What is the X-Injector and why is it used in skin booster treatments?
The X-Injector is an automatic injection assist device used to inject skin boosters such as Rejuran, Retuo, and hydrating injections into the dermis layer of the skin. While the type of product used for skin boosters is important, it is also crucial to consider how evenly and to what depth the medication is delivered.

Regular injections involve the medical staff manually moving the needle to inject the medication, whereas the X-Injector automatically injects the medication using multiple fine needles at a set depth, volume, and speed.
This helps ensure that the medication is delivered evenly and enhances the uniformity of the injection process.
However, using the X-Injector does not inherently increase the effectiveness of the skin booster. The X-Injector is a device that assists in the delivery of the medication, and the skin improvement effects depend on the characteristics of the skin booster product used, the individual's skin condition, and the purpose of the treatment.
Therefore, it is advisable to understand the role of the device itself and the effects of the skin booster product separately.
How does the X-Injector reduce pain discomfort?
The X-Injector uses a multi-needle method where 9 fine needles enter the skin simultaneously.

Designed for multiple needles to enter simultaneously, it differs from the sequential entry of one needle at a time. Additionally, it is designed so that the stimulation from multiple needles feels like a single stimulus, which can help reduce the pain discomfort experienced during the procedure.
However, having multiple needles does not mean that there will be no pain at all. The degree of discomfort can vary depending on skin sensitivity, the treatment area, the amount injected, and individual pain sensitivity.
Therefore, it is better to understand the X-Injector as a device that can help alleviate the burden of discomfort during the injection process rather than a device that eliminates pain.
What role does the AirON cooling technology of the X-Injector play in reducing injection pain?
The X-Injector not only has a needle injection method but also incorporates AirON technology that cools the skin surface.
Just before the procedure, a metal plate is rapidly cooled and then brought into contact with the skin surface, which can help temporarily dull the sensation of the skin surface through cold stimulation, thereby reducing the prickling and discomfort felt during the injection.
In other words, while the 9 multi-needles use a simultaneous injection method, AirON is a cooling method that considers the sensation of the skin surface. The combination of these two features can help reduce the burden of pain during the procedure, but it does not completely eliminate pain.
If you are usually sensitive to injection pain or have significant concerns about pain, it is advisable to consult with the medical staff before the procedure to see if the use of numbing cream can be considered.
What are the differences between the X-Injector and regular injections?
Regular injections involve the medical staff manually moving the needle to adjust the depth and volume of the injection, which allows for precise control of the injection process based on the skin area and condition.

In contrast, the X-Injector automatically injects the medication according to the set depth, volume, and speed, which can help maintain a consistent injection process. Additionally, it is designed so that the entry point of the injection site constricts when the needle exits the skin, which can help reduce the phenomenon of medication backflow to the skin surface and embossing.
The two methods differ in the process of delivering the medication and the adjustment methods, and it is not necessarily the case that one method is more suitable for all areas. The cooling function and automatic injection method of the X-Injector can help reduce the burden of pain during the procedure, but the actual level of pain can vary depending on the treatment area, skin condition, and individual pain sensitivity. In cases where delicate adjustments are needed for specific areas, the medical staff may decide to use regular injections or combine both methods.
Ultimately, it is important to choose the appropriate injection method based on the product used, treatment area, and skin condition.
Can embossing, swelling, or bruising occur after X-Injector treatment?
The X-Injector can help reduce pain discomfort during the procedure and minimize medication backflow or embossing through its cooling and automatic injection methods, but it does not eliminate all post-treatment reactions.
During the process of the needle entering the skin, there may be sensations of prickling or pain, and after the procedure, the skin may temporarily redden, swell, and show embossing or bruising at the injection site. These reactions can vary depending on the skin booster product used, the amount injected, the treatment area, and the individual's skin condition.
Most daily activities are possible, but temporary redness, swelling, or bruising may occur, so it is advisable to plan the timing of the procedure with some leeway if there are important events.
Using the X-Injector does not guarantee that pain, swelling, or bruising will not occur, so it is advisable to thoroughly check the expected reactions and recovery process before the procedure.
How does AMRED Clinic utilize the X-Injector in skin booster treatments?
At AMRED Clinic, the X-Injector is utilized as one of the injection methods applicable to skin booster treatments rather than as a standalone procedure.

Since products like Rejuran, Retuo, and hydrating injections have different characteristics and treatment purposes, it is important to consider what skin concerns you want to improve and what your current skin condition is. After that, you can choose the appropriate injection method based on the product used, treatment purpose, and treatment area.
Especially for those who have concerns about injection pain or are considering a different injection method than regular injections, utilizing the multi-needles and cooling technology of the X-Injector can be an option. Conversely, if delicate adjustments are needed for specific areas, the medical staff may consider using regular injection methods based on their judgment. The key is not to use a specific device but to choose the product and injection method that suit the individual's skin condition and treatment goals.
