Question 1

Once I’ve had LINE ON Injection, can the fat come back?

오해석 · Accepted Answer

The most common misconception is that a single session will stop you from gaining weight again. There’s a limit to how much fat one session can reduce, so at most it refines a contour.

Question 2

Does LINE ON Injection contain steroids?

오해석 · Accepted Answer

No. Steroids can produce an effect by shrinking tissue, but they can cause side effects throughout the body, including irregular periods and bleeding between periods, so I don’t use them.

Question 3

If there’s no set dose limit, how much LINE ON Injection do you actually use?

오해석 · Accepted Answer

I inject the amount that gives the greatest effect in each area. How much that is depends on your body weight, the thickness of the fat under your skin and the skin elasticity in that area.

Question 4

Will the treatment still work if I don’t exercise or watch my diet?

오해석 · Accepted Answer

It may still have an effect, but without exercise and a healthy diet, the change soon wears off.

Question 5

What does it mean to inject precisely into the fat layer?

오해석 · Accepted Answer

Even within the fat under the skin, there are deep, middle and shallow layers. Injecting precisely means telling these layers apart in each area and injecting at the depth where the treatment works best.

Question 6

What does the 15-minute microwave treatment do?

오해석 · Accepted Answer

The microwave treatment works on two layers: it destroys fat in the fat layer and improves elasticity in the dermis, the deeper layer of the skin. Used together with LINE ON Injection, each enhances the effect of the other.

Question 7

If there’s no set dose limit, how much LINE ON Injection is too much?

오해석 · Accepted Answer

Because of how the LINE ON Injection solution is formulated, the dose isn’t limited by body weight. But injecting too much puts excess pressure on the skin, and recovery can take longer with little gain in effect.

Question 8

What are the most common misconceptions about 3cc Face LINE ON?

오해석 · Accepted Answer

Two worries come up most: that the filler will slide down, and that it can’t be removed later without being scraped out.

Question 9

Is 3 mL of filler really enough?

오해석 · Accepted Answer

For most people, yes. The aim isn’t to add volume and make the face bigger, but to reinforce the areas where the face lacks structural support.

Question 10

Can filler cause an allergic reaction?

오해석 · Accepted Answer

Rarely, yes. Because filler isn’t your own tissue, it can occasionally cause an allergic or hypersensitivity reaction. If that happens, we dissolve the filler with an enzyme injection (hyaluronidase) so your body can absorb it.

Question 11

How do you decide where to put filler on my face and how much?

오해석 · Accepted Answer

Faces vary too much from person to person to fit a single formula. I look at your face to see where structural support is lacking, then set priorities within the fixed amount of filler.

Question 12

Why use 3 mL of filler in total instead of treating each area separately?

오해석 · Accepted Answer

Because a face is about the balance of the whole, not about individual parts.

Question 13

What’s the difference between Korean-made and imported fillers?

오해석 · Accepted Answer

It’s less about Korean-made versus imported than about the manufacturer. Each company has its own way of producing hyaluronic acid and of treating the cross-linking agent, which affects how much of it remains after the final washing. Each also has its own processes, standards and specifications for the filler’s physical properties.

Question 14

Do the areas that need filler change with age?

오해석 · Accepted Answer

Yes. With age, facial bone is resorbed, the deep fat under the skin decreases, the skin loses elasticity and the shallow fat sags, and the muscles weaken. Together, these turn the “inverted triangle” of a young face, fuller at the cheeks and narrower at the jaw, into a triangle.

Question 15

What are the most common misconceptions about Nose LINE ON?

오해석 · Accepted Answer

One is that the threads never dissolve. The other is a pair of opposite beliefs: that the effect lasts more than a year, or that it doesn’t even last a month.

Question 16

Will nose threads cause problems if I want nose surgery later?

오해석 · Accepted Answer

Compared with a nose that has never been treated, surgery involves one extra step, so it can be slightly more work for the surgeon. But it won’t stop you from having surgery or make the result worse.

Question 17

Can I get Nose LINE ON if I’m thinking about nose surgery later?

오해석 · Accepted Answer

If you’re already considering surgery, I recommend having surgery from the start.

Question 18

Is LSCO a thread or a filler?

오해석 · Accepted Answer

LSCO is a thread: an L-shaped lifting suture made for shaping the nose. Nose LINE ON uses LSCO together with filler to refine the shape of the nose without surgery.

Question 19

How is Nose LINE ON different from a regular nose thread lift or nose filler?

오해석 · Accepted Answer

A thread behaves more like a solid, while filler is more like a gel that can flow. Threads are better for firmly lifting the nasal tip, and filler is better for creating fine detail in the shape.

Question 20

How does the L-shaped nose thread avoid poking through the skin, and why does it last longer?

