Rejuran versus Juvelook: which should you choose for pores and acne scars? Studies versus personal accounts
Full translation of the Korean article. Translation checked for completeness, numerical consistency and medical meaning; separate medical review of this translation is pending. Translation updated: 2026-10-28.
When choosing Rejuran or Juvelook for pores or acne scars, first distinguish enlarged-looking pores from depressed scars. Both treatments can be discussed for skin-quality improvement, but the studies reviewed cannot establish that one brand is better for every pore or scar concern. At SEOLREIM Clinic, show the physician the area and change you most want to address, and discuss separately the goals to assess with injections and structural scars requiring separate assessment for lasers, subcision or other approaches.
Check whether “pore improvement” in personal accounts matches what the study measured
Check three things before choosing. First, did the study address the same area as your concern? Second, was the comparison with another skin booster or with the pretreatment condition? Third, did the assessment measure hydration and texture or actual changes in depressed scars? A randomized split-face PN study compared PN with non-cross-linked HA around the eyes in 27 people and observed differences in some skin-quality measures. A pilot PDLLA/HA study assessed skin changes before and after repeated treatments in 16 people. These studies did not directly compare the two treatments, so their figures or satisfaction results cannot be combined to declare Rejuran or Juvelook the winner. Lighting, sebum, temporary swelling in pore photos and scar type also need separate assessment.
| Current concern | Goals to distinguish at a SEOLREIM consultation | What to check in studies and personal accounts |
|---|---|---|
| Enlarged-looking pores and rough texture | Changes in pore appearance, oiliness and texture | Do not apply eye-area measures directly to the entire nose or cheeks |
| Shallow fine lines and dryness | Distinguish skin quality and hydration from static wrinkles | Do not interpret immediate radiance as long-term remodeling |
| Depressed acne scars | Assess the structure of rolling, boxcar and ice-pick scars | Check whether a skin-texture study actually studied scar removal |
| Flat red or brown marks | Distinguish pigment and vascular changes from depressions | Scar injections do not replace treatment for every mark |
| Active acne or dermatitis | Prioritize medical care for inflammation and stabilization | Do not use the phrase “skin regeneration” to justify injecting inflamed areas |
Definitions and how the treatments work
Rejuran is a PN-based product family; Juvelook products contain PDLLA and non-cross-linked HA. Ingredient names or a shared reference to collagen do not mean identical actions, doses or indications. Skin-quality studies of PN and tissue-response studies of PDLLA/HA differ in products, injection methods and areas. Distinguish the exact product names, including Juvelook Skin versus Volume and different Rejuran products, and check Korean approved information and instructions for use.
Potential benefits and limitations
Gradual changes in texture, shallow fine lines and pore appearance may be expected, but one injection treatment does not address the depth, tethering and edges of every scar. Scars may require lasers, localized treatment, subcision or other approaches. Consider small sample sizes, different areas and follow-up periods; do not turn a small study reporting no adverse effects into a claim of no risk. Assess responses for each goal using photos under the same conditions and examination.
Who can seek a consultation and how suitability is assessed
Adults whose main goal is improved skin quality and who are considered suitable on examination may seek consultation. The physician distinguishes pores, scars, active inflammation and pigmented marks, and checks previous injection sites, products, dates and nodules; herpes, infection or dermatitis; pregnancy, breastfeeding, allergies and medications increasing bleeding risk. Do not choose a particular injection to treat inflammation simply because skin is sensitive or red.
Procedure, recovery and scheduling
Prepare unfiltered front and side photos, previous treatment records and the one or two concerns that bother you most for SEOLREIM. During consultation, establish target areas, product, actual amount, method, anesthesia, total cost and follow-up criteria. Raised injection bumps, swelling, bruising and tenderness vary by method and individual; neither product can be assumed always less painful or faster to recover from. Share departure and photography dates, and confirm instructions for washing, makeup and exercise and the actual scope of contact after returning home.
Side effects, contraindications and symptoms requiring medical attention
Besides redness, bruising and swelling, infection, persistent papules or nodules, inflammatory reactions, asymmetry and rare vascular complications are possible. Do not assume persistent nodules containing PDLLA can be immediately dissolved like HA filler. Worsening pain, pale or netlike skin discoloration or visual disturbances require immediate medical care; warmth, pus, fever or persistent lumps also need assessment. Do not choose solely by safety rankings in personal accounts.
Distinguish injection-treatment goals from treatment of scar structure
| Category | Role and goals | What to check |
|---|---|---|
| Rejuran PN | Individual goals such as skin quality and fine lines | Product, area, study comparator and actual injection plan |
| Juvelook PDLLA/HA | Gradual skin-quality improvement and adjunct goals for selected scars | Skin versus Volume, dispersion, nodule risk and follow-up |
| Lasers, subcision and other methods | Remodeling and assessment of tethering according to scar structure | Not every scar needs the same combination |
Questions and answers for a medical consultation
These questions for a consultation before visiting SEOLREIM are based on the literature. They are not a clinician interview or an individual prescription. This new article is awaiting confirmation of a separate review by a medical professional.
Q. Is Juvelook always better for pores?
A. Direct comparative evidence is insufficient to establish that. First align the cause of the pore-like appearance, target area and outcome measures in the evidence.
Q. Can the Rejuran eye-area study also be applied to depressed cheek scars?
A. The area and measured outcomes differ. Eye-area skin-quality measures do not directly prove improvement of deep acne scars.
Q. If I have one of these treatments, will scar lasers be unnecessary?
A. This depends on scar type, tethering and depth. Distinguish the roles of injections and structural treatment, and assess the response after the first stage.
Consultation with the SEOLREIM clinic director and signature programs
SEOLREIM Clinic applies its principles of consultation and treatment directly by the physician, genuine products, correct quantities and attentive care through goal-based diagnosis, product verification, recording actual amounts and follow-up consultation. Distinguish treatment roles for pores and texture from those for depressed scars; discuss related programs such as Silky Pore after confirming actual components and suitability. Program names or more injection procedures do not overcome limitations in the evidence.
Booking, languages, location and guidance for international visitors
Overseas visitors comparing Rejuran and Juvelook at Gangnam or Seoul dermatology clinics should first prepare their own areas of concern and previous responses rather than photos of desired results. After searching for a clinic near Gangnam Station or elsewhere in Korea, tell SEOLREIM your priorities among pores, depressions and dryness, dates in Korea and preferred language to request consultation and follow-up. SEOLREIM Clinic is on floor 11 of Gangnam8258 Building, 376 Gangnam-daero, Seoul, approximately 1 minute from Exit 3 of Gangnam Station. Use the KakaoTalk, Naver booking and telephone channels below for Korean-language consultations and bookings, and the International consultation link for visits from overseas. Provide the treatment of interest, skin concerns, dates in Korea, preferred language and whether interpretation is needed. Confirm the actual scope of language support, costs, booking confirmation and cancellation terms before visiting. Depending on the examination, same-day treatment may be unavailable or follow-up after returning home may be needed; also discuss how to report adverse reactions and the actual scope of aftercare.
