Choosing a Filler by Area: Lines, Folds and Volume — A Specification Guide
Searches for “the best filler” usually assume there is one product that outranks all the others. In practice, a catalogue of fillers is a set of different specifications: gels of different texture, supplied in different volumes, with different packaging and documentation. The useful question is not which product is best in the abstract, but which specification matches the requirement you have been given — and whether the supplier can document it.
This guide is a product-selection reference for distributors, clinic buyers and private-label partners. It does not recommend treatments, describe injection techniques, compare clinical outcomes or make claims about duration or efficacy. Permitted use is defined by the approved labelling and Instructions for Use (IFU) in each market, and clinical decisions belong with licensed professionals.
1. Start from the specification, not the promise
Three parameters do most of the work when you compare presentations:
- Gel texture and cross-linking character — how the gel is built and how it behaves. Lighter gels and denser gels are different materials, not good and bad versions of the same material.
- Fill volume — 1 ml and 2 ml syringes are common for facial presentations; 10 ml, 20 ml and 50 ml presentations exist for large-volume body products. Volume is a packaging decision, not a measure of strength.
- Presentation and box contents — syringe or vial, what accessories are included, how the lot number and expiry appear on primary and secondary packaging.
Any page that promises a specific “lift”, a specific number of months or a guaranteed aesthetic outcome is making a claim that belongs in regulated documentation. We deliberately do not make those claims. A supplier who cannot show the specification sheet, IFU and labelling artwork for the exact lot to be shipped is a bigger risk than a supplier with a modest product range and complete paperwork.
2. A practical presentation matrix
The table below maps catalogue categories to specification characteristics. It is a way to read our range, not a treatment guide, and the product names are catalogue names rather than indications.
| Requirement described by the buyer | Catalogue category | Specification characteristics | Page |
|---|---|---|---|
| Lightest texture in the HA line | Fine Line | Light gel, small-volume syringe | Specs |
| Mid-range HA presentation | Derm Line | General-purpose HA gel | Specs |
| Firmer HA presentation | Deep Line | Denser gel character | Specs |
| Densest gel in the HA line | Ultra Deep | Highest-density HA presentation | Specs |
| Dedicated lip presentation | Red Lips | Lip-specific SKU | Specs |
| Mid-volume body presentation | 10 ml / 20 ml Body Filler | Localised-volume format | Specs |
| Largest-volume body presentation | 50 ml Body Filler | High-volume format | Specs |
Two notes on reading this matrix. First, the 10/20 ml and 50 ml pages describe different products, not two sizes of the same page — they were rewritten separately so that each has its own content, imagery and internal links. Second, the four HA facial lines are a range, and a first order is usually built by choosing which presentations your market actually requests, not by taking all of them.
You can see the whole catalogue on the products page.
3. Where HA ends and other material classes begin
A portfolio is not only HA. Three other classes in our catalogue have their own specification sheets and should never be compared on HA concentration:
- PLLA 5 ml — poly-L-lactic acid, a collagen-stimulator class supplied in a 5 ml presentation.
- CaHA 1 ml — calcium hydroxylapatite, a particulate system with a different data sheet.
- PN Booster — a polynucleotide skin-booster category.
There is also a non-cross-linked sodium hyaluronate gel in the catalogue. That page lists specifications and supply information only; it is intended for licensed professionals and authorised distributors and carries a professional-channel disclaimer.
If you are writing a purchasing specification, list each material class separately and request a separate document set for each. Mixing them into one “anti-aging filler” comparison produces exactly the kind of vague, uncheckable claim that makes a technical file weak.
4. The documentation checklist before an order
For every line you intend to carry, ask for the following in writing:
- Specification sheet for the exact presentation, including concentration, gel characterisation and fill volume.
- IFU and approved labelling artwork for the destination market.
- Certificate copies with the issuing body and scope stated plainly.
- Lot traceability: how lot and expiry are printed on syringe and carton.
- Declared storage and transport conditions, and who maintains them in transit.
- Carton contents and minimum order unit.
- For private-label projects: which packaging and documentation elements can be adapted, and which are fixed by regulation.
On certificates specifically: our CE and ISO 13485 documentation is issued by domestic certification bodies and is available on request. We do not represent it as an EU-notified-body certificate or as automatically recognised in every country. Recognition and product regulatory status vary by market, so your own regulatory adviser should review the pack before you commit.
Send the list to our team through the contact page and we will return the current documentation set. If you also need company background, the About TOP-Q® page covers the manufacturing entity and product scope.
5. Common purchasing mistakes
Choosing on a single number. Concentration or volume alone does not describe a gel. Ask for the full specification sheet.
Copying a competitor’s catalogue wording into your own. Terms such as “lidocaine”, “cannula included” or a specific mg/ml figure must be verified against your own product’s documentation, not inferred from another brand.
Treating product names as indications. They are SKU names. Approved uses live in the labelling and IFU.
Skipping the 15-language question. If you distribute in several markets, check whether the labelling, IFU and translations available for a product match the countries you will actually sell in. Our site publishes 15 language versions, but local regulatory documentation is a separate matter.
Frequently asked questions
Which filler is “the best” for deep lines or cheek volume? There is no product-level answer to that on a website. The right specification depends on the requirement, the market’s approved labelling and the professional’s assessment. We publish specifications, not treatment recommendations.
Do you state how long results last? No. We do not publish duration, efficacy or clinical-outcome figures on product pages. Such information must come from approved documentation for a specific product and market.
Can I order a mixed first shipment across lines? Commercial terms, minimum order units and available presentations are handled per enquiry — request a quote with the list of lines you need.
Are the 10/20 ml and 50 ml pages the same product? No. They are separate presentations with separate content, specifications and internal links. See both pages above.
Do you sell to individual consumers online? No. This is an inquiry-based wholesale and professional site with no online checkout or retail pricing.
