Dermal Filler vs. Thread Lift: Which Non-Surgical Facial Contouring Treatment Is Better for a More Defined Jawline and Facial Shape?
Gangnam HERA Clinic
When the face starts to look flatter, the cheeks lose some of their fullness, or the jawline becomes less defined, many people find themselves deciding between two popular non-surgical options: dermal fillers and thread lifting.
Both treatments can help improve facial contour, definition, and overall balance, but they work in very different ways. Fillers are mainly used to restore lost volume and enhance facial shape, while thread lifts are designed to support and reposition sagging soft tissue.
Understanding whether your main concern is volume loss, facial sagging, or a combination of both is the first step in deciding which treatment may be more suitable for your face.Although both dermal fillers and thread lifting can help improve facial shape without surgery, they work through very different mechanisms.
Fillers are mainly used to restore lost volume and enhance facial dimension, while thread lifts are designed to support and reposition sagging soft tissue.
So the key question is not “Which treatment is better?” but rather: “Is my facial concern mainly caused by volume loss, or by sagging and tissue descent?”
Understanding the real cause first can help determine whether dermal filler, thread lifting, or a combination of both is more appropriate for achieving a more defined, balanced, and natural-looking facial contour.
Determine Whether Your Main Concern Is…Your Face Has…Facial Concern Facial Volume Loss or Sagging? Which Is More Noticeable: Volume Loss or Sagging?
Before choosing between dermal filler and thread lifting, it is important to first identify the actual cause of your facial concern.
Ask whether your face is mainly experiencing “volume loss”, “sagging”, or a combination of both. A sunken or flatter appearance may be related to facial volume loss, while a heavier lower face or less defined jawline may be more associated with soft-tissue descent and skin laxity.
Understanding which problem is more dominant can help determine whether filler, thread lifting, or a combined non-surgical facial contouring approach is more appropriate for your face.
- Sunken Face — Facial Volume Loss
Facial volume loss can occur as fat compartments and underlying bone structure change with age, causing areas such as the temples and cheeks to look hollow or sunken and making the face appear flatter or less dimensional.
In these cases, treatment generally focuses on restoring facial volume and structural support in the areas that have lost fullness. Depending on the individual anatomy, options such as dermal filler, facial volume restoration, or other non-surgical facial contouring treatments may be considered to help rebuild facial dimension and balance.
- Sagging Face — Soft-Tissue Descent
Facial sagging occurs when the skin and underlying soft tissues gradually lose support and descend over time, making the cheeks appear lower, nasolabial folds more pronounced, and the jawline less smooth or defined.
In these cases, treatment generally focuses on lifting and supporting the descended tissues rather than simply adding more volume. Depending on the degree of skin laxity, tissue sagging, and facial anatomy, options such as thread lifting, facial lifting, or other non-surgical skin-tightening treatments may be considered to help restore a more defined and balanced facial contour.Even so, treatment should not be reduced to a simple formula such as “sunken face = add filler” or “undefined jawline = thread lift.” The face is made up of multiple interconnected layers, including bone structure, fat compartments, soft tissue, ligaments, muscle activity, and skin support, all of which influence facial shape and aging together.
This is why a well-planned non-surgical facial contouring treatment should look at the face as a whole rather than correcting only the most visible area. The doctor should assess whether the main issue is facial volume loss, tissue sagging, skin laxity, structural imbalance, or a combination of several factors before deciding between dermal filler, thread lifting, or a combined treatment approach.
A comprehensive facial assessment helps create a more personalized plan that supports natural-looking facial balance, better jawline definition, and more harmonious facial proportions.
3 Key Factors to Consider Before Choosing an Aesthetic Treatment

The face is made up of much more than the outer skin we can see. Its shape, contour, and three-dimensional appearance are created by the interaction of multiple deeper anatomical layers, including the facial bones, fat compartments, muscles, ligaments, soft tissues, and skin-supporting structures.
