How Long Does Rejuran Last? What Decides It for Your Skin

Hi, this is Time Return.

You are about to invest in your skin, and of course you want to know how long it will be worth it.

"How long does Rejuran last, really?"

"Will I need to come back again and again?"

"If I fly to Seoul once, is that enough?"

Today we answer how long does Rejuran last the honest way, including the part where we do not hand you a number.

The short answer

We cannot give you one fixed length of time, and we would be wary of any clinic that does.

Rejuran is a skin booster. It supports the skin so it can look and feel healthier over time. How long you enjoy that depends on your skin and on how the plan is set. Results vary by individual.

Why is there no single number?

Because skin is not the same from one face to the next.

Rejuran contains polynucleotide (PN) from salmon DNA and is made by PharmaResearch. It goes into the dermis, a layer only about 0.5-2 mm thick. Thin or thick, dry or sensitive, each skin type responds in its own way.

So when someone asks how long Rejuran lasts, the true answer begins with another question: whose skin?

What shapes how long Rejuran lasts?

Three things matter most in our consultation room:

• Your skin itself. The doctor checks thickness, texture and sensitivity first.
• The plan. Injection depth and amount are set to you, not copied from a menu.
• How you look after it. Aftercare guidance follows the session, and following it matters.

We do not invent figures for any of these. If a page promises a number of months or sessions for everyone, ask where it comes from.

How long does Rejuran take to work?

Many people ask this right next to the first question. It is a gradual process, because the aim is better skin quality, not an instant change.

You may see small bumps or mild redness first. These are short-lived reactions that usually settle in about 1-3 days. For the full picture, read our guide to Rejuran downtime.

How often to do Rejuran?

We understand why you want a schedule. But a schedule copied from someone else can be wrong for you.

The doctor looks at your skin and talks with you face to face. Then the plan is set, including how often to come back. If you are travelling, we plan around your dates too.

What helps, and what to skip

Good aftercare supports whatever the treatment is doing for your skin.

NO

• Saunas, steam rooms and hard exercise for the first 1-3 days
• Harsh exfoliating or brand-new skincare right away
• Judging the result from a single photo online

OK

• Moisturizer and sunscreen every day
• Light makeup from 24 hours after
• Gentle washing with lukewarm water

Photos help you understand the process, but they show someone else's skin. If you want to know why the same product looks different across clinics, read why Rejuran results differ by doctor. Our before and after page shows cases from the clinic.

How do we plan it at Time Return?

The doctor consults face to face and injects by hand with Rejuran Healer. That lets the doctor adjust depth, pressure and angle point by point.

Dr. Kim Yoo-ju is a certified Rejuran Healer Expert and Rejuran clinical advisor, with over 10,000 cases in wrinkle, elasticity and skin booster care. You can meet the team on our doctors page. We use genuine product at the exact dose every time, and our signature plasma 5-step anesthesia (5A+) for comfort.
