Ultherapy PRIME is a high-intensity focused ultrasound (HIFU) system. How much changes, and when, varies widely between individuals, and it does not replace surgery or volume treatments. Suitability, shot count and fees need to be confirmed individually after consultation.

01Overview

Ultherapy PRIME Ultrasound lifting that reaches the SMAS layer

Ultherapy PRIME is a lifting treatment that delivers high-intensity focused ultrasound (HIFU) down to the SMAS layer — the thin sheet of connective tissue beneath the skin that supports the face.

Recommended sessions
About once a year recommended
Downtime
Immediate return to daily life; temporary swelling or tingling possible
How long it lasts
Typically 6 months to 1 year (individual results vary)

How we approach it

The same device can be run very differently. This is how Grays approaches this treatment.

We treat while checking the layers on the ultrasound screen. Even in the same area, the depth is adjusted to each person's skin thickness.

02What to expect

Changes over time

Guided by real-time ultrasound imaging, the device creates focal points of thermal coagulation that cause tissue to contract and stimulate new collagen, generating a gradual lifting effect.

Right after treatment01

Right after treatment

Mild flushing or swelling is possible, but most people return to daily life the same day. No wounds or crusts are left behind.

1 month02

1 month

Early collagen remodelling begins, and a subtle change in firmness appears first.

2–3 months03

2–3 months

New collagen continues to form, and changes in firmness and contour become clearer.

6 months04

6 months

The point at which the change comes close to its maximum. How much, and when, differs from person to person.

Follow-up05

Follow-up

It usually holds for six months to a year, and whether to treat again is decided after reviewing your own course, not on a fixed schedule.

Recovery & care

  1. 01

    First 1–2 hours

    Mild flushing and warmth are possible and usually settle within a few hours. You can wash your face and wear makeup the same day.

  2. 02

    First week

    Avoid strong heat — sauna, hot baths, heavy drinking — for a few days, and moisturise more than usual.

  3. 03

    1–12 weeks

    This is the collagen remodelling window. Use SPF 30 or higher every day to protect skin that is regenerating.

    Follow-up

07FAQ

Frequently asked questions

How does Ultherapy PRIME lift the skin?

It works by focusing high-intensity focused ultrasound (HIFU) down to the SMAS layer beneath the skin, creating small points of thermal coagulation. The heated tissue contracts, and as new collagen forms afterward, support develops that lifts sagging tissue. Because treatment is delivered while checking the layers on an ultrasound screen, the depth is adjusted to each person's skin thickness.

Who is Ultherapy suited to, and when is it not suitable?

We consider it for those whose jawline, cheeks, or brow line have started to sag, or who are bothered by a double chin and want to manage it without surgery. If sagging is already severe, non-surgical treatment alone has limits, and we will tell you honestly at consultation. It is not recommended if you have an implanted electronic medical device such as a pacemaker, have metal implants, infection, or wounds in the treatment area, or are pregnant.

Does Ultherapy hurt a lot? How is anesthesia handled?

Because energy reaches deep layers, there is a noticeable sensation, and how much you feel differs from person to person. Topical numbing cream is standard, and sedation support is also considered when needed. The treatment is performed directly by a board-certified dermatologist, who adjusts the intensity while watching your pain response.

How long does the treatment take?

It takes about 40-60 minutes depending on the area. Since the visit also includes consultation, topical numbing, and soothing care after treatment, your time at the clinic will be longer than this. We recommend allowing plenty of time in your schedule.

Can I return to daily life right after treatment?

Yes, you can return to daily life on the day of treatment, and you can wash your face and wear makeup. However, temporary swelling, tingling, or a muscle-ache-like sensation may continue for a few days.

When do results appear, and how long do they last?

Rather than right after treatment, results appear gradually over 2-3 months as collagen regenerates. Results typically last 6 months to 1 year, and the degree and timing of change vary by individual.

How often should I have Ultherapy?

About 1 session per year is recommended. Rather than repeating on a fixed date, we evaluate the progress from your previous treatment and then decide the timing and extent of the next one.

How is the number of shots decided?

We do not apply a set number of shots uniformly; it is decided after consultation according to the area, skin thickness, and degree of sagging. Because shots are allocated by area while viewing the layers on the ultrasound screen, the distribution may differ from person to person even for the same area.

Should I choose Ultherapy or Thermage?

It depends on which layer the sagging comes from. Ultherapy is relatively better suited to sagging of the SMAS layer, and Thermage to dermal firmness and fine lines. After consultation we recommend the device that matches the layer, and the two are sometimes planned together.

Can I have it together with Juvelook or Botox?

Because their goals differ, they are sometimes planned together. Where Ultherapy lifts sagging tissue, Juvelook addresses collagen production in hollow areas, and Botox addresses concerns related to muscle movement. Whether to do them on the same day or space them apart is decided after consultation, along with the order.

Are there side effects or precautions after treatment?

Temporary swelling or tingling may occur, and bruising or temporary reduced sensation may rarely occur. For a few days after treatment, avoid strong heat such as saunas, jjimjilbang (Korean bathhouses), and heavy drinking, and apply sunscreen of SPF30 or higher daily while collagen regenerates. If symptoms persist or worsen, please contact the clinic.

How much does Ultherapy cost, and how do I book?

The cost depends on the area and number of shots, so it is confirmed after consultation, and reference prices can be found on the price list on our website. Booking is available via Naver Booking, our KakaoTalk channel, or phone (+82-51-710-1891), and consultations are also available via LINE.

Aftercare

Draft — pending medical director's review

Ultrasound lifting

Energy is delivered to the SMAS layer without breaking the skin surface, so you can return to daily life the same day. The change follows the pace of collagen renewal and appears gradually.

Recovery course

  1. Day of treatmentMild tingling and slight redness are possible. You may wash your face and apply skincare as usual.
  2. Days 2–3A pressed, achy feeling may remain. If chewing is uncomfortable, avoid hard foods for a while.
  3. Weeks 1–2Swelling and tingling usually settle. Photos from this period are too early to judge the change.
  4. Months 2–3Collagen rebuilds and the change becomes clearer. This is when the result is assessed.

Avoid during this period

  • Sauna, hot baths, strenuous exercise and alcohol — for 3–5 days after treatment
  • Rubbing or massaging the treated area firmly — for 1 week

Contact the clinic if

  • Swelling on one side keeps getting worse
  • One side of the face feels weak or your expression looks asymmetric
  • Blisters or burn-like marks appear

Next session · next visitUsually reviewed every 6–12 months, depending on age and the degree of laxity, decided at consultation.

Individual recovery varies. If it differs from what you expected, do not judge on your own — please contact the clinic. Tel +82-51-710-1891
