Skin boosters differ in ingredients, intended uses and treatment routes. Compare the exact product and procedure rather than treating every option as the same injection.
Korean clinics offer different skin-quality treatments, including Rejuran, exosome-based products, RE2O and Laetigen. Their compositions and intended uses differ; suitability depends on the product and your skin assessment.
This comprehensive guide breaks down Korea’s most popular skin boosters to help you find the perfect treatment for your skin.
1. Rejuran Formulations
Rejuran is a polynucleotide (PN) product. PN and PDRN should not be treated as interchangeable product names. PN treatment is not a repair of a patient’s DNA; discuss the intended use and realistic skin-quality goals of the exact formulation.
Rejuran Healer — Classic Repair
Rejuran Healer is a PN formulation. Discuss the intended skin-quality goal, dose, injection plan and follow-up before booking. It is not automatically suitable for every skin type; active inflammation, allergy history and other treatment plans need assessment.
Rejuran HB plus — Deep Hydration
Rejuran HB plus contains PN, hyaluronic acid and lidocaine. The formulation and pain-control considerations differ from Rejuran Healer; lidocaine does not guarantee a painless procedure. Confirm the full product name, dose and any relevant allergy history.
Rejuran i — Eye Area Specialist
Rejuran i is discussed for delicate skin such as the eye area. Under-eye concerns have different causes, so ask whether the proposed treatment addresses your concern. Do not assume a product can correct every type of dark circle or is appropriate immediately after eye surgery.
Rejuran S — Scar Repair
Rejuran S may be discussed in a scar-focused plan. Scar type, depth and active acne affect the choice of treatment. Ask why this formulation is being proposed and whether other procedures are needed; do not infer a higher PN concentration from the product name alone.
How to Choose Your Rejuran
- Daily maintenance / First-timer → Rejuran Healer
- Dry skin / Instant glow → Rejuran HB plus
- Eye area concerns → Rejuran i
- Acne scar repair → Rejuran S
- Best combo → A clinician-selected product and treatment area; combinations are not automatically better
2. Exosome-Based Products — Check the Product and Route
Exosome-based products differ by source, processing, formulation and intended route. A product discussed for topical skin care should not be assumed suitable for injection. Product-specific evidence and instructions matter more than a general promise of cellular regeneration.
Before booking: Ask for the complete product name, its intended route and the expected outcome for your concern. ASCE+ is a product line; ExoSCRT is a technology name, not a separate injectable brand. Do not assume all exosome products have the same effects or regulatory status.
3. RE2O (리투오) — Human Dermal ECM Skin Booster
RE2O (리투오) is discussed as a human dermal extracellular-matrix product. It differs from PN and hyaluronic-acid products. Ask the clinician about the product, preparation, intended use and delivery method; it is not a needle-free alternative simply because it is called a skin booster.
Composition: Human dermal extracellular matrix contains structural components such as collagen. Discuss the specific product’s preparation and suitability, including any relevant allergy history and previous procedures.
How the categories differ: PN, dermal ECM and collagen products have different compositions. Ingredients alone do not establish that one gives faster or longer-lasting results. Ask about the evidence, intended use and alternatives for your specific concern.
Treatment planning: Ask what improvement is realistic for your skin, how response will be assessed and when any repeat treatment should be considered. The schedule and recovery should be set for the particular product and procedure rather than copied from another type of skin booster.
4. Laetigen (레티젠) — Collagen-Based Skin Booster
Laetigen (레티젠) is a collagen-based product, a different category from PN. Before choosing it, discuss its formulation, intended use and relevant contraindications. A collagen ingredient does not by itself establish that the treatment is suitable for your skin or free of reactions.
Before treatment: Confirm the exact formulation, total amount and planned treatment area. Tell the clinician about previous injectable treatments and reactions, and ask how adverse effects would be managed.
Expected change: Discuss the skin concern and how improvement will be evaluated. Immediate appearance after treatment may include swelling; do not assume it represents the final result or a fixed duration of benefit.
Laetigen vs RE2O: Collagen-based and dermal ECM products have different compositions. They are not interchangeable, and using both is not automatically appropriate. Ask why a particular product is being proposed and whether a simpler plan would meet the same goal.
