This guide provides a professional overview of Rejuran S and Rejuran I, two specialized polynucleotide-based products from Pharma Research. Intended for clinic owners, aesthetic physicians, and resellers, this article details their composition, distinct applications, and considerations for professional sourcing. Understanding these products is key for informed procurement decisions for your practice.
Understanding Rejuran S and Rejuran I Formulations
Rejuran S and Rejuran I are distinct polynucleotide (PN) formulations developed by Pharma Research in South Korea. Both products are based on salmon-derived DNA fragments, processed to specific chain lengths for their intended professional applications. The core difference lies in their viscosity and concentration, which dictate their suitability for various anatomical areas and tissue concerns.
Rejuran S features a higher viscosity, designed for more specific applications requiring a thicker formulation. In contrast, Rejuran I presents a lower viscosity, tailored for areas demanding finer product handling. These properties are critical for professionals when selecting the appropriate product for specific client needs and procedural requirements. For clinics exploring the broader range of skinbooster and biostimulator options, understanding such product variations is essential.
Polynucleotide Mechanism for Biostimulation
The active component in both Rejuran S and Rejuran I is polynucleotide (PN), a form of polydeoxyribonucleotide (PDRN). These biomolecules are known in professional contexts for their role in supporting tissue regeneration. When introduced, PNs are understood to facilitate an environment conducive to cellular processes, which is a key aspect of their professional application in aesthetic medicine.
This biostimulatory action is distinct from volumizing fillers; PNs aim to support natural skin processes. Professionals often consider products with similar biomimetic approaches, such as AMI Eyes, which also utilizes polynucleotides for delicate areas, reflecting a broader trend in aesthetic product development.
Professional Applications and Product Suitability
Rejuran S is formulated with a higher concentration and viscosity, making it suitable for professionals addressing specific concerns like depressed acne scars or deeper structural imperfections. Its denser consistency supports targeted application within such areas.
Rejuran I, with its lower viscosity, is designed for delicate areas requiring a finer product. Professionals commonly consider Rejuran I for concerns around the periorbital region, including fine lines and textural irregularities. Proper professional assessment is crucial for selecting the appropriate Rejuran variant based on the specific anatomical area and the client's tissue characteristics. This requires a precise understanding of each product’s rheological properties.
Product Presentation and Professional Handling
Rejuran S and Rejuran I typically come supplied in pre-filled syringes, ensuring sterility and precise dosing for professional use. Each syringe is designed for single-patient application.
Key considerations for professionals include:
- Storage: Products should be stored according to manufacturer guidelines, typically in a cool, dark place within specified temperature ranges to maintain product integrity.
- Preparation: While pre-filled, adherence to aseptic techniques during handling and preparation is paramount to ensure patient safety and product efficacy.
- Expiration: Always verify the expiration date on each package before use.
Professional handling guides, such as the one for Restylane Defyne, offer comparable insights into best practices for injectable aesthetics.
