What is Rejuran?
Rejuran is a Skin Booster treatment that restores skin from within. Classified as a Skin Healer, its key active ingredient is Polynucleotide (PN) — derived from salmon DNA. It focuses on repairing weakened skin and strengthening the skin's structure, resulting in smoother texture, refined pores, and improved hydration for a radiant, glass-like complexion.
What Does Rejuran Help With
Rejuran focuses on restoring overall skin quality and is well suited for those looking to improve their skin from the ground up. It helps with the following:
- Restoring weakened and damaged skin
- Strengthens the skin barrier.
- Boosting hydration for plumper, more radiant skin and longer-lasting makeup wear
- Refining the appearance of pores, smoothing skin texture, and mildly improving shallow acne scars
Results vary depending on individual skin condition. Continuous treatment as recommended by a physician is advised for more noticeable outcomes.
Key Ingredients in Rejuran
Rejuran's primary active ingredient is Polynucleotide (PN) at a concentration of 2%, extracted from natural salmon DNA.
What Is Polynucleotide (PN)?
Polynucleotide (PN) is a compound derived from natural salmon DNA that is highly biocompatible with human skin. It undergoes a purification process to produce a clear, colorless gel.
Once injected into the skin, it stimulates cellular repair and regeneration, gradually restoring and strengthening damaged skin. It can be administered at multiple areas including the forehead, cheeks, and chin.
How Does Rejuran Work to Hydrate the Skin?
Rejuran delivers PN directly into the skin to repair damaged cells and stimulate regeneration. As the skin undergoes continuous repair, its structure becomes stronger and its ability to retain moisture improves.
PN also promotes the release of growth factors, reduces inflammation, and stimulates collagen and elastin production — resulting in progressively more hydrated, radiant, elastic, and healthy-looking skin.
Does Rejuran Help with Acne?
Rejuran was not developed as a direct acne treatment, but it helps strengthen the skin and reduce inflammation. A stronger skin barrier lowers the likelihood of irritation and inflammatory responses.
Those with active inflammatory acne or significant comedones are advised to seek targeted acne treatment alongside Rejuran for more effective results.
Rejuran and Acne Scar Management
For shallow to moderate acne scars not caused by foreign substances or acne injections, Rejuran can provide a degree of improvement by stimulating collagen production and repairing deeper skin layers. With continued treatment, the skin becomes firmer and smoother, and shallow acne scars may appear less pronounced over time.
What Skin Concerns Is Rejuran Suitable For?
Rejuran is suited for those looking to restore skin quality from within, addressing a range of concerns — particularly:
- Weak, thin, dull, or frequently laser-treated skin
- Dry, dehydrated, or lacklustre skin with poor makeup wear
- Enlarged pores, fine lines, uneven texture, or acne scarring
- Sun-damaged or pollution-exposed skin prone to sensitivity and irritation
- Those seeking healthier, glowing skin and a Glass Skin appearance
Who Should Avoid Rejuran?
While Rejuran has a strong safety profile, certain groups should avoid it or consult a physician beforehand:
- Those taking blood thinners or medications affecting blood coagulation
- Those with certain autoimmune conditions
- Those who are pregnant or breastfeeding
- Those with skin inflammation, infection, or open wounds in the treatment area
- Those with seafood allergies (if the allergy is to specific seafood but not salmon, a physician consultation is recommended before proceeding)
Rejuran Results – Real Cases at MEGA CLINIC
How Long Do Results Last?
Within 5–7 days after the injection, the skin will begin to feel smoother, more refined in texture, and more hydrated.
For a first session, results typically last around 2 months, depending on individual skin condition. Those with a stronger baseline skin condition may experience longer-lasting results.
How Many Sessions Are Needed for Glass Skin?
For a clearly visible Glass Skin result, a course of 3–4 consecutive monthly sessions is recommended. With full skin restoration, results can be maintained for 6–8 months.
How Often Should Rejuran Be Repeated?
For the first three sessions, injections are recommended every 3–4 weeks. After that, maintenance sessions can be scheduled every 3–4 months, or whenever the skin begins to show signs of concern or a boost is desired.
How Many CC Per Session?
Each box of Rejuran contains 2 syringes of 2.7 CC each. The amount used depends on the treatment area and skin condition, as assessed by the physician:
- Full face – 5.4 CC
- Cheeks only – 2.7 CC
- Forehead and chin – 2.7 CC
Pre-Treatment Preparation
To ensure safety and optimal results, the following is recommended before your Rejuran session:
- Research and select a clinic that meets medical standards, with a qualified and licensed physician.
