Rejuran in Gangnam: Complete Guide for Foreigners

Rejuran in Gangnam: Complete Guide for Foreigners

Rejuran is one of Korea’s best-known skin booster treatments and is especially popular in Gangnam among international patients interested in improving skin texture, hydration, elasticity, and fine lines.

Rather than adding facial volume like dermal filler, Rejuran is a polynucleotide-based injectable treatment designed to support overall skin quality and remodeling. Research on polynucleotide injections suggests potential benefits for fine lines, texture, hydration, and elasticity, although the evidence base is still developing.

This guide explains what foreigners should know before getting Rejuran in Gangnam.

What Is Rejuran?

Rejuran is a Korean injectable treatment containing polynucleotides, commonly abbreviated as PN.

PN consists of DNA-derived chains that are used in aesthetic dermatology as a skin-rejuvenation treatment.

Rather than immediately changing facial shape, Rejuran is generally used to improve:

• Fine lines
• Skin texture
• Hydration
• Elasticity
• Overall skin quality
• Tired or dull-looking skin

Recent reviews describe PN treatments as promising for skin rejuvenation, although more high-quality research is still needed to establish standardized protocols and long-term effectiveness.

Why Is Rejuran Popular in Korea?

Korean aesthetic medicine places strong emphasis on improving skin quality rather than only changing facial contours.

Rejuran fits this approach because it focuses on gradual skin improvement.

International patients often choose it because:

• It does not dramatically change facial shape
• Results are intended to look subtle
• It can address several skin-quality concerns
• It can be combined with other treatments
• It is widely available in Gangnam
• Many international-friendly clinics offer it

It is particularly popular among patients looking for a more natural-looking rejuvenation treatment.

What Can Rejuran Improve?

Rejuran is commonly used for concerns such as:

• Fine facial lines
• Dry or dehydrated-looking skin
• Uneven skin texture
• Reduced elasticity
• Fine lines around the eyes
• Early signs of aging

A survey of Korean board-certified dermatologists found that common uses of PN injections included cheek fine lines, under-eye and eye-area fine lines, uneven texture, dry skin, and forehead lines.

Results vary between patients, so it should not be considered a guaranteed solution for every skin concern.

Rejuran for the Under-Eye Area

The under-eye area is one of the most popular treatment areas.

Rejuran may be considered for patients concerned about:

• Fine lines
• Crepey-looking skin
• Reduced elasticity
• Thin-looking under-eye skin

However, it does not work like under-eye filler.

Filler primarily adds volume, while Rejuran focuses more on skin quality.

If your main concern is a deep tear trough, eye bags, or significant volume loss, another treatment may be more appropriate.

Rejuran vs Dermal Filler

Rejuran and fillers are very different treatments.

Rejuran:

• Focuses on skin quality
• Does not primarily create volume
• Results develop gradually
• Often used for texture, elasticity, and fine lines

Dermal filler:

• Adds or restores volume
• Can change facial contours
• Produces more immediate structural results
• Commonly used for lips, chin, cheeks, and other volume-related concerns

Patients should choose based on what they actually want to improve.

Rejuran vs Skin Boosters

Rejuran is often grouped together with other Korean skin boosters, but products can work differently.

Some skin boosters primarily focus on hydration, while PN-based treatments are commonly used with broader goals involving skin texture, elasticity, and rejuvenation.

There is no single skin booster that is best for everyone.

Your clinic should consider:

• Skin condition
• Age
• Dryness
• Fine lines
• Sensitivity
• Previous treatments
• Desired result

How Many Rejuran Sessions Are Needed?

Rejuran is commonly performed as a series rather than a one-time treatment.

A survey of Korean dermatologists found that three PN injection sessions spaced approximately four weeks apart were the most commonly recommended treatment pattern.

However, the ideal schedule can vary depending on:

• Skin condition
• Treatment area
• Product used
• Age
• Treatment goals
• Response to previous sessions

Foreign visitors staying in Korea for a short period should ask whether a single session is worthwhile or whether follow-up treatment at home will be needed.

When Will You See Results?

Rejuran is not designed to create dramatic immediate changes.

