What is Rejuran i?
Rejuran i is a skin booster made by PharmaResearch, the Korean company behind Rejuran Healer. Like Rejuran Healer, its main ingredient is polynucleotide (PN), purified DNA fragments from salmon that support the skin's natural repair. Rejuran i is formulated for the thin skin around the eyes, where the skin is more fragile and more likely to show lines and dark tones. It is approved by Korea's Ministry of Food and Drug Safety.
What can Rejuran i help with?
Rejuran i is mainly used for fine lines and crepey texture under the eyes, thin skin that lets darker tones show through, and a tired look around the eyes. It improves skin quality rather than adding volume. If you have deep tear troughs or puffy eye bags, your doctor may suggest filler, other treatments or a surgical opinion instead, sometimes alongside Rejuran i.
Why does Rejuran i cost vary?
Visitors often see different quotes for under-eye treatment in Seoul. This is because each clinic plans differently. Some include numbing cream, a doctor consultation and aftercare in the quote, while others list only the product. Some treat only the under-eyes, while others include the crow's feet area. Understanding these differences helps you compare like for like.
What factors affect the cost of Rejuran i?
- Amount of product: the eye area needs a smaller amount than the full face, but this varies with skin condition.
- Number of sessions: a course of about two to three sessions, a few weeks apart, is common.
- Treated area: under-eyes only, or under-eyes plus crow's feet.
- Injection technique: careful manual injection by needle or cannula takes skill and time.
- Who injects: the eye area is delicate, so experience matters.
- Combinations: adding filler, lasers or Botox for crow's feet changes the overall plan.
How many sessions will you need?
Many doctors recommend about two to three sessions spaced two to four weeks apart, followed by maintenance every few months. Because the under-eye skin is thin, results build gradually as the skin becomes stronger and smoother. If you visit Seoul only once, your doctor can plan a single session and advise when to repeat it on your next trip. The number of sessions is a key part of your total cost.
Needle or cannula: does technique matter?
Rejuran i can be placed with a fine needle in small points or with a blunt cannula that spreads product through fewer entry points. A cannula may reduce bruising in some people, while a needle allows very precise placement. Your doctor chooses based on your skin, blood vessels and the result you want. Technique can affect comfort, bruising and cost.
Is Rejuran i different from under-eye filler?
Yes. Under-eye filler, usually hyaluronic acid, adds volume to deep hollows. Rejuran i improves skin quality without adding much volume. Some people need only Rejuran i, some need only filler, and some benefit from both. Because they work differently, combining them changes the total cost but can give a more complete result.
What is the downtime?
You may see small bumps, slight swelling or mild bruising under the eyes for one to a few days. Most visitors can cover the area with concealer the next day. Avoid rubbing your eyes, alcohol and saunas for a short time after treatment. Plan treatment early in your trip if you have photos or events.
How to make sure the product is genuine
Genuine Rejuran i comes in sealed packaging with a label and holographic sticker. A trustworthy clinic opens it in front of you and tells you how much will be used. This matters for both safety and results, especially in such a delicate area.
