A detailed look at the differences between Xerf and Thermage for laser lifting in Gangnam, Seoul

"If your face line looks blurrier than before"

When your jawline is not clearly defined in photos,

or your cheeks feel as if they have dropped downward, you may start taking an interest in skin-firming procedures.

If changing cosmetics or trying massage does not make much difference to your facial line,

it is natural to turn your attention to radiofrequency lifting.

When you search for skin-firming procedures in Gangnam, Seoul,

Xerf and Thermage are often compared.

They share the commonality of delivering monopolar radiofrequency energy to the skin, inducing a thermal response and managing elasticity and skin texture through collagen remodeling.

However, they differ in the frequencies used and in the structure that controls thermal energy.

Today, we’ll look at the differences between Xerf and Thermage in Gangnam, Seoul,

and explore what criteria to consider when choosing a procedure.

"Why does your facial line change every day?"

Changes in facial contours cannot be explained by skin sagging alone.

As we age, collagen and elastic fibers in the dermis decrease,

and the skin thickness, fat distribution, and facial support structure also change.

A face with thin, dry skin may first show fine lines and reduced elasticity.

On the other hand, a face with more fat around the cheeks and jaw

may appear to have a heavier lower face, making the jawline look less defined.

A face with hollowness under the cheekbones or at the sides of the cheeks may also show more pronounced indentations if strong contouring is performed.

This is why even people in the same age group can have different areas of concern and different tissue conditions.

When choosing a skin-firming procedure, do not just check the device’s reputation

or the number of shots; you should also consider skin thickness, fat volume, facial contours,

and the changes you want to achieve.

"Xerf and Thermage, with different energy structures"

Thermage delivers 6.78MHz monopolar radiofrequency to the skin

and generates heat in the dermis and subcutaneous tissue.

Thermage FLX uses AccuREP technology, which measures skin resistance with each pulse,

and protects the skin surface during treatment through vibration and a cooling system.

It can be applied when managing overall facial elasticity loss, fine wrinkles, and skin texture together.

Xerf also uses monopolar radiofrequency, but it differs in that it combines two frequencies, 6.78MHz and 2MHz.

With three depth modes—Shallow, Middle, and Deep—and adjustable energy levels,

the range of heat diffusion can be designed according to skin thickness and area.

It also allows skin resistance measurement through real-time impedance feedback,

customized energy adjustment, and minimization of pain and irritation.

The key difference between Xerf and Thermage in Gangnam, Seoul is not whether they use radiofrequency,

but how the frequencies are configured and how the energy is adjusted.

Rather than dividing them by which device is stronger, the plan should center on how thermal energy is delivered to match the condition of the facial tissue.

"Look at the condition of the face before the device"

1) When the cheeks are full and the lower face appears noticeably heavy

2) When the skin is thin and the sides of the cheeks look hollow

It is difficult to approach both with the same treatment.

For the former, focus on jawline and cheek-area elasticity,

and for the latter, energy and treatment areas must be carefully adjusted

so that facial dimensionality is not reduced too much.

At GU Clinic Gangnam Main Branch,

we check skin thickness, fat distribution, the direction of sagging, and facial balance

before determining the treatment area and intensity.

If you are deciding between Xerf and Thermage,

rather than choosing the device name first,

it is better to start by selecting a clinician who can build a plan

suited to the changes you want to improve.

The difference in radiofrequency lifting

is determined by the actual treatment design and direction applied to the face.

Finding the exact depth and range needed for your face

is the first step toward satisfying elasticity care.
