Myeongdong ONDA Lifting: How Microwave Lifting Works & What to Know Before Treatment

 Hello,

I’m Dr. Youjoo Hwang, 

Director of Lijin Clinic in Myeongdong, Seoul.

In clinic, 

many patients searching for 

lifting treatments in Myeongdong 

come in with concerns like:

“My face looks heavier than before”

“My jawline has become less defined”

For these concerns, 

we often recommend ONDA lifting,

a non-invasive microwave-based lifting treatment 

that targets both skin laxity and facial contour.

Today, I’ll explain:

✔ how ONDA lifting works

✔ what makes it different from RF lifting

✔ what to consider before treatment

"The Principles of ONDA Lifting"

1. What Is ONDA Lifting? (Microwave Lifting Technology)

ONDA lifting is 

a microwave-based skin tightening treatment

that delivers energy into the deeper layers of the skin.

Unlike traditional RF lifting treatments,

ONDA penetrates deeper, targeting:

✔️ the dermis (collagen layer)

✔️ the subcutaneous fat layer

This is made possible 

through Coolwaves™ technology,

which allows selective energy delivery 

while minimizing damage to surrounding tissues.

2. ONDA vs RF Lifting: What’s the Difference?

ONDA lifting reaches deeper layers than RF lifting

The key difference lies in depth and selectivity:

RF lifting

→ primarily targets the dermis

→ focuses on skin tightening

ONDA lifting (microwave)

→ reaches both dermis and fat layer

→ improves firmness + reduces localized fat

Because of this, 

ONDA is not just about tightening—

it also helps with facial contouring and jawline definition.

3. How ONDA Improves Skin & Contour

Before (left) and after (right): 

the epidermis (dark pink) remains unchanged, while collagen activity is stimulated within the dermis

ONDA works through two main mechanisms:

In the dermis

→ stimulates collagen production

→ improves skin elasticity and texture

In the fat layer

→ reduces excess fat gradually

→ refines facial contours

This dual effect makes ONDA a popular option for patients looking for:

✔️ non-surgical face slimming

✔️ jawline contouring in Myeongdong

✔️ lifting without downtime

Results develop gradually over 2–3 months,

as collagen remodeling and fat reduction take place.

4. 3mm vs 7mm Handpiece: Why It Matters

ONDA uses different handpieces depending on treatment depth:

3mm handpiece

→ targets dermis

→ improves skin texture and firmness

7mm handpiece

→ targets subcutaneous fat

→ reduces localized fat and defines contour

Choosing the correct depth is essential because:

✔️ facial areas vary in skin thickness

✔️ fat distribution differs across regions

✔️ treatment goals are highly individual

A customized approach helps achieve

natural-looking, balanced results.

5. Who Is a Good Candidate for ONDA Lifting?

ONDA is commonly recommended for patients who

✔️ notice facial heaviness or mild sagging

✔️ want jawline definition without surgery

✔️ are looking for non-invasive lifting in Seoul

✔️ have localized facial fat (lower face, chin area)

"What to Consider Before ONDA treatment"

Although ONDA is a relatively gentle treatment,

there are important factors to consider.

1) Facial Balance Matters

Each area of the face serves a different purpose:

✔️ some areas require volume preservation

✔️ others benefit from fat reduction

Treating all areas the same can lead to

unnatural volume changes.

2) Energy Control Is Key

Since ONDA uses heat energy:

✔️ excessive energy in one area should be avoided

✔️ proper movement speed and technique are essential

3) Treatment Timing

If you’ve recently had

 skin boosters (Rejuran, Juvelook, etc.) 

or regenerative treatments,

we recommend waiting 

at least 2 weeks before ONDA.

4) Possible Temporary Reactions

Depending on your skin condition, 

you may experience

mild warmth or temporary sensitivity.

These are usually short-lived.

Myeongdong Rejuran: From Types to Selection Criteria — A Complete Guide

Hello,

This is Dr. Hwang Youjoo, 

Medical Director of Lijin Clinic.

Lately, one phrase I hear often in the consultation room is:

“After trying many things, 

I keep coming back to Rejuran.”

While a wide range of skin boosters 

has emerged over time, 

many patients eventually return 

to what feels like 

the “fundamentals”—Rejuran.

Rather than being a passing trend, 

Rejuran has established 

a solid level of trust 

among both local and international patients.

In recent years, 

it has also gained consistent attention overseas, 

with frequent mentions 

among celebrities and global beauty communities, 

further reinforcing its reputation.

Today, 

I’d like to walk you through everything

- from its core ingredient 

to the differences between each type, 

and how to choose the most suitable option for your skin

just as I would explain during a consultation.

“The Key to Skin Regeneration: PN”

1. The Key Ingredient of Rejuran: How PN Works

The most important concept to understand 

when discussing Rejuran is PN (Polynucleotide).

PN consists of DNA fragments

derived from salmon, 

known for their high biocompatibility,

allowing them to interact safely and effectively with human skin.

As we age, 

the skin naturally undergoes several changes:

✔️ Slower cellular turnover

✔️ Reduced collagen production

✔️ Loss of elasticity and changes in skin texture

Rejuran works differently 

from treatments that simply “fill” the skin.

Instead, 

it delivers PN into the dermis, 

helping to create an environment 

where the skin can restore itself.

It supports tissue repair 

and stimulates fibroblasts, 

promoting the production of collagen and elastin.

In other words,

this is not a treatment that temporarily fills the surface,

but one that helps restore the skin’s fundamental health.

Because of this mechanism, 

results tend to appear gradually over time, 

leading to natural and long-lasting improvements 

rather than immediate dramatic changes.

2. Types of Rejuran (Healer / HB / I / S)

Rejuran offers several variations, 

each designed for specific concerns and skin conditions.

✔️ Rejuran Healer

The original and most fundamental formulation, 

based on pure PN.

It focuses on overall skin regeneration, 

improving elasticity and texture, 

and enhancing overall skin quality.

✔️ Rejuran HB (Hydro Booster)

A combination of PN, hyaluronic acid, and lidocaine.

It offers added hydration and glow 

while reducing discomfort during the procedure.

Especially suitable for those 

with dry skin or sensitivity to pain.

✔️ Rejuran I (Eye)

A low-viscosity PN formulation 

specifically designed for the delicate eye area.

It helps improve fine lines 

and elasticity around the eyes 

with minimal burden on thin, sensitive skin.

✔️ Rejuran S (Scar)

A high-viscosity PN formulation 

targeted for localized concerns 

such as acne scars and enlarged pores.

Ideal for areas that require more intensive, 

focused treatment.

3. How to Choose the Right Rejuran for You

This is the most important part.

Even within the Rejuran line, 

there is no single “best” option for everyone.

The right choice depends on multiple factors, including:

✔️ Your skin condition

✔️ The area of concern

✔️ Sensitivity to discomfort

✔️ Desired outcome (immediate glow vs. long-term improvement)

For example:

• Overall thinning skin and reduced elasticity → Rejuran Healer
• Dryness, glow, and lower pain tolerance → Rejuran HB
• Fine lines around the eyes → Rejuran I
• Scars or enlarged pores → Rejuran S

Even with the same product, 

results can vary significantly 

depending on how the treatment is planned and performed.
