Hyaluronic Acid (Sodium Hyaluronate) cannot perform effectively as an omnipotent moisturizer under a monolithic molecular weight. In conventional cosmetic chemistry, standard high-molecular-weight hyaluronic acid (>1,500 kDa) creates an imperceptible non-occlusive film on the stratum corneum surface. While this mechanism reduces immediate Transepidermal Water Loss (TEWL), it provides zero deep-tissue cellular hydration and fails to stimulate internal glycosaminoglycan synthesis.
As a leading OEM/ODM Hyaluronic Acid Serum exporter, Guangzhou Cairas Beauty utilizes proprietary multi-fractionated, oligomeric hyaluronic acid chemistry. By dividing the active spectrum into a targeted 4D to 8D molecular matrix, our formulations achieve multi-depth physiological hydration:
| Molecular Grade | Dalton Weight (kDa) | Targeted Skin Layer | Physiological Mechanism & Benefit |
|---|---|---|---|
| Sodium Hyaluronate Crosspolymer | > 3,000 kDa | Stratum Corneum External Layer | Creates a breathable 3D hydration network, binding 5x more atmospheric water than standard HA; protects against particulate matter. |
| High Molecular Weight (HMW) | 1,500 – 1,800 kDa | Superficial Stratum Corneum | Forms a viscoelastic moisture shield, dramatically lowers acute TEWL, and delivers immediate surface skin smoothing. |
| Medium Molecular Weight (MMW) | 200 – 400 kDa | Stratum Granulosum & Spinosum | Replenishes intermediate cellular spaces, stabilizes natural lipid envelopes, and facilitates water transport between cells. |
| Low Molecular Weight (LMW) | 10 – 50 kDa | Stratum Basale | Triggers natural pro-collagen peptide production, helps reduce inflammation, and restores skin firmness. |
| Oligo-HA / Hydrolyzed HA | < 5 kDa (Mini HA) | Dermis (Microvascular Level) | Crosses deep skin junctions, stimulates endogenous hyaluronic acid synthesis, and helps rebuild damaged micro-vessels. |
To avoid the common "pilling" and sticky skin-feel seen in low-quality hyaluronic acid products, Cairas uses high-shear microfluidization. This breaks down surface tension without using harsh petrochemical solvents, giving brands a fast-absorbing, silky serum that leaves a smooth finish under makeup.
B2B cosmetic buyers face rapid changes in regional rules, eco-packaging laws, and ingredient trends. Successful beauty brands are shifting away from single-ingredient marketing toward clinically supported, multifunctional barrier formulas.
Pure HA serums are evolving into multi-active complexes. Global brands now pair micro-HA with PDRN (Salmon DNA), Centella Asiatica (Cica), and stabilized Vitamin C to deliver both deep hydration and barrier repair in a single SKU.
Procurement teams are moving away from traditional plastic dropper bottles. The fastest-growing packaging requests are for PCR (Post-Consumer Recycled) glass, lightweight aluminum containers, and airless vacuum pumps that protect preservative-free formulas.
Cross-border exporters must meet tougher international standards. Importers need full factory audit transparency, including Intertek factory verification, EU CPNP dossiers, and US MoCRA safety data, to prevent customs hold-ups.
Founded in 2009, Guangzhou Cairas Beauty Products Co., Ltd. has grown from a specialized formulation laboratory into an internationally verified OEM/ODM cosmetics factory. Covering 12,180 m² of modern cleanroom workshops, we deliver scalable skincare manufacturing for brand owners, clinical chains, and global cosmetic importers across North America, Western Europe, Oceania, and Southeast Asia.

Every batch of Hyaluronic Acid serum goes through strict testing before export. Our facility uses advanced vacuum homogenizers, reverse-osmosis water purification (delivering conductivity under 1.0 µS/cm), high-speed aseptic filling systems, and in-house microbiological incubation rooms. We test every production run for pH consistency, viscosity limits, centrifugal stability, and heavy-metal traces.
Turnkey Export Support: We handle the entire supply chain under one roof—from formula formulation and bottle selection to label printing and shipping. We support FOB, CIF, and door-to-door DDP air and sea freight, along with complete COA, MSDS, and batch documentation to make importing straightforward.
Clear, direct answers for cosmetic brand managers, buyers, and sourcing specialists.
Talk directly with our formulation chemists and OEM project managers. We will review your target claims, packaging ideas, and volume targets, and deliver custom lab samples along with transparent factory quotes within 24 hours.
