The Secret Behind Actress Son Ye-jin's Firm Skin: ULTLINE

Key Features

  • 5th-Generation High-Intensity Focused Ultrasound (HIFU)
  • Targeted Lifting for the Face and Body
  • Customized Lifting for Different Skin Layers

ULTLINE

Hello,
I’m Dr. Ki-beom Park,

Medical Director of GU Clinic Gangnam.

When the facial contours begin to look softer or the cheeks

and jawline feel less firm than before,

many people start searching for HIFU lifting treatments.

HIFU lifting delivers focused ultrasound energy to targeted

depths beneath the skin without making incisions.

Even among ultrasound lifting devices, the available treatment depths,

delivery methods, and tissue visualization features can differ.

In this article, we will explain the principles and differences between ULTLINE and Ultherapy PRIME,

along with the points to consider when choosing an ultrasound lifting treatment in Gangnam, Seoul.


"How Does HIFU Lifting Work?"

HIFU lifting concentrates ultrasound energy at specific depths beneath

the skin to create thermal coagulation points.

By delivering energy to the targeted tissue layer,

it induces tissue contraction and supports collagen remodeling.

The face consists of several layers, including the skin, subcutaneous fat,

and the superficial musculoaponeurotic system.

Thin-skinned areas such as the forehead and around the eyes

may require different treatment depths from thicker areas such as the jawline.

"Son Ye-jin Lifting:

How Does ULTLINE Work?"

ULTLINE in Gangnam, Seoul uses multiple cartridges designed to deliver

ultrasound energy to various tissue depths across the face and body.

For facial treatments, energy can be distributed according to the area of concern,

from layers close to the skin’s surface to the dermal and superficial musculoaponeurotic layers.

ULTLINE can also deliver energy in either dot or line modes. Narrow areas can be treated in greater detail,

while energy can be distributed at regular intervals across wider areas.

Separate cartridges are available for the face and body,

allowing the device to be used for facial contours as well as areas

such as the abdomen, arms, and thighs.

Ultherapy Prime

Key Features

  • Real-time skin visualization is possible with 3D ultrasound imaging
  • More even energy delivery with a wider handpiece
  • More precise energy distribution technology

An upgraded version of the existing Ultherapy that precisely delivers energy to the SMAS layer, helping contract sagging tissue and restore skin elasticity.

"How Is Ultherapy PRIME Different?"

Ultherapy PRIME is a focused ultrasound lifting device

that delivers energy while allowing the practitioner to

visualize the tissue beneath the skin.

Its DeepSEE™ ultrasound imaging technology provides real-time visualization of

the skin, fat, and superficial musculoaponeurotic layers.

The practitioner uses the tissue depth and condition shown on the screen to determine

the appropriate cartridge and treatment position.

Energy can then be delivered according to the area of concern,

from the superficial skin layers to the dermis and deeper supportive tissue.

However, the imaging feature does not mean that the same cartridge or

number of treatment lines is used for every face.

The treatment range should be planned after assessing skin thickness,

fat distribution, and the location of tissue laxity.

"ULTLINE vs Ultherapy PRIME:

What Are the Differences?"

Neither device can be considered the better choice for every person.

A thin face with fine lines and early loss of elasticity requires

a different treatment depth and delivery method from a face with

fuller cheeks and noticeable heaviness in the lower face.

Even when treating the entire face, the forehead, eye area, front cheeks,

side cheeks, and jawline may require different depths and energy settings.

Applying excessive energy to areas with little facial fat or targeting

a layer unrelated to the cause of laxity may result in changes that fall short of expectations.


"Your Facial Anatomy Should Come

Before the Device Name"

When searching for HIFU lifting in Gangnam, it is easy to compare

the device, price, or number of treatment lines first.

However, even with the same device, the treatment plan may vary depending on skin thickness,

facial fat, the location where laxity begins, and previous lifting treatments.

At GU Clinic Gangnam, we assess the skin, fat, and deeper supportive structures

before selecting between ULTLINE and Ultherapy PRIME and planning

the cartridge depth and treatment range.

If you want more defined facial contours and firmer-looking skin,

begin with a detailed consultation to identify the lifting approach suited to your facial anatomy.
