Doctors' Point

“I’m interested in PrimeX, but will it really be effective? And what about pain and downtime?” These are the two concerns most commonly raised during consultations at cosmetic dermatology clinics. Rather than rushing to a conclusion, understanding how the treatment works and determining whether it’s right for you will lead to a choice that brings greater satisfaction.

 

PrimeX combines radiofrequency (RF) and ultrasound (US), allowing it to simultaneously address sagging, facial contours, skin firmness, and volume in certain areas. The effects of PrimeX occur in two stages: an “immediate tightening sensation” right after the treatment, followed by changes resulting from collagen regeneration that develop over 1 to 3 months, making it a convenient cosmetic dermatology option even for busy individuals. Results generally last approximately 6 to 12 months, though this may vary from person to person.

 

In this article, from the perspective of a cosmetic dermatologist, we’ve organized the information we discuss in our clinic—including how PrimeX works, its effects, the process of seeing results, tips for maintaining results, how it differs from other treatments, risks, and frequently asked questions—in a way that’s as easy to understand as possible.

What Is PrimeX? | How It Works from a Cosmetic Dermatologist’s Perspective and How PrimeX Delivers Results

PrimeX is a cosmetic medical treatment that combines radiofrequency (RF) and ultrasound to deliver thermal energy to the dermis and subcutaneous fat.

 

The goal is to temporarily contract collagen using heat, thereby promoting the production of new collagen and elastin during the subsequent repair process. Furthermore, a key feature of this method is that the use of ultrasound helps disperse the heat more easily, allowing for uniform heating.

The Two-Stage Effects of Prime X

• Immediately after the treatment: The heat causes existing collagen to contract, and some people feel a tightening sensation (results may vary from person to person).

•  

• Weeks 2–12: As fibroblasts are activated and new collagen is produced, you’ll likely notice improvements in firmness and elasticity, as well as a more defined jawline and a slimmer-looking face.

Estimated Downtime and Pain

Downtime is often relatively minimal, and mild redness or a sensation of warmth typically lasts anywhere from a few hours to a few days.

 

The perception of pain varies from person to person and depends on the output level and treatment area. In cosmetic dermatology, we do not rely solely on intensity; instead, we determine the “necessary and sufficient energy” to strike a balance between comfort and safety.

Duration and Maintenance (Recommendations from a Cosmetic Dermatology Clinic)

The effects generally last approximately 6 to 12 months. Results may vary depending on age, skin thickness, body fat, and lifestyle factors (sun exposure, smoking, sleep, and weight fluctuations).

 

At our cosmetic dermatology clinic, we often recommend maintenance treatments every six months to a year, and we’ll work with you to create a manageable schedule that fits your season and plans.

Key Changes You Can Expect with PrimeX

Toning the Jawline

As we age, the skin and subcutaneous tissue lose their firmness, leading to concerns about a blurred facial contour and sagging under the chin. PrimeX delivers heat to the dermis and subcutaneous fat to tighten the tissue and refine the facial contour.

 

While some people experience a mild sense of refreshment immediately after the treatment, for most, the changes occur gradually over a period of several weeks to several months.

Support for a Smaller Face

Thermal energy also affects the volume of fat cells, making it a good fit for people who are concerned about a double chin or a thick jawline.

 

Since this treatment is not intended for excessive weight loss, it is particularly well-suited for those who simply want to look naturally slimmer.

Skin Firmness and the Appearance of Pores

As collagen and elastin are rebuilt, you can expect improvements in firmness, skin texture, and smoothness.

 

It can also be incorporated as a foundational treatment for skin concerned with visible pores and fine lines (the degree of reaction varies from person to person).

Improving Sagging Skin

It helps firm areas prone to signs of aging, such as the cheeks, jawline, marionette lines, and under the chin.

 

In cases of significant excess skin or severe sagging, we may consider combining this treatment with other options (such as sutures or surgical procedures). In cosmetic dermatology, we carefully discuss the risks and expected outcomes with you.

Partial Body Toning

It is used not only on the face but also on areas where "sagging and excess volume" coexist, such as the abdomen, upper arms, thighs, hips, and back.

