"They say Rejuran helps with skin regeneration...

Is that really true?"

When looking into Rejuran, you often see the phrase "skin regeneration."

But among those who have actually received it, some say, "I’m not sure my skin has regenerated."

There is a reason why these differences occur.

Today, we’ll go through how Rejuran Healer works to regenerate the skin, and why the same procedure can feel different from person to person.

How does Rejuran regenerate the skin?

The key ingredient in Rejuran Healer is PN (polynucleotide).

It is a DNA-derived ingredient extracted from salmon. When this ingredient enters the skin, it helps send signals that promote cell regeneration.

To explain it more simply, PN gives damaged skin cells the signal to "rebuild," while also promoting the production of collagen and elastin.

That is why Rejuran is a procedure that helps strengthen the skin’s own recovery ability from within.

However, this regenerative process takes time.

The skin does not improve right after the injection; instead, changes appear gradually over 2 to 3 weeks as cells become active and new collagen is formed.

Yeongdeungpo Rejuran Why the effects may feel different

There are three main reasons why the effects of the same Rejuran treatment can feel different.

The first thing to check is the injection depth.

Rejuran’s PN ingredient needs to reach the dermis to work properly. The dermis contains the cells that produce collagen and elastin.

If the injection is too shallow, the regenerative signal is not delivered properly.

On the other hand, if it is too deep, pain may be reduced, but it passes beyond the dermis, which also lowers the effect.

In other words, even if the same amount is injected, the result can be completely different depending on whether it is delivered to the correct layer.

The second is the amount used.

The required dosage of Rejuran varies depending on the area and the purpose.

If you want focused care only around the cheeks, 2 cc may be enough, but if you want to improve overall facial skin texture and elasticity, 4 cc is more suitable.

No matter how accurately it is injected, if the amount is insufficient, the regenerative response may not occur adequately.

The third is the number of sessions and the treatment interval.

It is difficult to judge the effect of Rejuran after just one session. Because the skin regeneration cycle is about 28 days, the treatment needs to be repeated in line with that cycle for the effect to accumulate.

Usually, you need at least 3 sessions at intervals of 3 to 4 weeks to notice visible changes.

It may be a little too soon to say, "It doesn’t work," after just one treatment.

To summarize, it needs to be injected at the correct depth, enough of it needs to be delivered to that depth, and the process needs to be repeated for the effects to appear.

If even one of these three is missing, the effect you feel from the same Rejuran treatment will inevitably differ.

Yeongdeungpo Rejuran Healer What to check to get the proper effect

If you want to see the skin-regenerating effects of Rejuran properly, there are a few things worth checking.

First, see whether your concern is suitable for Rejuran.

Rejuran Healer is effective for fine wrinkles, improving skin texture, and restoring elasticity. It is suitable for people who feel their pores have become enlarged, their skin has become thinner, or their overall complexion has become dull.

On the other hand, if you are concerned about deep wrinkles or loss of volume, Rejuran alone has its limitations. In such cases, it is better to combine it with filler or other procedures.

Next, check whether the plan includes enough sessions and an appropriate dosage.

As mentioned earlier, 3 or more sessions at 3- to 4-week intervals are the standard. The dosage also needs to be set according to the target area for the effect to be expected.

Lastly, you should also pay attention to post-procedure care.

Right after the procedure, small raised bumps from the injections, called embossing, may appear.

In most cases, they subside within a day or two, so there is no need to worry.

However, during this time, you should avoid strong massage or hot saunas, and apply sunscreen carefully to help prevent pigmentation.

Today, we talked about whether you can see skin-regenerating effects with Yeongdeungpo Rejuran Healer.

As mentioned above, if the procedure is done with the correct depth, an appropriate amount, and enough sessions, you will likely see skin regeneration effects.
