Are the effects and pain mentioned in reviews really true?

“I want to get Rejuran,

but I heard some people actually became drier afterward.”

“I heard the pain from Rejuran is really severe... is that true?”

For many people, clear and healthy-looking skin is always something to aspire to.

People want skin that is firm, with elasticity, without visibly enlarged pores, but it is often hard to notice a big change with home care alone, such as masks or creams.

These forms of home care have difficulty reaching deep into the skin and only temporarily make the surface feel moisturized.

As time passes, you may again experience dryness or a stinging sensation.

At times like this, one option to consider is the skin booster Rejuran.

It continues to draw attention because you can easily find a wide range of reviews just by searching online,

but there are also quite a few people who wonder, “Can I really trust online reviews as they are?”

So today, to help answer these questions, I’ll explain Rejuran in detail.

  • Rejuran that helps with skin regeneration
  • Can one session be enough?
  • If you’re worried about pain

신촌리쥬란 Rejuran that helps with skin regeneration

The key ingredient in Rejuran is polynucleotide (PN), a biocompatible substance extracted from salmon DNA.

This ingredient helps activate the skin’s natural regenerative ability.

Rather than simply injecting a specific ingredient, it plays the role of sending a “regeneration signal” so the skin can recover on its own.

In this process, the oil-and-moisture balance of damaged skin is gradually adjusted, and the production of collagen, elastin, and hyaluronic acid is promoted.

As a result, you can expect fine wrinkles to soften, skin elasticity to improve, and overall skin texture to become smoother.

신촌리쥬란 Can one session be enough?

When looking through reviews, it is common to come across comments saying the skin looked noticeably better right after the procedure.

So some people expect that it will improve right away even with just one treatment.

However, Rejuran is not a treatment that shows immediate changes right after the procedure.

As explained earlier, the PN ingredient acts as a “regeneration signal” that stimulates fibroblasts in the dermis and induces new collagen production.

Therefore, it takes a certain amount of time for collagen to be produced and for the tissue to recover, and skin changes are usually felt after about one month.

Also, it is difficult to expect a dramatic change from just one session.

This is because when considering a skin booster treatment, the skin damage has often already accumulated over a long period of time.

In such cases, there are limits to how much regeneration can be achieved with just one treatment.

Since Rejuran is a treatment that gradually builds collagen production and skin regeneration, repeated sessions of about 3 to 4 times are more effective.

If you continue the treatment consistently like this, the maintenance period also becomes longer, and you can expect more noticeable changes.

신촌리쥬란 If you’re worried about pain

One aspect that is always mentioned in relation to Rejuran is pain.

Because it is injected into the skin one needle prick at a time, there are many reviews saying that pain was felt during the procedure.

In fact, compared with other skin boosters, Rejuran has relatively larger particles, so pressure-related pain can occur during injection.

If you are concerned about pain, considering Rejuran HB+ is one option.

Rejuran HB+ also uses PN as its main ingredient, but it additionally contains lidocaine, a local anesthetic, and hyaluronic acid.

Because of this, pain during injection is relatively reduced, and hyaluronic acid helps PN absorb, making the effects appear more quickly and more clearly.

If pain is a burden for you, it is a good idea to compare this option as well.

Sinchon Rejuran is a skin booster treatment that delivers regeneration signals to the skin based on PN.

After it is injected into the dermis, you can gradually feel the skin becoming firmer over time.

However, it may be difficult to see enough effect from just one session, so it is important to expect gradual improvement through repeated treatments.
