Gangnam Skin Booster: Is it different when using the Hycoox Injector for pain relief?

April 16, 2026

Hello!

I am Director Bo-hwang Jeong of Cleor Clinic Gangnam.

"I want to get a skin booster, but I heard it's too painful."

This is a phrase I hear very often in the consultation room.

Many people stop after reading reviews about the pain,

and there are more people than you might think who eventually give up on making a reservation.

I fully understand that feeling.

In fact, there is a reason why skin boosters are painful.

Whether it is hyaluronic acid or Rejuran, the drug is not applied to the skin surface,

but must be injected directly deep into the dermal layer for the effects to appear.

The dermis is a dense tissue where collagen is tightly intertwined,

so pressure is inevitable when the needle enters.

This is why some sensation is felt even after applying numbing cream.

Therefore, recently,to reduce the burden of pain,

specialized injector devices have been developed and are widely used in dermatology clinics.

Today, I will explain what kind of equipment is available,

what we use at Cleor Clinic Gangnam,

and focus on Gangnam skin booster pain relief methods as if we were in a consultation.

Why are skin boosters painful?

Skin boosters are procedures that directly inject active ingredients such as hyaluronic acid, Rejuran, and Juvelook

into the dermal layer of the skin.

The dermis is a dense tissue where collagen and elastin are tightly intertwined,

so pressure and pain occur when the needle enters.

It is true that some sensation is felt even with numbing cream,

and this is not a problem with the procedure method, but due to the characteristics of the dermal tissue.

Therefore, to alleviate Gangnam skin booster pain,

specialized injector devices have been developed and are being actively utilized.

What types of pain-reducing injector devices are there?

Skin booster injection methods are largely divided into hand injections and injector machines.

Hand injection is a method where the medical staff delicately injects point by point,

offering the advantage of intensive application to desired areas.

On the other hand, injectors are often chosen because the device automatically adjusts the depth and volume

for injection, resulting in shorter procedure times and reduced pain.

The difference in effectiveness between the two methods is not significant,

and since each has its pros and cons, the choice is made based on skin condition and goals.

There are currently three main types of specialized injector devices

used in dermatology clinics for Gangnam skin booster pain relief.

  • First, DermaShine Pro

It uses negative pressure, or suction, to slightly pull the skin

and injects the drug with a very thin 32G needle.

It operates with an auto-sensing method and is characterized by pain reduction

and minimization of drug loss.

  • Second, Rejumate

A multi-pin injector designed specifically for skin boosters,

it can cover a wide area quickly.

  • Third, Hycoox Injector

A multi-injector approved by the Ministry of Food and Drug Safety (KFDA),

it is equipped with both auto-sensing functions

and a vibration system.

These three devices commonly aim to reduce the burden of pain

and deliver the drug uniformly compared to hand injections.

Rather than one device being superior, each has different methods and characteristics,

and the appropriate device varies depending on the viscosity of the drug and the skin condition.

At Cleor Clinic Gangnam, we utilize the

during skin booster procedures.Hycoox Injector.

The core of Hycoox is Auto-Sensing

👉It automatically detects skin pressure the moment the needle touches the skin

and injects the drug accordingly.

It is not just mechanical injection,

but a method that responds and adjusts to the skin condition.

To use an analogy, it's not like pushing it in by hand,

but like a valve that opens automatically when the skin is ready.

A vibration function is added to this.

The principle is that vibration stimuli reach the nerves before pain signals,

reducing the perceived pain.

Various needle types such as 3-pin, 5-pin, and 9-pin can be selected,

allowing for different combinations depending on the area and drug characteristics.

Additionally, a built-in anti-leakage system minimizes drug loss.

Even with the same dosage, if loss is reduced,

more active ingredients are delivered to the skin.

However, I must be honest about one thing.

The injector method has the disadvantage that for those with thick skin,

the drug may not enter well and might leak.

Therefore, we do not recommend only the injector for everyone,

and we may combine it with hand injections or use different methods

depending on skin thickness and the type of drug.

🧐 Procedures that are better when using an injector

Injectors cannot be used for all skin boosters.

There are specific procedures that pair well with injectors depending on the viscosity and properties of the drug.

Below are representative procedures used with the Hycoox Injector

at Cleor Clinic Gangnam.

  • Rejuran Healer (Salmon Injection)

This procedure injects PDRN/PN ingredients extracted from salmon into the dermal layer.

It is mainly used for skin regeneration and improving inner dryness, but it is originally

known as a highly painful procedure.

It has appropriate viscosity for injector use,

and pairs well with injectors as it can cover a wide area uniformly.

