ABOUT REJURAN I

What is Rejuran i?

Rejuran i is part of the PN (polynucleotide) based Rejuran line, developed for thin, delicate areas such as around the eyes.

With lower viscosity and better spreadability than original Rejuran, it can be applied more delicately to thin areas such as under and around the eyes, and treatment can be planned for eye-area fine lines and loss of elasticity.

TREATMENT POINT

The eye area is the thinnest skin on the face —
it needs a more delicate approach

The eye area has thin skin and moves a lot, so fine lines and loss of elasticity show easily.
Rejuran i is designed to be applied more gently with these characteristics in mind.

POINT 01

Designed for the Eye Area

A line designed with lower viscosity and higher spreadability than original Rejuran for thin, sensitive eye-area skin.

02

PN-Based Skin Care

Based on PN, it targets elasticity and overall condition of thin, weakened eye-area skin.

03

Fine Lines · Elasticity

Addresses crow’s feet that appear when smiling, or under-eye skin that looks thin and less firm.

04

Natural Eye-Area Change

Rather than heavily filling a specific area, we plan natural improvement by looking at the skin’s condition, elasticity and texture.

EYE POINT

Under-eye concerns may look the same,
but their causes can differ

Fine lines, thinning skin, loss of elasticity, hollows or shadows may look alike but have different causes. It is important to check skin thickness, movement, volume and treatment history before deciding the right direction.

  • When under-eye skin feels thinner and weaker than before
  • When crow’s feet stand out when you smile
  • When you want natural eye-area change rather than overfilling
  • When you want a delicate skin booster tailored to your eye area

Q&A

Rejuran i Q&A

Q. How is Rejuran i different from regular Rejuran?

Both contain PN as the main ingredient, but Rejuran i has lower viscosity and higher spreadability, designed for easier application to thin skin such as around the eyes.

Q. Can it be used for dark circles?

Dark circles have many causes, including thin skin, pigmentation, visible vessels, hollows or puffiness. If thin, less firm skin is a factor, a treatment considering eye-area skin condition may be reviewed, but depending on the cause another treatment may be more suitable, so diagnosis comes first.

Q. Is it the same as under-eye filler?

Rejuran i differs in purpose and approach from fillers that directly add volume. The right treatment depends on whether the main issue is under-eye hollowness or thinning skin, fine lines and loss of elasticity.

Q. Can I return to daily life right after treatment?

As an injection, redness, swelling, bruising, tenderness or temporary bumps may occur depending on the person. If you have an important event, plan with plenty of time, and adjust face washing, makeup and exercise according to the medical team’s guidance.

Q&A

What should I know before Rejuran i?

How many Rejuran i sessions are recommended?

It depends on the skin around your eyes, but a course is usually several sessions 2–4 weeks apart, followed by maintenance based on your eye-area condition.

How is the treatment performed?

Numbing cream is applied around the eyes, then the ingredient is injected with fine needles suited to thin skin. Its low viscosity is designed to spread evenly in the delicate eye area.

Isn't the eye area especially painful?

The eye area can be more sensitive, so numbing cream is applied thoroughly. If you are sensitive to pain, you can ask about MATRX conscious sedation.

What is the recovery period?

The eye area swells and bruises easily, so swelling or slight bruising may last a few days. Allow about a week before important events.

What are the aftercare instructions?

Avoid eye makeup and contact lenses on the day, and do not rub your eyes. Avoid saunas and alcohol for a few days and moisturize well.

Who should not have Rejuran i?

If you are pregnant or breastfeeding, have inflammation or wounds in the treatment area, or have had a hypersensitivity reaction to the same ingredient, treatment should be postponed or another option considered. Please tell us about your medication and medical history during consultation. Please also tell us if you recently had surgery or a procedure around the eyes.

When will I see results and how long do they last?

Changes in eye-area texture and fine lines are usually felt gradually over several sessions. Duration varies, so maintenance intervals are set to your eye-area condition.

How long does the treatment take?

Usually about an hour including numbing; the injection itself is quick. It may take longer if combined with other areas.

The number of sessions, duration of results and recovery time vary depending on individual skin condition. Details will be explained after consultation.