5. Other Popular Korean Skin Boosters
Other product names you may encounter: NCTF, Juvelook and Profhilo belong to different formulation categories. Compare the complete product name, intended use, amount and delivery route. Do not compare a price per session until those details, anaesthesia and taxes are clear.
Who Is It For?
- Dry, dull skin lacking radiance — want deep skin quality improvement
- Enlarged pores, rough texture — seeking baby-smooth skin
- Acne scars, pigmentation — need repair and restoration
- Under-eye fine lines, dark circles — prominent eye area concerns
- Adults seeking advice about a specific skin concern — suitability depends on assessment, not age alone
- After a previous procedure — discuss recovery and timing before adding another treatment
- Concerned about needles — discuss the actual delivery method; a product name does not imply needle-free treatment
Popular Skin Booster Combinations
- Full-face planning: Compare the purpose of each product; do not assume adding more products improves the result.
- Eye area: Match treatment to the cause of the concern rather than a preset combination.
- Scar treatment: Coordinate any injectable and laser plan with the clinician, including recovery time.
- Collagen and ECM products: Discuss whether one product is sufficient before considering a combination.
Skin Booster Pricing in Korea: Compare the Same Specification
Ask for a written quote in Korean won. The product, amount, area and treatment route determine whether two offers are comparable; a session without these details is not a standard unit.
| Treatment | Product | Dose / area | Method | Price conditions |
|---|---|---|---|---|
| Rejuran Healer | Exact formulation | Total mL and area | Manual or device injection | Anaesthesia, taxes and follow-up |
| Exosome-based products | Full product name | Quantity and treated area | Product-appropriate route | Procedure and aftercare charges |
| RE2O | Product and preparation | Total amount and area | Clinician’s product-specific plan | Single session or course |
| Laetigen | Product and formulation | Total volume and area | Clinician’s product-specific plan | Anaesthesia and taxes |
| Combination plan | Each product separately | Amount of each product | Route and sequence | Itemised package inclusions |
Confirm whether anaesthesia, consumables, taxes and follow-up are included. Use the actual payment exchange rate when estimating your travel budget.
What to Expect: Step-by-Step Treatment Process
If you’re coming to Korea for skin booster treatments, here’s exactly what the experience looks like from start to finish:
Before Your Visit
Consultation (online or in-person): A dermatologist reviews your skin concerns — photos, skin type, problem areas, and goals. Many Korean clinics offer free pre-visit consultations via messaging apps. BeautsGo can arrange this for you through WeChat, LINE, or our mini-program.
Before treatment: Tell the clinician about medicines, active skin irritation, allergies and recent procedures. Follow product-specific preparation instructions; do not stop prescribed medicines without medical advice.
Day of Treatment
Step 1 — Cleansing & skin analysis: The clinic removes all makeup and may use a skin analyzer (like VISIA or similar devices) to map your skin’s condition — hydration, pore size, pigmentation, and elasticity levels. This data helps the doctor customize the injection plan.
Step 2 — Pain management: The clinic should explain anaesthesia or other pain-control options, allergy considerations and expected discomfort. Numbing does not make every procedure painless.
Step 3 — Product-specific treatment: Manual injections and injection devices deliver products by injection; microneedling or stamp-assisted topical application is a different route. Use only the route appropriate to the specific product. A topical exosome product is not interchangeable with an injectable; the delivery method must match the product.
Step 4 — Aftercare: Ask which aftercare measures are appropriate and included in the quote. Additional light therapy or masks are not automatically necessary or included.
After Treatment: Recovery Timeline
Treatment day: Follow the clinic’s product-specific instructions on cleansing, touching the area and makeup. Redness, swelling or injection bumps may occur.
Early recovery: Swelling, bruising and tenderness vary. Ask when you can resume makeup, exercise and travel for the procedure you received.
Follow-up: Symptoms should be reviewed if they persist or worsen. Increasing pain, spreading redness or other concerning changes need prompt medical advice.
Assessing results: Arrange the review time with the clinician; different products and routes have different response patterns.
Longer-term review: Compare photographs and your original treatment goal after initial recovery. Do not assume every treatment reaches its final result at the same time.
