Multi-pathway odour control
built on peer-reviewed research
Choose the formula based on your odour.
Body odour originates from several distinct biochemical pathways. Each formula below targets a specific set of pathways; select the treatment optimized for your biological odour profile.
Wash · Every day
Bio-Clear
Poly Acid Daily Wash · 250ml full size & 100ml discovery
A daily wash for intercepting multiple biochemical odour pathways in the shower.
Wash · Twice a week
Bio-Reset
Poly Acid Resurfacing Wash · 100ml full size & 30ml discovery
When used twice a week, it maintains the benefits of the daily wash long-term.
Whole body
BVI Barrier Cream
Odour control + barrier support · 500ml full size & 100ml discovery
A post-shower moisturizing cream for multi-pathway odour control and lipid barrier support. For persistent apocrine odour, integrate with targeted spot treatments, specifically BVIC or BVIC Endurance.
Target · Everyday odour
BVIC
Bio-Volatile Inhibitor Concentrate · 50g full size & 15g discovery
An anhydrous concentrate for controlling surface-level microbial odour targeting three distinct pathways at apocrine sites.
Target · Complex odour
BVIC Endurance
Bio-Volatile Inhibitor Concentrate: Endurance · 50g full size & 15g discovery
An anhydrous spot treatment stick for controlling 8 biochemical odour pathways at apocrine sites.
For persistent odours
Complex odours exhibit distinct chemical signatures.
Multiple volatile compounds can frequently manifest concurrently, driven by independent biochemical pathways requiring a dedicated, targeted intervention.
i
The 2-nonenal note
With age, skin surface lipids undergo oxidation to form 2-nonenal, a greasy, waxy compound. Because this process is driven entirely by lipid peroxidation rather than bacterial activity, deodorants fail to control it.

Volatile amines
Ammonia and fishy notes are volatile amines. Mitigation requires an acidic pH system to chemically trap these specific volatiles. Sudden or systemic onset may indicate an underlying metabolic condition requiring clinical evaluation and treatment by a doctor, while concurrent topical intervention manages the volatile compounds escaping through the skin.

Concurrent pathway activation
Hormone fluctuations can trigger the simultaneous manifestation of distinct odour profiles. Shifts in systemic hormone levels alter both sebum composition and the skin microbiome. This causes independent volatile pathways, such as short-chain fatty acids, 2-nonenal, and modified steroidal musks, to activate simultaneously. While common during perimenopausal and menopausal transitions, this multi-pathway convergence can occur during any hormonal shift, regardless of age.
