InMode versus Thermage: which should you choose for facial fat and a sagging jawline?
Full translation of the Korean article. Translation checked for completeness, numerical consistency and medical meaning; separate medical review of this translation is pending. Translation updated: 2026-10-28.
When choosing between InMode and Thermage, first check whether InMode means MiniFX or Forma. MiniFX targets localized contouring using suction and bipolar RF; Forma uses contact bipolar RF with temperature management; Thermage uses monopolar RF for skin tightening. Sharing the term radiofrequency does not make their effects or treatment amounts equivalent. Check whether there is actual fat that can appropriately be reduced, whether skin laxity is the main issue, and where volume should be preserved before comparing courses and quotes for the same area.
Separate fat-reduction and skin-tightening goals, then compare the full course
If localized subcutaneous fat under the chin is the main concern, discuss whether MiniFX is applicable; if the aim is mild skin laxity rather than fat reduction, discuss the actual Forma and Thermage plans. An indistinct jawline can result from excess skin, tissue descent, skeletal structure, muscle or swelling as well as fat, so a device cannot be assigned from photographs alone. If cheeks are already hollow, first mark areas to preserve and obtain an explanation of the limits of energy treatment for substantial excess skin or volume deficiency. Do not simply pit the price of 1 InMode session against 1 Thermage session. Break down quotes over the same period into initial treatment, proposed repeat sessions, possible additions after response assessment, maintenance and return-visit costs. The comparison period is a common basis for assessing outcomes, not an instruction to make retreatment intervals identical.
| Comparison criterion | MiniFX | Forma | Thermage FLX |
|---|---|---|---|
| Goal for this treatment | Actual localized fat and contouring goals, and suitable sites | Skin-laxity goals distinguished from fat reduction | Goals for the appearance of wrinkles, skin laxity and contour |
| Delivery method | Suction and bipolar RF; confirm the actual handpiece | Bipolar RF through contact electrodes and temperature management | Monopolar RF, treatment tip, return pad and cooling |
| Areas to preserve | Areas where fat reduction should be avoided, such as hollow cheeks | Thin skin, altered sensation and previously treated areas | Existing hollows, tip coverage and areas requiring caution |
| Treatment records | Record application time, passes and actual settings by area | Record time, passes and temperature management by area | Record tip type, actual treatment shots and distribution by area |
| Course and assessment | Proposed session count and intervals, and criteria for stopping or changing the plan | Distinguish initial repeat sessions from subsequent maintenance | Assess the first treatment’s results and whether more is needed |
| Total quote and recovery | Suction marks and bruising; full-course and return-visit costs | Heat and erythema; full-course and return-visit costs | Pain and swelling; costs including tip, treatment shots and assessment |
Definitions and how the treatments work
Bipolar RF passes current between neighboring electrodes; monopolar RF passes current between the treatment electrode and a return pad. Both use heat generated by tissue resistance. MiniFX’s combination of vacuum and bipolar RF differs from Forma’s contact and temperature control; Thermage’s tip, cooling and energy control also require separate consideration. Do not impose a simple ranking that bipolar is always shallow and monopolar always stronger. The Forma description on the manufacturer’s Define page and MiniFX description in its SEC report distinguish equipment; they are not head-to-head trials of cosmetic efficacy. Do not transfer outcomes from Morpheus8 RF microneedling or invasive FaceTite treatment to MiniFX or Forma here. Check country- and model-specific approvals and Korean instructions separately.
Potential benefits and limitations
If examination confirms suitability, the aim may be gradual changes in localized contour or the appearance of mild skin laxity and wrinkles. Do not treat Thermage as localized fat removal or calculate Forma as the same fat-reduction plan as MiniFX. The material reviewed does not compare all three methods directly under identical conditions or establish a universal winner or rankings for safety or durability. Do not mistake initial swelling or temporary tightness for the final result; assess with consistent lighting, angles and expressions and weight records. If you expect removal of substantial excess skin, surgical lifting or volume replacement, discuss other medical options as well.
Who can seek a consultation and how suitability is assessed
Adults concerned about facial fat or jawline laxity should first explain recent weight changes and cheek areas they want to preserve. Report fillers, threads, fat grafting, surgery and previous RF treatment, reduced sensation, wounds, infection, dermatitis, medications, bleeding risks, pregnancy and breastfeeding. Electronic implants such as pacemakers and implantable cardioverter-defibrillators are especially important; Thermage’s official safety information lists them as contraindications. Dental metal and other implants require separate assessment according to type, location and the device instructions. Do not automatically consider Thermage safe simply because the face is thin.
