Mugyo-dong Dermatology: Lip Filler Before-and-After Review, Pain, and More — Organized in Q&A image 1

Hello.

This is Woo Young-jin from Beautyst Doctors.

When consulting about lip filler at a Mugyo-dong dermatology clinic,

I receive many different questions,

from product selection and volume to pain and side effects.

“Which lip filler product is best?”

“Is 1cc enough?”

“Is there a risk of side effects?”

“Does it still work as you get older?”

Lip filler is not simply a procedure that adds volume.

It is closer to a design procedure that requires consideration of

lip shape and proportions,

as well as the overall balance of the face.

That is why product selection,

volume, injection location, and ratio design

have a major impact on the result.

I will organize everything about lip filler one by one,

based on the treatment room standards of a Mugyo-dong dermatology clinic.

  1. Which lip filler product is best?

The product selected for lip filler

depends on the desired result.

If you want to make the lip line look more defined,

a slightly firmer filler is suitable,

and if you want to naturally increase the overall volume of the lips,

a softer filler is suitable.

A product that can express both of these

is Restylane Kysse, a lip-specific filler.

Because it is soft yet maintains its shape,

it can help with both refining the lip line and naturally increasing volume.

This is why Mugyo-dong dermatology clinics also

use this kind of lip-specific filler often

for natural lip design.

  1. How painful is lip filler?

Because the lips are an area with many nerves,

many people worry about pain.

Usually, if cream anesthesia or nerve anesthesia is performed,

the pain is not severe.

It is often felt as a slight sting,

and the intensity can be adjusted during the procedure as well.

At a Mugyo-dong dermatology clinic,

the procedure is carried out in a way that minimizes pain,

taking the characteristics of the lip area into account.

  1. Can lip filler cause side effects?

The 대표적인 side effect of lip filler is injection into a blood vessel.

If a blood vessel becomes blocked, there is a risk of skin necrosis.

However, understanding the location of the lip blood vessels,

injecting into a superficial layer, and distributing small amounts of filler

If these principles are followed,

the risk is lowered.

It is important to understand the anatomical structure

and proceed slowly.

  1. How many cc of lip filler are needed?

For natural-looking lip filler,

about 1cc is usually enough.

If the lips are very thin

or you want to emphasize volume,

it may be done with 1.5cc or even 2cc.

However, instead of starting with a large amount,

it is important to create a natural balance

with 1cc.

In consultations at a Mugyo-dong dermatology clinic as well,

when a natural change is desired,

it is often designed around 1cc.

  1. What should the upper and lower lip ratio be?

The lip ratio should be considered together

with the overall balance of the face.

In general,

a ratio of upper lip 2 : lower lip 3

looks natural.

However, adjustments are needed depending on

chin length, how protruded the mouth is,

and the distance between the nose and lips.

That is why it is important to look not only at the lips,

but also at the overall facial balance.

  1. Is there no risk of blood vessel blockage from filler?

The possibility is very low,

but it does exist in theory.

That is why during the procedure,

small-volume injection, distributed injection, and consideration of blood vessel location

are performed.

This approach helps minimize the risk.

  1. Can lip necrosis occur?

If a blood vessel becomes blocked,

there is a possibility of necrosis.

However, accurate layer placement, proceeding slowly,

and anatomical understanding

are the three important factors.

Depending on the procedure method,

the risk can be greatly reduced.

  1. Does it work if the mouth is protruded?

If the mouth is protruded,

lip filler should be performed carefully.

That is because adding volume may make

the mouth appear even more protruded.

In such cases, the chin line, corners of the mouth, and facial contour

must be considered together.

  1. Why do lips become smaller with age?

As we age, collagen decreases,

e elasticity decreases, and volume decreases.

The lips are an area where collagen loss

appears relatively quickly.

That is why the lips become thinner,

the corners of the mouth droop,

and the mouth appears more pursed.

In this case, lip filler can be a way

to naturally restore volume.

At a Mugyo-dong dermatology clinic as well,

lip filler for people in their 50s and 60s

is often discussed as a procedure that

naturally improves the impression of the face.

Lip filler is a procedure whose results vary

depending on product selection and volume design.

If the 기준 is natural volume,

about 1cc can usually produce

a sufficient change.

In addition, the lip ratio is generally

most natural when the upper and lower lips are set around 2:3,

but adjustments may be needed depending on

the individual’s facial proportions and lip thickness.

In particular, because the lip area has

a rich distribution of blood vessels,

in order to reduce side effects,

procedures that take the anatomical structure into account

are important.

Also, as people get older,

collagen and volume in the lips decrease,

making the lips look thinner and smaller,

so many people feel the effect of

naturally restoring volume through lip filler

more clearly.

If you are considering lip filler,

rather than simply increasing volume,

it is better to proceed with a customized design

based on the current lip thickness and facial balance.

If you have any more questions,

please leave them in the comments,

and I will provide detailed guidance

based on the treatment standards of a Mugyo-dong dermatology clinic.

Thank you for reading.
