Every morning when you look in the mirror, do you feel your jawline isn’t sharp enough? Does your double chin always sneak into photos? Or maybe you’re not overweight, but your face still looks puffy and “heavy”?
If any of this sounds familiar, you’ve probably seen InMode Diamond Sculpting popping up all over social media – it’s quietly become a hot topic in Korean dermatology clinics. Some call it a “body iron”, others say it’s a “savior for chubby faces” – but what exactly is it? And how does it differ from Thermage and Ultherapy? This article will clear everything up for you.
InMode Diamond Sculpting is a non‑invasive, non‑surgical radiofrequency device developed by InMode (Israel). In simple terms, it’s neither liposuction nor fat freezing – it’s a device that simultaneously achieves “fat reduction + skin tightening” using RF energy and high‑voltage pulse technology.
Its core technology combines Bipolar RF with High‑Voltage Pulsed (HVP) mechanisms. InMode Diamond Sculpting has two modes, each with a distinct role:
This mode specifically targets “excess fat”. During treatment, the applicator uses vacuum suction to “draw up” the skin and fat together, then delivers a first RF energy to uniformly heat the fat layer, followed instantly by a second nanosecond‑level ultra‑high‑voltage pulse that creates micro‑pores in fat cell membranes, inducing irreversible apoptosis of fat cells.
In simple terms: it makes fat cells “self‑destruct”, and they are then naturally metabolised by the lymphatic system. Clinical data shows that after a full course (about 3 sessions), local fat thickness can be reduced by an average of approximately 30%.
While the FX mode handles fat reduction, the FORMA mode is responsible for tightening and firming. It uses bipolar RF energy and patented A.C.E. temperature control technology to safely heat the dermis to between 41°C and 43°C, stimulating a significant increase in collagen and elastin fibres.
This mode does not destroy fat – it’s dedicated to improving skin laxity and fine lines. The treatment feels warm and comfortable, like a hot stone massage, and many people even fall asleep during the session.
This is the question everyone cares about most. To make it clear, I’ve put together this comparison table:
| Dimension | InMode Diamond Sculpting | Thermage | Ultherapy |
|---|---|---|---|
| Core Technology | Bipolar RF + High‑Voltage Pulse | Monopolar RF (Volumetric heating) | Micro‑focused Ultrasound (HIFU) |
| Target Layers | Fat layer + Dermis | Dermis | SMAS layer |
| Primary Function | Fat reduction + Tightening in one | Full‑layer tightening, skin texture improvement | Deep lifting, contour repositioning |
| Best for | Double chin, cheek fat, blurred jawline | Mild‑moderate laxity, fine lines, ageing skin | Moderate‑severe sagging, unclear jawline, tissue displacement |
| Treatment Sensation | Warm suction, high comfort | Deep heat, needs topical anaesthetic | Pointed prickling, needs topical anaesthetic |
| Duration of Results | ~6 months to 1 year | ~1‑1.5 years | ~2‑3 years |
| Price per session (KRW, reference) | ~350,000‑550,000 KRW | ~2,800,000 KRW (600 shots) | ~1,200,000 KRW (300 shots) |
| Downtime | Almost none; may have minor cupping marks that fade in 3‑5 days | Mild redness, 1‑3 days | Mild swelling, requires aftercare |
To summarise the differences in one sentence:
Facial concerns:
Body concerns:
Its core value lies in: simultaneous fat reduction and skin tightening – so when fat decreases, the skin doesn’t become loose, because the FORMA mode tightens it at the same time.
✅ Suitable candidates:
❌ Not suitable:
InMode Diamond Sculpting has virtually no downtime – you can resume normal life and work immediately. Many people do it during their lunch break and go straight back to the office.
However, it’s important to be honest: after the FX fat reduction mode, the treated area may show “cupping marks”. This is because the applicator uses strong suction to “draw up” the tissue and deliver energy precisely – it’s similar to cupping therapy. Those with sensitive skin may experience more noticeable marks.
These cupping marks usually fade within 3 to 5 days. A few people may have mild redness, swelling, or tenderness, which typically resolves within a few days. So if you have an important event coming up, plan to do the treatment at least a week in advance to allow enough buffer time.
Post‑treatment care is simple:
Result timeline:
InMode Diamond Sculpting has a very clear position – it sits between daily maintenance and medical body contouring, as a non‑invasive, localised sculpting device.
Quick selection guide:
In short, InMode Diamond Sculpting is like a body sculpting knife – precisely “shaving off” excess fat while simultaneously tightening the skin. For those with chubby faces, double chins, or unclear jawlines, its cost‑effectiveness and results make it well worth considering.
