Let us be real. Everyone knows Rejuran Healer works wonders. But the excruciating pain makes everyone hesitate. I have spent enough on my skin to buy a luxury car, but even I used to tear up during every manual injection session.

The current buzz in Seoul is all about the "No Pain" injection trend. Everyone is talking about i-JECT being the machine that finally makes skin boosters painless. I recently tried the combination of the i-JECT machine with re2O needles to see if the rumors were true. Here is the breakdown.

1. Hand Injection (The OG)

This is the classic method. The doctor injects every spot manually with a syringe. The benefit is that there is almost zero loss of solution, and the doctor can adjust the depth for each specific area. The downside is the hellish pain. The embossing (bumps on the skin) is severe, and bruising is common. If the doctor lacks skill, the depth becomes inconsistent, making the results a gamble.

2. Standard Injector Guns (The Old Trend)

This refers to machines like Derma Shine. The benefit is speed and slightly less pain than manual injections. The fatal flaw is Drug Loss. Solution often leaks when the machine detaches from the skin. That expensive Rejuran flows into the air instead of your face. Also, the noise and vibration of the machine during needle entry induce fear.

3. i-JECT + re2O Needle (The Specialized)

This is what I have settled on. i-JECT is the device, and re2O is the specific needle attached to it. The core difference lies in the technology of the re2O needle. It is a 34G needle, which is much thinner than standard needles, and the cutting edge is extremely sharp, meaning there is almost zero resistance when penetrating the skin.

Here is an industry secret. Pain from machine injections usually comes from the skin being pushed or dragged during needle entry. However, i-JECT penetrates vertically, and the thin re2O needle drastically reduces nerve stimulation. This is exactly why it is gaining the "No Pain" reputation here.

The Real Catch (Why it is hard to find)

You might struggle to find a clinic that actually has this machine. Here is the uncomfortable truth: It takes too long. Compared to standard injector guns that stamp your face rapidly, the i-JECT process is slower and more precise. For "factory-style" clinics that care about high turnover, this machine is a nightmare because it eats up chair time.

Personal Verdict

I was honestly too curious about the hype, so I went and got the procedure myself to verify it. It is definitely much less painful than standard needles. If you are someone who really wants the effects of skin boosters but has been avoiding them because the pain of needles or cannulas is just too unbearable, I strongly recommend trying it with i-JECT.

If you stumble upon a clinic that offers this, stop thinking and pay immediately. It means they prioritize your comfort over their turnover speed.

Insider Tip: When consulting, verify two things with the clinic. First, check if the injector model is i-JECT. Second, confirm they use genuine re2O needles. Some places use a high end machine but cheap out on the needles, which fails to reduce the pain.