Maintenance: Any repeat procedure should follow reassessment rather than an automatic schedule for all skin boosters.
Side Effects and Safety: What You Need to Know
Product approval, intended use and treatment route must be checked for the exact product. Availability in a clinic does not by itself establish approval for every advertised use. Discuss contraindications, alternatives and the clinician’s experience before treatment.
Possible early effects: Redness, swelling, tenderness, bruising and injection bumps can occur. Duration varies; symptoms that are severe, worsening or unexpected need assessment.
Other possible complications: Allergy, infection, prolonged swelling, nodules or uneven results may occur. Risk depends on the product and technique. Ask which symptoms require prompt medical attention; a reputable clinic does not eliminate the risk of infection.
Who should NOT get skin boosters: Pregnant or breastfeeding women, people with active skin infections or open wounds in the treatment area, patients on blood thinners (consult your doctor first), individuals with known allergies to salmon DNA (for Rejuran specifically).
How to Choose the Right Skin Booster for Your Skin
With so many options available in Korea, choosing can be overwhelming. Here’s a decision framework based on your primary skin concern:
Wrinkles or texture: Discuss the cause and realistic treatment options. A PN product, collagen product or combination should be chosen after assessment rather than as a preset package.
Dryness: Ask whether skin care or treatment of an underlying condition should come first. If an injectable is proposed, confirm the formulation and reason for choosing it.
Acne scars: Scar type and active acne affect treatment choice. Ask whether the proposed product addresses your particular scar pattern and how it fits with other procedures.
Eye-area concerns: Pigmentation, hollowing and skin laxity are different problems. An eye-area product is not automatically the right treatment for all of them.
Several skin concerns: Agree on the main goal first. Each added product or procedure needs a clear purpose, suitable timing and a separate discussion of risk and cost.
First visit: Start with an assessment and discussion of alternatives. You do not need to commit to a multi-product course before understanding the plan.
Frequently Asked Questions
How often should I get skin booster treatments?
Intervals depend on the exact product, dose, treatment route and skin response. Obtain a product-specific plan from the clinician; do not apply one schedule to Rejuran, exosome products, RE2O and Laetigen.
Is the treatment painful? What about downtime?
Pain and downtime depend on the product and delivery method. Numbing may reduce discomfort but does not eliminate it. Redness, swelling, bruising or injection bumps may occur; ask when to resume makeup and usual activities for your procedure.
What is the difference between Rejuran and regular hyaluronic acid skin boosters?
Hyaluronic-acid and PN products have different formulations and intended uses. Rejuran uses PN; some formulations, such as HB plus, also contain hyaluronic acid and lidocaine. Compare the exact product, dose, route and treatment goal rather than assuming one category is always stronger or longer-lasting.
How much do skin boosters cost in Korea compared to other countries?
Compare quotes only when the product, dose, area, route, number of sessions, anaesthesia and taxes match. A country-level price range without these details is not a reliable like-for-like comparison. Ask for an itemised local-currency quote before converting it for your travel budget.
Can I combine different skin boosters in one visit?
Combination treatment is not automatically appropriate or more effective. The clinician should consider the exact products, delivery routes, skin condition and recovery needs, and explain whether procedures should be separated.
How long do skin booster results last?
Duration varies by product, route and individual response. Ask what evidence supports the proposed treatment and how results will be reviewed. A fixed maintenance schedule or a claim of stem-cell regeneration should not be applied to all exosome products.
Is it safe to get skin boosters if I have sensitive or acne-prone skin?
Sensitive or acne-prone skin needs an individual assessment. Active inflammation, infection, medications and previous reactions may affect timing or suitability. Discuss the main skin concern before choosing an injectable product or combining procedures.
What age should I start getting skin boosters?
Age alone is not a reason to start injectable treatments. Discuss the skin concern, expected benefit, alternatives and risks. There is no universal starting age or requirement to begin in your twenties.
I’m visiting Korea for just a few days — can I get skin boosters?
A short visit may limit treatment and follow-up options. Arrange an assessment before choosing a treatment date, allow time for possible swelling or bruising, and obtain clear aftercare and contact instructions. Do not assume treatment on arrival leaves the rest of a trip unaffected.
