How to Minimize Pain for Skin Booster Treatments in Uijeongbu Using the Hycoox Injector

April 16, 2026

Hello.

I am Dr. Hyuk-chan Cho, Director of Cleor Clinic Uijeongbu Branch.

"I'm looking into dermatological skin booster treatments,

but I'm so afraid of getting injections."

Since there are quite a few reviews about pain when searching online,

many people find it difficult to make a decision.

In fact, the stinging sensation of Uijeongbu skin boosters

is not a problem with the procedure itself.

Whether it's hyaluronic acid or Rejuran, for the active ingredients to be effective,

they must directly reach deep into the dermis layer, not just the skin surface.

The dermis is not a soft tissue like a sponge,

but a layer where collagen fibers are densely packed,

so it is natural to feel pressure when the needle passes throughit.

Therefore, to reduce this burden of pain

while accurately delivering the drug,

specialized injector devices have been developed.

Today, I will discuss what devices are available and how Cleor Clinic Uijeongbu Branch

approaches this procedure.

Reasons for using an injector instead of manual injections

There are two main methods for skin booster injection.

Manual injection, where medical staff directly control the needle to inject stitch by stitch,

and the injector method, where the device automatically adjusts the depth and dosage for injection.

Manual injection has the advantage of being able to apply treatment intensively

and precisely to the desired area.

An increasing number of people are choosing injectors because they can cover a wide area quickly and uniformly

while reducing the burden of pain.

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

Each has its pros and cons, so the more suitable method varies depending on

the skin condition and the type of drug.

Injector devices currently used in dermatology

To reduce the pain of Uijeongbu skin boosters,

there are three representative injector devices currently utilized in dermatology.

🔺Rejuemateis a multi-pin injector designed exclusively for skin boosters,

used to uniformly spread viscous drugs like Rejuran.

🔺DermaShine Prouses negative pressure, or suction, to slightly pull the skin

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

Because it injects while the skin is lifted,

the structure reduces drug loss and lowers pain.

🔺Hycoox Injectoris a multi-injector approved by the Ministry of Food and Drug Safety (KFDA)

in Korea,

equipped with both auto-sensing and vibration functions.

Cleor Clinic Uijeongbu Branch uses the Hycoox Injector

Among the three devices, the one utilized at Cleor Clinic Uijeongbu Branch

is the Hycoox Injector.

To explain the operation of Hycoox simply:

The moment the needle touches the skin, it senses the skin pressure itself

and automatically injects the drug according to that value.

It is not adjusted one by one by human hands,

but a method where the device operates by reacting to the skin condition.

A vibration function is added to this.

As the vibration stimulus is transmitted to the nerves before the pain signal,

it works on the principle of reducing the brain's perception of pain.

You can choose needle types from 3-pin, 5-pin, and 9-pin,

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

It also has a drug loss prevention function.

The structure minimizes the drug leaking out of the skin after injection,

so even with the same dosage, more active ingredients are delivered to the skin.

However, I must be honest about one thing.

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

and the drug may leak from the surface.

In such cases, we combine manual injections

or adjust the method according to the situation.

Skin booster treatments that work well with an injector

The scope of injector use varies depending on which drug it is used with.

Treatments performed with the Hycoox Injector

Here are the treatments utilized with the Hycoox Injector

at Cleor Clinic Uijeongbu Branch.

👉Rejuran Healerinjects PDRN and PN components extracted from salmon into the dermis layer

to induce skin regeneration and improve inner dryness.

As it is a procedure known for being quite painful,

using an injector helps reduce the burden.

👉Juvelookis a collagen booster that combines PLA microparticles and hyaluronic acid.

It is often chosen by those aiming to improve loss of elasticity and fine lines.

Since it is a viscous drug, pain can be felt strongly during manual injection,

but using an injector automatically adjusts the injection pressure,

helping to reduce perceived pain.

👉Mul-gwang Injection (Hyaluronic Acid)is a procedure that improves hydration by injecting hyaluronic acid,

which has moisture-attracting properties, into the dermis layer.

It has low viscosity, making it suitable for injector injection,

and can cover the entire face evenly and quickly.

👉 Exosomeis frequently used to improve sensitive or acne-prone skin

due to its cell regeneration and anti-inflammatory effects.

As a water-soluble component, it pairs well with an injector.

The suitability for an injector varies because each drug has different viscosity and characteristics.

Which drug is right for your current skin condition

will be guided after a direct assessment during the consultation.

⚠️Precautions

Even with the Uijeongbu skin booster injector method,

it is difficult to say it is completely painless.

Although numbing cream is applied before the procedure,

slight pressure or stinging may be felt during the treatment.

After the procedure, an 'embossing' effect where the injection sites

appear bumpy may occur.

This is a normal reaction when a viscous drug enters the dermis layer,

and most cases subside naturally within 2 to 3 days.

Bruising or swelling may occur and can last for 1 to 2 weeks depending on the individual.

Please be sure to use sunscreen from the day after the procedure,

and avoid saunas, alcohol, and strenuous exercise for a certain period.

This can be an option for the following people:

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

  • Those who want the drug delivered evenly across the entire face

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

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

However, for those with very thick skin or a history of allergies to specific ingredients,

a prior consultation is required first.

❓ Frequently Asked Questions

Q. Is it really less painful when injected with an injector?

Many people feel that the burden of pain is reduced compared to manual injections.

However, it is difficult to say it is completely painless.

While the vibration and auto-sensing functions work to lower perceived pain,

there are differences depending on individual skin sensitivity.

If you are very concerned about pain, please let us know in advance, and we will adjust accordingly.

Q. How many sessions of Uijeongbu skin booster should I receive?

While some people notice changes after a single session,

for the effects to accumulate and last longer,

it is common to receive 3 or more sessions at 1-month intervals.

Subsequent maintenance is recommended once every 3 to 6 months.

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

it is best to establish a plan after a consultation.

Q. Which skin booster drug should I choose?

If the goal is inner dryness and skin regeneration, Rejuran is often chosen;

if the goal is collagen regeneration and elasticity improvement, Juvelook;

and for overall hydration, hyaluronic acid-based Mul-gwang injections are frequently selected.

We will guide you to the appropriate drug after directly assessing your skin condition.

Q. When does the embossing effect disappear?

Most cases subside naturally within 2 to 3 days.

If you have an important schedule, it is recommended to receive the treatment at least one week in advance.

Q. Is the Hycoox Injector suitable for all skin types?

For those with thick skin, the drug may not be delivered to the desired depth

and may leak out.

In such cases, we combine manual injections or adjust the method.

The suitable method is determined after directly checking the skin during the consultation.

If you are considering Uijeongbu skin boosters,

which drug is injected and how it is injected affects the results.

At Cleor Clinic Uijeongbu Branch,

we design treatments using the Hycoox Injector to reduce the burden of pain

and increase drug delivery efficiency.

Even when using the same device, the choice of drug and application method varies

depending on the skin condition and goals,

so we directly assess each visitor's skin and provide customized guidance.
