“Every time the season changes, my face hits the ‘down’ button – my jawline blurs, cheekbones drop, and nasolabial folds become deep enough to catch foundation.” This is a seasonal worry for many women over 30. Traditional Thermage or Ultherapy can tighten skin, but they usually only cover 2‑3 depths – for multi‑layer laxity involving the fascia, dermis, and fat layers, they often “miss the mark.” The Korean 7D Layered Focused Thermage System, with its next‑generation “multi‑depth focused RF” technology, can freely switch between seven depths – 1.5mm, 2.5mm, 3.5mm, 4.5mm, 6.0mm, 8.0mm, and 10.0mm – achieving “three‑dimensional anchoring” from the epidermis to the fascia, turning a sagging face into a lifted one with just one non‑invasive treatment.
Facial ageing is “three‑dimensional” – the epidermis thins, dermal collagen is lost, fat pads descend, and the fascia loosens – each layer sagging at a different rate and to a different degree. Traditional Thermage usually has only 3‑4 depth settings, making it difficult to simultaneously achieve “deep SMAS anchoring” and “superficial dermal tightening.” If you only treat the deep layers, superficial laxity remains; if you only treat the superficial layers, the deep fascia still “can’t hold.”
More commonly, many devices lack precise energy focusing – the heating zone is too broad, causing “thermal diffusion” – the deep layers don’t get enough heat while the superficial layers overheat. Not only does this compromise results, but it may also damage the epidermis or nerves. 7D Thermage uses “multi‑point focused, depth‑adjustable” technology to precisely deliver thermal energy to each layer that needs tightening – making “each layer tightens itself” a reality.
7D Thermage is a new‑generation multi‑depth focused radiofrequency (RF) skin‑tightening system. Using “phased‑array focusing technology” and “intelligent impedance sensing,” it allows free selection of seven different treatment depths within the subcutaneous range of 1.5mm to 10.0mm, in 0.5mm increments. Each depth corresponds to a different tissue layer: 1.5mm (epidermal basal layer), 2.5mm (superficial dermis), 3.5mm (deep dermis), 4.5mm (SMAS fascia), 6.0mm (superficial fat), 8.0mm (deep fat), and 10.0mm (supraperiosteal fascia).
During treatment, the doctor customises a “multi‑depth combination” based on each individual’s skin thickness, fat distribution, and degree of sagging – for example, using 4.5mm (fascial anchoring) + 3.5mm (dermal tightening) for the jawline, 6.0mm (fat reduction) + 4.5mm (fascial tightening) for a double chin, and 1.5mm (epidermal renewal) + 2.5mm (dermal support) for the periorbital area. One session covers all layers that need improvement – no need for multiple sessions. The entire treatment takes about 40‑60 minutes, is non‑invasive with no downtime, and shows immediate contour improvement, with results peaking at 3‑6 months.
The 4.5mm depth targets the SMAS fascia, and the 10.0mm depth targets the supraperiosteal fascia – together forming the “deep load‑bearing system” of the face. Thermal energy (about 60‑65°C) causes immediate contraction of fascial fibres, generating an “upward” lifting force that fundamentally improves blurry jawlines, marionette lines, and drooping brows. At the same time, the thermal stimulus induces fibroblast migration and proliferation, continuously strengthening fascial resilience over 3‑6 months post‑treatment, ensuring long‑term stability of the lifting effect.
The 2.5mm and 3.5mm depths correspond to the superficial and deep dermis – the “main production zones” for collagen and elastin. Thermal energy (about 43‑45°C) activates the “heat‑shock protein” signal in fibroblasts, prompting them to synthesise large amounts of type I and type III collagen. At 1‑3 months post‑treatment, skin thickness increases, elasticity improves, and fine lines, pores, and roughness are noticeably reduced – skin texture becomes refined and translucent, providing a “cushion” of support for the fascial lifting effect.
The 6.0mm and 8.0mm depths target the superficial and deep subcutaneous fat layers. Thermal action reduces fat cell volume and compacts their arrangement, effectively improving double chins, jawline fat deposits, and buccal “baby fat.” At the same time, thermal stimulation accelerates local fat metabolism, making facial contours sharper and more defined – revealing a more “structural” three‑dimensionality. This is especially beneficial for those with “full faces” and prominent double chins.
The 1.5mm depth targets the epidermal basal layer – gentle heating promotes corneocyte turnover and synthesis of natural moisturising factors (NMF). Immediately after treatment, the skin becomes more hydrated and radiant, and subsequent skincare absorption is significantly enhanced. This layer ensures that the overall result is not just “tight” and “lifted,” but also “bright” and “hydrated” – achieving “from‑within‑out” rejuvenation.
Natural feel: The effect is a “layer‑by‑layer tightening” integration – the face is not “pulled tight” but “lifted up,” expressions remain natural, and movement is fluid.
Harmonious integration: The seven depths can be freely combined based on individual differences, ensuring each layer receives the “just‑right” thermal stimulus – the overall contour is harmonious and unified.
Personalised precision: Based on each person’s facial anatomy and ageing pattern, a “depth combination plan” is customised – one parameter set per person, no “one‑size‑fits‑all” template.
Long‑lasting durability: A single session can last 1.5‑2 years, and because multiple depths work in synergy, the decline is gradual rather than abrupt.

Those with pacemakers, defibrillators, or other electronic implants, pregnant women, minors, and those with gold threads in the treatment area are not recommended for this treatment.
💰 Cost Reference
In Korea, 7D Thermage is priced by depth combination and number of shots. A basic facial rejuvenation (3‑4 depth combination, about 200‑250 shots) costs approximately 700,000 – 1,100,000 KRW per session; full‑face to neck deep lifting (including double chin and jawline enhancement, 5‑7 depth combination, about 300‑350 shots) is about 1,100,000 – 1,700,000 KRW; premium custom plans (including periorbital or perioral enhancement) are around 1,600,000 – 2,300,000 KRW. A single session is usually sufficient for satisfactory results, with an optional booster at 1‑2 months. The above includes treatment fees and basic aftercare, but excludes repair masks or oral supplements.
🕒 Recovery Timeline
Day of treatment: Mild redness and warmth, with a firm sensation – subsides within 1‑2 hours. Normal cleansing and makeup are fine; avoid heavy makeup, alcohol, and saunas for 24 hours, and drink plenty of water to promote metabolism.
Days 1‑3: Some areas may feel slight pressure or achiness – a normal thermal response. Normal social activities can resume; focus on hydration and sun protection.
Weeks 1‑4: Collagen neogenesis begins – skin firmness and elasticity continuously improve, fine lines soften, and the jawline gradually becomes clearer. This is the “accumulation phase” – results become visible day by day.
Months 1‑3: Results peak – facial contours are lifted and firm, skin texture is refined and translucent, and overall youthfulness is significantly enhanced. A follow‑up at 3 months is recommended to evaluate results and plan annual maintenance.
Months 6‑24: Results remain stable – an annual maintenance session is recommended to keep the anti‑ageing effects accumulating and slow the natural ageing process.
Facial ageing is not a “single sheet of paper” but a “seven‑storey tower” – each layer has its own rhythm and trajectory. The wisdom of 7D Thermage lies in using seven depths to precisely respond to the ageing signals of seven layers – giving each layer a “tailor‑made” thermal stimulus. When the deep fascia is anchored, the mid‑layer dermis is activated, and the superficial epidermis is renewed, the face is no longer a collection of “individual layers going their own way,” but a unified whole that “grows upward” together. You don’t need to remember the name of each layer – just look in the mirror and see that face with clear contours and radiant glow – that is the answer 7D gives you.
