Diagnose laxity versus fullness
Loose skin and submental tissue can create similar shadows but require different treatment priorities.
LOUAVE Lifting Center
Ultherapy vs ONDA: lifting or contouring for your concern?
Compare two different non-surgical approaches available at LOUAVE Dermatology Clinic in Seoul. Ultherapy is primarily a focused-ultrasound lifting treatment, while ONDA may be considered for selected contour, under-chin fullness and skin-firmness concerns.
A soft jawline or double chin may be caused by skin laxity, submental tissue, muscle activity, posture, swelling or facial structure. Device selection should follow diagnosis rather than the treatment name alone.

Understanding the Difference
01
02
03
Ultherapy lifts selected tissue. ONDA addresses selected contour concerns.
Ultherapy combines microfocused ultrasound energy with real-time ultrasound visualisation. It is commonly considered when mild to moderate tissue laxity contributes to a softened brow, lower face, neck or under-chin area.
ONDA uses controlled 2.45 GHz Coolwaves microwave energy. Its different handpieces may be considered for selected submental tissue, localised fullness and skin-firmness concerns.
Review facial and neck anatomy
Chin projection, jaw shape, platysmal activity and posture influence the visible jaw-to-neck transition.
Avoid unnecessary volume reduction
Reducing tissue where facial support is already limited may create unwanted hollowness or imbalance.
Technology Explained
Focused ultrasound versus Coolwaves microwave energy.
These technologies deliver energy differently and should not be treated as interchangeable solutions for every jawline or double-chin concern.
Microfocused Ultrasound
Ultherapy
Ultherapy uses real-time ultrasound visualisation to examine tissue before delivering focused ultrasound energy at selected depths. Treatment is planned around lifting and tightening rather than predictable fat removal.

Compare by Underlying Concern
The visible problem may not be the actual treatment target.
A clinical assessment should identify the tissue layer responsible for the concern before either device is selected.
Skin Laxity
When loosened tissue is the primary concern, a lifting-focused treatment such as Ultherapy may be discussed.
Common discussion: UltherapySubmental Fullness
When selected superficial tissue contributes to a double chin, ONDA may be considered after thickness assessment.
Common discussion: ONDAMixed Laxity & Fullness
Some patients have both loose tissue and localised fullness, requiring staged or combination planning.
Individual sequencingSmall or Recessed Chin
Limited chin projection can make the under-chin area appear fuller even when tissue volume is not excessive.
Structural assessment requiredPlatysmal Bands
Prominent neck-muscle bands require a different treatment discussion from loose skin or submental tissue.
Neither device alone may applyAdvanced Laxity
Significant excess skin may not respond sufficiently to non-surgical lifting or contouring treatments.

