What Are the Jawline Improvement Effects?

“Even with all the care I take, my double chin won’t go away.”

“Why is the fat under my chin still there even after losing weight?”

One area that is hard to lose even with dieting is the double chin.

When fat accumulates under the chin, the face can look overall dull, and even if the body is on the slimmer side, it can create the impression of weighing more than you actually do, which causes stress for many people.

In particular, if a double chin remains even after weight loss, it may be worth considering that the cause is not simply fat, but a loss of skin elasticity.

One procedure that can help improve a double chin caused by reduced elasticity is Ultherapy Prime.

Today, let’s take a closer look at how Ultherapy Prime helps define the jawline.

The Principles of Ulthera

Ulthera is a lifting procedure that uses high-intensity focused ultrasound (HIFU) energy to stimulate the SMAS layer, the deeper layer of the skin.

High-intensity focused ultrasound is, as the name suggests, a method that concentrates ultrasound energy into a single point to create strong energy.

This concentrated energy is delivered to the relatively deep fascial layer (SMAS layer), which plays an important role in determining facial contours.

When thermal stimulation is delivered to this area, loosened collagen contracts, and new collagen is produced during the skin’s recovery process.

As this process repeats, the jawline can become more defined, and a lifting effect that makes the face appear pulled upward can be expected.

Ulthera is also known as a device with a relatively long-lasting effect compared to other high-intensity focused ultrasound devices.

One reason for this is that the procedure can be performed while checking ultrasound imaging.

With other devices, treatment is often carried out without directly checking the inside of the skin, but Ulthera allows the practitioner to work while viewing the internal skin structure on an ultrasound screen.

This makes it possible to deliver the necessary number of shots to the exact location, reducing unnecessary energy waste and increasing the likelihood of effective lifting results.

However, conventional Ulthera had a limitation in that the depth at which the inside of the skin could be confirmed was up to about 4.5 mm.

In cases where the skin is thick, it could be difficult to accurately identify the fascial layer, and this was sometimes pointed out as a drawback because it could reduce treatment accuracy.

The device introduced to address these limitations is Ultherapy Prime.

Ultherapy Prime works on the same basic principle, but its ultrasound imaging system has been upgraded, which is its key feature for improving treatment accuracy.

It can confirm the skin structure down to a maximum depth of about 8 mm, and the screen size and resolution have also been improved, allowing the internal structure to be seen more clearly.

Thanks to this, more accurate treatment is possible, and as a result, some people say the effect feels more noticeable than with the original Ulthera, or that the lasting period feels longer.

What Procedures Are Good to Combine With It?

Ultherapy Prime uses three tips—1.5 mm, 3.0 mm, and 4.5 mm—to target different skin depths.

The 1.5 mm and 3.0 mm tips are mainly used to work on the skin surface and dermis to improve elasticity.

The 4.5 mm tip is used to stimulate the fascial layer and create facial contouring and lifting effects.

However, because high-intensity focused ultrasound devices deliver energy point by point, there are limits to how evenly heat can be delivered across the entire face.

In addition, it is a feature of the procedure that the effects take a certain amount of time to appear.

For this reason, it may feel somewhat insufficient if the main goals are immediate changes or improvements in pores or skin texture.

The procedure that is performed together to address these points is Trinity.

Trinity is a device that delivers heat energy from the superficial skin layer to the dermis by simultaneously or sequentially applying three different laser wavelengths: 755 nm, 808 nm, and 1064 nm.

Among these, 1064 nm acts on the fascial layer and, similar to Ulthera, helps make a blurred jawline appear more defined.

On the other hand, the 755 nm and 808 nm wavelengths act on the dermis and can help improve skin elasticity and pores.

Because Trinity delivers heat to multiple layers at once, one advantage is that results appear quickly.

Therefore, if you want both quicker changes in facial lines and improvement in pores, getting it together with Trinity is a good option.

Among Sinchon lifting procedures, Ulthera is a representative lifting procedure that delivers energy to the fascial layer, which influences facial contours, helping to clearly define the jawline.

Among them, Ultherapy Prime is distinguished by being a device that upgrades the ultrasound imaging function of the original Ulthera to improve treatment accuracy.

However, Ultherapy Prime alone may have limitations when it comes to improving overall skin condition, such as skin texture and pores, at the same time.

In such cases, using a laser device like Trinity together can allow you to expect both lifting and skin texture improvement at once, which may lead to more satisfying results.
