Every morning when you look in the mirror and see your jawline gradually blurring and a double chin quietly appearing, don’t you feel a sense of helplessness? With age, facial laxity, drooping cheeks, and deepening nasolabial folds are making more and more people turn to anti‑ageing treatments. But the US‑made Ultherapy, with its price tag of over a million KRW and the pain during treatment, puts many off. SHURINK was developed precisely to address this pain point – it is a widely used HIFU lifting device in Korea that uses high‑intensity focused ultrasound to precisely target the dermis and SMAS fascia, fundamentally improving laxity and sagging. More importantly, it is far more affordable than US‑made Ultherapy, with minimal downtime, and is hailed in the Korean aesthetic industry as a “high‑cost‑performance maintenance” treatment. But what exactly is the difference between SHURINK and Ultherapy? Is it painful? Are there side effects? Who is it suitable for? This article will comprehensively walk you through the principles, suitable candidates, treatment options and prices, procedure experience, duration of results, and potential risks – giving you all the key information in one place so you can make a rational choice.
SHURINK’s core technology is High‑Intensity Focused Ultrasound (HIFU). In simple terms, it’s like using a magnifying glass to focus sunlight – it precisely penetrates the skin surface and delivers ultrasound energy directly to the SMAS fascia (at a depth of about 4.5mm) below the subcutaneous fat layer, as well as the deep dermis (3.0mm) and superficial dermis (1.5mm).
When the energy is focused at these critical depths, it creates thermal coagulation points at 65°C to 75°C. This instant high‑temperature thermal effect causes the previously lax and inelastic fascia to contract immediately – much like shrinking meat on a grill. More importantly, over the following months, the body activates its natural wound‑healing mechanism, stimulating massive new production of collagen and elastin fibres, achieving a firming effect from the inside out.
SHURINK is equipped with three different depth probes (1.5mm, 3.0mm, and 4.5mm), targeting the superficial dermis, deep dermis, and SMAS fascia respectively. The therapist can choose different depth probes based on your skin condition and target areas for a “layered customisation” treatment – 1.5mm for pores and superficial fine lines, 3.0mm for stimulating dermal collagen regeneration, and 4.5mm for directly targeting the SMAS fascia – achieving comprehensive improvement from epidermis to fascia.
SHURINK is most suitable for those with moderate subcutaneous fat (e.g., jowls, double chin) and mild‑to‑moderate laxity. Specifically, it is ideal for the following groups:
However, not everyone is suitable. Conditions that are absolute contraindications or require careful evaluation include:
SHURINK treatment plans are mainly distinguished by shot count – the number of energy pulses delivered to the face. Different shot counts correspond to different coverage areas and intensity levels:
Below is a comparison of these options with reference prices (in KRW):
| Option | Best for | Features | Reference price (KRW) |
|---|---|---|---|
| 100 shots (localised) | Periorbital lines, nasolabial folds, first‑timers | Small coverage, suitable for local refinement, lowest price | ~70,000 – 110,000 |
| 300 shots (full‑face lifting) | Mild‑moderate laxity, blurry jawline, double chin | Best value, full‑face coverage, noticeable results | ~90,000 – 170,000 |
| 400 shots (face + neck) | Facial laxity + neck lines, neck laxity | Covers face and neck, comprehensive improvement | ~150,000 – 250,000 |
| 600 shots and above (full comprehensive) | Moderate‑severe laxity, seeking maximum results | Widest coverage, most long‑lasting results | ~200,000 – 350,000 |
Note: Prices above are reference ranges for the Korean market. Actual pricing varies by clinic and doctor qualification, and the Universe version is priced slightly higher than the traditional version – please refer to your in‑person consultation.
Your choice should be made after discussing your degree of laxity, treatment area, and budget with a dermatologist. For first‑timers, 300 shots is the most cost‑effective entry option.
Pre‑procedure preparation: On your first visit, the doctor conducts a consultation, assessing your facial laxity, fat thickness, and skin condition to determine the target areas and probe depths. A topical anaesthetic cream is applied for about 20‑30 minutes to enhance comfort.
During the procedure: The therapist selects the appropriate probe depth (1.5mm, 3.0mm, or 4.5mm) based on your skin concerns. The handpiece glides over the skin, delivering focused ultrasound energy precisely to the target layers. You may feel a mild warmth or a prickling sensation like needles. Full‑face treatment typically takes 20‑40 minutes, depending on the area and shot count.
