Rejuran Alternatives in Korea | What Skin Booster Options Are Available?
Eugene Lee • November 2, 2025
What is Rejuran?
Rejuran is a Korean injectable “skin booster” built around
PDRN (poly-deoxyribonucleotide) derived from salmon DNA. It’s designed to help with skin regeneration, improving texture, elasticity, and barrier repair.
Its popularity comes from its ability to support collagen production and improve overall skin quality — not just volume.
Why Look for Alternatives?
- Maybe your skin goal isn’t purely regeneration but also hydration, brightening or volume.
- You might prefer a product with less downtime or different injection technique.
- You want to explore options that suit your budget, skin-type, or desired effect.
- Some clinics may offer newer formulations or “next-gen” boosters.
Notable Alternatives to Rejuran in Korea
Here are some strong contenders with slightly different profiles.
- Elreju – Marketed as a “4th generation skin booster” with PDRN + PN + hybrid hyaluronic acid. Good if you like the regeneration concept but want added hydration and less discomfort in injection.
- Juvelook – While not purely a “regeneration only” product, Juvelook combines HA + a collagen-stimulating polymer. It’s more focused on texture improvement, firmness and subtle volume.
- Kiara Reju – A Korean skin booster that combines PDRN + HA + niacinamide for skin tone, elasticity and barrier support.
- Exosome therapies & other skin booster cocktails are also popular alternatives (often mentioned in Korean clinics).
How They Compare – What to Ask Your Doctor
When comparing Rejuran vs these alternatives, keep these questions in mind:
- What is the main active ingredient (PDRN? PN? HA? combination?)
- What is the primary goal of this booster: regeneration? hydration? texture? volume?
- What is the injection technique being used: micro-droplet, mesotherapy, micro-cannula?
- What is the downtime and comfort level (some newer boosters emphasise less pain/discomfort)?
- What are the maintenance interval and cost of sessions?
- Does your skin type (thin skin, melanin-rich skin, sensitive skin) match the product profile?
My Take – Which One Might Be Right for You?
- If your skin goal is repair, barrier strengthening, subtle regeneration, then a PDRN-centric booster like Rejuran or Kiara Reju is a strong fit.
- If your skin goal is texture improvement, firmness, enlarged pores or early sagging, then something like Juvelook might be more relevant.
- If you’re concerned about comfort or downtime, newer boosters like Elreju might be worth considering.
- Always align the choice with your dermatologist’s assessment of your skin thickness, concern area, and the exact injection plan.
