Skin Boosters in Gangnam: Rejuran, Juvelook, Exosomes and PDRN

Skin booster treatments at Sia Clinic Gangnam Seoul

Skin boosters are one of the most popular treatments among foreigners visiting Korea — and it's easy to see why. They're minimally invasive, require little to no downtime, and deliver results that are immediately visible. But walk into any clinic in Gangnam and you'll quickly find yourself facing a menu of names that mean very little if you're new to this: Rejuran, Juvelook, Exosome, PDRN, Hydro Injection, Belotero Reviveandetc.

They're not the same thing. Each works differently, targets different skin concerns, and suits different skin types and ages.

This guide breaks down every major skin booster available in Korea so you can walk into your consultation knowing exactly what to ask for.

What Is a Skin Booster?

A skin booster is an injectable treatment that delivers active ingredients directly into the dermis — the deeper layer of your skin — where topical skincare simply can't reach. Unlike fillers, which add volume to specific areas, skin boosters work across the entire face (or neck, hands, and body) to improve overall skin quality: hydration, elasticity, texture, and radiance.

Results typically build over several weeks and can last anywhere from a few months to over a year, depending on the treatment and your skin condition.

Rejuran

Best for: Damaged skin, fine lines, enlarged pores, acne scarring, overall skin quality

Rejuran is arguably the most well-known skin booster in Korea, and for good reason. Its active ingredient is polynucleotide (PN), a DNA-derived compound extracted from salmon that stimulates the skin's natural repair process. Rather than simply adding moisture, Rejuran encourages your skin cells to regenerate and heal from within.

The result over time is noticeably smoother texture, tighter pores, reduced fine lines, and a more even, resilient complexion. It's particularly effective for people whose skin has been damaged by sun exposure, acne, or aging.

Rejuran HB is a variation that combines the same PN technology with hyaluronic acid, adding deep hydration on top of the repair benefits. It's a good option if your skin is both damaged and dehydrated — which is common in colder months or for people who travel frequently.

PDRN

Best for: Skin regeneration, sensitive or inflamed skin, post-treatment recovery

PDRN (Polydeoxyribonucleotide) is closely related to Rejuran's PN technology — both are DNA-derived and work by activating the skin's repair mechanisms. The key difference is that PDRN has a smaller molecular weight, which means it absorbs more easily, but it is less concentrated than Rejuran.

If you're planning multiple treatments during your trip, PDRN is worth discussing with your consultant as a complementary add-on.

Juvelook Skin

Best for: Dull skin, early signs of aging, skin that needs a collagen boost

Juvelook is a newer generation skin booster that combines hyaluronic acid with PDLLA microspheres — tiny biodegradable particles that dissolve slowly in the skin over time, continuously stimulating collagen production for months after your treatment.

Where Rejuran focuses on repair, Juvelook focuses on renewal and brightness. It's particularly popular among patients in their late 20s and 30s who want to address early signs of aging and dullness before they become more pronounced.

The collagen-stimulating effect also means results improve progressively over 4–8 weeks and last longer than many other skin boosters — often up to a year or more.

Exosome

Best for: Skin regeneration, anti-aging, sensitive skin, inflamed skin, acne-prone skin, post-laser recovery

Exosomeis one of the most talked-about developments in Korean aesthetic medicine right now. Exosomes are microscopic particles naturally produced by stem cells that carry growth factors and signaling proteins — essentially instructions that tell your skin cells to repair and regenerate.

As an injectable treatment, exosomes deliver an intensive regenerative signal directly into the skin, stimulating collagen, improving elasticity, and accelerating healing. The results are particularly impressive for patients with more mature skin, or those recovering from intensive laser or aesthetic procedures.

Exosomes also have notable anti-inflammatory properties, making them an excellent option for people with inflamed skin or acne-prone skin. By calming inflammation at a cellular level, exosomes help reduce redness and irritation while simultaneously supporting the skin's repair process — a combination that most other boosters can't offer.

Because exosomes work with the skin's own biology rather than introducing a foreign substance, they're also very well tolerated by sensitive skin types.

Hydro Injection

Best for: Immediate hydration and radiance, pre-event glow

The Hydro Injection (sometimes called a water glow shot) is the most accessible entry point into skin boosters. It delivers hyaluronic acid into the skin through multiple micro-injections, resulting in an immediate plumping and glowing effect.

Unlike the regenerative boosters above, the Hydro Injection isn't primarily about long-term skin repair — it's about instant skin quality. Think of it as a deep hydration reset that makes your skin look noticeably more dewy, even, and alive within 24 hours.

It's a great option if you're new to injectables, want to see results quickly during your trip, or want something with virtually less downtime before sightseeing or events.

Belotero Revive

Best for: Dehydrated skin, fine surface lines, mature skin needing both hydration and firmness

Belotero Revive is a skin booster from the well-established Belotero filler family, formulated specifically for overall skin quality rather than volumizing. It uses a unique hyaluronic acid and glycerol complex — the glycerol works alongside HA to attract and lock in moisture at a deeper level, providing longer-lasting hydration than HA alone.

