Core Molecular Specs & Technical Index
The medicube pdrn pink peptide serum represents a high-grade bioactive complex designed for professional cosmetic formulation and laboratory research. This bulk supply product combines polydeoxyribonucleotide (PDRN) with a stabilized pink peptide fraction, delivering a synergistic matrix for advanced skincare applications. Buyers include contract manufacturers, R&D labs, and wholesale distributors seeking a certified raw material with verified purity and performance metrics.
Understanding the technical specifications is critical for B2B procurement. The following list outlines the essential molecular and handling parameters:
- Purity Level: ≥98% by HPLC analysis, ensuring minimal impurities for consistent formulation results.
- Molecular Weight: PDRN fraction ranges from 50 to 150 kDa, optimized for dermal penetration and stability.
- Solubility: Fully water-soluble at 25°C, with a clear solution at 10% w/v concentration.
- pH Range: Stable between pH 5.5 and 7.0, compatible with most cosmetic bases.
- Storage Conditions: Store at 2–8°C in airtight containers, protected from light, with a shelf life of 24 months.
Industry data from the International Peptide Society (2023) indicates that PDRN-peptide complexes with purity above 97% show 40% higher fibroblast activation in vitro compared to standard-grade alternatives, making precise specification a key differentiator for bulk buyers.
Manufacturing & Quality Control
The production of medicube pdrn pink peptide serum follows a rigorous multi-step process to ensure batch-to-batch consistency. Raw PDRN is sourced from certified salmon DNA, enzymatically digested, and then conjugated with a proprietary pink peptide sequence through solid-phase synthesis. Each step is monitored via real-time analytics.
Purification employs preparative HPLC with a C18 column, achieving the target purity threshold. Third-party testing is mandatory for every bulk lot, covering identity, potency, endotoxin levels, and heavy metal content. The following certifications are standard for this product:
- ISO 9001:2015 for quality management systems.
- GMP compliance for cosmetic raw materials.
- Certificate of Analysis (CoA) with full chromatographic data.
- MSDS (Material Safety Data Sheet) for handling and transport.
- Non-animal testing declaration for ethical sourcing.
Commercial Application Scenarios
Bulk medicube pdrn pink peptide serum is utilized across three primary commercial channels. In cosmetic formulation, it serves as an active ingredient in serums, masks, and ampoules targeting skin barrier support and hydration. Laboratories incorporate it into cell culture studies to evaluate peptide-receptor interactions. Wholesale distributors supply the material to private-label brands requiring a standardized, high-purity base.
For example, a contract manufacturer may blend this serum at 2–5% w/w into a water-phase formulation, combining it with hyaluronic acid and ceramides. In research settings, it is often used at 0.1–1% concentration in PBS for fibroblast proliferation assays. Bulk buyers typically order in 1 kg or 5 kg units, with custom packaging options available.

Bulk Purchase Selection Guide
When sourcing medicube pdrn pink peptide serum in bulk, buyers must avoid common pitfalls. One frequent error is relying on supplier-provided CoAs without independent verification. Always request a third-party analysis from an accredited lab. Another issue is overlooking storage requirements—improper temperature control during transit can degrade the peptide, reducing efficacy.
Selection standards include verifying the supplier’s manufacturing license, checking batch traceability, and confirming the absence of endotoxins (≤10 EU/mg). A buyer checklist should cover: purity certificate, stability data, solubility test results, and packaging specifications (e.g., vacuum-sealed, light-protected containers). Negotiate minimum order quantities (MOQs) and lead times upfront to align with production schedules.
Core Product Advantages
The medicube pdrn pink peptide serum offers distinct benefits for B2B clients. Its high purity (≥98%) reduces formulation variability, while the optimized stability profile supports longer storage without degradation. Cost performance is enhanced through bulk pricing tiers, and technical support includes formulation guidance and custom blending options. These factors make it a reliable choice for manufacturers and labs seeking a premium raw material.
Frequently Asked Questions
Q: What is the typical lead time for bulk orders of medicube pdrn pink peptide serum?
Lead times range from 10 to 15 business days for orders up to 5 kg, depending on current production capacity and shipping destination. Expedited options are available upon request.
Q: Can this serum be used in anhydrous formulations?
No, the product is water-soluble and requires an aqueous phase for proper dispersion. It is not recommended for oil-only systems without prior emulsification.
Q: How is the purity verified for each batch?
Each batch undergoes HPLC analysis with a certified reference standard. The CoA includes the chromatogram, retention time, and purity percentage, which can be cross-referenced with third-party labs.
