What Is Rejuran I (Eye)?
Rejuran I (Eye), also known as Rejuran Eye, is a specialized injectable skin booster designed specifically for the delicate skin around the eyes. Unlike standard Rejuran Healer used on the full face, Rejuran I (Eye) uses a salmon-derived PN (Polynucleotide) formulation with a lower concentration and finer consistency, making it safe and suitable for the thin, sensitive tissue of the under-eye area.
The treatment works by delivering PN directly into the dermis beneath the eyes, where it stimulates the skin's natural repair mechanisms, improves hydration, and gradually rebuilds elasticity. The result is a more rested, smoother, and rejuvenated appearance — without the use of fillers or Botox.
Why the Under-Eye Area Needs Special Care
The skin around the eyes is the thinnest on the entire face — roughly 0.5mm, compared to 2mm elsewhere. This makes it the first area to show visible signs of aging, fatigue, and environmental stress. Common concerns include:
Fine lines and crepey texture under the eyes
Loss of volume and skin laxity
Dark, dull, or dehydrated appearance
Thinning skin that reveals underlying structures more prominently
Standard skincare products and even most clinic treatments are not formulated with this delicate zone in mind. Rejuran I (Eye) was developed specifically to address these concerns with a targeted, biocompatible approach.
Who Is Rejuran I (Eye) For?
Rejuran I (Eye) may be a suitable option for those who:
Notice fine lines or wrinkles forming around the eyes
Experience under-eye volume loss or declining skin firmness
Have dry, thinning skin in the periorbital area
Are looking for natural, gradual eye rejuvenation
Prefer to care for the eye area without relying on Botox or hyaluronic acid fillers
It is particularly popular among international patients seeking a natural-looking result, with no significant downtime.
How Forena Clinic Performs Rejuran I (Eye)
At Forena Clinic in Hongdae, Rejuran I (Eye) is performed exclusively by the clinic's medical doctor using precise manual injection. The doctor injects PN directly into the dermis layer beneath the eyes using a fine needle, with careful attention to placement, depth, and minimizing product loss. This hands-on approach allows for targeted treatment tailored to each patient's specific concerns and under-eye anatomy.

What to Expect: Before, During & After
Before Treatment
A numbing cream is applied to the eye area prior to the procedure, so most patients find the experience manageable. Sensitivity varies by individual.
During Treatment
The procedure typically takes approximately 10 minutes depending on the method used. The doctor will assess and treat both under-eye areas with careful, targeted injections.
Immediately After
Some patients experience mild embossing (small bumps), redness, or minor bruising around the treated area. These effects generally resolve within 2–5 days. Daily activities can typically resume right away, though it is advisable to allow buffer time before any important events.
Results Timeline
Many patients begin to notice improvements in skin texture and hydration within 1–2 weeks of their first session. Results continue to develop over the recommended 3-session course, with effects building cumulatively.
Aftercare Guidelines
To support healing and optimize results after Rejuran I (Eye), Forena Clinic advises:
The embossing effect typically subsides naturally within 2–3 days
Avoid alcohol, smoking, saunas, and intense exercise for 1 week after treatment
Apply sunscreen daily and keep the skin well-moisturized
Bruising or swelling around the treated area may last 1–2 weeks but typically resolves naturally
If the treated area becomes severely red or painful, contact the clinic immediately
Side effects such as bleeding, infection, and inflammation may occur and can vary by individual.