As we age, these layers gradually change together. Bone structure may lose support, facial fat may shift or decrease, soft tissues can descend, and skin elasticity may weaken, all of which can affect facial volume, definition, and overall balance.
This is why planning non-surgical facial contouring treatments such as dermal filler or thread lifting should begin with a comprehensive assessment of the deeper facial anatomy and age-related structural changes, rather than focusing only on the visible surface of the skin.Before deciding whether dermal filler should be used to restore lost volume or thread lifting should be used to support and reposition sagging tissue, the doctor should first perform a detailed facial assessment.
This evaluation helps determine whether the main concern is related to facial volume loss, tissue sagging, skin laxity, or structural changes, and whether one treatment or a combination approach may be more appropriate.
The assessment should focus on three key factors:1. Facial Bone Structure
The facial skeleton forms the foundation that determines the width, length, projection, and overall three-dimensional shape of the face. As we age, gradual bone remodeling and age-related bone resorption can occur in areas such as the temples, cheekbones, and jawline, reducing structural support for the overlying soft tissues.
These changes can contribute to facial volume loss, reduced contour definition, tissue descent, and a less supported appearance. This is why evaluating the underlying facial bone structure is important before deciding whether dermal filler, thread lifting, or another non-surgical facial contouring treatment is appropriate.2. Facial Volume and Fat Compartments
Facial fat is distributed across multiple deep and superficial fat compartments, which help create fullness, support facial contours, and maintain a more youthful appearance.
As these fat compartments gradually lose volume or shift with age, certain areas can begin to look hollow, sunken, or less defined. Common changes may include temple hollowness, flatter cheeks, under-eye hollows, and deeper facial folds.
Evaluating facial volume loss and fat distribution is therefore essential before choosing between dermal filler, thread lifting, or other non-surgical facial contouring treatments, because volume loss and tissue sagging require different approaches.3. Soft-Tissue Position and Retaining Ligaments
The soft tissues and retaining ligaments of the face help hold the skin and deeper facial layers in their proper position. As collagen, elasticity, and tissue support decrease with age, these structures may gradually weaken, allowing the soft tissues to descend.
When facial tissues shift away from their original position, they can contribute to more visible nasolabial folds, marionette lines, jowls, and reduced jawline definition.
This is why evaluating soft-tissue descent, ligament support, skin laxity, and facial sagging is important before choosing between dermal filler and thread lifting. Filler primarily addresses volume loss, while thread lifting is designed to help support and reposition sagging tissue, depending on the patient’s facial anatomy and degree of laxity.A well-designed treatment plan should evaluate the entire face as a connected structure, rather than treating each visible concern as an isolated point that simply needs to be filled or lifted.
By assessing the relationship between facial bone structure, fat compartments, soft-tissue position, retaining ligaments, volume loss, and sagging, the doctor can determine which areas truly need volume restoration, tissue support, lifting, or no treatment at all.
This comprehensive approach helps create a more personalized non-surgical facial contouring plan, whether using dermal filler, thread lifting, or a combination of both, with the goal of achieving more balanced, natural-looking facial proportions.
How Do Dermal Fillers and Thread Lifting Work Differently?

At Gangnam HERA Clinic, dermal fillers and thread lifting are used for clearly different purposes. The doctor first evaluates the client’s facial structure, volume loss, soft-tissue position, degree of sagging, and overall facial balance before deciding which treatment is more appropriate.
Depending on the individual assessment, dermal filler may be used to restore lost volume and refine facial contours, while thread lifting may be used to support and reposition sagging tissue. In some cases, the two treatments may be combined as part of a personalized non-surgical facial contouring plan when both volume loss and tissue descent need to be addressed.1. Dermal Filler
Dermal filler is used to restore lost facial volume and improve facial proportions by adding dimension and structural support where needed.
At Gangnam HERA Clinic, the approach is not to overfill the face or create excessive volume. Instead, filler treatment is designed to complement the person’s existing facial structure, proportions, and natural contours.
