Fine vs Derm vs Deep: Understanding the TOP-Q Filler Lines
The TOP-Q® hyaluronic acid dermal filler range includes four 1 ml facial products with different catalogue names: Fine Line, Derm Line, Deep Line and Ultra Deep. They are not the same filler under four labels — each line has its own specification sheet, packaging and SKU. This guide explains what the names mean, where each product sits in the catalogue, and how to identify the right item when browsing or requesting a quotation.
Searches such as fine line fillers, derm line, deep line and filler ultra deep usually come from someone who has seen a box or a product page and wants to know how the lines relate. This page answers that narrow question. It is a product-naming guide, not a treatment guide: we describe product identifiers, presentations and documents, and we do not give treatment advice, list indications, or make claims about clinical results or duration. Use-related questions belong with a qualified professional and the current instructions for use supplied with the product.
1. The line names are catalogue identifiers
Fine Line, Derm Line, Deep Line and Ultra Deep are names TOP-Q® uses to separate presentations within one hyaluronic acid range. They are not industry-standard grades. Other manufacturers use different words — “soft”, “medium”, “volume” — and the same word on two catalogues rarely means the same thing.
Each name points to a specific dermal filler with its own specification sheet and SKU. That is why the line name matters: it tells the sales team which document set and which packaging configuration belong to an enquiry.
2. The four HA facial lines at a glance
| Catalogue line | Where it sits in our range | Specification page |
|---|---|---|
| Fine Line | Lightest presentation in the 1 ml HA facial line | Fine Line dermal filler |
| Derm Line | Mid-range 1 ml HA presentation | Derm Line dermal filler |
| Deep Line | Firmer 1 ml HA presentation | Deep Line dermal filler |
| Ultra Deep | Densest presentation in the HA line | Ultra Deep dermal filler |
All four are cross-linked hyaluronic acid gel presentations supplied in pre-filled syringes. Specification values can change with packaging configuration or document revisions, so the authoritative version is always the current dated specification sheet for the line you intend to order — not a cached PDF or a summary page.
3. What each line is, in product terms
Fine Line. The entry presentation in the 1 ml HA facial range. Its product page carries the current specification sheet, box contents and SKU. Readers searching fine line fillers or fine line injections are usually looking for this page.
Derm Line. The mid-range presentation. Same 1 ml format family, different specification and SKU. Its page is the reference for the declared HA concentration, gel characterisation and carton configuration.
Deep Line. A firmer presentation in the same range, again with its own sheet and SKU. deep line is a catalogue term that appears in search results without any brand context, so the product page is where you confirm which manufacturer’s line it is.
Ultra Deep. The densest presentation in the HA facial line. Its product page documents the presentation, packaging unit and documentation set. filler ultra deep is another bare catalogue term; the SKU on the sheet is what separates it from similarly named items elsewhere.
Because these names are not standardised, never map a competitor’s grade name onto a TOP-Q® line. Put each supplier’s own terminology in your comparison and ask which test method sits behind each characterisation term.
4. What a specification sheet covers
| Field | What it tells you |
|---|---|
| HA concentration (mg/ml) | Mass of HA per unit volume |
| Cross-linking information | How the gel network is produced |
| Gel and particle characterisation | How the manufacturer describes the gel |
| Fill volume | Declared volume per syringe |
| Presentation | Pre-filled syringe and included accessories |
| Sterilisation and shelf life | How sterility is assured and dating is handled |
| Lot traceability | How a unit maps back to a production batch |
When comparing sheets from different suppliers, line them up field by field rather than by marketing headline. Ask for the whole pack at once — specification sheet, IFU, labelling artwork and the documents that actually exist — with revision dates, so the files in one folder all belong to the same version.
5. How the lines fit into the wider catalogue
The four facial lines are one part of the TOP-Q® product range. Red Lips is a dedicated lip filler presentation with its own page. Large-volume products are split into two pages — 10 ml / 20 ml and 50 ml — because they are separate products, not one product with a different number on the box.
Beyond hyaluronic acid, the catalogue is also grouped by material class: PLLA, CaHA and polynucleotide (PN) boosters. Our material-class guide covers that second axis. The two axes are independent: the class tells you which document family to open, and the line or presentation tells you which SKU to write on the order.
6. Common points of confusion
- Assuming the names are standard grades. They are TOP-Q® catalogue identifiers, not industry-wide categories.
- Treating a cached PDF or a blog post as the current specification. Always ask for the dated sheet.
- Assuming two labels are equivalent. Match the SKU and the test method, not the adjective.
- Confusing the HA facial lines with material classes. PLLA, CaHA and PN are a different axis of the catalogue.
- Ordering by volume only. Several TOP-Q® lines share the 1 ml format.
7. What we provide, and what we do not
TOP-Q® is an inquiry-based supplier for distributors, professional channels and private-label partners. We provide product specifications, packaging information and supply documentation. We do not provide treatment protocols, indication lists, clinical outcome data, efficacy or duration claims, or medical advice. CE and ISO 13485 documentation issued by domestic certification bodies is available on request; its acceptance depends on the destination market’s rules. If you need the manufacturing background, the About TOP-Q® page describes the company and its product scope.
Frequently asked questions
Are Fine, Derm, Deep and Ultra Deep different materials?
No. They are separate presentations within the TOP-Q® hyaluronic acid dermal filler line, each with its own specification sheet and SKU. Material classes such as PLLA and CaHA are a different axis of the catalogue.
Which TOP-Q® fillers come in 1 ml?
The Fine Line, Derm Line, Deep Line and Ultra Deep facial presentations are listed as 1 ml products; the product range also shows larger-volume and material-class items. Confirm the declared volume on the current sheet before ordering.
Do the line names describe approved indications?
No. They are catalogue identifiers. Any use-related question has to be answered from the current IFU for the relevant market and by a qualified professional.
Where do I find the specification for a line?
On that line’s product page, and in the current dated specification sheet. If a web page and a sheet differ, the dated sheet is the reference.
Is Red Lips part of the same HA filler line?
It is a dedicated presentation in the TOP-Q® range with its own product page, specification sheet and SKU. The large-volume products are likewise separate items.
Do you publish prices or clinical results?
Neither. We do not publish clinical outcome or duration claims.
