Reference, not a process guide
Direct answer: This page defines terms used across the site in one place. It does not replace the document-review process in Formulation Document Review or the unit-comparison workflow in How to Compare Product Specifications — use those for process, use this for definitions.
Materials
| Term | Definition |
|---|---|
| PLLA | Poly-L-lactic acid — a biostimulator material supplied as a freeze-dried powder for reconstitution. Used in FRIDERM's Fri-Filler line (Fri Hydro, Fri Volume, Fri S, Fri X). |
| PDLLA | Poly-D,L-lactic acid — a related but chemically distinct polymer. Not interchangeable with PLLA in formulation or regulatory terms; comparing the two by name alone is not the same as comparing their actual formulations. |
| HA | Hyaluronic acid — a cross-linked gel filler material, supplied in syringe format in FRIDERM's FRIGGEL and related lines. |
| CaHA | Calcium hydroxylapatite — a mineral-based biostimulator material, used in HyaCaHAP and Innoshe. |
| PDRN | Polydeoxyribonucleotide — an ingredient used in some skin-booster formulations. |
| PN | Polynucleotide — a related but distinct ingredient term. PDRN and PN are not interchangeable; this site does not use them as synonyms. |
Procurement & business terms
| Term | Definition |
|---|---|
| MOQ | Minimum order quantity — the smallest quantity you can order for a given SKU or project type. See Order and Shipping Planning for current general reference figures. |
| Incoterms (EXW/FOB/CIF/DDP, etc.) | Standardized international trade terms defining who is responsible for which leg of shipping, insurance and duty. See Understanding Incoterms for a full explanation of each term. |
| CoA | Certificate of Analysis — a batch-specific quality document. See Quality & Documentation for how to request one. |
| IFU | Instructions for Use — the document accompanying a product describing its intended professional use. |
| OEM | Original Equipment Manufacturing — producing a product (or a variant of one) under your brand based on an existing specification. |
| ODM | Original Design Manufacturing — a new or substantially modified formulation/design developed for your brand, not just a relabel. |
| Private label | Selling an existing product under your own brand name and packaging, typically without a materially new formulation. |
| Check availability vs. in stock | "Check availability" means stock has not been verified recently enough to state as currently available; we do not display "in stock" without a verified check. See Wholesale & Ready Stock. |
FAQ
Are PLLA and PDLLA the same thing?
No. They are related but chemically distinct polymers. Treat any source that uses them interchangeably as imprecise, and ask for the specific material confirmed in writing.
Are PDRN and PN the same thing?
No. They are distinct ingredient terms and this site does not use them as synonyms. Confirm which one a specific product actually contains.
What's the difference between OEM and ODM?
OEM generally means producing an existing specification under your brand; ODM generally means a new or substantially modified formulation developed for your brand. See Private Label & OEM/ODM for how FRIDERM Pro currently scopes each.