The goal is to achieve balanced, refined, and natural-looking facial contouring by placing the right amount of filler in the right areas, while preserving the patient’s original facial characteristics.2. Thread Lifting (Thread Lift)
Thread lifting is more suitable when the main concern is soft-tissue sagging or tissue descent rather than volume loss. The lifting threads act as a supportive framework beneath the skin, helping reposition and support descended facial tissues.
This can help improve jawline definition, lower-face contour, jowls, and facial sagging, creating a more lifted and structured appearance without traditional facelift surgery. The goal is to restore support and redefine the lower face while maintaining a natural-looking and balanced facial contour.In simple terms:
Volume Loss / Sunken Face → Consider Dermal Filler
Tissue Descent / Facial Sagging → Consider Thread Lifting
Both Volume Loss and Sagging → Consider a Combined Treatment Plan with Dermal Filler and Thread Lifting
If I Need Both Dermal Filler and Thread Lifting, Can They Be Done Together?
In some cases, the doctor may recommend combining dermal filler and thread lifting because each treatment addresses a different layer of the problem.
Dermal filler is used mainly for volume restoration and structural support, while thread lifting focuses on repositioning and supporting sagging soft tissue. When both facial volume loss and tissue descent are present, a carefully planned combination approach may help create a more balanced and natural-looking facial contour.At Gangnam HERA Clinic, a combination treatment approach may be considered when both lifting and volume restoration are needed. Depending on the doctor’s assessment, thread lifting and dermal filler can be planned together within the same overall treatment program when there is an appropriate indication.
This approach allows the doctor to address soft-tissue sagging and facial volume loss at the same time, while carefully considering the individual’s facial anatomy, tissue condition, treatment areas, and overall facial balance. The goal is to create a more personalized and coordinated non-surgical facial contouring plan while prioritizing safety and natural-looking results.However, “can be combined” does not mean that everyone needs both treatments at the same time.
The decision should depend on the individual facial condition and treatment goals. If the main concern is only volume loss, dermal filler alone may be enough. If the problem is mainly tissue sagging, thread lifting may be more appropriate. A combination plan should be considered only when both concerns are present and the doctor determines that using both treatments would provide a more balanced and suitable result.The doctor needs to carefully evaluate the treatment area, type of lifting thread, amount of dermal filler, and treatment sequence before combining procedures.
If too much filler is added to a face that already has significant soft-tissue sagging, the face may appear heavier, wider, or overfilled. Likewise, performing a thread lift without considering the client’s original facial proportions and tissue position may create an unnatural contour or disrupt overall facial balance.
This is why a personalized filler and thread lift treatment plan should be based on the individual’s facial anatomy, volume distribution, degree of sagging, existing proportions, and desired results. The goal is to restore support and definition without making the face look larger, distorted, or over-treated.The key principle is to use each aesthetic treatment only where it is truly necessary and allow each procedure to perform the role it is designed for.
Dermal filler should be used to restore volume where volume is lacking, while thread lifting should be used to support and reposition sagging tissue where lifting is actually needed. This targeted approach helps avoid unnecessary treatment and supports more balanced, natural-looking, and efficient facial contouring results.
Dr. Kim Jong Seon: Facial Contouring That Begins with Structural Analysis

Choosing between dermal filler and thread lifting can be more complex than it appears in the mirror. Concerns such as deep folds, a flatter facial appearance, loss of facial dimension, or a less defined jawline may be influenced by several underlying factors at the same time.
These can include facial bone structure, fat compartments, soft-tissue position, retaining ligaments, volume loss, and age-related changes in facial anatomy. Because these structures are interconnected, the visible problem may not always come from the area where it appears.