Procedure, recovery and scheduling
First document goals and excluded areas under the chin, along the jawline and on the cheeks during examination, and confirm the actual handpiece or tip, pain control and observation plan. Ask for separate quotes for the first treatment, the proposed initial course total, and optional additional costs after assessment. Check anesthesia, consumables, aftercare, taxes, follow-up, changes or cancellations for unused sessions, and whether overseas visitors can return. InMode minutes and Thermage shots are not the same quantity of energy; increasing time or shots cannot make effects equivalent. Do not compress repeat treatments into a short trip; agree on assessment after returning home. Heat, erythema and swelling may last hours to days; suction marks and bruising may last several days to 1–2 weeks or longer, so account for individual variation when planning photography and departure.
Side effects, contraindications and symptoms requiring medical attention
For MiniFX, discuss suction marks, bruising, tenderness, swelling and unwanted volume changes; for Forma and Thermage, discuss heat, erythema, swelling, pain and possible thermal injury. None has a 0 risk of burns, blisters, scarring, pigment changes, surface irregularities or altered sensation. Bruising or severe pain is not proof of efficacy. These materials cannot compare complication rates across the three methods, and Thermage cannot be promised to eliminate the risk of cheek hollowing. Immediately report intolerable localized heat or pain during treatment; seek examination for blisters, skin color changes, worsening pain, persistent tingling, muscle weakness or progressive hollowing.
Choose the goals you need and distinct treatment courses instead of a winning brand
| Category | Role and goals | What to check |
|---|---|---|
| MiniFX | Consider when there is an actual localized fat or contouring goal | Check suction, bipolar RF, areas where fat should be preserved and the proposed course |
| Forma | Consider skin-tightening goals separately from fat reduction | Treatment extent, temperature management and repeat-session plan for contact bipolar RF |
| Thermage FLX | Consider wrinkle and skin-laxity goals for monopolar RF | Tip, treatment shots, distribution, electronic-implant contraindications and follow-up assessment |
Questions and answers for a medical consultation
These questions for a consultation before visiting SEOLREIM are based on the literature. They are not a clinician interview or an individual prescription. This new article is awaiting confirmation of a separate review by a medical professional.
Q. Is MiniFX for faces with more fat and Thermage for those with less?
A. Treatment cannot be assigned automatically that way. Examine actual fat, swelling, muscles, skeletal structure and skin laxity, then first identify areas where fat can be reduced and those to preserve.
Q. Do several Forma sessions equal the treatment amount of one Thermage session?
A. There is no evidence for converting session counts, minutes and shots into one another. Ask about expected changes, recovery and total costs for the same target area and assessment period; judge the need for repeat treatment by the response.
Q. Can all three be booked at SEOLREIM?
A. Thermage FLX was confirmed on the official menu. Current ownership and availability of MiniFX and Forma require separate confirmation; this comparison article does not promise that they can be booked.
Consultation with the SEOLREIM clinic director and signature programs
SEOLREIM Clinic describes its principles of consultation and treatment directly by the physician, genuine products, correct quantities and attentive care; Thermage FLX and Oligio can be found on its official menu. For Thermage, confirm the genuine tip, actual treatment shots, area and follow-up assessment. MiniFX and Forma are comparison subjects and are not presented as confirmed current equipment or services. Benjamin Lifting is a separate thread-lifting program; do not use its name interchangeably with an InMode mode or RF course, and discuss it separately when there is a different treatment goal.
Booking, languages, location and guidance for international visitors
When comparing InMode and Thermage at a Gangnam dermatology clinic, distinguish the quote for 1 session from the full-course quote. Overseas clients seeking a Seoul dermatology clinic should organize weight changes and cheek areas they wish to preserve, and ask SEOLREIM about the feasible scope of follow-up when returning to a clinic near Gangnam Station or in Korea is difficult. The official international patient guide describes consultation support from on-site English- and Chinese-speaking staff and interpretation in 14 languages with advance booking; advance reservations are required before visiting. SEOLREIM Clinic is on floor 11 of Gangnam8258 Building, 376 Gangnam-daero, Seoul, approximately 1 minute from Exit 3 of Gangnam Station. Use the KakaoTalk, Naver booking and telephone channels below for Korean-language consultations and bookings, and the International consultation link for visits from overseas. Provide the treatment of interest, skin concerns, dates in Korea, preferred language and whether interpretation is needed. Confirm the actual scope of language support, costs, booking confirmation and cancellation terms before visiting. Depending on the examination, same-day treatment may be unavailable or follow-up after returning home may be needed; also discuss how to report adverse reactions and the actual scope of aftercare.
