Rejuran I: What It Can Realistically Change Under Your Eyes, and Who Should Skip It

I'm Dr. Hyunji Kim, director of Delphic Clinic in Gangnam, one minute from Sinnonhyeon Station Exit 3. I trained through Korea University Medical Center and I'm a member of the Korean Academy of Aesthetic Surgery & Laser Medicine and the Korean Filler Society. The eye area is where lifting, filler and skin-booster work meet, so I spend a lot of consultation time on it, including on Rejuran I.

Several times a week someone points under their eye and asks, "Will Rejuran I fix this?" Usually it is a person in their thirties or forties whose concealer has started settling into fine lines. Sometimes Rejuran I is the right answer, and sometimes the problem is something it cannot touch. This post is about telling those apart before you book.

Why the eye area gets its own version

The skin beneath the eyes is among the thinnest on the face, it moves every time you blink or smile, and it bruises easily. A product and technique that work well on the cheeks are not automatically right there. Rejuran I was made for that area, using the same polynucleotide (PN) idea as other Rejuran products, derived from salmon DNA, in a form suited to delicate skin.

I will not repeat the general Rejuran background here; you can find it in my Rejuran first-timer's guide. This post stays under the eyes.

Crepey, hollow, dark or puffy? A four-type eye check

Look in a mirror with the light in front of you, then tilt your chin down slightly. Try each test below. Most people have one dominant type, and some have two.

Crepey skin is where Rejuran I fits most naturally. With hollows I may discuss volume options separately, and with pigment or puffiness the conversation usually goes somewhere else entirely. If what you see is a cluster of tiny white bumps rather than lines, that may be milia, which I covered in how to get rid of milia under the eyes safely.

What changes, and what stays the same

When Rejuran I suits the skin, the change patients describe is gradual: the under-eye skin looks less papery, fine lines are a little softer, and makeup settles less into creases. It builds over weeks and usually over a short series, often spaced around two to three weeks apart. It is not a same-week transformation.

What stays the same is the structure. A deep tear trough, fat bags or a genetic darker tone will still be there. I would rather say that now than have you judge the treatment against something it was never designed to do.

Under the eyes, I diagnose the shadow before I treat it. Half the disappointment I see comes from treating the wrong cause.— Dr. Hyunji Kim, Delphic Clinic

When I tell someone not to book Rejuran I

• Puffy bags or fat bulges are the main concern: Rejuran I will not reduce them.
• A deep hollow is the main concern: thin-skin support alone will not fill it.
• Active irritation, infection or a skin condition around the eyes: we wait until it settles.
• An important event within the next few days: bumps and possible bruising need time to fade.
• An expectation that one session will look like a filler result: it works differently and more slowly.

The days after an eye session

1. 1

   Same day

   Small raised bumps along the treated line are normal. A cool compress can help with comfort.

2. 2

   Days one to three

   Bumps usually settle within one to three days. The eye area can bruise more easily, and a bruise may take longer to fade.

3. 3

   Following weeks

   Judge the skin gradually. If we planned a series, the next session is usually two to three weeks later.

If the bumps or any discomfort are what you are nervous about, I wrote about the three complaints I hear most after Rejuran and how to plan your social days around them.
