3 Reasons Why Shurink is Effective for Jowl Sagging



If you feel that the middle part of your face is sagging downwards, making your overall facial contour collapse, the cause is likely due to submental fat (jowls).



Shurink's approach to jowl sagging is different from simple surface lifting. It's a method that delivers energy deep into the skin layers, addressing the root cause of sagging.







Why Does Jowl Sagging Occur?



The main reason for sagging cheeks is the weakening of the supporting structures directly beneath the skin.



The face has a fibro-muscular structure called the SMAS layer (Superficial Musculoaponeurotic System). This layer connects and supports the skin and muscles, but as we age, its elasticity decreases, and fat pads move downwards due to gravity, causing the cheeks to start sagging.



Jowls are fat pads located deep beneath the cheekbones. Unlike superficial fat, their deep location makes it difficult for them to return to their original position once they start sagging, even with massage or skincare.







Reasons Why HIFU is Suitable for Jowl Sagging



Shurink uses the HIFU (High-Intensity Focused Ultrasound) method. The principle is to focus ultrasound energy at a specific depth, rather than on the skin's surface, selectively stimulating only that target layer.



Ultrasound passes through the skin's surface and forms thermal coagulation points (Thermal Coagulation Point) only at the target depth. When these thermal points reach the SMAS layer, collagen immediately contracts, followed by a regeneration process where new collagen is produced over several months.



Because it directly acts on the deeper layers without stimulating the surface, it can target the jowl area, which is difficult to reach with external care.







3 Reasons Why Shurink is Effective for Jowl Sagging



Reason 1. Directly Reaches the SMAS Layer



Shurink's 4.5mm tip focuses energy up to the depth of the SMAS layer. The lifting effect begins only when energy reaches this depth.



If the cause of jowl sagging is SMAS layer weakening and fat pad migration, then a 4.5mm tip approach that directly stimulates this layer is the most logical method. Treatments that only affect the surface cannot reverse sagging originating from deeper layers.







Reason 2. Collagen Contraction and Regeneration Occur Simultaneously



The moment HIFU energy reaches the SMAS layer, collagen fibers contract, resulting in an immediate tightening effect. This is the change felt right after the procedure.



Concurrently, a biological response to repair damaged tissues is activated. In this process, new collagen is generated, leading to a gradual increase in elasticity over 1 to 3 months post-procedure.



Because immediate and delayed effects work together, Shurink typically shows more distinct results one or two months after the procedure than immediately afterwards.







Reason 3. Adjustable Tip Depth for Targeted Jowl Treatment



Shurink's tip types vary in the depth of energy penetration. The 4.5mm, 3.0mm, 2.0mm, and 1.5mm tips each target different layers.



For jowl sagging, the 4.5mm tip stimulates the SMAS layer, and the 3.0mm tip additionally covers the deeper dermis layer above it. The ability to vary depth for different areas is a fundamental difference from superficial lifting.







Session and Cycle Guide



Shurink treatments are typically done monthly. It's a concept of cumulative treatments, not a one-time procedure, where collagen density and elasticity become firmer with each accumulated session.



The timing of the next treatment may be adjusted depending on the number of shots administered in a single session. If the area has been strongly stimulated, it's important to ensure sufficient recovery time before the next treatment.







Kkeut Korean Medicine Clinic's Unique Shurink Jowl Sagging Approach



At Kkeut Korean Medicine Clinic, we always perform the design phase in a seated position before lifting procedures. When lying down, the cheek fat shifts backward, making it difficult to accurately identify the true position of sagging cheeks. By designing in a seated position, we accurately confirm the sagging areas under real gravitational conditions and design the target range to avoid areas where cheek hollowing might occur.



We do not use only the 4.5mm tip. At Kkeut Korean Medicine Clinic, we use 3.0mm, 2.0mm, and 1.5mm tips together to achieve a multi-layered approach, from the layer where jowls are located up to the dermis. Even for the same area, building energy three-dimensionally layer by layer helps maintain the sagging improvement effect longer.



After the procedure, treatment details are recorded and shared on a lifting card. This record includes which mm tip was used, on which area, and how many shots were delivered, allowing for cumulative planning on subsequent visits by continuing from previous records.







Frequently Asked Questions



Q. From which session can I expect to feel the improvement in jowl sagging with Shurink?


A. Shurink jowl treatment has an immediate contraction effect, so some may notice changes from the same day. However, the full lifting effect due to collagen regeneration becomes apparent within 1 to 3 months. The effects accumulate more significantly with 2 to 3 cumulative sessions.



Q. What is the downtime after Shurink jowl treatment?


A. Shurink's approach to jowls does not damage the skin surface, so there is almost no downtime. There might be slight swelling or warmth immediately after the procedure, but it usually subsides within the same day, allowing for a return to daily activities the next day.



Q. How should the treatment cycle be set?


A. A 1-month cycle is standard. However, if a session was performed with high power and strong stimulation, it is advisable to allow sufficient recovery before scheduling the next treatment. Kkeut Korean Medicine Clinic manages cumulative treatment history per session via a lifting card, so cycle planning is data-driven.



Q. What is the difference between Shurink's approach to jowl sagging and InMode FX's approach?


A. Shurink for jowls is a method that directly stimulates the SMAS layer with HIFU ultrasound for lifting, while InMode FX uses RF thermal energy and high-voltage pulses to destroy fat cells. The approach differs depending on whether the cause of sagging cheeks is excessive fat volume or loss of elasticity/sagging. It is important to accurately identify the cause through consultation before deciding on a treatment.







Kkeut Korean Medicine Clinic's Sincerity



Kkeut Korean Medicine Clinic accurately identifies sagging areas under the actual conditions where gravity applies through seated design, implementing safe targeting without cheek hollowing.



Kkeut Korean Medicine Clinic uses custom tips of 3.0mm, 2.0mm, and 1.5mm in addition to the 4.5mm tip, building multi-layered energy three-dimensionally from the deep cheek fat layer to the dermal layer.



Kkeut Korean Medicine Clinic creates and shares a lifting card after each treatment, operating a cumulative treatment system where precision increases with each successive session.
