BioSignal Facial Serum

Absorbs in seconds. Compounds over months. The daily step of the protocol — botanical peptides carried on Pyrenean mineral water.

Not yet available to purchase.

01 The Two Effects

Two effects. One bottle.

Every Zero Lines formulation does two things at once. The Serum makes the pair unusually easy to feel: one arrives the day you open it, the other is built quietly underneath, for as long as you keep going.

Same day

Immediately

It absorbs in seconds. Before you have finished the rest of your routine the skin looks plumper and reads more luminous — light sits differently on it, and it does so from the very first application.

That is an appearance you can see the same day. Like makeup, except it is skincare.

Week after week

Over time

Daily use is what carries the signal. A botanical peptide complex on a Pyrenean mineral base is formulated to support the barrier and the skin’s own structure — so lines have less to return to.

12 weeks

Eight to twelve, unbroken. That is the horizon daily use is written around — nothing about it is meant to be dramatic in week one.

The first effect is why you will like it tonight. The second is why we ask you not to skip it.

The Skin Analysis

Is a daily signal what your skin is missing?

Sixteen questions, one photograph, and an address to send it to. The analyser reads your skin across eight markers, sets out what appears to be driving them, and names the formulations that follow — the serum among them, or not.

02 Mechanism

Why both things happen.

The same-day change is a surface story, and we would rather say so. The mineral base and the humectants leave the skin holding water more evenly within minutes — and skin that holds water evenly reflects light evenly, so it reads smoother and more luminous. Nothing structural has happened yet.

The slower change is a different mechanism entirely. The botanical peptide complex is shaped to resemble the messenger molecules the skin already uses, and hydrolysed collagen travels with it at a molecular weight chosen for absorption. Together they are formulated to support the fibroblast activity behind the skin’s own structure.

Which is why it is progressive: the tissue does the work, on its own timetable. Daily application simply keeps the instruction arriving.

We are not the repair. We are the instructions.

External use only

Formulated for external application to the face, neck and décolletage. Avoid contact with the eyes. If irritation occurs, discontinue use and consult a healthcare professional.

03 The Formulation

Four things that matter.

A short list, deliberately. Everything in the bottle does one of the two jobs — and the base is not an afterthought, it is half the reason the rest works.

  • Botanical peptide complex

    Derived from watermelon extract and shaped to resemble the messenger molecules the skin already uses.

  • Hydrolysed collagen

    Cut to a molecular weight chosen for absorption rather than for surface film.

  • Pyrenean mineral water

    The base. Zinc, selenium, copper and magnesium in ionic balance — the cofactors the skin’s own antioxidant enzymes need to work.

  • Rose and chamomile flower waters

    The botanical carriers, and the reason it settles quietly: no sting, no heat, almost no scent.

Ingredients, So Far

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 fragrance added for its own sake The rose and chamomile are flower waters doing the carrying, and they are the reason it settles quietly: no sting, no heat, almost no scent. What you smell is the formulation.
  • No drying alcohol, sulphate, paraben or silicone The common irritants, avoided across all six formulations.
  • No retinoid, hydroquinone or salicylic acid None of the six carries any of them. If you use a retinoid of your own, it does not belong in the same application as this.

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.

If you would like to read a label properly in the meantime, the method is in the Journal, and the questions about sensitivity, pregnancy and testing are answered in the FAQ.

04 How to Use It

Ninety seconds, twice a day.

Rhythm matters far more than quantity here. More drops will not speed anything up; a missed fortnight is what actually costs you.

  1. 01

    Cleanse

    Start on clean skin, still barely damp. It travels better into skin that is not bone dry.

  2. 02

    Warm

    Three to four drops into the palm. Press the hands together before they touch your face.

  3. 03

    Press

    Press it in — face, then neck, then décolletage. Never drag. Pressing helps absorption without pulling the skin.

  4. 04

    Layer

    Give it about a minute, then the day cream or the night cream, according to the hour.

Texture

Liquid light. Molecular intention.

Cool for a second, gone in a few more. No film, no tack, nothing left sitting on the surface to catch the light in the wrong way.

That absence is deliberate. A serum you can still feel an hour later is working on your fingertips. This one is built to be somewhere else by then.

05 In the Protocol

The one that compounds.

Steps 01 and 02 are weekly interventions. Step 03 is the one you do every day — the connective tissue of the whole protocol, and the reason the weekly steps have something to build on.

The full protocol All six formulations
06 Not To Be Confused With

Not a stronger step, a daily one.

The Line Corrector is built on the same pair — hydrolysed collagen and a botanical peptide complex — so it is often read as the serum with the volume turned up. It is not: it is a weekly dose placed on a few square centimetres. And the cream that follows a minute later does a different job again.

Formulation When it is used What it is for Immediately Over time
03 · Signal Bio-Signal Face Serum This page Morning and evening, on clean skin, across the whole face before either cream. Keeping the same instruction arriving on the days between the two weekly steps. It absorbs in seconds; skin looks plumper and reads more luminous before the routine is finished. Daily repetition is the whole of it. Nothing here is meant to be visible in week one.
02 · Activate Precision Collagen Renewal Line Corrector One evening a week, within minutes of the peeling gel being rinsed off. A measured dose placed on the few square centimetres where expression has settled. Expression lines look visibly smoother within minutes and hold that look through the day — placed, not spread. Hydrolysed collagen and a botanical peptide complex again, formulated to support the same structure, at a weekly interval rather than a daily one.
04 · Shield Environmental Shield Day Cream Every morning, a minute after the serum, with sun protection on top of it. Holding the serum in place, and taking the environmental load off the skin beneath it. Comfortable and even the moment it is on; two or three minutes later it is a base make-up sits down on. A standing daily barrier, with Pyrenean minerals beneath it as cofactors for the skin’s own antioxidant enzymes.

The serum carries the treatment; the cream protects it and holds it in place. Used together they do what neither does alone. All six compared.

07 Questions

Frequently asked.

What will I notice on the first day?

It absorbs in seconds, and the skin looks plumper and more luminous almost straight away — often before you have finished the rest of your routine. That is a change in appearance, and it is meant to be one.

How long before the lasting effect shows?

Daily use is what carries it. The support accumulates gradually, and eight to twelve weeks of unbroken twice-daily use is the horizon the protocol is written for. Individual results vary.

Morning or evening?

Both — the protocol is written for twice daily. If you can only manage once, choose the evening, so the actives sit alongside the skin’s own overnight renewal.

Can I keep using my other serum?

The BioSignal is designed as the primary active serum inside the protocol. If you want to keep another, use it at a different time of day rather than layering the two.

Do I still need the Line Corrector if I use this?

They do different jobs. The Line Corrector is a weekly, targeted treatment on specific expression lines; the Serum is the daily one, across the whole face and neck. The protocol is designed around both.

Is it suitable for reactive skin?

It is formulated for external use on the face, neck and décolletage and suits most skin types, including oily, combination and dry. If your skin is reactive, or you are treating a diagnosed condition, speak to your doctor or a dermatologist before adding any new active.
