Rejuran Under Eye: What Can It Do for Tired, Thin Skin?

Hi, this is Time Return.

The skin under your eyes is the first place many people notice they look tired. And it is also the place people feel most nervous about.

"Is it safe to inject there?"

"Will it fix my dark circles?"

"Will it look puffy or strange afterward?"

Today we answer these three questions about Rejuran under eye, the way the doctor explains them in the consultation room.

The short answer

Rejuran under eye is about skin quality. It is a skin booster that supports thin, tired-looking skin, so the skin can look and feel healthier over time.

It is not a quick fix for every under-eye concern. Some concerns come from skin, and some come from structure. The doctor needs to see which one is yours.

What is Rejuran, in one minute?

Rejuran contains polynucleotide (PN) from salmon DNA and is made by PharmaResearch. It is placed into the dermis, the layer under the surface of the skin. That layer is only about 0.5-2 mm thick.

So the question is never "inject or not." The question is how deep and how much, for your skin.

Who does it suit?

You may be a good fit if your main worry is the skin itself:

• Skin that looks thin or crinkled when you smile
• Dull, tired texture under the eyes
• A wish to improve skin quality rather than add volume

It may not be the first answer if your worry is puffiness, deep hollows or dark color. Those can have other causes, and a different approach may suit you better. We will say so directly.

What should you avoid?

The eye area is delicate, so a few ground rules help.

NO

• Pressing or rubbing the area after treatment
• Saunas, steam rooms and hard workouts for the first 1-3 days
• Trying new or harsh skincare right away

OK

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

Small bumps and mild redness are common and usually short-lived. You can read the full timeline in our guide to Rejuran downtime.

What about pain?

Many people ask this first, and it is a fair worry. The skin around the eyes can feel more tender than other areas.

Our answer is preparation. We use plasma 5-step anesthesia (5A+), our signature numbing system for Rejuran. You can see how it works in our pain guide.

Can you see Rejuran eye before and after photos?

Yes, and they are useful. Our before and after page shows real cases from the clinic.

Just remember that photos teach you the process, not your own outcome. Lighting, angle and skin type change how a photo looks. Results vary by individual.

How do we approach the eye area?

The doctor consults with you face to face first. We check skin thickness, texture and sensitivity, then set the depth and amount for you.

We inject by hand with Rejuran Healer, which lets the doctor adjust pressure and angle at each point. Dr. Kim Yoo-ju is a certified Rejuran Healer Expert, and you can meet the team on our doctors page.

If your under-eye skin has been bothering you, start with one message. Tell us your concern and, if you are visiting Seoul, your travel dates, and the doctor will reply with an honest plan. You can also check where we are in Yeouido or read the FAQ first.

Redness, small bumps and mild swelling can appear after injections. Bleeding, infection and inflammation are possible complications. The doctor explains aftercare before you leave.
