10 Essential Pre-Procedure Facts Explained Directly by the Doctor at Hongdae Ulthera

"It works on the same principle as grilling meat"

— The true mechanism of Ulthera

Hello.

This is Beauty’s Doctor, Wi Youngjin.

When you search for Hongdae Ulthera,

you see a lot of difficult medical terms.

Since many people were curious,

I organized everything one by one myself.

✅ 1. By what principle does Ulthera regenerate collagen?

"When meat touches fire,

the surface contracts as it cooks.

Ulthera works the same way.

It uses thermal energy to coagulate and contract

the collagen inside the skin."

Ulthera uses high-intensity focused ultrasound (HIFU)

to send energy deep into the skin,

concentrating heat on specific layers.

As this heat coagulates and contracts collagen,

it creates an immediate lifting effect,

and at the same time, the body receives a signal to

'heal the damage!' and begins producing new collagen.

✅ 2. Immediate changes vs. long-term effects

Right after the procedure,

you may feel a slight tightening sensation,

and over the long term, new collagen is produced

and acts as support inside the skin.

It takes time for collagen to regenerate sufficiently.

Usually, the effects become clear starting

2 to 3 months after the procedure,

and it is common for improvement to continue

gradually for up to 6 months.

✅ 3. What is the most uncomfortable part during the procedure, and what is the solution?

I’ll be honest.

The discomfort most often felt during Hongdae Ulthera

is a tingling, sharp sensation.

It is the sensation felt when ultrasound energy

is concentrated deep inside the skin,

and for sensitive people,

it can feel quite strong.

💡 The solution is injection anesthesia.

By using anesthetic injections before the procedure,

discomfort can be greatly reduced.

If you are worried about pain,

please be sure to mention it during your consultation!

✅ 4. How does the skin change step by step after the procedure?

Ulthera is not a procedure

for improving skin trouble,

but a procedure intended for lifting and tightening.

Immediately after the procedure, there may be slight swelling

along with a feeling of tightening,

and from 1 to 2 months later,

collagen regeneration begins

and support inside the skin starts to build.

The period from 3 to 6 months

is when the lifting effect

becomes most noticeable.

✅ 5. Which areas is Ulthera especially effective for?

Deep cheek area (to improve sagging cheeks)

Nasolabial fold area

Cheekbone line

Jawline

✅ 6. Are there cases where you should not receive it?

Yes, this is something

that must be checked.

⚠️ If you have a thyroid-related condition,

procedures on the neck area should be avoided.

This is because ultrasound energy may affect

the thyroid area.

Before the procedure, be sure to inform the medical staff

of any underlying conditions.

✅ 7. Is special skin care needed after the procedure?

Many people ask, "What should I apply after getting

Hongdae Ulthera?"

To give the conclusion first,

there is nothing special to be careful about after the procedure,

and it is not directly related to skin care either.

You can return to daily life immediately,

and you can fully benefit from the effects

without any special aftercare.

✅ 8. Does the effect accumulate if you repeat the procedure?

"It’s like hanging up several fishing lines.

But over time, even fishing lines tend to stretch like rubber bands."

Yes, there is a cumulative effect.

Repeated procedures add to the supportive effect,

but collagen can also stretch again as you age.

Regular maintenance helps preserve the effect.

✅ 9. What is the most common misconception about Ulthera?

"If you get Hongdae Ulthera,

won’t your cheeks look sunken?"

I get this question very often.

To give the conclusion first, that is incorrect information.

However, there is an important point.

⚠️ For people whose cheeks are already sunken,

Ulthera should not be performed.

Ulthera has specific areas

that should be treated.

If someone already lacks cheek volume,

a strong lifting treatment can make the face

look even more sunken.

An accurate diagnosis comes first.

✅ 10. What is the best way to use Ulthera?

These are the three key points

I emphasize.

① Combine lifting and volume treatment

While lifting with Ulthera,

areas that need volume should also be filled with fillers or similar treatments

to achieve natural results.

② Tip selection is important

Even with the same Ulthera,

the depth reached and the effect differ depending on which tip is used.

③ Clearly identify the area you want to improve

"If the goal is the jawline,

you shouldn’t lift the nasolabial folds instead."

Depending on the result you want,

the treatment area and method can be completely different.

Before your consultation, it is important to think clearly about

"What do I want to change?"

Hongdae Ulthera is not simply

a procedure that makes the face feel tighter.

Because it is a procedure that rebuilds

the structure inside the skin itself,

where and how it is used

completely changes the result.

If you have any questions,

feel free to ask anytime in the comments! 😊
