Author: Nurse Fuku
Job Title: Nurse

As we age, these issues become more noticeable: sagging along the jawline, loose cheeks, shadows around the mouth, and a double chin.

There are various treatments for sagging skin in cosmetic medicine, but

"What's the difference between a hyphen and a pneumon?"
"If I'm also concerned about fat, which treatment is best for me?"
"I want to undergo treatment while minimizing downtime."
"I want to improve both sagging skin and enlarged pores at the same time."

I imagine many of you are unsure about which treatment to choose.

In this article, we’ll discuss one of the most popular treatments for sagging skin offered at BIANCA CLINIC,Hyph, Pneuma Prime X, and Mofius 8 BurstI will explain their characteristics and differences in an easy-to-understand way from a nurse's perspective.

What You'll Learn in This Article

• Differences Between Hyphe, Pneuma, Prime X, and Mofius 8

• The types of sagging each treatment is best suited for

• Differences in Approaches to Fat, Sagging Skin, and Skin Texture

• Pain and Downtime Trends

• How to Choose a Treatment That Fits Your Needs

• Reasons for Combining Multiple Treatments

Conclusion | The four treatments differ in “how heat is delivered and at what depth”

To summarize the four treatments briefly, they are as follows:

treatment	Primary Energy Source	Key Features	Issues This Is Suited For
half-open (e.g. door, window)	High-Intensity Focused Ultrasound	Heating the deep layers in small, localized areas	Deep-seated sagging, loss of facial contour definition
volnema	Monopolar RF	Heat the fat layer in a continuous band from the dermis	Sagging skin, loss of firmness
Prime X	Ultrasound + RF	Comprehensive Care for Fat and Skin	Double chin, sagging caused by fat
Mofius 8 burst	Microneedles + RF	Delivering RF energy at multiple depths from the needle tip	Sagging, enlarged pores, uneven skin texture, acne scars

It’s not a matter of which treatment is the best.

The most suitable procedure varies depending on the layer causing sagging, body fat, skin thickness, bone structure, your desired results, and the amount of downtime you can tolerate.

To begin with, why does the face sag?

Facial sagging isn't simply caused by the skin stretching.

The main factors are as follows.

• Decrease in collagen and elastin

• Loss of skin elasticity

• Changes in the Amount and Location of Subcutaneous Fat

• Loosening of the tissue that supports fat

• Changes in supporting tissues such as fascia and ligaments

• Age-Related Changes in Skeletal Structure and Bone Mass

• A sagging facial contour caused by swelling or fat

Because these factors often overlap, you may not notice significant changes even if you focus solely on caring for the skin's surface.

In current treatments for sagging skin,Which layer—such as the epidermis, dermis, subcutaneous fat, or fascia—should receive what type of energy?It is important to consider these factors when choosing a treatment.

1. Hyfu | For those who want to tighten their skin from deep within

Hyph is

HIFU is an abbreviation for "High-Intensity Focused Ultrasound," which is known in Japanese as "high-density focused ultrasound."

This treatment focuses ultrasound energy on a single point to deliver heat to a specified depth while minimizing stress on the skin's surface.

At BIANCA CLINIC, we offer medical HIFU devicesUltraCell ZiWe have implemented it.

UltraCell Zi uses different cartridges depending on the treatment area and objective, targeting areas ranging from the superficial layers of the skin to the subcutaneous tissue and the area near the SMAS layer.

Features of Hyph

A key feature of Hyfu is its ability to deliver heat in small, localized spots deep within the tissue.

In the dot mode, which is the primary mode of operation, heat is concentrated at the targeted depth to achieve skin tightening by utilizing tissue contraction and the subsequent healing process.

In addition, the UltraCell Zi features a "Linear Mode" that delivers heat over a wide area, allowing you to choose the irradiation method that best suits your needs.

Who Is a Good Candidate for Hyuf?

