This is a guide to Tune Liner compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
It's easy to think that a double chin is simply caused by weight gain, but in many cases, it's actually a sign of aging where skin elasticity decreases and the skin sags. Many people are concerned because it's not easily improved by exercise or diet alone. Let's summarize the causes of a double chin and the working principle of Tune Liner.
Two Causes of a Double Chin
- Fat: When fat accumulates under the chin, making it appear thick.
- Sagging: When collagen is damaged, leading to a loss of elasticity and the skin drooping downwards.
It is reported that a double chin caused by sagging cannot be resolved by simply removing fat.
Why Dieting Doesn't Always Work
If a double chin is caused by sagging rather than fat, there are limitations to addressing it with diet. An uneven jawline is difficult to hide with hairstyles and can easily become an aesthetic complex. Even when trying to cover it with contouring makeup, it can be unnatural or smudge, causing inconvenience.
Consult us to find out if your double chin is due to fat or sagging.
Tune Liner's Approach
Unlike general contour management that reduces the size of fat cells, Tune Liner works directly on the fat cells themselves. 3D volumetric ultrasound acts on fat cells while minimizing stress on skin, blood vessels, and nerve tissues.
| Category | General Contour Management | Tune Liner |
|---|---|---|
| Action | Reduces fat cell size | Targets fat cells themselves |
| Method | Single | Longitudinal wave + Transverse wave volumetric ultrasound |
| Duration | Relatively short | Relatively long |
It is characterized by using both the thermal energy of longitudinal waves and the physical energy of transverse waves to improve cellulite and promote a slimmer line.
Who Might Consider This Treatment
- Those concerned about both jowl fat and a double chin.
- Those whose face shape appears uneven or wide.
- Those with thin skin who found laser treatments burdensome.
Since Tune Liner utilizes ultrasound, the results can vary depending on the experience of the practitioner, so thorough consultation and diagnosis are important. It is designed to be less irritating to surrounding tissues and generally causes less pain, but the perceived sensation and results may vary individually. The relatively quick return to daily life immediately after the treatment is also a factor to consider.
