Hello,

This is Dr. Ahn Sung Hwan, Head Director of Gangnam Yonsei Line Clinic.

As time passes, there are moments when you suddenly look in the mirror and feel that your overall facial impression is no longer quite the same as before.

Even if your weight has stayed the same, the areas around the mouth and jawline may begin to look heavier, while facial contours become less defined, making the face appear wider.

At times like this, many people begin considering lifting treatments.

At the same time, however, realistic concerns often arise first:

“Will my facial expressions look unnatural if things are pulled too tightly?”
“Since my skin is thin, could my cheeks end up looking hollow?”

Because everyone has different skin thickness, facial structures, and lower-face contours, achieving satisfying refinement requires a precise approach tailored to your current condition.

Today, for those seeking a more natural-looking refinement, I’d like to talk about the process of facial contour management through Xerf.

“Why Does the Jawline Become Less Defined and the Lower Face Look Heavier?”

As we age, when the lower face begins to appear heavier or less defined, many people assume they have simply gained weight.

However, the underlying cause is often the weakening of the internal support structures that help maintain facial contour beneath the skin.

Tissues that were originally supported higher in the cheeks gradually lose structural support and shift downward with gravity.

As this happens, heaviness naturally accumulates around the mouth area and jawline.

This causes facial contour flow to become disrupted, making the overall silhouette appear wider and less refined.

Rather than forcefully pulling and fixing everything into place, the goal should be to gently reorganize facial lines that have shifted out of balance.

This approach allows you to restore the natural beauty and facial harmony that already belong to you.

“How Is Xerf Different from Other Lifting Approaches?”

Our skin is not made up of a single layer.

Instead, it consists of multiple interconnected layers, from the surface to deeper structures.

While many commonly known devices focus stimulation on only one layer, Xerf differs by utilizing two different radiofrequency energies simultaneously, allowing both superficial and deeper layers of the skin to be addressed at the same time.

Because both surface and deeper structures are refined together, energy can be distributed more precisely where it is needed.

At deeper levels, weakened structural support is reinforced to reduce heaviness in the lower face.

Closer to the surface, skin texture can appear smoother and more refined.

By distributing energy this way, Xerf aims to reduce unnecessary concentration of heat in one area while helping create a softer and more balanced facial contour overall.

“Who Tends to Be Most Satisfied with Xerf?”

The people we most often recommend Xerf to are:

Those with less facial volume or thinner skin who worry about unwanted side effects.

Some lifting devices rely heavily on strong tissue contraction.

For people with naturally little facial volume, this may sometimes create concern about losing fullness in areas where balance is important, making the cheeks appear more hollow.

On the other hand, Xerf does not work by forcibly reducing volume or dissolving fat.

Instead, it uses radiofrequency heat energy to support skin density and encourage facial lines to settle more naturally.

For this reason, it can feel like a reassuring alternative for individuals with thinner or more delicate skin who are concerned about facial hollowing.

“I’m Sensitive to Pain — How Much Discomfort Should I Expect?”

No matter how promising a treatment may sound, it is understandable to hesitate if the process feels too painful or overwhelming.

With lifting procedures, stronger stimulation does not automatically mean better results.

Xerf includes a cooling system designed to help keep the skin surface comfortable while energy is delivered.

As heat energy is directed into deeper layers, the system helps reduce discomfort at the surface while supporting skin protection throughout the process.

Because of this, individuals who are especially sensitive to discomfort or nervous about pain often find the experience more manageable than expected.

“Can I Return to Daily Life Right Away? Are There Any Precautions After Treatment?”

Busy professionals often hesitate because they worry swelling or visible marks may interfere with everyday life.

Since Xerf does not place excessive stress on the skin surface, many people find it manageable enough to return to makeup application, commuting, and daily activities relatively quickly.

However, because thermal reactions continue within the skin after treatment, it is recommended to follow a few precautions for about one week.

First

Avoid harsh exfoliating scrubs or intense facial massage techniques that may overly stimulate the skin.

Second

Activities involving excessive heat exposure — such as saunas, hot baths, steam rooms, or strenuous exercise that causes heavy sweating — are best moderated temporarily.

Third

To support skin stability and elasticity, it is helpful to be especially consistent with moisturizer and sunscreen application.

Please note: individual experiences, temporary reactions, and perceived changes may vary depending on skin characteristics and the degree of aging, which is why sufficient consultation beforehand is important.

Final Thoughts

Rather than endlessly searching through countless stories online, receiving an accurate evaluation of your current facial condition is often the fastest way to find the right direction.

No matter how sophisticated a device may be, subtle differences in results ultimately depend on how carefully the physician evaluates facial structure and designs the treatment approach.

Instead of chasing dramatic change, consider preserving the strengths your face already has while gently refining unnecessary heaviness and shadowing.

Sometimes, simply restoring balance is enough to naturally regain confidence when looking in the mirror.

We will always listen to your concerns with honesty and attention to detail.