• I'm concerned about sagging along my jawline

• I want to firm up my cheeks and the area under my chin

• I want to achieve a lifting effect from deep within the skin

• I want to undergo a treatment for sagging skin without surgery

• We want to minimize downtime as much as possible.

Hyuf's Downtime and Risks

After the treatment, you may experience a sensation of heat, redness, swelling, tenderness, or itching.

Although most cases are temporary, in rare instances, swelling, numbness, loss of sensation, a burning sensation, or nerve damage may occur.

For individuals with low body fat or those prone to sunken cheeks, the treatment area and energy level must be carefully determined.

2. Volnuuma | RF Treatment That Tightens Loose Skin Across the Entire Face

What is Borneuma?

Borneuma is a non-invasive skin tightening treatment that uses a 6.78 MHz monopolar RF.

RF stands for "Radio Frequency," which is referred to in Japanese as "high-frequency waves" or "radio waves."

While protecting the skin's surface, it delivers heat over a wide area from the dermis to the fat layer, aiming to tighten the skin and improve its firmness.

The Difference Between Hyphes and Pneuma

The main difference between Hyph and Volnuma lies in the type of energy used and how heat is delivered.

HIFU focuses ultrasound waves on a single point, delivering heat in a pinpoint manner to deep layers.

On the other hand, Volnuma uses RF to heat the fat layer beneath the dermis in a three-dimensional and extensive manner.

To give you an idea,

• Hyfu: Targets deep tissue with focused spots

• Borneuma: Tightens the subcutaneous fat layer across the entire surface of the skin

There is a difference between the two.

It’s not a matter of one being better than the other; since the layers responsible for sagging are different, we may use both treatments together depending on the condition.

Who Should Use Volnuma?

• I'm concerned about sagging in my cheeks and around my mouth

• I want to naturally firm up my entire skin

• I'm concerned about facial line leanness.

• I also want to improve my skin's firmness and elasticity

• I want to avoid severe pain and a long recovery period

• Undergoing a cosmetic procedure for sagging skin for the first time

Downtime and Risks Associated with Volnuma

After the procedure, you may experience a sensation of heat, redness, swelling, or tenderness.

In most cases, symptoms subside within a few hours to a few days, but in rare cases, bruising, burns, blisters, numbness, loss of sensation, or reactivation of herpes simplex may occur.

3. Prime X | Simultaneously addresses fat and sagging skin

What is Prime X?

Prime X is a non-invasive facial and body contouring device that combines ultrasound and high-frequency RF.

We use different applicators depending on the condition of the face and body to target fat, tighten the skin, and improve firmness.

This is a good option for people who feel that “not only is their skin sagging, but the fat is also making their jawline look heavy.”

Prime X's Main Approach

At BIANCA CLINIC, we combine the following applicators depending on the treatment goal.

Speed Sculpting

It uses ultrasound to target localized fat under the chin and on the face.

Uni-Large

It delivers RF energy to relatively deep layers of the skin, helping to strengthen the skin's foundation and promote collagen production.

Tune Face

It delivers RF energy to relatively shallow layers of the skin to help tighten the skin and improve its firmness.

By combining multiple treatments based on the condition of your face, we target both fat and skin.

Who Should Consider Prime X

• I'm concerned about my double chin

• Fat makes the jawline look blurry

• I want to make my cheeks and the area under my chin look less heavy and more defined.

• I want to tighten my skin and contour my face at the same time

• I would like to receive treatment that does not involve injections or needles.

• I'm concerned not only about my face but also about sagging in certain parts of my body.

Prime X Downtime Risks

After the treatment, you may experience redness, a sensation of heat, stinging, pain, swelling, irritation, or dryness.

Redness and a sensation of heat caused by ultrasound tend to subside relatively quickly, but redness caused by RF may last from a few days to about a week.

In rare cases, severe pain, burns, tinnitus, and other symptoms may occur.

4. Mofius 8 Burst | Simultaneously Treats Sagging and Skin Texture

What is Mophius 8 Burst?

Morpheus 8 Burst is a treatment that combines microneedles and RF.