오해석 · Accepted Answer

Because I designed it so that the nasal tip rests on a broad surface, where the thread folds into an L, rather than on the sharp end of a thread.

Question 21

How much can you change a nose without surgery?

오해석 · Accepted Answer

A change of up to 20% from your nose’s current shape is well within what non-surgical treatment can do. If you want a bigger change than that, I recommend surgery.

Question 22

What are the most common misconceptions about breast fat transfer?

오해석 · Accepted Answer

The most common worry is that it will cause calcification or oil cysts. These are indeed the best-known complications of fat transfer. But when an appropriate amount of fat is transferred, within a range that doesn’t raise the risk, not every fat transfer leads to oil cysts and calcification.

Question 23

How much of the transferred fat stays after breast fat transfer?

오해석 · Accepted Answer

Published studies put the fat retention rate at about 50%. It can drop to about 30% if you lose weight, and it can rise to as much as 70% if you gain weight.

Question 24

Breast implants or fat transfer: which is right for me?

오해석 · Accepted Answer

If you want to go up three or more cup sizes at once, implants are the right choice. If you want a change of about one to one and a half cup sizes, fat transfer can achieve that.

Question 25

Where do you take the fat from?

오해석 · Accepted Answer

Breast fat transfer needs about 400–500 mL of pure fat after processing. It’s usually taken from the thighs, abdomen and love handles.

Question 26

What are the most common misconceptions about Lower Body LINE ON?

오해석 · Accepted Answer

The most common misconception is that what’s added will slide down. Transferred fat doesn’t slide down.

Question 27

How long does transferred fat last once it has taken?

오해석 · Accepted Answer

As long as you don’t lose weight, you can expect fat that has taken to stay largely as it is, just like the rest of your own fat.

Question 28

For hip dips and buttocks, is filler or fat transfer better?

오해석 · Accepted Answer

Hip dips are an area that naturally has little fat. In some people the tissue there has room to spare; in others it is very tight. The tighter it is, the less of the transferred fat takes.

Question 29

Why does Lower Body LINE ON treat the thighs, buttocks and love handles together?

오해석 · Accepted Answer

If you only treat the thighs, only the thighs improve; if you only treat the waist, only the waist gets slimmer. What matters is one continuous line running through the thighs, buttocks and love handles.

Question 30

How do you decide between liposuction alone and adding fat transfer to the buttocks?

오해석 · Accepted Answer

If your buttocks are already full, slimming just the thighs can make them look bigger, so liposuction alone may be enough to bring out the line. If you have hip dips, or your hips or buttocks themselves lack volume, liposuction alone may not be enough.

Question 31

What’s the difference between the EVA device and Lipokit for processing fat?

오해석 · Accepted Answer

When harvested fat is spun in a centrifuge, it separates into blood, pure fat and a layer of oil. Only the pure fat is transferred, so how cleanly the oil layer is separated out matters a great deal.

Question 32

How much fat can be removed with liposuction in one session?

오해석 · Accepted Answer

There’s no fixed upper limit. It depends on your body weight, how much tumescent solution (a saline-based fluid) is injected into the fat under the skin, and how much blood comes out with the removed fat.

Question 33

What should I expect with compression garments, swelling and bruising after liposuction?

오해석 · Accepted Answer

Generally, most of the swelling goes down in about 1 month, and the rest in about 3 months. Bruising mostly fades within 2 weeks.

Question 34

Are there times you advise against treatment?

오해석 · Accepted Answer

Yes. I believe whether a treatment is technically possible and whether it’s worth doing for that person are two completely different questions.

Question 35

Is filler still a good choice these days?

오해석 · Accepted Answer

If you want to improve volume, filler is still a good choice. In fact, I think filler is underrated.

Question 36

How do you assess a person’s natural lines?

오해석 · Accepted Answer

Whether it’s the face or the body, I look at the flow and proportions that connect one area to the next, not at a single area. That’s because no single line suits everyone.

Question 37

Can I see you if I’m having problems after treatment at another clinic?

오해석 · Accepted Answer

Yes. For people who want to regain lines they’ve lost, whether after a first surgery or a revision, we’re also planning to offer corrective care after surgery.

Question 38

Is Renuvion a laser or radiofrequency?

오해석 · Accepted Answer

It uses radiofrequency energy, but it’s different from radiofrequency lifting applied to the skin surface. A thin handpiece goes under the skin, and plasma created at its tip heats the fibrous tissue directly.

Question 39

Why does Renuvion use helium gas?

오해석 · Accepted Answer

Helium is a light gas that doesn’t react with substances in the body. With radiofrequency energy, only a tiny part of it turns into plasma, giving fine, even heat to a small area for a very short time.