This is why a detailed facial structural analysis is important before deciding whether the face needs volume restoration with dermal filler, tissue support with thread lifting, or a combination of both. The goal is to identify the true cause first and create a more precise, balanced, and natural-looking non-surgical facial contouring plan.At Gangnam HERA Clinic, Dr. Kim Jong Seon applies his strong foundation in facial anatomy and aesthetic facial surgery to personalized facial contouring and rejuvenation treatments.
His key areas of focus include Advanced Filler techniques, thread lifting, non-surgical facial contouring, facial volume restoration, and combination treatments using dermal filler together with lifting threads.
By evaluating the relationship between facial bone structure, fat compartments, soft-tissue position, volume loss, and tissue sagging, Dr. Kim can determine whether the face would benefit more from filler, thread lifting, or a customized combination of both treatments to improve facial dimension, jawline definition, and overall facial balance.Dr. Kim Jong Seon’s approach is not to simply “fill every hollow” or “lift every sagging area.” Instead, he first evaluates how the different facial structures are related to one another and determines whether the visible concern is primarily caused by volume loss, soft-tissue descent, or a combination of both.
Based on this structural analysis, treatments such as Advanced Filler, thread lifting, or a combination of filler and lifting threads are used only where they are genuinely needed.
The goal is to create a face that looks more balanced, dimensional, and well defined, while preserving the individual’s original facial characteristics and achieving a natural-looking non-surgical facial contouring result.

FAQ: Frequently Asked Questions About Dermal Filler and Thread Lifting
Q. If My Jawline Is Not Well Defined, Do I Always Need a Thread Lift?Not necessarily. A less-defined jawline can be related to several factors, including facial volume loss, soft-tissue descent, skin laxity, and overall facial proportions.
Before deciding on a thread lift, the doctor should first identify the main cause of the contour change. Depending on the assessment, the most appropriate option may be thread lifting, dermal filler, facial contouring, or a combination treatment plan tailored to the individual face.Q. Can Adding More Dermal Filler Replace a Thread Lift?
Not directly. Dermal filler and thread lifting serve different purposes. Filler is mainly used to restore facial volume and refine shape, while thread lifting is designed to support and reposition sagging soft tissue.
Adding more filler does not create the same lifting effect as a thread lift and may not be appropriate when the main concern is facial sagging, tissue descent, or loss of jawline definition. The treatment choice should therefore be based on whether the primary issue is volume loss, sagging, or a combination of both.Q. If I’ve Had Dermal Filler or a Thread Lift Before, How Long Should I Wait Before Having Another Treatment?
The appropriate timing depends on several factors, including the type of previous procedure, treatment area, filler product or thread type used, and your current facial condition.
Because of this, it is important to share your previous aesthetic treatment history with the doctor before planning another procedure. The doctor can then assess whether additional dermal filler, thread lifting, or another facial contouring treatment is appropriate and when it can be performed safely.
Rather than relying on a general waiting period, the timing should be based on an individual evaluation of your facial anatomy, previous treatment materials, tissue condition, and current treatment needs.
If the face looks sunken, flat, or lacking in dimension, dermal filler may be one of the options the doctor considers for restoring volume and improving facial contours.
However, if the main concern is soft-tissue sagging, tissue descent, or a jawline that has become less defined, thread lifting may play a greater role in supporting and repositioning the tissues.
The most appropriate choice depends on whether the primary issue is facial volume loss, sagging, or a combination of both, which is why a detailed facial assessment should come before choosing the procedure.If both facial volume loss and sagging are present, it does not always mean you have to choose only one treatment.
In some cases, the doctor may recommend combining dermal filler for volume restoration with thread lifting for tissue support and repositioning. The key is to carefully balance both techniques and use only what is truly necessary for the individual face.
A well-planned combination treatment should aim to restore facial dimension and improve jawline definition while maintaining natural facial proportions, balance, and a refined, natural-looking result.If you would like to receive personalized facial care from an experienced Korean aesthetic doctor or plastic surgeon, you can send your current photos, main facial concerns, and previous aesthetic treatment history to STMStyle.