Treatment Selection Process
Meet the LOUAVE Doctors →
Choose the tissue target before choosing the device.
LOUAVE reviews skin laxity, submental tissue, jaw structure, neck anatomy, previous procedures and the amount of change expected before recommending treatment.
Consultation & History Review
The doctor discusses your concern, medications, medical history and previous facial or neck procedures.
Laxity & Tissue Assessment
Skin mobility, tissue thickness, jawline structure and the jaw-to-neck angle are examined.
Device Selection
The clinician decides whether Ultherapy, ONDA, another treatment or no procedure is appropriate.
Mapping & Treatment
Treatment areas are mapped and device-specific gel, oil, imaging or cooling measures are used.
Aftercare & Review
Expected recovery, precautions and the appropriate time for evaluating gradual changes are explained.
Recovery & Result Development
Temporary tissue response is not the final result.
Early appearance may be influenced by redness, swelling, tenderness or temporary firmness after treatment.
Treatment Day
Temporary redness, warmth, tenderness, swelling or sensitivity may occur after either treatment.
Early Recovery
Tingling, bruising, tenderness, firmness or temporary altered sensation may continue while the area settles.
Developing Change
Lifting, contour or firmness changes may become more noticeable gradually and vary between patients.
Clinical Review
Additional treatment should be discussed only after reviewing the response and remaining concern.
Which May Suit You?
A general guide before your clinical assessment.
These points describe common consultation pathways. They do not confirm suitability or guarantee results.
Ultherapy may be discussed when:
- Skin or tissue laxity is the main concern.
- The jawline, neck or under-chin area appears less firm.
- Real-time ultrasound visualisation is relevant to planning.
- Focused treatment at selected depths is considered appropriate.
- You understand that visible lifting develops gradually.
ONDA may be discussed when:
- Selected submental or lower-face fullness is the main concern.
- Tissue thickness is appropriate for contour treatment.
- Mild skin-firmness concerns occur with localised fullness.
- Microwave treatment is medically suitable.
- You understand that fat reduction and contour change vary.
Can Ultherapy and ONDA be included in one plan?
A clinician may discuss staged or combination treatment when both tissue laxity and selected localised fullness contribute to the jawline or under-chin concern. Every patient does not require both devices.
Confirm that two different tissue concerns exist
Map lifting and contour areas separately
Review previous energy and injectable procedures
Assess the response before adding further treatment
Frequently Asked Questions
Questions about Ultherapy vs ONDA.
Final recommendations depend on anatomy, tissue thickness, medical history and the change you want to discuss.
Is Ultherapy better than ONDA?
Neither treatment is universally better. Ultherapy is
primarily lifting focused, while ONDA may be considered
for selected contour, submental tissue and firmness
concerns. The correct choice depends on diagnosis.
What is the main difference between Ultherapy and ONDA?
Ultherapy uses microfocused ultrasound with real-time
tissue visualisation. ONDA uses 2.45 GHz Coolwaves
microwave energy delivered through controlled handpieces.
Which treatment is better for loose skin?
Ultherapy may be discussed when selected tissue laxity
is the primary concern. ONDA may also support selected
firmness concerns, but the treatment objective and
tissue depth differ.
Which treatment is better for a double chin?
The answer depends on whether the visible double chin
is mainly caused by loose skin, selected submental
tissue, chin structure, muscle activity or a combination.
Can ONDA remove all under-chin fat?
No predictable or complete fat removal should be
guaranteed. Visible response depends on tissue thickness,
anatomy, treatment coverage and individual biology.
Can Ultherapy reduce facial fat?
Ultherapy should primarily be planned as a lifting and
tightening treatment. It should not be presented as
predictable facial-fat removal.
Which treatment is more comfortable?
Sensation varies by treatment area, settings and
personal sensitivity. Ultherapy may feel focused or
intense, while ONDA is commonly experienced as warmth
or pressure with cooling support.
Can Ultherapy and ONDA be combined?
They may be staged or combined for selected patients
when both laxity and localised fullness are present.
Treatment areas, timing and previous procedures must
be reviewed carefully.
Can either treatment reshape my jawbone or chin?
No. Neither Ultherapy nor ONDA changes bone structure
or adds chin projection. Structural concerns require
a different treatment discussion.
Can international patients arrange consultation before arriving?
International patients can share photographs, priority
areas, medical history, previous treatments, preferred
appointment dates and Seoul travel plans. Final device
selection requires consultation.
International Appointment
Choose Ultherapy or ONDA after the right diagnosis.
Share whether your concern involves the jawline, neck, under-chin area or lower face, together with previous lifting, contouring and injectable treatments, medical history and Seoul travel dates.
Important treatment information
This page provides general educational information and does not replace an individual medical consultation. Ultherapy and ONDA use different technologies, and neither is suitable for every patient or concern. Treatment areas, settings, handpiece or transducer selection, comfort measures, recovery and results vary. Temporary effects may include redness, warmth, swelling, tenderness, bruising, tingling, numbness, firmness, sensitivity or discomfort. Less common complications may include burns, prolonged pain, nerve-related symptoms, pigmentation change, skin-surface injury, contour irregularity or scarring. Patients should disclose pregnancy or breastfeeding status, active infection, open wounds, relevant implants or medical devices, circulation or sensation disorders, neurological conditions, previous surgery, injectables and earlier energy-based treatments. Neither device reshapes bone, guarantees fat reduction or reproduces surgical lifting. Significant tissue laxity or structural concerns may require another treatment or a surgical opinion. Final treatment planning must follow assessment by an appropriately qualified medical professional.
