If you were disappointed by the variation in results depending on the practitioner for Hycoox in Hongdae

September 11, 2026

Hello.

I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.

Have you ever felt disappointed because the results were different every time, even though you visited the same clinic and received the same procedure?

"I receive Juvelook and Rejuran regularly, but the condition of my skin feels a little different each time.

Since the ingredients and the clinic are the same, I wonder why these differences occur and if there is a way to get consistent results every time."

This is actually a question many people have.

It is reported that the consistency of skin booster results depends more on the precision of the injection than on the ingredients themselves.

Even with the same ingredients, the variation in results between sessions tends to be significant depending on how uniformly and accurately the substance is delivered to the target layer.

The approach of using the Hongdae Hi-Cooks system is to solve this variation problem through automation.

Today, I will explain the principles of how Hi-Cooks compensates for the limitations of manual procedures, why it is a KFDA-approved device with verified safety, and which skin booster treatments it can be used for.

What is Hongdae Hi-Cooks?

👉 Hongdae Hi-Cooks is an automated injector exclusively for skin boosters developed by NovaMedi.

It is a KFDA-approved medical device equipped with auto-sensing technology that detects the pressure the moment the needle touches the skin and automatically performs the injection.

Hi-Cooks is a Class 2 medical device approved by the Ministry of Food and Drug Safety (KFDA) for skin booster injection.

It is known as an option that increases the reproducibility of skin booster results by using an automated system to compensate for the precision deviations and ingredient loss that occur in traditional manual procedures.

At the Hongdae branch, we use the Hi-Cooks injector for various skin booster treatments, allowing you to access consistent results for representative skin boosters such as Juvelook, Rejuran, and Rejuran HB.

Technical Features of Hongdae Hi-Cooks

👉 Hongdae Hi-Cooks is an automated skin booster injection system that integrates three technologies into one device: auto-sensing detection, precise depth control, and an anti-leakage system.

Auto-Sensing Detection Technology

The tip of the Hi-Cooks needle is equipped with a pressure sensor.

Since the injection starts automatically when pressure is detected the moment the needle touches the skin, the practitioner does not need to manually adjust the pressure.

Thanks to this method, it is reported that stable injections are possible without the practitioner's manual dexterity variations affecting the results.

Precise Depth and Dosage Control

Hi-Cooks is a system that allows the practitioner to pre-set the needle's penetration depth and injection volume.

Because the skin thickness varies by area on the face—such as the forehead, cheeks, and eye area—each requires a different depth, and Hi-Cooks allows for precise adjustment for these specific areas.

It is known that using the dedicated 9-pin needle allows for simultaneous injection at multiple points, which also shortens the procedure time.

Anti-Leakage System

It is also equipped with technology to compensate for the drug loss that often occurs during manual procedures.

  • The structure is designed to minimize the backflow or leakage of ingredients to the epidermis when the needle is withdrawn, ensuring that the injected amount is accurately placed in the dermis.

Thanks to this system, it is reported as a strength that you can fully access the effects without losing expensive skin booster products.

Advantages of Hongdae Hi-Cooks

👉 Hongdae Hi-Cooks is an option that provides three advantages in one device: improved result consistency, reduced pain and bruising, and shortened procedure time.

Improved Result Consistency

If you felt that the results were different each time for the same procedure, it is generally known to be a problem of injection precision.

  • Because Hi-Cooks maintains the same depth, amount, and interval for every procedure through an automated system, it is reported that you can access care with low variation between sessions and high reproducibility.

Reduced Pain and Bruising

Manual procedures tend to accumulate irritation as the practitioner pierces the skin multiple times.

Since Hi-Cooks uses a method where precise injections are performed in a short time, the burden of irritation is relatively low, and it is known to have the characteristic of alleviating recovery burdens such as bruising or swelling.

Shortened Procedure Time

Because it is a system that injects into multiple points simultaneously with a dedicated 9-pin needle,

  • the procedure time is generally shorter than manual procedures.

It is used as an option that can be received without burden even during a busy schedule.

Skin Boosters Compatible with Hongdae Hi-Cooks

👉 Hongdae Hi-Cooks can be used for various types of skin boosters, and guidance on suitable areas and usage directions is provided according to the ingredients.

PN Series · Rejuran · Rejuran HB

These are skin boosters that induce self-regeneration by injecting salmon-derived PN ingredients into the dermis.

Rejuran HB contains hyaluronic acid and lidocaine, which relatively lowers the pain burden, so when combined with the precise injection of Hi-Cooks, comfortable and stable care is provided.

PDLLA Series · Juvelook

This is an option that induces self-collagen production with collagen booster ingredients.

  • Since Juvelook must be accurately placed in the dermis for uniform collagen stimulation, it is known that the Hi-Cooks precision injection system helps with result consistency.

Exosomes and Other Series

Stem cell-derived exosomes or other new skin booster ingredients can also be injected with Hi-Cooks.

The needle depth and injection pressure are adjusted according to the viscosity and characteristics of the ingredients,

  • and care is performed with settings suitable for each ingredient.

Who is Hongdae Hi-Cooks for?

Those who have received skin boosters multiple times but felt the results were different each time

Those who were dissatisfied with the pain or bruising of manual procedures

  • Those who want to receive expensive skin boosters accurately without loss

Those who want stable results through a regular management plan

Those who are planning skin booster treatments such as Juvelook, Rejuran, or Rejuran HB

Those who want to minimize downtime

⚠️ Precautions Before and After Hongdae Hi-Cooks Procedure

👉 Hongdae Hi-Cooks is a treatment where result consistency and recovery speed vary depending on pre-procedure condition management and post-procedure moisturizing and UV protection.

Side Effects of Hongdae Hi-Cooks and Things to Know in Advance

  • 👉 Although Hongdae Hi-Cooks is a KFDA-approved safety-verified device, initial reactions may vary depending on individual skin conditions and the skin booster ingredients used.

Immediately after the procedure, redness, micro-swelling, and temporary embossing marks may appear on the treated area.

Embossing is known as a natural sign that the ingredients have been accurately placed in the dermis,

and it usually clears up naturally within 1 to 3 days.

  • In the case of sensitive skin, micro-reactions may continue for a few days.

Hi-Cooks is an injection device, and the device itself has a low factor for causing side effects.

Since the main reactions depend on the skin booster ingredients used together,

the choice of ingredients is reviewed according to individual allergy history and constitution.

  • It takes several days to several weeks for skin booster ingredients to start reacting in the dermis,

so it is a treatment where results are established through cumulative sessions rather than a dramatic change from a single procedure.

Regular sessions are important for satisfaction with the results.

If any of the following apply to you, the procedure may be restricted or

prior confirmation may be required, so please inform us during the consultation.

  • If you are pregnant or breastfeeding

  • If there is an active infection, wound, or herpes in the treatment area

  • If you are regularly taking anticoagulants or antiplatelet agents, or have a bleeding tendency

  • If you have been diagnosed with an autoimmune disease or keloid constitution

  • If you have a history of allergies to the skin booster ingredients used (salmon, seafood, etc.)

  • If you have a history of lidocaine allergy (when using skin boosters containing lidocaine)

If you have a history of filler or thread procedures in the treatment area recently

❓ Frequently Asked Questions (FAQ)
