“After 35, the flesh on my face feels like it’s been yanked down by gravity – my jawline blurs, my cheekbones drop, and even though my weight hasn’t changed, my face looks noticeably wider.” This is the resigned realisation many women face in the mirror. The essence of facial ageing is “multi‑layer collapse” – fascial laxity, dermal collagen fragmentation, and fat pad descent. A single anti‑ageing modality can often only cover one layer, offering a temporary fix rather than a fundamental solution. The Korean Mifas Multi‑Dimensional Focused Thermoplasty System (Mifas Deep Lift) deeply couples High‑Intensity Focused Ultrasound (HIFU) with Monopolar Radiofrequency (RF) to create a “three‑dimensional thermal coagulation network” under the skin – tightening from the fascia to the superficial dermis simultaneously, restoring the “upward” support of facial contours – all without surgery and without downtime.
Thermage uses monopolar RF to heat the dermis from the surface inward – effectively tightening skin and improving fine lines – but it has limited effect on the SMAS fascia at 4.5mm depth, so its lifting power is insufficient. Ultherapy (HIFU), while precisely heating the fascia to create “spot‑like” contractions, lacks volumetric heating of the dermis, so it cannot simultaneously improve skin texture and fine lines.
Many patients try to cover all bases by doing Ultherapy first and then Thermage – not only doubling the cost but also enduring two sessions of pain and recovery. More critically, the energy timing of the two devices differs; if not properly coordinated, they may cause excessive tissue damage or insufficient overlapping effects. The ideal solution should be one device, one session, full‑layer coverage. Mifas Deep Anti‑Ageing was designed exactly for this.
Mifas is a next‑generation composite energy anti‑ageing device from Korea. It integrates High‑Intensity Focused Ultrasound (HIFU) and Monopolar Radiofrequency (RF) into a single treatment handpiece, using “dual‑energy coaxial” technology to simultaneously release both energies beneath the skin: HIFU for deep “spot‑anchoring” (4.5mm at the fascia), and RF for mid‑layer “volumetric heating” (2.0‑3.5mm in the dermis). Together, they form a “surface + spot” combined three‑dimensional thermal coagulation network.
The device features an intelligent temperature control system that monitors subcutaneous temperature in real time, ensuring the fascia reaches 60‑65°C (effective contraction temperature), the dermis is maintained at 43‑45°C (optimal collagen neogenesis temperature), and the epidermis is kept below 40°C through contact cooling. The treatment takes about 30‑40 minutes, requires no topical anaesthesia, and is felt only as a warm sensation with mild pressure (especially over bony areas). An immediate lifting effect of 20‑30% is visible right after treatment, which continues to improve over 3‑6 months, with results lasting 1.5‑2 years.
HIFU energy precisely targets the SMAS fascia (4.5mm depth), creating multiple thermal coagulation points about 1mm in diameter (65°C) that cause immediate fascial contraction – producing an “upward” lifting effect. At the same time, the thermal stimulus induces fibroblast migration to the area, continuously secreting new collagen over 3‑6 months post‑treatment – forming a “reinforcement layer” that enhances fascial resilience and long‑term support, effectively improving blurry jawlines, jowls, and drooping brows.
Monopolar RF creates a uniform thermal field at 2.0‑3.5mm depth (43‑45°C), activating the “heat‑shock protein” signal in dermal fibroblasts, prompting them to synthesise large amounts of type I and type III collagen and elastin. At 1‑3 months post‑treatment, skin thickness and elasticity increase, and fine lines, pores, and roughness are noticeably improved – skin texture becomes refined and translucent, providing a “cushion” of support for the fascial lifting effect.
RF energy at 3.0mm depth also acts on the subcutaneous fat layer – through gentle thermal action, fat cell volume shrinks and cells become more compact, effectively improving double chins, jawline fat deposits, and buccal “baby fat.” At the same time, the micro‑thermal coagulation points created by HIFU in the fat layer accelerate local fat metabolism, making facial contours sharper and more defined – revealing a more “structural” three‑dimensionality.
The handpiece is equipped with a multi‑point contact cooling system that instantly lowers skin temperature to 5‑10°C upon contact, ensuring the epidermis stays below 40°C throughout. The entire treatment involves only a warm sensation and mild pressure (especially over the cheekbones and jawline) – no topical anaesthesia needed – and you can apply makeup and resume normal activities immediately, truly achieving “pain‑free anti‑ageing.”
Natural feel: The lifting effect is “progressive” – facial contours tighten week by week, expressions remain natural without the “pulled” look.
Harmonious integration: Layered heating simultaneously tightens all layers – the transition from forehead to jawline is smooth, without local depressions or “stork‑bite” bulges.
Personalised precision: Three depth settings (2.0/3.0/4.5mm) can be freely combined – customised based on each individual’s skin thickness, fascial laxity, and fat distribution – achieving “one parameter per person.”
Long‑lasting durability: A single session can last 1.5‑2 years, and with annual consolidation sessions, results continue to accumulate – anti‑ageing no longer needs to be “redone every year.”

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, Mifas Deep Anti‑Ageing is priced by the number of shots and treatment area. A basic facial rejuvenation (about 250‑300 shots) costs approximately 800,000 – 1,200,000 KRW per session; full‑face to neck deep lifting (including jawline and double chin enhancement, about 350‑400 shots) is about 1,200,000 – 1,800,000 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 a “domino effect” – the fascia loosens first, then the dermis collapses, and the fat pads slide along with it. The significance of Mifas lies in using “composite energy” to hold up every domino simultaneously, helping them stand and reposition together. When the “anchor” of ultrasound and the “heat” of RF interweave beneath the skin, lifting and tightening are no longer compromises – they become a synergistic renewal from deep to superficial layers. What emerges is not just clearer contours, but the quiet confidence you feel when facing the mirror – no longer needing to avoid your own profile.
