Facial aging is more complex than simply the downward sagging of the skin. Over time, collagen and elastin levels decline, the supporting tissues gradually lose their elasticity, and changes occur in the distribution and volume of facial fat. Together, these structural changes can lead to a less defined jawline, more prominent jowls and a double chin, and an overall facial contour that appears heavier and less refined.

The face is composed of different anatomical structures, with variations in skin thickness, fat layer depth, and tissue characteristics across different areas. Therefore, applying the same level of energy throughout the face or relying on a single lifting technology may not adequately address the different aspects of facial aging.

KUDO UltheLiner is designed around these structural differences. By combining Ultherapy and Tune Liner, two ultrasound technologies with distinct mechanisms of action, this comprehensive lifting solution addresses skin elasticity, localized fat volume, and facial contours. In a previous KUDO Journal article, we introduced the characteristics of UltheLiner and the importance of combination lifting treatments. This article takes a closer look at how each ultrasound technology interacts with the skin and underlying fat tissue, and why combining different technologies can provide a more comprehensive approach to facial rejuvenation.

The Key to Ultrasound Lifting Lies in the Depth of Energy Delivery

Ultrasound lifting technologies deliver energy to specific depths beneath the skin while minimizing damage to the surface. However, not all ultrasound devices work in the same way. Some technologies focus ultrasound energy at precise points to stimulate tissue contraction and collagen remodeling, while others deliver energy to the subcutaneous fat layer to help reduce localized fat volume.

Understanding these differences is essential because facial aging involves more than a loss of skin elasticity. Even within the same face, skin thickness, fat volume, tissue elasticity, and the degree of sagging vary by area. Changes in fat distribution and volume also contribute to the gradual alteration of facial contours.

For example, when a less defined jawline is primarily caused by reduced elasticity in the skin and supporting tissues, a treatment that promotes tissue contraction and collagen remodeling may be appropriate. In contrast, when excess fat volume contributes to a double chin or prominent jowls, an approach targeting the subcutaneous fat layer may be more suitable. When both factors are present, combining technologies that act on different tissue structures can offer a more comprehensive treatment strategy.

KUDO UltheLiner addresses these structural differences by combining Ultherapy, which promotes skin tightening and collagen remodeling, with Tune Liner, which targets localized fat volume. Together, these technologies provide a comprehensive ultrasound lifting solution that approaches different tissue layers according to their individual characteristics.

Rather than simply tightening the skin or reducing facial fat, treatment planning begins with a detailed assessment of skin thickness, fat distribution, skeletal structure, and tissue elasticity. Based on these findings, treatment areas, energy levels, target depths, and the combination of technologies are carefully selected to refine unnecessary volume while improving areas that require greater firmness and support.

Ultimately, precision lifting is not defined by how much energy is delivered, but by accurately determining which technology should be applied to which tissue. The goal is to preserve each individual’s natural facial structure and balance while creating a more refined, harmonious contour.

Ultherapy | Microfocused Ultrasound for Deep Tissue Tightening

Ultherapy is a non-invasive lifting treatment that uses microfocused ultrasound technology to deliver concentrated energy to specific depths beneath the skin, including the deep dermis, subcutaneous tissue, and superficial musculoaponeurotic system (SMAS), while minimizing damage to the skin surface.

The focused ultrasound energy creates microscopic thermal coagulation points within the targeted tissues. This process may produce an immediate tissue contraction response, followed by a gradual wound-healing process that stimulates collagen remodeling and improves skin firmness over time.

One of Ultherapy’s key advantages is its ability to deliver energy at different depths. Transducers targeting 1.5 mm, 3.0 mm, and 4.5 mm are commonly used, with the appropriate depth selected according to skin thickness, anatomical structure, and treatment objectives. Ultherapy also incorporates real-time ultrasound imaging, allowing practitioners to visualize underlying tissue structures and determine the appropriate depth and location for energy delivery.

However, the SMAS layer is not located at the same depth in every individual, and tissue responses may vary depending on anatomical characteristics. For this reason, the effectiveness of Ultherapy depends not simply on the number of treatment lines delivered, but on a carefully designed treatment plan that determines the appropriate areas, depths, and energy levels for each facial structure.

Tune Liner | 3D Ultrasound Technology Targeting the Subcutaneous Fat Layer

While Ultherapy focuses on improving the elasticity of the skin and supporting tissues, Tune Liner is an ultrasound treatment designed to address localized fat volume that contributes to heavier or less defined facial contours.

Tune Liner utilizes 3D ultrasound technology to deliver energy to the subcutaneous fat layer. By generating controlled thermal effects within targeted fat tissue, the treatment may help reduce localized fat volume and create a slimmer, more refined facial contour.

This approach may be particularly suitable for individuals with a double chin caused by excess submental fat or prominent jowls associated with increased fat volume in the lower face.

However, reducing facial fat is not always beneficial. Facial fat is not simply excess tissue; it plays an essential role in maintaining facial volume, three-dimensional structure, and a youthful appearance. Excessive fat reduction, particularly beneath the cheekbones or in the central cheeks, may create a hollow appearance and accentuate visible signs of aging.

Therefore, Tune Liner should not be approached as a treatment for reducing fat throughout the entire face. Instead, its value lies in selectively addressing localized fat deposits that disrupt facial definition while preserving the volume necessary for natural facial balance.

KUDO’s Precision Combination Lifting Solution

Even when facial aging concerns appear similar, their underlying causes may differ depending on facial anatomy, fat distribution, and skin elasticity. The purpose of combining two ultrasound technologies is not simply to intensify treatment effects, but to provide a more precise and individualized approach to facial rejuvenation.

Through personalized one-on-one consultations and detailed facial assessments, the treatment areas, energy levels, and target depths of Ultherapy and Tune Liner are carefully determined. By refining unnecessary volume while improving skin firmness and tissue support, the goal is to achieve natural-looking lifting results that preserve each individual’s unique facial proportions and balance.

For concerns such as a sagging jawline, double chin, prominent jowls, or overall loss of skin elasticity, a personalized consultation at KUDO Dermatology can help determine the most appropriate lifting approach for your facial structure.
