As we age, collagen production in the skin decreases, which can easily lead to a loss of elasticity and a blurring of the facial contours. We've explored how ultrasound lifting addresses these changes, focusing on its operating principles.
Background of Decreased Elasticity
Collagen is a major protein that supports the skin and provides elasticity. As we age, reduced collagen production and slower cell regeneration can easily lead to sagging skin or wrinkles. External factors such as UV rays and stress can further accelerate this loss of elasticity.
Where Ultrasound Energy Acts
Ultrasound lifting delivers thermal energy to the SMAS layer, located deep within the skin. It works by creating thermal coagulation points to contract loose tissue, thereby inducing collagen production.
Because it targets deep layers rather than the surface, this approach aims for natural elasticity improvement along with changes in facial contours.
Cartridge Selection According to Depth
The cartridges used vary depending on the depth and condition of the skin layer. Energy is delivered to different depths, from the upper dermis to the SMAS layer. Therefore, it is important to diagnose the individual's skin thickness and condition before setting the treatment parameters.
- Shallow depth cartridges for shallow layers
- Deep depth cartridges for deep SMAS layer
- Output and number of shots adjusted for each area
Treatable Areas
It can be used not only for the jawline but also for areas where sagging is a concern, such as the cheeks, cheekbones, around the eyes, and around the mouth. Since it is a non-incisional method, returning to daily life is relatively easy, but recovery patterns and results may vary among individuals.

Modes and Customized Application
In addition to the normal mode, some devices offer additional modes, allowing for adjustments to the application method considering each individual's skin condition and area. Even with the same lifting treatment, the approach differs depending on which depth and what kind of energy is delivered.
Why the Practitioner's Diagnosis is Important
Even with good equipment, desired changes can only be expected if the skin condition is accurately diagnosed and appropriate energy levels and number of shots are set. Therefore, choosing a clinic that provides thorough consultation and diagnosis is key.
Ultrasound lifting is based on the principle of inducing a collagen response in the deep layers. If you are starting to be concerned about decreased elasticity, we recommend starting by getting your current skin condition diagnosed and determining the appropriate depth and number of shots for you.
