Hello, this is CELITA Clinic in Seomyeon, Busan. You may want to replenish your skin from within with a skin booster, yet hold back—"Won't all those needle passes hurt?" or "What if I'm left with marks the next day?" We completely understand that hesitation. X-Injector is an injection-assist device that delivers product at a consistent depth and volume while using cooling technology to lower perceived pain and reduce the product loss that seeps out (the loss rate), and it can be applied together with skin booster procedures.
In this article, we'll walk step by step through how X-Injector works, how it differs from other injection methods, what the procedure feels like and the downtime involved, who it suits and who it doesn't, and how we do things at CELITA Clinic in Seomyeon, Busan. Results and recovery responses vary from person to person depending on your skin condition, so we recommend deciding what's right for you together with our medical team during a pre-procedure consultation.
Have You Been Putting Off Skin Boosters Because You're Afraid of Needles?
In skin booster consultations, questions about pain and recovery often come up before questions about results. The wish to nourish the skin deep down is strong, but the thought of multiple needle passes—and the worry that redness or marks might linger into the next day—tends to push the decision back. If you have work or plans the very next day, you probably picture the recovery period before the procedure itself. X-Injector is a device built precisely to ease this burden, focusing on two things: pain management and injection precision.
How Does X-Injector Work?
X-Injector is a device that helps deliver product at a consistent depth and volume. Its operation can be broken down into three main parts.

First, AirON cooling. By rapidly circulating air inside the handpiece, it quickly lowers the temperature of the metal plate at the tip of the multi-needle, cooling the skin's surface just before injection. When the cold sensation registers first, the brain perceives the cooling ahead of the pain signal, which helps lower perceived pain.
Second, precise automated injection. Because the device senses the skin's resistance and thickness and delivers a set volume at a set depth, it can reduce the variation in injection depth and volume compared with injecting by hand.
Third, managing product loss (the loss rate). Some of the injected product can seep out to the skin's surface and be lost as the needle withdraws. X-Injector pairs smart-sensing, high-precision automated injection with a mechanism that contracts the entry point the moment the needle withdraws, designed to reduce how much product escapes to the surface. By delivering product evenly at a consistent depth within the skin, it helps the active ingredients absorb with less loss, and it lowers the degree of firm raised bumps that form. That said, the extent can vary somewhat depending on your skin condition and the product used alongside it.
Injection Methods at a Glance
Below is an informational comparison of injection methods and representative devices.
Category | Manual injection | Conventional multi-injectors (e.g., DermaShine Pro, Hycox) | Smart-sensing / cooling type (X-Injector) |
|---|---|---|---|
Injection method | Delivered directly by the practitioner | Multi-needle delivery using metered dosing and negative pressure | Automated delivery by sensing resistance and thickness |
Consistency of depth & volume | Varies with the practitioner's skill | Relatively consistent, mechanically | Delivered consistently based on sensor readings |
Pain management | Often no separate cooling | Cooling varies by model | Cooling is built in |
Product loss & raised bumps | Surface backflow can occur (varies by person) | Managed by a pressure/suction design | Designed to reduce backflow by contracting the entry point |
Downtime tendency | Varies by person | Varies by person | Varies by person |
It's hard to say that any one method is better in every case. The method that suits you depends on your skin condition, the product used alongside it, and the treatment area, so it's best decided together during a pre-procedure consultation.
When It's Not Recommended
If you are pregnant or breastfeeding
If there is active inflammation or infection at the intended treatment area (e.g., pustular acne, herpes)
If you are prone to keloids or hypertrophic scarring
If you have a bleeding disorder, are taking anticoagulants, or have an autoimmune condition that is not well controlled
If you have a history of hypersensitivity to specific ingredients, such as the skin booster product being co-injected
Even if one of the above applies to you, whether the procedure is possible can vary depending on your condition and timing, so final suitability is confirmed during a pre-procedure consultation with our medical team.
What Does the Procedure Feel Like, and What About Downtime?
During the procedure, many people feel a cool sensation along with a light pressing feeling. Perceived pain varies from person to person, so we adjust the intensity as we go, and topical numbing cream can be used as well if needed. The procedure time depends on the area and the type of skin booster being used.
Downtime is relatively short, and you can usually do gentle cleansing and wear makeup from the day after the procedure. That said, afterward you may notice raised bumps (where the injection sites temporarily puff up), bruising, swelling, mild redness, or some tenderness; most of this is temporary and subsides within a few days. Rarely, pigment changes or irritation can last longer, so if you notice any reaction that's different from usual, feel free to visit us to have it checked. Please keep in mind that we can't call it "pain-free," and that perceived pain and recovery speed differ from person to person.
Who We Recommend It For
If you want the benefits of a skin booster but are sensitive to needle pain
If you need to return to daily life right the next day and are concerned about recovery time
If you'd like the injection depth and volume to stay consistent across multiple sessions
If you want to reduce the loss of active ingredients seeping out to the surface
If you'd rather not have raised bumps or marks linger after the procedure
If any of these resonate with you, it may be a good fit. That said, final suitability is determined by checking your skin condition before the procedure.
Getting the Most Out of It
For about two weeks before the procedure, it's good to avoid heavy drinking, aggressive exfoliation, and irritating treatments, and to focus on moisturizing and sun protection. For about a week right after, avoiding saunas and jjimjilbangs (Korean spa houses), hot baths, intense exercise, and alcohol—while moisturizing often and applying sunscreen thoroughly when you go out—helps recovery. Start cleansing and makeup gently from the next day, but give scrubs and peels a rest for a while.
Changes in the skin often continue over the following one to three months. Since X-Injector is a device applied together with skin booster procedures, the specific number of sessions and the intervals between them are explained before the procedure, tailored to the product used and your skin condition.

Frequently Asked Questions
Is X-Injector a standalone procedure?
Rather than a standalone procedure on its own, X-Injector is an injection-assist device applied together with injection-based procedures like skin boosters. Which product to pair it with is decided together during a pre-procedure consultation, based on your skin condition and goals.
Does the procedure hurt a lot?
Perceived pain differs from person to person, and we work to ease the burden through cooling and intensity adjustment. If you tend to be sensitive to pain, topical numbing cream can be used as well, so please feel free to let us know during the pre-procedure consultation.
Can I go about my daily life right after the procedure?
Downtime is relatively short, and you can usually do gentle cleansing and wear makeup from the next day. That said, redness, raised bumps, or swelling may remain temporarily, so recovery speed varies from person to person.
How many sessions do I need?
The number of sessions and the intervals depend on the type of skin booster used and your skin condition. It's best to receive a plan suited to you during a pre-procedure consultation.
