If you’re considering Rejuran Healer for skin rejuvenation in Korea, one of the most important questions to ask is: How long do the results last? While Rejuran is famous for its natural skin-regenerating effects, its timeline, duration, and maintenance routine are key to getting the best value and longest-lasting glow.
In this guide, we break down the Rejuran Healer results timeline, how long you can expect your skin to stay youthful, and the top maintenance tips from Korean dermatology clinics.
🧬 What Is Rejuran Healer?
Rejuran Healer is a PN (polynucleotide)-based injectable derived from salmon DNA. Unlike fillers or Botox, Rejuran works by stimulating your skin’s own repair mechanisms — especially fibroblast activity and collagen production — to restore youthful texture and elasticity over time.
