the skin over a series of sessions. Thermage suits a single trip; Forma suits regular visits.
Key takeaways
- Thermage uses monopolar RF; Forma uses bipolar RF.
- Thermage reaches deeper and is usually done once a year.
- Forma heats more gently and is usually done as a series.
- Forma feels like a warm massage; Thermage has short hot pulses.
- Both have almost no downtime.
What is Thermage?
Thermage FLX, made by Solta Medical, uses monopolar radiofrequency. Energy passes from the tip deep into the skin and the tissue below, heating a large volume at once. This tightens collagen and stimulates new collagen over two to six months. One session is usually enough for a visible change, and results often last about a year. Thermage has FDA clearance for wrinkles and fine lines, including around the eyes.
What is InMode Forma?
Forma is a radiofrequency handpiece made by InMode. It uses bipolar RF, where energy travels between two points on the same tip, so the heat stays closer to the surface. Forma has built-in temperature control that keeps the skin at a set warm level, usually around 40 to 43°C, while the doctor glides the tip across the face. The heat tightens collagen and improves skin texture and glow. Because each session is gentle, Forma is often done as a series of several sessions.
How do Thermage and Forma compare?
- Type of RF: Thermage monopolar; Forma bipolar.
- Depth: Thermage deeper and broader; Forma more superficial.
- Sessions: Thermage usually once a year; Forma often 3 to 6 sessions, about one to two weeks apart.
- Comfort: Thermage short hot pulses; Forma steady warmth like a hot stone massage.
- Best for: Thermage for loose skin and stronger tightening; Forma for glow, texture and gentle maintenance.
- Downtime: both minimal, with temporary redness.
Which is better for a short trip?
If you are only in Seoul for a few days, Thermage is usually more practical. One session can give a noticeable result that keeps improving after you fly home. Forma works best when repeated, so it suits people who live in Korea or visit often. Some visitors have one Forma session for an instant glow before an event.
Which is better for loose skin?
For skin that has started to loosen along the jawline, cheeks or neck, Thermage is generally the stronger option because it heats deeper tissue. Forma can improve mild laxity, but its effect is gentler and builds over several sessions.
Which is better for skin glow and texture?
Forma is popular for brighter, smoother skin. The gentle heat improves circulation and collagen in the upper skin, so many people notice a fresher look right after the session. It is often combined with Mini FX for fat reduction under the chin in what Koreans call InMode lifting.
Can you combine them?
Yes. Some people have Thermage once a year and Forma sessions in between to keep the skin firm and glowing. Both can also be combined with Ultherapy, which lifts the deeper SMAS layer. Your doctor will plan the timing so treatments support each other.
What is the downtime?
Downtime is very low for both. After Thermage, mild redness or swelling may last a few hours to a day. After Forma, the skin may look pink for an hour or two. You can usually wear makeup and go out the same day.
Is it safe?
Both are widely used and safe in experienced hands. Rare risks include burns, blisters or temporary bumps. Tell your doctor about metal implants, pacemakers, pregnancy or recent fillers, as these can affect radiofrequency treatment.
How to choose between them
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Radiofrequency treatments are among the most popular. Choose Thermage if you want one stronger treatment for loose skin, and Forma if you want gentle, regular care for glow and texture. A face check helps your doctor decide.