Question 40

If Renuvion heats the tissue under the skin to 85°C, can it cause burns?

오해석 · Accepted Answer

The fibrous tissue under the skin reaches about 85°C, but only very briefly, so the skin surface stays below 41°C. Burns are still possible with any heat-based treatment, so we watch your skin and adjust the energy and number of passes as we go.

Question 41

Is one Renuvion treatment enough, or will I need several?

오해석 · Accepted Answer

In most cases, we plan for one treatment. The fibrous tissue under the skin contracts right after treatment, then new collagen forms over the following months as the shape settles. We assess the result at about 6 months.

Question 42

When is Renuvion not enough?

오해석 · Accepted Answer

If there is a lot of loose skin that forms a large fold when pinched, Renuvion alone may not be enough. Surgery to remove the excess skin may suit you better, and we’ll tell you honestly after examining you.

Question 43

Can Renuvion help with a loose belly after pregnancy?

오해석 · Accepted Answer

If there’s remaining fat and the skin is only mildly loose, Renuvion can be combined with abdominal liposuction. If your abdominal muscles have separated or there’s enough excess skin to form folds, Renuvion alone is unlikely to be enough.

Question 44

Can I have Renuvion on its own?

오해석 · Accepted Answer

If you don’t have much fat and only the skin is loose, Renuvion can be done on its own, heating under the skin through one small entry point for the handpiece. If there’s fat too, combining it with liposuction tends to give a better result.

Question 45

Is it normal for the area to feel hard after Renuvion?

오해석 · Accepted Answer

Yes, it’s a common reaction. As the heated tissue contracts and heals, the area may feel firm or itchy for a few weeks to a few months, and it softens over time.

Question 46

Can I tell in advance whether my skin will sag after liposuction?

오해석 · Accepted Answer

To some extent, yes, at an examination. We look at how quickly your skin springs back after a pinch, stretch marks, your age and how much fat is to be removed. If sagging seems likely, we’ll discuss adding Renuvion.

Question 47

Which areas of the face can be treated with Renuvion?

오해석 · Accepted Answer

At LINE ON Clinic, we treat under the chin, the neck and the jawline. This is because the use Renuvion received US FDA 510(k) clearance for in 2022 is improving the appearance of loose skin in the neck and under the chin.

Question 48

When will I see results from LINE ON Injection, and how many sessions do I need?

오해석 · Accepted Answer

You start to see a change the day after, once the swelling goes down, and it becomes clearer over 1–2 weeks. We usually recommend 3 sessions, 1 month apart.

Question 49

How long does 3cc Face LINE ON last?

오해석 · Accepted Answer

It varies from person to person, but we generally expect it to last about 1–2 years. You can see the change right after treatment, and there may be slight swelling for 2–3 days.

Question 50

How long do the results of Nose LINE ON last?

오해석 · Accepted Answer

Usually about 6–12 months, and longer for some people. The nose looks highest right after treatment, then settles gradually over a few months.

Question 51

When can I get back to my normal routine after Nose LINE ON?

오해석 · Accepted Answer

From the same day. But for 1–2 weeks, until the threads settle, avoid facial expressions that scrunch your nose, and avoid alcohol for one week.

Question 52

What is recovery like after breast fat transfer?

오해석 · Accepted Answer

The breasts themselves hardly hurt; the areas where fat was taken may ache like sore muscles for 1–2 weeks. You can return to daily life the next day, but take care not to put pressure on the breasts for a month.

Question 53

What should I be careful about after Lower Body LINE ON?

오해석 · Accepted Answer

You can return to daily life the next day. But for a month, avoid pressure on the buttocks and hip dips, and avoid alcohol and smoking.

Question 54

If I want another fat transfer, when can I have it?

오해석 · Accepted Answer

We recommend waiting at least 3–6 months, because it takes about 3 months to see how much of the transferred fat has stayed.

Question 55

Which is right for me: LINE ON Injection, Mini LINE ON Lipo or liposuction?

오해석 · Accepted Answer

We choose by looking at recovery time, how much change you want and your budget together. Going from LINE ON Injection to Mini LINE ON Lipo to liposuction, the change gets bigger, and so do the recovery time and the cost.

Question 56

How is Mini LINE ON Lipo different from liposuction?

오해석 · Accepted Answer

Both remove fat directly. But Mini LINE ON Lipo doesn’t remove fat from the whole area; it focuses on the one spot that bothers you and blends it with the surrounding area.

Question 57

I’m coming from outside Seoul. Can I go home on the day of surgery?

오해석 · Accepted Answer

Yes. All surgery is done as a day procedure, and you can usually leave within 2–3 hours afterwards. You can go home the same day, or stay overnight and go home after a check the next day.
