This is a guide to Tuneliner compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
Many people notice a loss of elasticity and are bothered by a double chin when they look in the mirror. We've examined how Tuneliner, which uses 3D ultrasound to address fat cells, works to refine the face line.
Background of a double chin
When collagen and elastin decrease, elasticity drops, and the skin tends to sag downwards due to gravity.
- When muscles weaken, reducing the strength that supports the skin.
- When skin becomes dry, leading to a loss of elasticity.
- When fat accumulates under the chin and in the deep areas, changing one's impression.
How 3D ultrasound works
Tuneliner works by vibrating fat cells with 3D ultrasound to reduce them. It is used to intensively treat fat in bothersome areas like the double chin and deep jowls, helping to refine the face into a slimmer line.
A distinctive feature is that it selectively treats only the areas of concern, not the entire face.
Designed with surrounding tissues in mind
The 3D ultrasound is designed not to damage the areas around the fat to be removed and not to affect blood vessels and nerve tissues. This is the principle by which ultrasound selectively treats fat cells.
Expected changes
As energy is delivered, it also addresses cellulite and swelling, and stimulates collagen to improve elasticity.

Pain and recovery
The procedure is generally comfortable with a warm sensation, and the recovery period is relatively short, making it easier to return to daily life. However, recovery patterns may vary depending on individual skin conditions.
Why consultation comes first
It is important to carefully examine the face and then decide which areas to treat. It is also advisable to check during the procedure and adjust the approach to achieve the desired face line.
For double chin and deep jowls, an approach that selectively treats fat can be helpful. If your impression has changed due to increased fat, we recommend getting a diagnosis first.
