Rejuran I (Eye) in San Diego, CA
Rejuran i (Eye) is a specialized Korean skin treatment at Seoule K-Beauty Skin Lab in San Diego that uses polynucleotides (PN) from purified salmon DNA to repair, rejuvenate and brighten the delicate under-eye area. Applied topically after Sylfirm X or microneedling, it strengthens thin under-eye skin and softens fine lines, dark circles and crepiness for a brighter, more rested look.
What is Rejuran Eye?
Rejuran i (Eye) is a formulation developed specifically for the thin, fragile skin around the eyes, where standard treatments can be too aggressive. Its polynucleotides stimulate cell regeneration, improve elasticity and enhance hydration, gently thickening and reinforcing the skin so it looks smoother, firmer and more awake. It is a favorite for people who want natural improvement without the risks associated with heavier treatments in this sensitive zone.
How does it work?
Delivered through micro-channeling or applied after a microneedling pass, the PN molecules absorb into the under-eye skin and trigger repair at the cellular level. Over a short course of treatments they help rebuild collagen, improve texture and reduce the shadowing that makes tired eyes look darker, restoring a fresher, more youthful appearance around the eyes.
What does it treat?
Under-eye fine lines and crepey texture.
Thin, fragile eyelid and under-eye skin.
Loss of firmness around the eyes.
Dark circles caused by thin skin and poor texture.

Who is a good candidate?
Rejuran Eye is ideal if your under-eye concerns come from thin skin, crepiness or texture rather than volume loss or deep hollows, and it is often chosen as a gentle, natural alternative or complement to under-eye filler. During your consultation we assess the cause of your dark circles and recommend the most effective option, since some clients benefit from combining Rejuran Eye with other treatments.
What to expect during your visit
We cleanse and numb the delicate eye area first, then perform the treatment with extra care and precision. The appointment is quick and comfortable, and our specialists take their time so even clients who dislike needles feel at ease. There is little disruption to your day, and results build gradually and look natural.
How many sessions and how long do results last?
A short course spaced a few weeks apart delivers the best results, which continue to improve as the skin repairs and rebuilds collagen. Periodic maintenance keeps the under-eye area looking bright and refreshed over time.
What is the aftercare?
Mild swelling or small bumps may appear for 1-2 days. Avoid rubbing the area, strenuous activity and direct sun exposure, keep the skin moisturized and use sunscreen daily to protect your results.
The under-eye area demands a careful, experienced hand. At Seoule, Rejuran Eye is performed under Medical Director Dr. Lydia Park, MD, using authentic Korean products, and it pairs naturally with Rejuran and Sylfirm X for a full-face glass-skin plan at our San Diego clinic.
Why choose Seoule for Rejuran Eye?
How to prepare for your treatment
Come to your appointment with clean skin and no eye makeup, and avoid retinoids or strong actives around the eyes for several days beforehand. Skipping alcohol for 24 hours helps limit bruising in this delicate area. If you have a history of cold sores or any eye conditions, let us know so we can plan your treatment safely.
Combining treatments for the best results
Rejuran Eye is a natural companion to a full-face plan. It pairs with Rejuran for the rest of the face, with Sylfirm X for overall tightening, and with dermal fillers when hollows also need volume. Many clients treat the under-eye area alongside a K-Beauty Facial so the whole complexion looks brighter and more rested at once.
Results you can expect
Over a short series, clients typically see brighter, firmer under-eye skin, softer fine lines and less crepiness, with dark circles that look lighter because the skin itself is healthier and thicker. Results look natural and build gradually, so no one can tell you have had work done, only that you look more rested. Many people find the eye area is where they notice compliments first.
Why San Diego clients choose Seoule
The under-eye area is one of the most delicate zones to treat, and it rewards a careful, experienced hand. At Seoule, Rejuran Eye is performed under Medical Director Dr. Lydia Park, MD, using authentic Korean products and gentle technique, and we take the time to make even needle-shy clients comfortable. As a dedicated Korean skin care clinic in San Diego, we treat the eyes as part of a whole-face glow plan, not an afterthought.
Not all dark circles are the same, and the right treatment depends on the cause. Some are pigment-related, some come from shadows cast by hollows or volume loss, and many are caused by skin that has simply become too thin and crepey to hide the vessels beneath it. Rejuran Eye is most effective for that last group, because its polynucleotides physically strengthen and thicken the skin, improving texture and resilience rather than just camouflaging the shadow. During your consultation, we look closely at your under-eye area to identify which factors are at play. If thin skin and texture are the main issue, Rejuran Eye is often the ideal choice, and if volume loss is also involved, we may suggest combining it with a small amount of filler or another treatment. This honest, tailored assessment is how we make sure you invest in the treatment that will actually move the needle for your eyes, rather than a generic package. It is also why our clients tend to see natural, lasting improvement instead of a quick fix that fades.