Injector use is considered when you want to deliver it evenly to the dermal layer while reducing the burden of pain.

  • Juvelook (Collagen Booster)

A procedure that induces collagen regeneration using a combination of PLA microparticles and hyaluronic acid.

It is often chosen for the purpose of improving loss of elasticity and fine lines.

Since it has some viscosity, some people feel intense pain

when receiving hand injections.

Using an injector helps reduce perceived pain as the injection speed and pressure

are automatically adjusted.

Hydro-Lifting Injection (Hyaluronic Acid)

  • A procedure that injects hyaluronic acid into the dermal layer to attract moisture

and improve hydration.

It is easy to inject with an injector due to its low viscosity,

and can be applied evenly across the entire face.

Because the treatment area is wide, hand injections take time and lead to accumulated pain,

but using an injector can shorten the procedure time and reduce the burden of pain.

Exosome

  • A procedure that injects exosomes, which are intercellular signal transmitters, into the dermal layer

to induce skin regeneration and anti-inflammatory effects.

It is widely used to improve acne-prone or sensitive skin.

It is suitable for injector injection due to its low viscosity,

and can be delivered uniformly over a wide area while minimizing downtime.

To be honest, the injector method also has limitations.

For those with thick skin, the needle may not reach the desired depth,

and the drug may leak from the surface.

Also, 👉

hand injections are more suitable when the drug needs to beplaced precisely and intensively in a specific area.

In such cases, we may combine hand injections and injectors

or proceed with hand injections only.

The appropriate method is decided after checking skin thickness, drug type,

and the target area.

⚠️

Precautions Things you must know before the procedure

Using a Gangnam skin booster pain relief injector

does not mean it is completely painless.

Although it is performed after applying numbing cream, a slight pressure

or stinging sensation may be felt during the procedure.

After the procedure, bumpy 'embossing' may occur at the injection site,

which is a normal reaction when viscous drugs enter the dermal layer,

and it usually subsides within 2 to 3 days.

Swelling or bruising may occur and may last for 1 to 2 weeks

depending on the individual.

It is best to avoid saunas, strenuous exercise, and alcohol for a certain period after the procedure,

and please be sure to use sunscreen starting from the very next day.

This may be suitable for the following people:

Those who have been postponing skin boosters due to fear of injection pain

  • Those who want to receive the drug uniformly over a wide area

  • Those who want to address inner dryness or loss of elasticity from within the skin

  • Those who need to return to daily life immediately after the procedure

  • However, a prior consultation is essential for those with very thick skin

or a history of allergies to specific ingredients.

Frequently Asked Questions Q. Which is more effective, hand injection or injector?

The difference in effectiveness between the two methods is not significant.

Hand injection has the advantage of intensive and precise application

to desired areas, while the injector has the advantage of

covering a wide area evenly and quickly.

The appropriate method varies depending on skin condition and goals, so we will guide you during the consultation.

Q. How effective is the Gangnam skin booster pain relief?

There are differences depending on individual pain sensitivity.

Many people feel that the burden of pain is reduced when using an injector compared to hand injections,

but it is difficult to say it is completely painless.

If you are very concerned about pain, we can coordinate the anesthesia method during the consultation.

Q. How many sessions are needed to see results?

Some people feel a change after just one session,

but for cumulative and long-lasting effects, it is common to receive

3 or more sessions at 1-month intervals.

Afterward, maintenance is recommended once every 3 to 6 months.

Since it varies depending on the drug used and individual skin condition,

it is best to establish a plan after a consultation.

Q. Does the embossing last long?

When a viscous drug is injected into the dermal layer, bumpy

embossing may occur.

Most cases subside naturally within 2 to 3 days,

so if you have an important schedule, we recommend receiving the procedure at least one week in advance.

Q. Which skin booster drug should I use?

If the goal is inner dryness and skin regeneration, Rejuran is often chosen; if it's collagen regeneration and

elasticity, Juvelook; and if it's overall hydration,

hyaluronic acid-based Hydro-Lifting injections are often selected.

We will guide you on the appropriate drug and treatment plan after directly checking your skin condition.

If you want Gangnam skin booster pain relief,

the injector method can be one option.

Cleor Clinic Gangnam uses the Hycoox Injector

to deliver drugs uniformly and accurately,

and designs the procedure by combining it with hand injections or varying the drug combination

depending on the skin condition.

At Cleor Clinic Gangnam,

we do not apply the same method to everyone.

If you first tell us what your current skin concerns are,

we will honestly guide you in the right direction.
