What is Rejuran? The Skin-Healing Korean Treatment Everyone’s Talking About
05.03.2025

If you’re looking for a treatment that repairs, hydrates, and rejuvenates your skin from within, Rejuran might be the ultimate skin solution. This Korean skin-healing injectable is gaining global attention for its ability to boost collagen, improve elasticity, and strengthen the skin barrier—all with minimal downtime.
Korea is at the forefront of skincare innovation, continuously pioneering advanced treatments that deliver real, science-backed results. Known for its cutting-edge formulations and commitment to skin health, Korean aesthetics lead the way in developing technologies like Rejuran, which harnesses the power of polynucleotides (PN) to repair and regenerate the skin at a cellular level. This groundbreaking approach not only enhances hydration and resilience but also promotes long-term skin rejuvenation, making it a favorite among those seeking a naturally youthful glow.
What is Rejuran and How Does It Work?
Rejuran is an injectable skin booster made from polynucleotides (PN), derived from salmon DNA. These naturally occurring molecules help to repair and regenerate skin at a cellular level, making it more resilient, hydrated, and youthful over time.
Unlike traditional dermal fillers that add volume or Botox that relaxes muscles, Rejuran works by stimulating collagen production, improving skin texture, and accelerating skin healing—making it perfect for those looking for long-term skin rejuvenation rather than instant but temporary results.
Benefits of Rejuran
- Repairs damaged skin – great for sun damage, fine lines, and acne scars
- Boosts collagen production – improves elasticity and firmness
- Deeply hydrates the skin – restores moisture for a plumper, dewy complexion
- Strengthens the skin barrier – improves resilience to environmental stressors
- Smooths fine lines and wrinkles – creating a youthful, refreshed look
- Minimal downtime – mild swelling and redness subside quickly
Who is Rejuran For?
Rejuran is ideal for anyone looking to enhance their skin’s natural healing process. It’s especially beneficial for those who have:
- Aging skin with fine lines and loss of firmness
- Dull, dehydrated skin that lacks glow
- Acne scars or uneven texture needing repair
- Sun-damaged skin in need of deep rejuvenation
- Preventative skincare goals to future-proof skin aging
What to Expect from a Rejuran Treatment?
The treatment involves micro-injections placed across the face, stimulating the skin to regenerate and rebuild collagen naturally. Most clients experience minimal downtime, with some redness and swelling that fades within a day or two.
Results appear gradually, with optimal improvement seen over 4-6 weeks as the skin continues to repair itself. A course of 3-4 sessions, spaced a month apart, is recommended for long-lasting benefits.
Why is Rejuran So Popular?
As part of the Korean beauty movement, Rejuran is loved for its natural, long-term results. Rather than offering a quick fix, it focuses on deep skin healing and regeneration, making it a top choice for those seeking healthier, stronger skin over time.
Why is Rejuran So Popular?
One of the most exciting uses of Rejuran is for the under-eye area, where the skin is thinner and more prone to fine lines, dark circles, and loss of elasticity. Rejuran I (a more refined version of Rejuran) is specifically designed for treating this delicate area, offering benefits such as:
- Smoother under-eyes – reduces fine lines and crepey skin
- Brighter, more refreshed look – helps to improve dark circles by strengthening skin structure
- Tighter, firmer skin – restores elasticity and reduces sagging
- Natural, long-lasting results – enhances skin quality over time instead of just masking concerns
Unlike dermal fillers, which add volume, Rejuran I works by regenerating and strengthening the skin, making it a great option for those wanting a natural approach to rejuvenating tired-looking eyes.
Rejuran® Eye is a specialised bio-regenerating injectable treatment designed to repair, hydrate, and restore the delicate under-eye area. Formulated with polynucleotide (PN) extract from Wild Salmon DNA, this treatment stimulates collagen production and accelerates skin healing to reduce dark circles,...