A thin needle is inserted into the skin, and RF energy is delivered through the needle tip, allowing heat to be delivered directly to the inner layers of the skin while minimizing excessive heat exposure to the skin's surface.

At BIANCA CLINIC, we have evolved from the previous Mofius 8 toMofius 8 burstWe have implemented it.

A key feature of the burst function is its ability to continuously deliver RF energy to multiple depths with a single pulse.

Features of the Mofius 8 Burst

With the Mofius 8 Burst, depending on the needle depth and output settings, it provides a three-dimensional treatment of the dermis, subcutaneous tissue, and subcutaneous fat.

In addition to the thermal effects of RF, this treatment utilizes the wound-healing response triggered by needle insertion to support the production of collagen and elastin.

Therefore, it is ideal for those who want to address not only sagging but also other skin concerns such as enlarged pores, acne scars, uneven skin texture, and fine lines all at the same time.

Who Should Consider the Mofius 8 Burst?

• I'm concerned about sagging skin and a lack of firmness

• I want to really tighten my jawline

• I’d also like to treat my pores and acne scars at the same time

• I want to even out my skin's texture and tone

• I want to actively pursue treatment, even if it means taking time off work.

• I didn't feel that conventional treatments for sagging skin produced significant results

Downtime and Risks of the Mofius 8 Burst

Because it involves the use of needles, it tends to result in more downtime than Hyuf, Volnuma, and Prime X.

After the procedure, you may experience redness, swelling, puffiness, pinpoint bleeding, bruising, pain, dryness, roughness, or needle marks.

In addition, there is a risk of burns, hyperpigmentation, infection, nerve damage, and skin irregularities.

Since you may need to refrain from washing your face or applying makeup on the day of your treatment, we recommend scheduling your appointment with plenty of time to spare if you have important plans.

By Concern | Which Sagging Treatment Should You Choose?

I want to firm up my jawline from deep within.

half-open (e.g. door, window)will be an option.

Heat is delivered to deep layers, including the SMAS layer, to tighten the skin from the foundation of the face.

I'm concerned about sagging skin on my cheeks and around my mouth

volnema...may be the right choice in some cases.

It heats a broad area of the fat layer beneath the dermis to improve skin firmness and tightness.

I'm concerned about my double chin and sagging caused by fat

Prime Xwill be an option.

It targets fat with ultrasound while tightening the skin with RF.

I want to treat sagging skin, enlarged pores, and acne scars all at once

Mofius 8 burst...may be the right choice in some cases.

It takes a comprehensive approach to skin concerns—not just sagging, but also uneven skin texture, enlarged pores, acne scars, and loss of firmness.

I want to minimize pain and downtime as much as possible

Possible candidates include Volnuma and Prime X.

However, individual differences exist in how pain is perceived and in post-treatment reactions.

Prone to sunken cheeks / Low facial fat

Rather than focusing on the effects on fat, treatment plans should be designed with an emphasis on skin firmness and sagging.

For people with a slender build or those prone to sunken cheeks, it is important to adjust not only the type of device but also the treatment area, depth, output, and number of shots.

"Hyph is outdated" is a misconception | An era of choosing the right tool for the job

In recent years, as the range of RF treatment options has expanded, we’ve seen claims such as “RF is better than HIFU” and “HIFU is outdated.”

However, HIFU and RF differ in the energy they use and the depths at which they are most effective.

Hyfu excels at targeting deep layers, while Volnuma heats a broad area from the dermis to the fat layer.

Prime X works on both fat and skin in a comprehensive manner, while the Mofius 8 Burst delivers RF energy to multiple depths through the needles.

In other words, rather than treating everything with a single device,An Era of Tailoring Device Use to the Causes of Saggingis.

Can a hyphen and a pneumon be combined?

Since Hyph and Volnuma are suited for different client groups, they are sometimes used in combination during treatments.

By using Hyph to tighten deep tissues and Volnuma to deliver heat broadly from the dermis to the fat layer, we address sagging from different layers.

