Many people hesitate about lifting procedures while thinking, "I've heard it's very painful." The pain-reducing effect of Cool Sonic is not just a marketing phrase, but originates from the cooling mechanism inherent in the equipment design. However, the degree of felt effect may vary depending on individual skin thickness and fat layer distribution, so professional medical diagnosis before treatment is essential first.
Considering Cool Sonic in Nonhyeon — "Less painful" has a mechanism behind it
When people think about lifting procedures, the first thing most come to mind is pain. Since accounts of "HIFU is too painful" are widely spread, many people find it difficult to make a reservation even though they know it's effective. However, there is an actual mechanism behind why Cool Sonic is known as "less painful."
According to eToday reporting, Cool Sonic is a cooling ultrasound lifting device developed by Asterasis and obtained domestic regulatory approval from the MFDS in February 2025. The key is the structure where the handpiece tip immediately cools the skin surface while delivering ultrasonic energy. It utilizes the neurophysiological principle where the cooling sensation on the skin surface stimulates the nerve pathway before pain signals, and related clinical data show that this approach contributes to reducing perceived pain during treatment.
In Newsis materials, the cooling function is also introduced as a key differentiator of Cool Sonic, and it can be confirmed that lower pain burden compared to existing HIFU is a result reflected from the equipment design stage.
However, this point must be clarified. The thicker the skin or fat layer, or if sagging has progressed considerably, it may be difficult to expect sufficient results from Cool Sonic alone, and it is a more practical approach to review with a specialist whether to combine with other procedures. Treatment suitability is determined after consultation.
The Core Structure That Differentiates Cool Sonic from Existing HIFU — Why Cooling Was Added
What is Cool Sonic?
Cool Sonic is a device with a dual structure that induces lifting effects by forming coagulation points in deep skin layers with focused ultrasound (HIFU) energy while simultaneously maintaining the skin surface at low temperature through the handpiece tip. Simply put, it works in a "hot inside, cool outside" manner.
According to related clinical data, ACC™ (Active Conductivity Cooling) technology lowers epidermal temperature, and TDT™ (Thermal Diffusion Therapy) technology precisely delivers ultrasonic energy to three levels of depth (1.5mm, 3.0mm, 4.5mm) including the SMAS layer. The structure suppresses pain sensation on the epidermis through cooling while properly delivering the energy needed for lifting to deep skin layers.
Pinpoint News reporting introduces that Cool Sonic's micro-cooling structure becomes a design-based foundation enabling higher energy output compared to existing HIFU. In other words, cooling is not simply an auxiliary function to reduce pain, but is designed as a prerequisite for safely delivering higher energy.
As confirmed in eToday, Asterasis obtained domestic MFDS product approval in February 2025, and it can be applied to the entire face including cheek sagging, double chin, jawline, eye area, forehead, and neck. In related clinical data, it is also known that the short downtime—where same-day cleansing and makeup are possible after treatment—becomes a practical advantage for those prioritizing same-day return to daily life.
Mini Q&A
-
Q. Is the lifting principle itself the same between HIFU and Cool Sonic?
The basic principle of creating coagulation points in deep layers through focused ultrasound is the same. The difference with Cool Sonic lies in adding a dual structure that actively cools the skin surface during that process. -
Q. Doesn't cooling affect the results?
Cooling is concentrated on the epidermis (shallow layer), and the lifting energy is delivered to the designed depth, so the structure is known not to interfere with the results themselves.
How Beutiful story clinic Operates Cool Sonic
Cool Sonic is good equipment, but the quality of results varies depending on how the practitioner approaches the procedure, even with the same device. To properly harness equipment performance, a process of accurately understanding individual skin condition before treatment must come first.
Beutiful story clinic's Cool Sonic Treatment Procedure
• Step 1 — Skin and Fat Layer Condition Diagnosis: At Beutiful story clinic, within a 1-hour single-patient concentrated appointment system, Chief Director Seo Bit-na, a plastic surgery specialist, directly diagnoses skin and fat layer condition before Cool Sonic treatment from a plastic surgery perspective and designs a treatment plan. After comprehensively understanding sagging angle, skin thickness, and fat layer distribution, a decision is made on whether to use Cool Sonic alone or combined procedures.
• Step 2 — Customized Treatment Plan Design: A multi-faceted approach applying both plastic surgery and dermatology perspectives, with probe depths (1.5, 3.0, 4.5mm) and energy levels individually designed for each area. Unnecessary treatments are not recommended, and a realistic plan matching the individual's condition and circumstances is presented.
• Step 3 — Pain Monitoring During Treatment: During treatment, patient response is confirmed in real-time and treatment speed and energy are adjusted. Unlike factory-style medical practice, this becomes possible in an environment focused on caring for one patient at a time.
• Step 4 — Post-Treatment Aftercare: Patent-pending pain and swelling minimization aftercare technology is applied to systematically manage the recovery process from immediately after treatment.
• Step 5 — Identical Fees Applied Domestically and Internationally: Identical fees are applied regardless of patient nationality, with honest medical practice without pressure to decide as a principle.
Is Cool Sonic the Right Choice for My Skin Condition or Not
Based on related clinical data, cases where Cool Sonic can be a practical option and cases where other methods should be considered first have been organized. This is only a reference standard, and accurate judgment must be made through specialist diagnosis.
Category | Applicable Condition |
|---|---|
✔ Cases where Cool Sonic may be appropriate | Those sensitive to pain who found existing HIFU burdensome |
Office workers and those with tight schedules requiring same-day daily return without downtime | |
Those concerned about minor sagging in facial line, jawline, and double chin | |
Those whose main concern is elasticity loss in eye area, forehead, and neck | |
✖ Cases where other procedures should be considered first | Cases of severe sagging and considerably thick fat layer |
Cases with metal implants in the treatment area | |
Cases with severe skin conditions (inflammatory acne, skin infection, etc.) in active state | |
Pregnancy or nursing status |
According to related clinical data, cases with considerable sagging progression or thick fat layer may achieve better results with methods other than Cool Sonic alone or combined procedures. Regardless of which procedure, checking whether it is suitable for your skin condition first, rather than "because it's trendy," is the most important.

Most Frequently Asked Questions by Nonhyeon and Gangnam Patients Before Receiving Cool Sonic
Q1. Can I receive Cool Sonic without numbing cream?
Cool Sonic is designed with cooling technology to reduce pain burden, so some patients receive treatment without numbing cream. However, pain sensitivity varies individually and can differ depending on treatment area or energy level. If you mention your pain sensitivity in advance during consultation, the approach can be adjusted accordingly.
Q2. How long does the effect last after receiving Cool Sonic once?
Effects appear gradually between 1-3 months as collagen regeneration progresses, rather than immediately after treatment, and the maintenance period varies depending on skin condition and lifestyle habits. Generally, many consider re-treatment on a 6-month to 1-year cycle, but determining the cycle after confirming individual skin condition is more accurate.
Q3. I have considerable sagging—would Cool Sonic be appropriate for me, or would another procedure be better?
In cases of considerable sagging or thick fat layer, methods other than Cool Sonic alone such as other HIFU methods or thread lifting and combined procedures may yield more effective results. Cool Sonic has strengths in improving minor sagging and restoring elasticity, but may have limitations with severe sagging, requiring prior diagnosis. Treatment suitability is determined after consultation.