Immediately after: Your skin may appear slightly red or warm, usually subsiding naturally within 2‑3 hours. SHURINK is a non‑invasive treatment with no wounds and extremely short downtime – you can resume daily activities immediately after treatment, without affecting normal social interactions.
SHURINK results unfold in three phases:
Immediate effect (right after treatment) – thermal stimulation causes immediate contraction of collagen and fascia, producing an instant tightening and mild lifting sensation. You may feel a slight tightness in the face immediately after the session.
Progressive effect (1‑3 months post‑treatment) – as collagen and elastin fibres continue to regenerate, the effect gradually intensifies. The true “peak effect” appears around 2‑3 months – by then, jawline definition becomes clearer, and double chin and nasolabial folds show significant improvement.
Stabilised effect (3‑6 months) – collagen regeneration peaks, and facial firmness and contour clarity stabilise. Results typically last 6‑12 months, depending on individual skin type, age, and post‑care.
SHURINK is generally recommended as annual maintenance. For those with more significant laxity, a second booster treatment at 6 months after the first session may be recommended.
Q: Is SHURINK painful?
A: Pain tolerance varies. Some users report “feeling warm and comfortable during treatment, with no particular discomfort,” while others say “it hurts a bit, like needle pricks.” However, compared to US‑made Ultherapy, SHURINK’s pain level is significantly lower. With topical anaesthetic applied beforehand, most people tolerate it easily.
Q: Are there side effects or long‑term risks?
A: As a non‑invasive treatment, SHURINK has very mild side effects. Common short‑term reactions includelocalised redness, mild swelling, and tenderness like muscle soreness when pressed– these usually subside within hours to days. However, risks to be aware of include:facial hollowing– if you already have severe cheek hollows or very little subcutaneous fat, blindly applying HIFU may cause fat atrophy, making the face appear more hollow;skin burns– may occur if the device is used improperly or if the equipment is substandard;nerve damage– extremely rare. Choosing a reputable clinic and a qualified doctor significantly reduces these risks.
Q: What’s the difference between SHURINK and Ulthera (Ultherapy)?
A: Both use HIFU technology, but the differences are clear:Price– SHURINK 300 shots costs ~90,000‑170,000 KRW, while US‑made Ultherapy costs several times more;Comfort– SHURINK is less painful;Results– Ultherapy delivers higher baseline energy with more noticeable single‑session tightening, but SHURINK’s advantage lies in its cost‑effectiveness and comfortable experience, making it ideal for routine maintenance.
Q: How soon can I wear makeup after SHURINK?
A: As a non‑invasive treatment, you can cleanse and apply makeup immediately after. However, use gentle cosmetics and avoid irritating ingredients. Pay attention to hydration and sun protection post‑treatment.
Q: What age group is SHURINK suitable for?
A: SHURINK is suitable forthose aged 25 and abovewith early signs of ageing, as well as30‑50 year oldswith mild‑to‑moderate facial laxity. For those over 50 with severe laxity, results may be limited – consult a doctor to assess whether combination with other anti‑ageing treatments is needed.
Important reminder: As a non‑invasive HIFU lifting treatment, SHURINK is relatively safe, but it is not “risk‑free.” Please make a rational decision after fully understanding the following information:
Core risks: Facial hollowing is the most concerning side effect – if you already have severe cheek hollows or very little subcutaneous fat, blindly applying HIFU may cause fat atrophy. Other risks include skin burns and nerve damage, often related to improper operation or use of counterfeit devices. SHURINK has not yet received CFDA (China NMPA) approval.
Post‑care essentials: Keep the skin hydrated and moisturised; always apply sunscreen when going out; avoid exposing the treated area to excessively hot or cold environments; treatment energy should start low and increase gradually – do not set it too high on the first session.
To minimise risks, be sure to: choose a licensed Korean dermatology or aesthetic clinic that uses genuine SHURINK equipment and original probes; have the procedure performed by a qualified doctor to ensure safety and results; fully disclose your skin condition to the doctor, especially whether you have cheek hollows or insufficient fat; be realistic about results – SHURINK provides a natural improvement in facial contours, not a dramatic transformation. It is more suitable as a high‑end maintenance treatment rather than a “time‑machine” miracle.