 

We aim to gently firm up areas where the skin has lost its firmness—a condition that is difficult to improve through exercise or diet alone—within reasonable limits.

How to Interpret "Before & After" Images and Points to Note

When comparing "Before" and "After" photos, keep in mind the effects of the camera angle, lighting, makeup, and changes in weight.

 

Since there is significant individual variation in this area, it is important not to make a judgment based solely on photographs, but to undergo a comprehensive evaluation at a cosmetic dermatology clinic that takes into account skin type, body fat, and bone structure.

Assessing at a Cosmetic Dermatology Clinic: Determining Suitability and Maximizing the Effects of prime X

Key Points to Check During an Examination

• Main cause of the concern: Is it primarily due to sagging skin, excess fat, or the effects of swelling or muscle tension?

• Skin Thickness and Elasticity: Factors Affecting Heat Transfer and the Manifestation of Reactions

• Fat Distribution: Directly Affects the Shape of the Jawline and Under-Chin Area

• Lifestyle: Sun exposure habits, sleep, weight fluctuations, schedule (tolerance for downtime)

• Desired level of change: A natural change or a more dramatic one?

Suitable for

• I want to firm up mild to moderate sagging along my jawline

• I want to naturally make my face look slimmer and more firm

• I want to choose a treatment with minimal downtime

• I can accept the process of gradually getting things in order

People who want to consider this carefully

• Significant excess skin; severe sagging

• I strongly hope to see a dramatic change in just one go.

• Recent severe sunburn or active skin inflammation

• There are circumstances that require advance disclosure, such as whether you have any implanted medical devices or pre-existing medical conditions

Recommended by Aesthetic Dermatologists: Daily Care Tips to Maximize and Maintain the Effects of prime X

UV Protection

Ultraviolet rays break down collagen, leading to a loss of firmness. Make it a habit to use sunscreen, wear a hat, and carry a parasol. Taking extra care immediately after your treatment is especially important.

Adequate Moisturization

Dryness can weaken the skin’s barrier function and lead to prolonged redness and irritation. Consider layering toner, lotion, and cream, or using products formulated for sensitive skin.

Protein and Vitamin C

Collagen is made from protein, and vitamin C helps with its synthesis. Eat a balanced diet of meat, fish, eggs, and soy products, and supplement your intake of vitamin C with vegetables and fruits.

Sleep, Smoking Cessation, and Weight Management

Good-quality sleep supports the body's healing process. Since smoking affects blood flow and collagen metabolism, it's best to limit it. Sudden weight fluctuations can affect the appearance of your facial contours.

Differences from Other Sagging Treatments | The “Right Fit” Perspective Valued by Cosmetic Dermatology

HIFU is particularly effective at precisely heating deep layers to achieve a lifting effect, while radiofrequency alone is particularly effective at heating the dermis to enhance skin firmness.

 

PrimeX combines radiofrequency and ultrasound, and because its design allows heat to be delivered deeply into the dermis and subcutaneous fat, it is particularly well-suited to addressing a range of aesthetic goals, including skin tightening, firmness, and facial slimming. The fundamental approach in cosmetic dermatology is not to identify a “best” option, but to select a treatment based on the patient’s specific concerns, lifestyle, and acceptable level of downtime.

This is likely to meet such expectations

• I want to naturally smooth out blurry edges

• I'm concerned about both a lack of firmness and a lack of volume

• I want to keep downtime to a minimum

Risks, Side Effects, and Precautions (Information from the Cosmetic Dermatology Department)

Temporary redness, warmth, swelling, or a mild, muscle-ache-like discomfort may occur. In rare cases, blisters, changes in skin color, or nerve-related discomfort have been reported.

 

Results, pain, downtime, and duration of effects vary from person to person and may differ even within the same person depending on the treatment area. Please be sure to inform your cosmetic dermatologist of your current health condition, any medications you are taking, your medical history, whether you have any implanted medical devices, and any recent sun exposure or prior treatments.

 

We will carefully determine the output settings and treatment intervals during your consultation to ensure your safety.
