Introducing Bio-Clear: Poly Acid Daily Wash

Use Bio-Clear in place of your soap or body wash. It cleans the surface, clears the pores and follicles, and breaks up the build-up and biofilm where bacteria shelter. It keeps the skin at a slightly acidic pH, turns the compounds behind fishy and ammonia-like odours into a heavier, water-loving form that is easy to rinse off. It also washes away the skin’s stale, waxy oxidised sebum and neutralises the compounds it forms.

Why choose Bio-Clear over soap or body wash?

Soap is alkaline. With every wash it lifts away the skin’s natural acidity, which the skin then has to rebuild. That acidity earns its keep: it holds the barrier together, keeps everyday bacteria in check, and keeps odour compounds in their heavy, non-airborne form. Bio-Clear cleans at that same acidity and hands the skin back its acid balance.

Acid odours (sour, cheesy) and amine odours (fishy, ammonia) behave in opposite ways with pH. Raise the pH, and the sour notes turn into heavy salts that cannot lift off the skin, while the amine notes shift into their airborne form and grow sharper. Lower the pH, and the pattern reverses: the amines lock into salts of their own, and the sour notes lift more freely.

Soap is high pH. It silences the sour notes for the minute it is on the skin, frees the amine notes into the air, and strips the skin’s own acid mantle in the process. The surface then has to rebuild for hours before it is protective again.

No single pH silences both by chemistry alone. So Bio-Clear traps one side with pH and prevents the other at its source. It sits below pH 5, close to the skin’s own. At that pH the amines are locked as heavy salts, the acid mantle is kept intact, and the biofilm that shelters the bacteria is taken apart at the same time. The sour, cheesy side is handled in a different way, by lowering the bacteria that make it. One formula meets the whole odour map.

Bio-Clear must be followed up with targeted treatments such as BVIC, BVIC Endurance, and BVI Barrier Cream for better odour control.

Any odour that is metabolic in nature has to be managed through a two-pronged approach: diagnosis and internal care led by a doctor, and surface control through Bio-Clear and the rest of the Volatile Control System. Both are essential for successful odour control.

How it works

Bio-Clear is a rinse-off body wash used daily, held on the skin for about two minutes, then rinsed clean. It is the first step of the Volatile Control System. Its job is to prepare the skin surface: to trap the odour molecules the day has already made, to clear the biofilm and follicular contents that keep making them, and to leave a clean, acid-balanced surface for the targeted treatments that follow. It does this through four linked actions, each described below.

It traps the odour molecules at the surface by pH

The wash sits at a low pH, close to healthy skin’s own acid pH. That low pH does most of the heavy lifting on amine odour. Fishy trimethylamine and sharp ammonia are only airborne in their neutral form; below pH 5 they convert almost completely into their salt form, which is heavy, water-soluble, and cannot lift off the skin. A normal body wash or soap sits above pH 7, which frees those amines and pushes them into the air. Bio-Clear traps them, then rinses them away with the lather.

It destroys the biofilm that shelters bacteria

The bacteria that make body odour do not sit as loose cells on clean skin; they build a sticky matrix, held together by calcium bridges and protein, that shelters them from soap and from the skin’s own defences. Bio-Clear takes this matrix apart from five directions at once: chelating agents strip out the calcium that holds the bridges together, a biosurfactant loosens the matrix and lifts it off the skin, an acid lowers the bacteria building it, an anti-adhesion agent stops fresh bacteria re-attaching, and the cleansing base and the rinse carry the loosened matrix away.

It clears the follicle

In the hair follicle, sebum, dead skin cells and the steroid molecules behind the musky, animal note all collect. The bacteria living there break this material down into odour, and the warm, closed space lets it build. Bio-Clear clears the follicle with three kinds of acid. Two are water-loving molecules that work at the surface: one loosens the bonds between dead skin cells so the day’s build-up rinses off without scouring, and the other draws in water to keep the skin soft. The third is a lipid-loving molecule. It dissolves into the sebum and follows it down the follicle, loosening the trapped contents so they rinse away before the bacteria can work on them.

It neutralises the odours and mutes the sulfur note

The sharp onion or garlic note comes from a few specific bacteria on the skin. Bio-Clear lowers just those and spares the skin’s healthy flora, so less of the smell is made in the first place. The waxy, musty note comes from 2-nonenal, a molecule that forms when sebum oxidises, and it is bound and converted into a heavy form that is easy to rinse away. Any loose sulfur groups left on the skin are trapped and muted further.

How to use

When: Every day, in the shower or bath. Twice a day is fine for most skin types but keep contact time low during the second shower.

Where: All over the body, like any body wash. For external use only; keep it off the face and out of the eyes.

1. Wet your body. Step under the water and wet your body. If you use a loofah or flannel, wet that too. A loofah is optional: it helps build an even lather, but your hands are good too.