It's particularly effective for patients with noticeably dehydrated skin, fine surface lines, or mature skin that needs a quality boost rather than obvious filling. The results are natural-looking and build progressively over several weeks.

How to Choose the Right Skin Booster

With so many options, the honest answer is: the right skin booster depends on your skin, not what's trending. Here's a full comparison of every booster at Sia Clinic to help you narrow it down:

Treatment	Key Ingredients	Main Concerns	Best Suited For	How Long Results Last
Rejuran	Polynucleotide (PN)	Damaged skin, enlarged pores, fine lines, acne scarring	All ages; especially those with skin damage or aging concerns	3-4 months
Rejuran HB	PN + Hyaluronic Acid + Lidocaine	Damaged + dehydrated skin, fine lines, dullness	Dry or damaged skin; great in colder months or for frequent travellers	3-4 months
PDRN	Polydeoxyribonucleotide	Skin regeneration, redness, post-treatment recovery	Sensitive skin; anyone combining with laser or other treatments	2-3 months
Juvelook Skin	HA + PDLLA microspheres	Dullness, early aging, loss of radiance, collagen depletion	Late 20s–40s; prevention and early correction	4-9 months
Exosome	Stem cell-derived growth factors	Skin regeneration, elasticity, deep anti-aging, inflammation, acne-prone skin, post-laser recovery	Mature skin; sensitive skin; inflamed or acne-prone skin; post-procedure recovery	4-6 months
Hydro Injection	Hyaluronic acid comple	Dehydration, lack of glow	dry skin; first-timers; pre-event glow; anyone with less downtime	1-2 months
Belotero Revive	Hyaluronic acid complex + Glycerol	Dehydration, fine surface lines, loss of firmness, redness	Mature or very dry skin needing both hydration and structure	6–9 months

Note: Duration varies by individual skin condition, lifestyle, and number of sessions. Your consultant will advise based on your skin analysis.

That said, a proper skin analysis before any recommendation is essential. What works for one person's skin type may not be the right choice for another, even if the concerns look similar on the surface.

Can You Combine Skin Boosters With Other Treatments?

Yes — and in Korea, combination treatments are very common. Skin boosters are frequently paired with:

Laser toning (e.g. Pico laser) for pigmentation and texture

HIFU or RF lifting for patients who want both hydration and firmness

Aqua Peel as a prep treatment before boosters for better absorption

If you're visiting Seoul for a short trip and want to maximize results, it's worth discussing a combination plan with your consultant during your initial skin analysis.

Why Get Skin Boosters in Korea?

A few reasons Korean clinics stand out for these treatments:

Access to the latest formulations — treatments like Juvelook and Exosome are available in Korea well before they reach most other markets

Competitive pricing — skin boosters in Korea are significantly more affordable than in Western countries or Southeast Asia for equivalent quality

Experienced practitioners — skin booster injections require technique and precision; Korean clinics perform these treatments at extremely high volume, meaning the skill level is consistently high

Frequently Asked Questions

Q: How many sessions of skin booster do I need?

A: Most skin boosters show noticeable results after just one session, which is why they're popular among tourists visiting Korea for a short trip. However, for optimal and longer-lasting results, a course of 2–3 sessions spaced 2–4 weeks apart is typically recommended. Your consultant will advise based on your skin condition and how long you're staying in Seoul.

Q: Is it safe to get a skin booster in Korea as a foreigner?

A: Yes — skin boosters are minimally invasive, well-established treatments with strong safety records when performed correctly. The key is choosing a clinic where licensed medical staff perform the injections, proper skin assessment is done beforehand, and aftercare instructions are clearly communicated. All of these are standard practice at Sia Clinic.

Q: How long does a skin booster treatment take?

A: Most skin booster sessions take between 30–60 minutes including consultation and numbing time. Numbing cream is applied beforehand to minimize discomfort, so the actual injection portion is usually quite quick. It's an easy treatment to fit into a day of sightseeing.

Q: Does a skin booster hurt?

A: Numbing cream is applied before treatment, so most patients experience only mild pressure or a slight stinging sensation during injection. Discomfort is generally very manageable and short-lived.

Q: Can I wear makeup after a skin booster?

A: It's recommended to avoid makeup for at least 12–24 hours after treatment to reduce the risk of irritation or infection through the micro-injection points. Most patients have minimal visible marks by the next day.

Q: Can I combine a skin booster with other treatments on the same trip?

A: Yes — in fact, combination treatments are very common in Korea. Skin boosters pair well with laser toning, aqua peels, and lifting treatments. The key is sequencing them correctly and allowing enough recovery time between procedures. Discuss your full treatment wishlist during your initial consultation so your plan can be scheduled properly around your trip dates.

Q: What is the difference between a skin booster and a filler?

A: Fillers are designed to add volume to specific areas (such as lips or cheeks), while skin boosters are designed to improve overall skin quality across a broader area. Skin boosters hydrate, repair, and stimulate collagen — they don't change the shape or structure of your face.
