HA vs PLLA vs CaHA vs PN: TOP-Q Material Classes Explained

HA vs PLLA vs CaHA vs PN: TOP-Q Material Classes Explained

Search results for this catalogue tend to contain abbreviations rather than questions: caha, plla, pn booster, pn skin booster, deep line. Someone has seen a product name or a photograph of a box and wants to know how the items relate. The short answer is that the TOP-Q® range has two independent axes: the material class a product belongs to, and the line or presentation within that class. Separating them early saves a round of corrections on quotations and artwork.

This page deals with the material-class axis. It covers the products behind each abbreviation, their catalogue pages and the documents that belong to each class. It does not describe mechanisms of action, treatment protocols, indications, clinical results, or how long any product lasts. Use-related questions belong with a qualified professional and the current instructions for use (IFU) for the market in question.

1. Four material classes in the TOP-Q® catalogue

Category label	TOP-Q® products under it	Typical format	Where to start
Hyaluronic acid dermal filler	Fine Line, Derm Line, Deep Line, Ultra Deep, Red Lips, 10 ml / 20 ml, 50 ml	1 ml pre-filled syringes plus larger-volume formats	Full product range
Collagen Stimulator — PLLA	PLLA 5 ml	5 ml vial	PLLA 5 ml product page
Collagen Stimulator — CaHA	CaHA 1 ml	1 ml presentation	CaHA 1 ml product page
Skin Booster — PN	PN Booster	1 ml and 2 ml presentations	PN Booster product page
Joint Injection	Non-cross-linked sodium hyaluronate gel	Specification-only page	TOP-Q Knee Injection

The HA axis has many lines inside it, while the PLLA, CaHA and PN entries are each comparatively narrow. If you arrived from a search for fine line fillers or filler ultra deep, the line-specification guide explains those names. If you arrived from caha, plla or pn booster, the sections below are about the products and documents behind each abbreviation.

2. A class label is a filing label, not a performance claim

It is tempting to read “Collagen Stimulator” or “Skin Booster” as a statement about what a product does in tissue. In this catalogue it is a grouping label: it tells you which set of product pages, specification sheets and IFUs to open. We use it so a buyer can find the right document set, and we deliberately do not expand it into mechanism descriptions, comparative performance statements or outcome claims.

Three practical consequences:

• Do not treat a category name as a shared specification. Two suppliers can file products under the same label with different formulations, containers and document sets.
• Do not reverse-engineer our specifications from another catalogue. A concentration, particle size or component list on a competitor’s sheet describes their product, not ours.
• Do not assume a label carries across markets. Regulatory classification and permitted labelling wording vary by destination; the IFU and market-approved artwork are the references.

3. The products behind each abbreviation

HA — hyaluronic acid dermal fillers. The largest group in the range. The facial lines (Fine Line, Derm Line, Deep Line, Ultra Deep) are 1 ml presentations; Red Lips is a dedicated lip presentation; the 10 ml / 20 ml and 50 ml pages describe separate large-volume products with their own SKUs. Each has its own specification sheet.

PLLA. Our PLLA product is listed as PLLA 5 ml, a 5 ml vial presentation under the Collagen Stimulator category. plla and top q plla are common bare search terms; the product page is where the exact name, container and document revision are confirmed.

CaHA. CaHA stands for calcium hydroxylapatite — in Italian catalogues you may see idrossilapatite. Our CaHA 1 ml page is the 1 ml presentation in the same Collagen Stimulator category. caha and filler caha point to this abbreviation; they do not identify a specific product until the SKU is named.

PN / Skin Booster. PN refers to the polynucleotide-based skin booster entry, listed as PN Booster in 1 ml and 2 ml presentations. Searches for pn booster and pn skin booster usually want this page. Confirm which volumes are available for your market on the product page and in the quotation.

Non-cross-linked sodium hyaluronate gel. The knee injection page is a specification-only listing for licensed professional and distributor channels, with a professional-channel disclaimer. It sits outside the HA dermal filler lines.

4. Which documents belong to each class

The core pack is the same for every item — specification sheet, IFU, labelling artwork, lot traceability information and the certificates that actually exist. What changes is the set of fields worth reading first.

Class	Fields to read first
HA dermal filler lines	HA concentration in mg/ml, cross-linking information, gel and particle characterisation, declared fill volume, box contents
PLLA 5 ml	Container type, declared contents per vial, packaging unit, IFU preparation wording
CaHA 1 ml	How the particulate system is characterised, declared volume, presentation, lot marking
PN Booster	Declared components on the current IFU, available volumes, unit and carton presentation
Large-volume HA	Declared volume versus packaging unit, carton configuration, separate SKUs

Notice what is absent: durations, efficacy comparisons, treatment schedules and safety conclusions. Those are not fields we publish in a sourcing guide. Documents are issued per product, not per class — request the pack for each SKU you intend to order, with revision dates.

5. How the two axes fit together

A common mistake is to treat “HA” and “Deep Line” as competing choices. They are not: HA is the material class, Deep Line is a presentation inside it. Likewise, PLLA 5 ml and CaHA 1 ml share a category label but are two separate products with separate pages, SKUs and document sets.

If you only know an abbreviation, start from the full product range, match it to a class, then open the product page and note the exact name and SKU. The OEM and private-label page describes how own-brand artwork is reviewed per SKU; the distributor page explains how supply enquiries are handled. There is no online checkout — quotation and sample requests come through the contact route.

6. What we state and what we do not

We hold CE and ISO 13485 documentation issued by domestic certification bodies, and current files are available on request. We describe them as documentation available on request, not as EU notified-body certification, and not as automatically accepted in every market. Acceptance is a question for the destination market’s rules and your own adviser.

We also do not publish unsubstantiated experience claims, clinical outcome data, indication lists or efficacy and duration figures. Product pages, specification sheets and the IFU are where technical fields live, and the current dated version wins over any summary page.

Frequently asked questions

Is PLLA a hyaluronic acid filler?

No. PLLA 5 ml sits in a separate category with its own product page, specification sheet and IFU. The same applies to CaHA 1 ml and PN Booster.

What does CaHA stand for?

Calcium hydroxylapatite. In Italian-language catalogues the term idrossilapatite is sometimes used for the same material. Our CaHA 1 ml page is the product reference.

What is a PN skin booster?

In our catalogue it is the PN Booster entry, available in 1 ml and 2 ml presentations. The category label is a filing term; the product page and IFU carry the declared components.

Which class is “better”?

We do not make comparative performance or outcome claims. The class label helps you find the right documents; the choice for a given market depends on the approved IFU and your own product plan.

Can I get one document pack covering all classes?

No. Documents are issued per product. Request the pack for each SKU, with revision dates, and check the IFU and artwork against your destination market.

Where do I start if I only know the abbreviation?

Open the product range, match the abbreviation to a class or line, then request the current specification sheet for that SKU with your market and labelling requirements.
