Hello.

I’m Kim Ha-won from Beauty’s Doctor.

As you prepare for an Ultherapy consultation,

the numbers most commonly searched for are probably

300 lines, 400 lines, and 600 lines.

You may think that receiving fewer lines will not produce a change,

while receiving more will make the results more certain,

but the actual treatment plan is not that simple.

Even with the same 400 lines, the treatment can be entirely different

depending on which areas they are assigned to

and at what depths.

Three-line summary

  1. With Ultherapy, it is more important how the lines are distributed across the areas and depths that need treatment than simply whether there are more or fewer lines.

  2. The total number should be determined after considering facial area, skin thickness, fat volume, and the locations of sagging and hollowness.

  3. During your consultation, check not only the total number of lines but also how they are distributed by area and which areas should be avoided.

  1. It is difficult to determine whether 300 lines are enough based on the number alone

Online, 300 lines are often compared as the standard,

while 600 lines are presented as a more intensive treatment.

However, a partial treatment focused only on the jawline

cannot be compared with a plan covering the entire face

and including beneath the chin using the same number.

If your face is small and sagging is concentrated in specific areas,

fewer lines may be enough

to cover the necessary range.

Conversely, if your face has a larger treatment area

or the area beneath the chin is included,

more lines may be needed.

So rather than asking, “How many lines are appropriate?”

a more accurate question is,

“Which areas of my face should be treated first?”

The number of lines is not the starting point of the plan.

It is closer to the result that follows

after the treatment areas and depths have been determined.

  1. Why the same 400 lines can produce different results

Ultherapy delivers focused ultrasound energy

in point-like applications to the target depths beneath the skin,

creating thermal coagulation points.

The dermal layer and the deeper supporting layer

can be divided according to the treatment area,

and one of its features is that energy is delivered

while checking tissue depth through real-time ultrasound imaging.

Therefore, what matters is not only

how many lines were delivered.

You should also check whether they reached the target layers accurately

and whether enough were allocated to the sagging jawline

and the area beneath the cheeks.

At the same time, it is important to confirm

that the front cheeks and temples,

where volume should be preserved,

were not unnecessarily treated.

In particular, if you have little facial fat

and hollowness beneath the cheekbones or in the front cheeks,

applying many lines uniformly

may make the hollowness appear more pronounced

rather than providing the lifting you wanted.

Conversely, if you have fat beneath the chin

along with sagging in the lower face,

the plan can emphasize the jawline and area beneath the chin

while varying the depth and direction.

  1. In the treatment room, we look at this before the number of lines

What I check first during a consultation is not

“How much should we apply?”

but rather,

“Which areas should be lifted, and where should volume be preserved?”

I check whether the cheek fat

is actually sagging downward,

whether the area appears hollow

because there is little fat,

and whether fat beneath the chin

is making the facial contour look heavier.

It is also necessary to check

which areas show noticeable asymmetry between the two sides.

A history of recent filler treatments, thread lifting,

or other radiofrequency or ultrasound treatments is also important.

This is because when stimulation overlaps in the same area,

it may be necessary to adjust the intensity, range, and timing.

During your consultation, along with the total number of lines,

ask how many will be allocated to the jawline, cheeks, and area beneath the chin,

and which depths will be used primarily.

It is also a good idea to ask

how areas with hollowness will be avoided or protected.

The more specific the explanation,

the easier it is to determine whether the treatment is a plan tailored to your face

rather than simply a purchase of a number.

  1. Do not judge the treatment as insufficient based only on the immediate result

Some people feel tightening immediately after Ultherapy,

but as the tissue recovers

and collagen remodeling continues,

changes are often observed over several weeks to several months.

Rather than looking in the mirror right away

and concluding, “Were there not enough lines?”

it is better to take photos under the same lighting and from the same angle

and observe the flow of your facial contours.

Redness, swelling, tenderness,

and a tingling sensation

may temporarily occur after the treatment.

While the heat sensation remains,

please postpone saunas, Korean-style heated rooms, hot showers,

strong facial massages, and strenuous exercise for a while.

If the pain gradually worsens,

reduced sensation or numbness continues for an extended period,

or facial asymmetry or changes in skin color appear,

do not simply wait on your own.

Contact the medical institution where you received the treatment.

In closing

With Ultherapy, a higher number of lines

does not mean a better score.

More important than the difference between 300 and 600 lines

is whether enough were delivered to the areas that needed treatment

and whether areas whose volume should be preserved were left alone.

Rather than deciding on the total amount first,

we first examine skin thickness, fat distribution,

and the locations of sagging and hollowness.

Then we explain how the priorities by area

and the distribution of lines will differ.

Before your consultation, ask just two questions.

“Which area of my face should be treated first?”

“How is that assessment reflected

in the distribution of lines and depths?”

If the explanation makes sense to you,

the vague anxiety caused by focusing on the numbers

may also feel much more manageable.

Frequently asked questions

Q1. Are 300 Ultherapy lines enough for the entire face?

It depends on the size of your face and the areas included.

You should first confirm whether the treatment focuses on the jawline

or also includes the cheeks and area beneath the chin.

Q2. If there are more lines, will the results last longer?

The number of lines and the duration of the results

do not increase in direct proportion.

Their distribution and depth, along with your skin condition and rate of aging,

may all have an influence.

Q3. Can I receive the treatment even if I have little facial fat?

This is determined after checking areas of hollowness and the amount of fat.

Areas where volume should be preserved can be avoided,

and the treatment range can be adjusted to focus on the necessary supporting areas.

Q4. If there is little immediate change, can I receive additional lines right away?

It is too early to judge whether the treatment was insufficient

based only on how it feels immediately afterward.

It is safer to check your progress first and discuss the need for additional treatment and the interval with your medical professional.
