Precision Collagen Activation Refill.
The cartridge that keeps the Line Corrector running. The same formulation, the same visible smoothing from the first application — and twelve months of it, because you already own the applicator.

Two things at once. Always.
Every Zero Lines formulation works on two timescales at once. The Refill is how you keep both running.
Immediately.
Within minutes of the first applicationPlaced along an expression line, the surface phase begins at once: the line looks visibly softer within minutes, and is designed to hold that appearance through the day. Nothing here differs from the Line Corrector — identical formulation, identical behaviour, first cartridge to last.
Like makeup, except it is skincare.
Over time.
Built by repetition, week after weekUnderneath, hydrolysed collagen and botanical signal peptides are formulated to support the skin's own structure, so lines have less to return to. That half is slow and cumulative by design — which is exactly why it needs continuity, and why the cartridge is sized in months.
The slow half is built on hydrolysed collagen — examined at length in the Journal — and it is the half that asks for continuity.
Is the immediate effect enough for you?
Some people want only the smoother look on the day; others want the structure underneath supported as well. Sixteen questions, one photograph and an address to send it to, and the analyser returns a written assessment across eight markers — and the honest answer for your skin.
Your photograph is not kept
Not another product. The same one, continued.
The Refill is a cartridge. What it does not carry is the applicator — the engineered part, the precision tip that places a measured dose on a few square centimetres rather than a whole face. That is designed to be kept; the Refill is what goes into it next.
Which is the honest reason it exists. Some people will only ever want the immediate effect — the line that looks softer by the evening, the face that photographs better that day. That is a perfectly legitimate way to use this range, and the Refill is how you do it indefinitely: the applicator is bought once, and after that you replace only what has been used.
The applicator is the instrument. The cartridge is the treatment.
Engineered exclusively for the Zero Lines precision applicator; it cannot be used on its own. If you are starting the protocol, begin with the Line Corrector.
Four ingredients, two timescales.
Two are why you see something today. Two are why there is a reason to keep going.
-
01
Hydrolysed collagen
Cut small enough to be read as a signal rather than sit on the surface as a film. The slow, structural half.
-
02
Botanical signal peptides
Carried on rose and chamomile flower waters. The half that is designed to be visible the same day.
-
03
Botanical extract complex
Witch hazel, calendula, chamomile, horse chestnut, peppermint, yarrow, mallow, linden and St John's Wort — working on the look of tone and fluid balance.
-
04
Pyrenean mineral water
The base. Zinc, selenium, copper and magnesium in ionic balance — cofactors the skin's own antioxidant enzymes need to function.
The list we cannot publish yet.
Four named actives and a reason for each is what we have. A complete ingredient list is what you are entitled to, and it does not exist yet. Both of those are true, so both are printed here.
What it deliberately does not contain
- No applicator The one thing this cartridge deliberately leaves out. The precision tip is engineered to be kept; only what has been used is replaced.
- No needle, and nothing to inject The instrument borrows a clinical shape for accuracy alone. What arrives at the tip is a cream.
- No retinoid, hydroquinone or salicylic acid None of the six carries any of them, and none carries artificial fragrance, drying alcohol, sulphate, paraben or silicone.
What is not published yet
- The complete list, in INCI order The formulation is not final. A list published before it is would be a work of fiction we would only have to correct.
- Everything the order would tell you Where each of the four sits, where the 1% line falls, and what the preservative system is. Those are the parts worth reading, and we do not have them to give you.
- When it arrives On the carton and on this site, when the formulations are final and the collection goes on sale. Not before.
The cartridge and the Line Corrector carry the same formulation, so this list is the same list. Sensitivity, pregnancy and testing are answered in the FAQ.
Change it. Then carry on exactly as before.
-
01
Change the cartridge
Twist the spent cartridge off the base, seat the Refill, twist until it locks. One turn of the base primes the tip. Under a minute, no tools.
-
02
Weekly, as before
Once a week, on clean dry skin, placed directly on the lines you are working on. Pat gently; do not rub.
-
03
Or before an occasion
Thirty to sixty minutes ahead, when what you want is the immediate effect to carry the evening.
For external facial application; no injection is required or intended. Avoid the eyes, broken skin and mucous membranes, and keep out of reach of children. If irritation occurs, discontinue use.
The ritual continues.
A spring does not begin again each morning; it simply keeps running, and that is the whole of its usefulness. The Refill lets the protocol behave the same way — the applicator stays where you left it, the formulation is replaced, and between one cartridge and the next nothing about the ritual changes.
Where the water beginsStep 06 is step 02, continued.
Six formulations in a fixed order. The Refill is not a seventh — it is what keeps the second one from ever stopping.
- 01 Renew Bio-Renewal Peeling Gel
- 02 Activate Precision Collagen Renewal Line Corrector — required
- 03 Signal Bio-Signal Face Serum
- 04 Shield Environmental Shield Day Cream
- 05 Restore Renewal and Repair Night Cream
-
06 Sustain Precision Collagen Renewal Refill — you are here
Refill or Line Corrector?
The formulation is the same in both, which is why describing either one never separates them. What separates them is the applicator: step 02 is the instrument with its first cartridge in it, and this is a cartridge on its own.
| Formulation | When it is used | What it is for | Immediately | Over time |
|---|---|---|---|---|
| 06 · Sustain Precision Collagen Renewal Refill This page | Fitted when the cartridge in your applicator is spent — roughly once every twelve months. The weekly step itself does not change. | Continuity. A replacement cartridge, and nothing else: it cannot be used without the applicator. | Identical to step 02 — lines look visibly smoother within minutes, first cartridge to last. | Identical again, and the entire reason it exists: the slow half is worth nothing if the protocol stops. |
| 02 · Activate Precision Collagen Renewal Line Corrector | One evening a week, within minutes of the peeling gel being rinsed off. | Where the protocol starts. The precision applicator, with its first cartridge already in it. | Expression lines look visibly smoother within minutes and hold that look through the day. | Hydrolysed collagen and botanical signal peptides are formulated to support the skin’s own structure, so lines have less to return to. |
If you have not started the protocol, this is not the page you want. Begin at step 02; the applicator arrives once and is kept, and this is what goes into it a year later. All six compared.
Six worth asking.
Can I use the Refill on its own?
No. The Refill is a cartridge, not a complete product; it requires the Precision Collagen Renewal Line Corrector applicator to work. The Line Corrector is bought once, the Refill afterwards.
Is the formulation identical to the Line Corrector's?
Yes. The same hydrolysed collagen, botanical signal peptides and botanical extract complex, on the same Pyrenean mineral water base. Nothing is diluted or simplified — only the packaging differs.
What if I only want the immediate effect?
A perfectly legitimate way to use the range — and the Refill is the affordable way to keep doing it. Because the applicator is reused rather than replaced, continuing indefinitely costs a fraction of starting again.
How long does one cartridge last?
Approximately sixty applications. At the once-weekly rhythm that is roughly twelve months; if you also apply it before occasions, sooner.
How do I change the cartridge?
Twist the spent cartridge off the base, seat the new one and twist until it locks, then turn the base once to prime the tip. Under a minute, no tools.
When can I buy it?
Zero Lines is in pre-launch and nothing in the range is available to purchase yet. The Refill arrives alongside the Line Corrector. Join the waitlist and we will write before ordering opens — or ask us on WhatsApp.

The decline is gradual, so the answer is continuity — the case for a step that never stops.