Some improvement in hydration or skin appearance may be noticed relatively early, while texture and elasticity changes generally develop more gradually.

Research on PN treatments has reported improvements in areas such as wrinkles, texture, and elasticity, but treatment protocols and response vary considerably between studies.

Patients should therefore expect subtle and progressive improvement rather than an instant transformation.

Does Rejuran Hurt?

Rejuran involves multiple small injections into the skin, so discomfort can be more noticeable than with some non-invasive treatments.

Patients may feel:

• Small needle pricks
• Stinging
• Burning sensations
• Pressure
• Temporary tenderness

Gangnam clinics commonly use topical numbing cream before treatment.

Pain tolerance varies, so ask about pain-management options if you are sensitive to injections.

What Does Your Skin Look Like Right After Rejuran?

Small raised bumps are common immediately after treatment because the product is injected at multiple points in the skin.

You may temporarily notice:

• Small injection bumps
• Redness
• Swelling
• Mild bruising
• Tenderness

The appearance usually improves as the injected material disperses and swelling settles.

Because these bumps can be visible, international patients should avoid scheduling Rejuran immediately before important photographs or events.

How Much Downtime Should You Expect?

Rejuran generally does not require long recovery, but it can have more visible short-term effects than Botox.

Temporary reactions may include:

• Injection marks
• Small bumps
• Redness
• Swelling
• Bruising

Systematic reviews of PN treatments generally report mild and temporary side effects, while also noting that larger and higher-quality studies are still needed.

Allowing a few days before an important event can make the experience more comfortable.

Can Rejuran Be Combined With Other Treatments?

Yes. Combination treatment is common in Korean dermatology.

Rejuran may be combined with:

• Laser treatments
• Radiofrequency
• Ultherapy
• Skin tightening treatments
• Botox
• Other skin boosters

A Korean dermatologist survey found that PN injections were frequently combined with lasers and energy-based treatments, including radiofrequency and HIFU.

However, combination treatment is not automatically necessary.

Ask why each additional procedure is being recommended.

Who May Be a Good Candidate?

Rejuran may appeal to patients who want:

• Gradual skin rejuvenation
• Better skin texture
• Improved hydration
• Fine-line improvement
• Better elasticity
• Natural-looking results

It may be less suitable if your main goal is significant facial lifting, major volume restoration, or dramatic contour changes.

In those situations, treatments such as Ultherapy, Thermage, Botox, or fillers may better match the concern.

What Should Foreigners Ask Before Treatment?

Before booking Rejuran in Gangnam, ask:

• Is this genuine Rejuran?
• Which Rejuran product are you using?
• How much product will be injected?
• Which areas will be treated?
• How many sessions do you recommend?
• What results are realistic?
• How much downtime should I expect?
• Who performs the injections?
• What is the total price?
• Is English aftercare available?

Clear answers make it easier to compare Gangnam clinics.

Do Not Choose Based Only on the Lowest Price

Rejuran promotions are common in Seoul.

However, treatment should not be selected only by price.

Consider:

• Genuine product
• Amount used
• Medical provider experience
• Injection technique
• Treatment area
• Consultation quality
• English communication
• Aftercare support

A cheaper treatment may not represent the same product amount or treatment plan.

Plan Rejuran Around Your Seoul Trip

Foreign patients should consider visible injection marks when planning treatment.

If possible, schedule Rejuran before several quieter days rather than immediately before:

• A wedding
• Professional photos
• Important meetings
• Long travel days

Also tell the clinic when you are leaving Korea so that appropriate aftercare and follow-up can be arranged.



Final Thoughts

Rejuran in Gangnam is a popular option for international patients interested in improving skin texture, hydration, elasticity, and fine lines without significantly changing facial shape.

Unlike Botox or fillers, Rejuran is primarily focused on gradual improvement in skin quality.

Current research on polynucleotide treatments is promising, particularly for fine lines, texture, and elasticity, but evidence is still evolving and treatment outcomes vary.

For foreigners visiting Seoul, look for genuine products, experienced medical providers, clear English communication, realistic expectations, and reliable aftercare.

With appropriate treatment planning, Rejuran can be a natural-looking skin rejuvenation option during a visit to Gangnam.
