'Rejuran effect — how is it?

I’m worried because I heard it hurts a lot,

but if it suits me well, I’m thinking of trying it...'

Choosing a product that matches your individual skin condition and purpose is most important, and if you are concerned about pain, we recommend considering Rejuran HB PLUS. Interest in Rejuran and consultation requests have increased a lot, since it is said that many celebrities known for looking young receive it.

In particular, many people in their 30s and 40s who are highly interested in skincare and are beginning to notice signs of aging inquire with concerns.

Even if they have heard a lot about the Rejuran procedure, many still say they are not sure what the effects are, how painful it is, or whether they are the right candidate for it.

So today, let’s take a detailed look at the principle behind the Rejuran procedure, its effects, how much it hurts, and who it may be suitable for.

Is Rejuran made from salmon?

Rejuran is made with a component called PN (Polynucleotide), a DNA substance extracted from salmon testes.

Why salmon, among so many types of fish? Because it has excellent compatibility with the human body.

Salmon DNA has a structure very similar to human DNA, so it acts stably even when introduced into our body.

An interesting point is that salmon’s reproductive cells are not active in the sea, so the raw material can only be obtained by catching them when they swim upstream during spawning season.

The amount that can be extracted from one salmon is only about 80 to 100 g, making it a surprisingly rare raw material.

Principle and timing of effects

When Rejuran is injected into the skin, it stimulates skin cells in the dermis layer and encourages them to produce ingredients that help skin elasticity, such as collagen.

Unlike topical cosmetics or ampoules, it directly delivers skin-regeneration ingredients through injections, so it has an effect that helps recovery from within the skin.

The timing of when effects appear varies from person to person, but because the skin needs time to regenerate, it is usually felt after about 2 to 4 weeks.

As ingredients such as collagen and elastin, which make up the skin, build up, fine lines and pores improve and skin elasticity is naturally restored.

I heard it hurts quite a bit?

Many people say they are worried because they hear it hurts.

To be honest, if the procedure is done without any measures, Rejuran can be quite painful.

As mentioned earlier, PN, the main ingredient in Rejuran, is a substance with large molecular size, so pain can occur as it is injected into the skin.

However, pain can be minimized by applying enough anesthetic cream and using a very thin needle.

In addition, there is also the option of receiving the procedure with Rejuran HB PLUS, which contains lidocaine, a local anesthetic ingredient.

It is a version with pain reduced by about 53% compared to original Rejuran, so it can be received more comfortably.

Who is it good for?

In general,

  • If the skin is dull or feels very dry from within

  • If fine lines around the eyes or mouth are a concern

  • If skin elasticity has significantly decreased

you can expect benefits.

However, this is only an explanation based on general cases, so we hope you make your decision after checking through a proper skin condition diagnosis and consultation to see whether it is also a good fit for you.