In addition, depending on the situation, the following combinations are also possible.

• Deep-Tissue Looseness + Skin Sagging: HIFU + Volnuma

• Excess Fat + Sagging Skin: Prime X + Volnuma

• Overall Firming + Pores and Skin Texture: Volnuma + Mofius 8 Burst

• Fat Reduction, Contouring, and Skin Texture Improvement: Prime X + Mofius 8 Burst

However, not everyone needs multiple treatments.

Since undergoing too many treatments can lead to excessive volume loss or downtime, we will assess the condition of your face and develop an appropriate treatment plan.

Frequently Asked Questions

Q. So, which treatment ultimately provides the best lifting effect?

It depends on the cause of the sagging.

If the main concern is deep tissue laxity, Hyfu is a good option; if it’s primarily skin laxity, Volnuma is recommended; if there is significant sagging due to fat, Prime X is a good choice; and if there are also issues with skin texture, Mofius 8 Burst is a viable option.

You can't simply compare them based on the hardware's performance alone.

Q. Can you feel a difference even after just one session?

Some people notice a tightening effect after just one treatment, but the way changes manifest varies from person to person.

With treatments that utilize collagen remodeling, changes may become apparent not only immediately after the procedure but also over time.

The number of sessions required and the intervals between treatments vary depending on the treatment and the condition of your skin.

Q. Which treatment causes the least pain?

In general, Volnuma and Prime X are treatments that are relatively gentle on the skin.

With Hyfu, you may experience a sensation of heat or a feeling that seems to radiate into the bones, depending on the treatment area; since the Mofius 8 Burst uses needles, it is performed under anesthesia.

Since pain tolerance varies from person to person, please consult with us in advance if you have any concerns.

Q. Can I apply makeup right after the treatment?

With Hyfu, Volnuma, and Prime X, you may be able to apply makeup immediately after the procedure, provided your skin is in good condition.

Since the Mofius 8 Burst treatment uses needles, please refrain from washing your face or applying makeup on the day of your treatment.

Our staff will provide detailed aftercare instructions following your treatment.

Q. Can people in their 20s and 30s take it?

Age alone does not determine whether a treatment is appropriate.

We will discuss treatment options tailored to your current concerns and skin condition, such as sagging along the jawline, loose skin, double chin, enlarged pores, and acne scars.

Q. What is the difference between this procedure and thread lifts or surgery?

The four procedures introduced here are non-surgical treatments using medical devices.

A thread lift physically lifts the tissue using threads, while a facelift surgically lifts the skin and deep tissues.

Depending on the degree of sagging, injectable treatments, thread lifts, or surgical procedures may be more appropriate than device-based treatments.

BIANCA CLINIC's Sagging Skin Treatments

At BIANCA CLINIC, rather than recommending a specific device across the board, we propose treatments based on the overall balance of your face.

Even when it comes to the same issue of “sagging along the jawline,” the causes vary from person to person—including skin laxity, fat volume, bone structure, asymmetry, and muscle development.

In addition, the extent to which people desire change and their tolerance for downtime vary from person to person.

Through counseling and medical examinations,

• Which demographic to target?

• Do I need to lose fat?

• Should we also perform skin treatment at the same time?

• Should it be done in a single session?

• Should I combine multiple treatments?

We will evaluate your condition and develop a treatment plan tailored to your specific situation and preferences.

Summary | It’s Important to Choose a Treatment That Suits Your Skin’s Sagging

Hyfu, Vornuma, Prime X, and Mofius 8 Burst are all non-surgical treatments for sagging skin, but they differ in the type of energy they use and the specific concerns they are best suited to address.

• Want to tighten your skin from deep within? HIFU

• Sagging skin and loss of firmness: Volnuma

• Fat-related sagging and double chin: Prime X

• Sagging, Pores, and Acne Scars: Mofius 8 Burst

The important thing is not to choose treatments that are currently popular or particularly intense, but to choose a treatment that addresses the specific cause of your sagging skin.
