A recent systematic review published in the Journal of Cosmetic Dermatology highlighted statistically significant improvements in skin elasticity and hydration among patients treated with polynucleotide injections, reinforcing their value as transformative tools in regenerative aesthetics.
Among the most recognized treatments in this category are Plinest and Rejuran—both celebrated for their ability to stimulate tissue repair, boost collagen production, and restore a more youthful complexion. Their growing presence in cosmetic clinics signals a broader shift toward minimally invasive, science-driven approaches to skin rejuvenation.
In this article, we’ll compare Plinest vs Rejuran, diving into their formulations, mechanisms, and clinical uses to help practitioners make informed recommendations and guide patients with confidence.
Key Takeaways
- Plinest and Rejuran are both polynucleotide-based skin treatments designed to improve skin quality through cellular regeneration.
- Plinest uses trout-derived polynucleotides developed in Italy, focusing on hydration, elasticity, and collagen stimulation.
- Rejuran, originating in South Korea, uses salmon-derived polynucleotides to target tissue repair, making it especially suitable for acne scars and skin barrier restoration.
- The Plinest product range offers multiple variations tailored to different treatment areas, while Rejuran is currently offered primarily as Rejuran Healer.
- Plinest is ideal for early signs of aging and those seeking gradual rejuvenation, while Rejuran is better suited for patients needing intensive repair and regeneration.
- Choosing between the two depends on patient-specific needs, desired outcomes, and consultation with a qualified aesthetic professional.

Origins and Development of Plinest vs Rejuran Polynucleotides
Understanding the unique origins when comparing Plinest vs Rejuran treatments helps both practitioners and patients determine the most suitable aesthetic approach. Highlighting their innovative contributions to skin rejuvenation gives context to each product’s value in clinical practice.
Plinest employs polynucleotides extracted from trout DNA—a formulation developed in Italy around 2005. The Plinest treatment boosts hydration and enhances skin elasticity by stimulating collagen production and encouraging cellular repair. The result is a gradual yet natural revitalization of skin quality over time.
In contrast, Rejuran (also known as Rejuran Healer) utilizes salmon-derived polynucleotides. With origins in South Korea, it is widely used to accelerate skin repair and collagen restoration. This makes it particularly effective for issues like acne scars, fine lines, and uneven texture through improved cellular regeneration.
Polynucleotides have rapidly emerged as potent ingredients that benefit the skin, hair, and other soft tissues. While the sources and regional development differ, both Plinest and Rejuran trigger natural cellular recovery and offer tailored solutions in the field of regenerative aesthetics.
Molecular Composition Differences: Plinest vs Rejuran
When considering either option, aesthetic professionals must evaluate each product’s molecular profile and treatment mechanism. Unfortunately, while direct molecular comparisons are limited in published data, their composition and proprietary technologies do differ.
Plinest uses trout-derived polynucleotides and the patented Highly Purified Technology (HPT), optimizing hydration and structural regeneration. Rejuran, on the other hand, sources salmon-based polynucleotides and focuses on restoring the extracellular matrix.
Clinically, Plinest emphasizes collagen stimulation and hydration, while Rejuran prioritizes deep tissue repair. The Plinest product range also offers more targeted options for different skin needs, whereas Rejuran currently provides a singular skin-rejuvenating solution.
Clinical Indications and Treatment Areas for Plinest vs Rejuran
Although both treatments are gaining popularity, understanding their specific indications helps avoid inappropriate use and maximizes patient safety.
Plinest is primarily used for improving hydration, elasticity, and overall skin tone. It is well-suited for areas such as the face, neck, and décolletage—regions that benefit from collagen and elastin stimulation. The gradual effect leads to a natural, refreshed appearance.
Rejuran targets tissue regeneration more directly. It’s ideal for treating acne scarring, enlarged pores, and areas with significant skin barrier compromise. Commonly injected into the face and neck, Rejuran is often chosen when more intensive healing is desired.
Both offer unique benefits, but understanding their core strengths allows clinicians to tailor the approach more effectively.
Patient Profiles Best Suited for Plinest vs Rejuran Treatments
Patient suitability is critical for any regenerative treatment. Aesthetic professionals must perform thorough consultations to determine whether Plinest or Rejuran is a better fit for each individual’s needs.
- Plinest: Ideal for those beginning to experience age-related skin changes, including early fine lines and texture loss. It’s favored by patients who want progressive, subtle improvements with minimal downtime. Its gentle formulation makes it especially appropriate for delicate skin areas.
- Rejuran: More targeted for patients dealing with more pronounced dermal issues, such as post-acne scarring or deeper wrinkles. Its stronger regenerative effect makes it an excellent choice for those requiring structural repair and skin barrier restoration.
Conclusion
Ultimately, the decision between Plinest and Rejuran should reflect the patient’s skin condition, aesthetic goals, and desired rate of improvement. While both polynucleotide treatments enhance skin health and repair, they do so in distinct ways.
Plinest treatment offers a softer, hydration-focused regeneration process, ideal for early intervention and maintenance. Rejuran, with its more aggressive repair mechanism, is better suited for correction and recovery of damaged skin.
With proper consultation and informed guidance, practitioners can help patients choose the right polynucleotide therapy for lasting, visible skin rejuvenation.
FAQs
1. What is the primary difference in the source of polynucleotides between Plinest and Rejuran?
Plinest uses polynucleotides extracted from trout DNA, while Rejuran utilizes polynucleotides derived from salmon DNA.
2. What are the main benefits of Plinest and Rejuran treatments?
Plinest focuses on enhancing hydration and stimulating collagen production, which improves skin elasticity. Rejuran, on the other hand, emphasizes tissue repair and cellular regeneration, effectively addressing issues like acne scars and uneven skin texture.
3. Who is the ideal candidate for each treatment?
Plinest is best suited for patients with early to moderate signs of aging who seek gradual rejuvenation with minimal downtime. Rejuran is ideal for those with noticeable acne scarring or advanced tissue damage who require more intensive regenerative support.
