Ultherapy Prime Q&A | Summary of the Procedure’s Principles and Features image 1

Hello,

This is the official blog of Forena Clinic,

aiming for premium anti-aging

and healthy beauty. 😊

Recently, among those who want

more precise and natural improvement

of sagging and lifting effects,

the procedure drawing the most attention is

‘Ultherapy Prime.’

Today, from the principles of Ultherapy Prime

to its effects, pain, and duration,

we will easily organize the key points

that many people are curious about

in a Q&A format.

Q1. What kind of procedure is

Ultherapy Prime?

Ultherapy Prime

is a non-surgical lifting procedure that uses

high-intensity focused ultrasound (HIFU)

to deliver energy

deep into the SMAS layer

without damaging the skin surface.

It directly contracts and lifts sagging tissue,

and then induces collagen regeneration,

restoring firmness from within the skin

and clearly improving facial contours.

Compared with previous devices,

it offers higher energy delivery and precision,

so more even and effective results

can be expected.

Q2. Personalized lifting:

Ultherapy Prime

Because everyone has different skin thickness,

degrees of sagging,

and patterns of aging,

results can vary even with the same lifting procedure.

That is why, for highly satisfying results,

precise targeting tailored to the area

and skin condition is important,

rather than a one-size-fits-all procedure.

Hongdae Ultherapy Prime uses

three depth-specific tips:

1.5 mm, 3.0 mm, and 4.5 mm,

allowing customized treatment that delivers

different energy depending on the skin layer.

1.5 mm tip (fill)

It works on the thin skin layer

and densely induces collagen regeneration.

It is effective for improving fine lines

and supplementing subtle volume

around the eyes, nasolabial folds,

and forehead.

3.0 mm tip (reduce)

It acts on the subcutaneous fat layer

and the shallow SMAS layer,

helping to refine sagging cheek volume

and unnecessary fullness.

It makes the double chin and jawline

look slimmer and more defined.

4.5 mm tip (lift)

It works deeply down to the SMAS layer

to strongly lift sagging skin.

It helps complete a firm and defined jawline.

When tips of different depths are strategically used

in combination according to skin condition,

the balance of the entire face can be naturally adjusted

and the collagen regeneration effect can be maximized.

Q3. Differences from Thermage FLX

Many people also wonder about

the difference from Thermage.

Both procedures share the common point

of inducing collagen regeneration

and providing anti-aging effects,

but there are differences in

the depth where the energy acts

and the purpose of the treatment.

Ultherapy Prime uses

ultrasound (HIFU) energy

to act all the way down to the SMAS layer,

the deep layer of the skin,

making it a lifting-focused procedure

that raises sagging skin.

It is particularly strong

for improving sagging across the face

and creating a clear contour line.

On the other hand, Thermage FLX

delivers radiofrequency (RF) energy

broadly, mainly to the dermis,

focusing on surface tightening,

smoother skin texture,

and restoring firm elasticity.

Q4. Ultherapy Prime

What are the treatment effects and recommended interval?

Many people hesitate to undergo lifting procedures

because of concerns about pain.

Ultherapy Prime may be accompanied by

a slight dull or pulling sensation

as ultrasound energy is delivered

to the deeper layers of the skin.

However, at Forena Clinic,

we minimize discomfort by providing

sufficient anesthesia before the procedure,

so most patients receive treatment comfortably.

Immediately after the procedure,

depending on the individual,

slight swelling, redness,

or minor bruising may appear.

However, in most cases,

these symptoms naturally ease within 1 to 2 days,

and daily life is generally not significantly affected.

✨ When the treatment effects appear

Right after the procedure,

you may feel mild tightening,

and as time passes,

collagen regeneration progresses.

Usually, noticeable lifting effects

begin to appear about 1 month after treatment.

✨ Duration of the treatment effect

The formed firmness and lifting effect

last for about 6 months to up to 12 months.

Depending on your skin condition and lifestyle,

we recommend regular treatment about once a year. 😊

Q5. Ultherapy Prime

Recommended for these people.

No matter how good the device is,

the results ultimately depend on