- Inform the physician of any drug allergies, underlying medical conditions, regular medications, pregnancy, or breastfeeding status.
- Verify the Rejuran product packaging with the clinic before the treatment begins.
- If concerned about bruising, avoid medications or supplements that may increase bruising risk — such as aspirin, vitamin E, vitamin K, fish oil, and evening primrose oil — for 7 days before and after the injection.
What Does the Rejuran Injection Process Involve?
After the physician consultation and skin assessment, the skin is cleansed and numbing cream is applied for approximately 30–45 minutes.
The physician then injects Rejuran across the face using a shallow injection technique in a dot-matrix pattern, administered directly from the original syringe without dilution, to ensure consistent and effective results.
Can Rejuran Be Administered with a Device?
Rejuran can be delivered using the Hycoox device, which causes slightly less discomfort while distributing the solution evenly. The device functions similarly to micro-needling, using a 9-needle head to release the solution simultaneously — enabling precise, uniform delivery with controlled depth, volume, and rhythm. This is particularly suited for areas requiring greater precision or cases where accuracy is a priority. An additional charge of 1,000 THB per session applies.
Can Rejuran Be Injected If I Have Active Acne?
Yes, the physician will avoid areas with active acne during the injection. However, if inflammatory acne is present across multiple areas of the face, treating the acne first is recommended to ensure the skin is fully ready for the treatment.
Post-Treatment Aftercare
Yes, the physician will avoid areas with active acne during the injection. However, if inflammatory acne is present across multiple areas of the face, treating the acne first is recommended to ensure the skin is fully ready for the treatment.
What Side Effects Can Occur After Injection?
- Mild stinging or irritation at the injection sites is normal and will gradually subside.
- Small raised bumps from the product may appear but typically resolve on their own within 2 days. Avoid pressing, massaging, or squeezing the injected areas.
- Needle marks and bruising will fade gradually within 7–14 days. A bruise-reducing cream can be applied and makeup can be used to cover the area.
How to Verify Your Rejuran Product
Before your Rejuran session, the product can be verified as follows:
- A hologram sticker on the box can be scratched to reveal and scan a QR code.
- Scanning the QR code redirects to the SW Healthcare official website.
- The product has a Thai-language label and is certified by the Thai FDA.
- Medical device license number: 65-2-1-2-0011893
- Lot number, manufacturing date, and expiry date are clearly indicated.
- Each box contains 2 syringes in sterile pouches, along with product documentation.
Always verify these details with clinic staff for confidence and safety.

FAQ – Frequently Asked Questions About Rejuran
Q: Does Rejuran help with dark spots and post-acne marks?
Rejuran is not specifically designed to reduce dark spots or post-acne marks. It works by restoring and strengthening the skin from within. For those looking to target dark spots and pigmentation,Aura White injections are recommended — a treatment specifically formulated to reduce pigment-related discoloration, with visible fading from the early sessions and a progressively more even and radiant skin tone.
Q: What is the difference between Rejuran black box and red box?
Both versions deliver similar skin restoration results — strengthening the skin, improving hydration, and promoting overall skin health. The key difference is the experience during injection.
- The red box (Rejuran HB) contains lidocaine and comes in 1 CC per box
- The black box (Rejuran) contains no lidocaine and comes in 2.7 CC per box.
Q: Can Rejuran be combined with other treatments?
A: Yes, Rejuran can be combined with other skin treatments without requiring a waiting period — with the exception of Juvelook Skinbooster, for which a gap of approximately 4 weeks is recommended, as both treatments work in a similar collagen-stimulating capacity, allowing the skin to recover optimally.
Q: What is the difference between Rejuran and Chanels?
A: Rejuran focuses on restoring skin from within using PN derived from salmon DNA — repairing weakened skin, improving structure, refining texture and pores, and promoting natural skin health.
Chanels is a Skin Booster that targets radiance and glow, nourishing the skin with key ingredients such as Pink Yeast, Peptide, and Hyaluron.
Rejuran suits those looking to rebuild skin strength from the inside, while Chanels program suits those seeking brighter, more luminous skin. Both can be used individually or in combination, based on the physician's assessment.
Q: Can I apply makeup after Rejuran? How long should I wait?
A: It is recommended to avoid makeup for 1 day after the injection to allow the needle marks to close, reduce irritation, and support faster skin recovery.
