Under-Eye Rejuran vs. Juvelook vs. Sculptra

🎯 Under-Eye Rejuran vs. Juvelook vs. Sculptra: Which Works Best?

If you’re exploring under-eye treatments in Korea and trying to decide between Rejuran, Juvelook, and Sculptra, here’s a detailed breakdown of how each works, ideal uses, pros & cons — plus a quick comparison to help you decide.

🧬 How Each Treatment Works

  • Rejuran: Uses polynucleotides (PDRN) to boost skin repair, strengthen the under-eye skin barrier, and improve texture. It’s more about skin quality than volume.
  • Juvelook: Combines hyaluronic acid (HA) with poly-D, L-lactic acid (PDLA) in a skin-booster format — so it offers both hydration and some structural collagen stimulation.
  • Sculptra: Poly-L-lactic acid (PLLA) — a deeper collagen stimulator used for volume loss, structural support and facial scaffold rebuilding. Takes longer to show full effect but lasts longer.

✅ Best Use Case for Under-Eye Area

🕒 Timeline & Longevity

  • Rejuran: Results appear faster (4-8 weeks), lasting ~6–12 months.
  • Juvelook: Results visible ~6–12 weeks, moderate longevity (depends on dose & area).
  • Sculptra: Slower onset (~3–6 months full effect), but longer lasting (12–24+ months) if done correctly.

👍 Pros & Cons

Rejuran

  • Very good for skin texture, thin skin correction.
  • Minimal volume change — stays subtle.
    − Not designed to fill large hollows.

Juvelook

  • Offers hydration + some lift.
  • Good middle ground.
    − Less depth of structural support than Sculptra.

Sculptra

  • Strong collagen boost → structural improvement & volume.
  • Great for deeper hollows.
    − Slower to manifest results; more risk of overcorrection if not done carefully under eyes.

🧠 Which One Should You Pick?

  • If your main concern is thin under-eye skin, dark circles due to skin quality, mild hollowness → go for Rejuran.
  • If you want improved texture + slight support, but not major hollowness correction → Juvelook might be ideal.
  • If you have significant volume loss, deeper hollows, tear-troughs, then Sculptra (or a combined approach) is more suitable.
  • Often the best approach is layered: start with skin quality (Rejuran), then structure (Juvelook or Sculptra) depending on your anatomy.

⚠️ Things to Check & Ask Before You Proceed

  • Ensure the clinic shows under-eye cases for each treatment in similar age/skin type.
  • Confirm dose, number of sessions and expected timeline.
  • Ask about downtime, swelling, risk of bumps or nodules (especially with Sculptra). Primi clinic
  • Under-eye area has critical vascular anatomy — make sure injection by experienced doctor.
  • Understand cost vs sessions: cheaper upfront may mean more top-ups later.

📝 Summary

  • Choose Rejuran if you want skin-quality improvement rather than volume.
  • Choose Juvelook if you’re in between: want glow + mild correction.
  • Choose Sculptra if you need structural correction of hollow under-eyes with volume loss.
  • Ask about combination therapy because in many Korean clinics, layering produces the most natural, balanced result.

Under Eye Hollow & Dark Circle Treatments in Korea: Complete Guide Dark circles and under-eye hollowness are among the most common concerns for both Koreans and international patients visiting Seoul. Whether caused by genetics, aging, lack of sleep, volume loss, or pigment issues, Korea offers some of the most advanced and effective solutions—non-surgical, minimally invasive, and tailored to each specific cause. This complete guide explains why dark circles happen , how Korean clinics treat them , the best treatment options , and what to expect before and after care . 1. Why Dark Circles & Under Eye Hollows Happen A. Volume Loss (Under-Eye Hollowing / Tear Troughs) As you age, the fat under your eyes decreases, causing a sunken look and shadows. B. Pigmentation Brown or gray discoloration that stays even when you lift the skin. C. Thin Skin The skin under the eyes is very thin, revealing bluish veins. D. Vascular Shadows Purple or bluish tone caused by visible blood vessels. E. Fat Herniation (Eye Bags) Puffy fat pads push forward, creating strong contrast and shadowing. F. Lifestyle & Genetics Stress, allergies, lack of sleep, and hereditary factors can worsen the look. Korean dermatologists diagnose the exact type first—because different causes require different treatments. 2. Korean Treatment Options for Under Eye Hollows & Dark Circles Korea stands out because clinics use multi-layered, combination approaches rather than one single treatment. Here are the top options used in Seoul. 1. Under Eye Filler (Tear Trough Filler) Perfect for hollowness , shadowing, and volume loss. How it works Soft HA filler is placed under the tear trough to lift shadows and smooth the under-eye.

RF + Ultrasound Tightening (InMode, Thermage Eyes, Ulthera Eyes) How it helps Tightens loose skin Reduces fine lines Improves mild eye bags Best for Aging under-eye skin Mild sagging 6. Fat Repositioning or Under-Eye Fat Removal (Surgery) For patients with eye bags , puffiness, or severe fat herniation. Benefits Long-lasting improvement Removes shadows caused by bulging fat More dramatic correction than filler Best for Puffy eye bags Mixed dark circles + excess fat Korea is globally known for this procedure due to precision and natural results. 7. PRP / Exosome Under-Eye Therapy For improving skin quality, collagen, and brightness . Benefits Regenerates under-eye skin Brightens and smooths tone Works well with lasers or fillers 3. Which Treatment Is Right for You? ✔ Hollow / Sunken Eyes → Tear trough filler → Fat grafting (for long-lasting results) ✔ Brown or Gray Pigmentation → Pico laser → Toning laser ✔ Blue or Purple Darkness → Rejuran I → Vascular laser ✔ Puffy Eye Bags → Under-eye fat repositioning → LDM + RF tightening ✔ Thin Crepey Skin → Rejuran I → Exosomes → LDM therapy ✔ Mixed Causes (Most Common) → Combination treatments (Korean approach) → Example: Filler + Rejuran + Laser A proper Korean consultation typically identifies multiple contributing factors and creates a custom plan. 4. How Long Do Results Last? Depends on the treatment: Filler: 9–18 months Rejuran I: 6–12 months (series of 2–3 recommended) Lasers: Long-term with maintenance Exosomes / PRP: 6–12 months Fat repositioning surgery: Permanent RF/HIFU tightening: 6–12 months 5.
