Cooling Low Pain X-Injector — PECHE Clinic, Gangnam Station

A motorized injection device that delivers injectable skin booster medication in set, even amounts, cooling the spot where the needles land to lower the felt pain · Right by Gangnam Station Exit 4

Cooling Low Pain X-Injector

The X-Injector isn't the name of a treatment — it's a motorized injection device used when placing injectable skin boosters. Its official device classification is "motorized medicinal injection pump," meaning a machine built to deliver medication in set amounts.

The device pushes out the set amount with the same force each time, handling the work of placing the medication across the whole face in equal amounts at closely spaced points.

Its other core feature is cooling. The plate the needles come through is chilled, so the needles enter after the cold has already dulled the sensation — this is the device's key mechanism for lowering the felt pain of injection.

What goes in (the medication) is set by the treatment you receive. The X-Injector's role is placing that medication evenly, and with less pain.

When It's Used

When medication needs to be spread evenly across a broad area, like the whole face
When the medication is thin and needs to be divided evenly
When a treatment calls for repeated placement at the same depth across many spots
When injection pain or small raised bumps at the injection points are a concern and you're looking for an add-on option

Which medications it's used for is decided by their properties — how thin they are and whether they contain particles. Some medications are better placed by hand, one point at a time, so the delivery method is decided from the assessment and the product's properties.

Cooling — the Cold Reaches You Before the Sting

The multi-needle plate the needles come through is kept cold, so the surface chills the instant the plate touches the skin. The needles enter in that state, and the cold holds while the medication goes in.

Cold and stinging travel along similar nerve pathways, so when the cold sensation takes its place first, the sting feels duller — the same reason a spot that's been chilled hurts less. How much less varies from person to person, so we don't promise it in numbers.

Close and Even — What This Device Handles

Machine delivery doesn't mean the medication goes in sparsely. The fine needles move across the skin at close intervals, laying the medication down as densely as if placed by hand, one point at a time.

What the machine adds is consistency. It's built to push the set amount with the same force, so that each spot is meant to receive the same amount.

A Design That Also Settles Concerns About Leakage

There's no need to worry that delivery by machine means the medication leaks out. The X-Injector holds the skin with a gentle suction, inserts the needles in that state, and withdraws them only after the set amount has gone in.

With the skin held in place, the needle holes are less likely to shift or open, so little of the intended medication leaks out and it settles inside the skin.

Dedicated Sterile Needles

The needles are a separate, single-use sterile injection-needle product (the multi-needle) fitted to the device. It takes the form of a plate carrying several very fine needles, and it's discarded after a single use.

Where It Fits in the Treatment

1. Assessment and treatment decision The skin booster treatment and the areas are decided.

2. Numbing cream Numbing cream is applied, followed by a wait; the waiting time is matched to the treatment you're receiving with it.

3. X-Injector delivery The medication syringe is mounted on the device, and the medication is placed in divided doses, area by area.

4. Soothing and guidance The recovery course and aftercare are explained according to the treatment received with it.

Expected Reactions and Possible Side Effects

What you'll feel during delivery: a cold sensation as the chilled plate touches first, a gentle pull as the skin is drawn in slightly, and a light, shallow sting as the fine needles land, like a stamp. How much you feel varies by medication, area, and person.

After treatment: the recovery course follows the skin booster treatment received with it, and we'll go over it with you. If anything lasts longer than expected or worsens, contact us and we'll check it with you.

How PECHE Clinic Does It

We sort out the right delivery method for the medication. An injector isn't a tool used the same way for every medication. Depending on the medication's properties — how thin it is and whether it contains particles — some suit motorized delivery and some suit placement by hand. What it's delivered with is decided from the product's properties and your assessment results.

The prep room is behind a glass wall, in full view. The preparation of the medication and needles is visible through the glass from the waiting area.

We don't promise results by a device's name. Results come from the medication delivered and your skin's condition; the device is the means of delivering it evenly. We explain what the device does and what the medication does, separately.

Pricing

The X-Injector isn't a treatment received on its own — it's a separate optional add-on not included in the base treatment price. The cost depends on the treatment received with it and the configuration, and we go over it at the consultation.

FAQ

Q1. Is the effect better when delivered with this device? A: The effect is set by the medication delivered and your skin's condition. The device is a means of delivery that divides the medication evenly in the set amounts, so results can't be promised by the device's name alone.

Q2. Which treatments is it used for? A: It can be used for injectable skin boosters that aren't highly viscous, such as Rejuran, Juvelook, Belotero Revive, NewArti, Laetigen, and Re2O. Whether it's actually used for the treatment you're receiving is decided by the product's properties and your assessment.

Q3. Are the needles reused? A: No. The needles are a single-use sterile injection-needle product supplied separately from the device.

Q4. What does it feel like? Is it less painful than a hand injection? A: It tends to be less painful, and the reason is cooling. With the chilled plate touching first and the skin already feeling cold, the skin is drawn in with a gentle pull and the fine needles land like a stamp — a light, shallow sting. How much you feel varies by medication, area, and person.

Q5. Who performs the treatment? A: PECHE physicians who all work to the same standards, built from over 90,000 documented treatments. The amount to deliver and how it's divided across areas are set not by feel but by your assessment results and these standards.