2. Load your hands or loofah. Squeeze one to two pumps of Bio-Clear onto damp hands or a damp loofah. One pump suits a small area, two for a full-body wash.

3. Work up the lather. Rub your palms together with a little water, or scrunch the loofah a few times, until it builds a thick, creamy foam.

4. Take the lather onto your body. Sweep it over your skin in gentle circles, moving from one area to the next, until every part you are washing is covered. Add a splash of water if you need more glide.

5. Leave it on for up to two minutes. This short wait lets the actives work on odour. Carry on with the rest of your shower while you wait. A mild tingle in the first 30 to 60 seconds is normal and settles on its own.

6. Rinse it all off. Rinse thoroughly with water until the skin feels clean and there is no slippery film left.

7. Pat dry. Gently pat the skin dry. Moisturise with BVI Barrier Cream and use targeted treatments such as BVIC or BVIC Endurance.

If you use a loofah, look after it. Rinse it well after every wash, squeeze it out, and hang it somewhere airy to dry fully between showers. Replace it regularly. A damp, dirty loofah grows the same odour-causing bacteria this wash removes, so keeping it clean matters.

Sensitive, very dry, or eczema-prone skin: go gentle. Use your hands or a soft cloth rather than a loofah, and use Bio-Clear once a day. If you shower a second time, rinse with plain water and skip the wash that time. This keeps the skin’s natural balance and avoids over-drying.

Safety: For external use only. Keep out of the eyes; if any gets in, rinse straight away with plenty of water. Not for the face. Do not use on broken, cut, inflamed, or irritated skin; wait until it has healed, since an acid wash will sting on skin that is not intact. Freshly shaved skin may tingle a little more than usual, which is normal.

Common questions

Is Bio-Clear a soap, a body wash, or a treatment?

It is a rinse-off body wash you can use every day. What makes it different from a normal body wash is what it is designed to do: trap the amine odours by pH, clear the biofilm and follicles the bacteria hide in, and leave a clean, acid-balanced skin.

How is it different from my normal body wash?

A normal body wash sits above pH 7 and cleans surface dirt. It silences the sour odour notes for a minute, but it frees the fishy and ammonia notes into the air, and it strips the skin’s own acid mantle. Bio-Clear sits below pH 5, so it traps the amines and preserves the acid mantle, and it takes the biofilm apart at the same time.

Why is it acidic, and is that safe?

The acid level sits within recognised safety limits for cosmetic washes, and it is only on the skin for about two minutes before you rinse. It keeps the skin’s own acid mantle intact, making it a good fit for sensitive and reactive skin. A mild tingle in the first minute is normal and it fades. Burning or lasting redness is not; stop use if that happens.

What is biofilm, and why does it matter for body odour?

Body-odour bacteria do not sit on the skin as loose cells. They build a sticky matrix, held together by calcium bridges and protein, that shelters them from soap. That is why odour can return so soon after a shower. Bio-Clear takes the matrix apart from several directions at once: it strips out the calcium that holds the bridges together, loosens and lifts the matrix off the skin, lowers the bacteria building it, and makes it harder for new bacteria to take hold again.

Does it really help with fishy and ammonia odour?

On the skin, yes. Below pH 5, the fishy and ammonia molecules are trapped as heavy salts that cannot lift off, and the rinse takes them away. If a strong fishy or ammonia odour covers the whole body, the source may be inside the body, and that needs a doctor alongside surface control.

Will it exfoliate my skin?

Yes, gently. It contains three acids for this purpose.

How often should I use it?

Every day, in place of a normal body wash. Twice a week, use Bio-Reset: Poly Acid Resurfacing Wash instead, for a deeper pass on the same surface.

How long do I leave it on?

About two minutes. Work it into a dense lather, leave the lather on the skin, then rinse. Give it the full two minutes to do its job.

Can I use it on my face?

Bio-Clear is designed for the body. Facial skin is thinner and needs a wash tuned for the face; do not use it above the neck.

Can I use it on freshly shaved skin?

It may tingle on freshly shaved skin, and on the day of shaving that tingle can be strong. Wait a day if shaving triggers sensitivity. Never use on nicks or broken skin.

Do I still need the rest of the system?

Bio-Clear prepares the surface. For persistent odours, pair it with BVIC or BVIC Endurance depending on the nature of your odour. For whole-body odour control and lipid barrier support after the shower, pair it with the BVI Barrier Cream. Use Bio-Reset: Poly Acid Resurfacing Wash twice a week in place of Bio-Clear to maintain the benefits.

Is it safe for sensitive and reactive skin?

It is made for sensitive and reactive skin. Do not apply to irritated, inflamed, or broken skin. If irritation occurs, stop use immediately. For external use only.

Can I use it while pregnant or breastfeeding?

If you are pregnant or breastfeeding, consult your doctor before use.

Does it have a scent?

It is fragrance-free. It carries only the mild, neutral smell of its own ingredients.

What sizes does it come in?

A 250ml full size, and a 100ml discovery size.
