Even when double chins look the same, their causes can differ.
Ultherapy PRIME begins by examining the skin layers before treatment for this very reason.
When the area beneath the chin looks thick, it is easy to assume that the cause is weight gain.
However, accumulated fat and a fascial layer that has shifted downward may look similar on the surface, while requiring completely different approaches for improvement.
If volume is the issue, it needs to be reduced;
if sagging is the issue, the loosened layer needs to be lifted.
What is visible is only the result.
That is why the process of identifying which layer the problem began in must come first.

The beginning of lifting: Ultherapy PRIME
There is a separate layer that makes the area beneath the chin look heavy
It is not simply a matter of body weight. Even among thin people, the boundary can look indistinct from the side. In such cases, the layer that supports the skin has lost strength. Beneath the skin are the dermis, fat layer, and the fascial layer that surrounds the entire face, arranged in sequence. When this fascial layer becomes loose, the tissue above it flows downward and gathers beneath the chin.
As we age, this supporting network becomes looser. When this is combined with a posture in which we look down at a screen, the front of the neck folds, accelerating the sagging process. It is difficult to distinguish whether the cause is fat or sagging based on appearance alone, and it is also common for both conditions to overlap. If treatment begins without examining the layers, energy may be delivered to an unsuitable location.

An examination method that looks as deep as 8 mm
Ultherapy PRIME uses high-intensity focused ultrasound. When ultrasound is concentrated at a single point, heat is created only at that location. When this heat reaches the temperature at which collagen responds, the loosened tissue contracts and regeneration begins. It is a method in which changes occur internally without removing or peeling the surface. The key difference lies in the depth of observation.
While existing devices could examine down to 4.5 mm, PRIME can view depths of up to 8 mm. This makes it possible to determine which layer to treat even when the skin is thick or sagging has progressed.
A depth of 1.5 mm and 3.0 mm reaches the dermis, while 4.5 mm reaches the fascial layer. Another difference is that reduced screen noise makes the boundaries between layers appear more clearly. With shot speed increased by 20%, the time spent in one location is shorter even with the same 100 shots, which helps reduce the burden during treatment. If fat remains beneath the chin as well, a plan may combine 100 ultrasound shots to address the loosened layer with contouring injections to manage the volume.

Changes that first become visible from the side
Changes appear gradually. Immediately after treatment, there may only be a mild sensation of tightening. Because it takes time for new collagen to build up, the jawline gradually becomes more defined over the course of two to three months.
Many people notice the change first in side-profile photos. This is because the angle becomes more defined from the side than from the front. When the point where the neck and chin meet no longer folds, the overall impression looks more refined, and the areas that were bothersome when taking photos or lowering the head may also become less noticeable.
Recovery is generally relatively easy. Cleansing and makeup are possible on the day of treatment, and using a gentle cleanser is recommended. For three to seven days, while the heat settles, wash your face with lukewarm water. For about one week, avoid saunas, alcohol, and irritating peels. Redness or swelling may remain for several days depending on your individual condition, so a consultation beforehand is necessary.

A double chin is easy to see as a problem of excess fat. However, even when the appearance is the same, the appropriate approach differs depending on which layer has weakened. Beginning without an examination may therefore lead away from the desired direction. This is why Ultherapy PRIME emphasizes observation down to 8 mm. The outcome depends less on how much energy is used than on where it is delivered.
The number of shots comes next. If you feel that your jawline is beginning to lose definition, the time to identify the change and create a plan is the most important point.
