Attraction
The positively-charged polymer is drawn to the negatively-charged bacteria surface and binds to its membrane.
THE SCIENCE
Fast. Effective. Gentle.
A resistance-free, membrane disruption technology invented at A*STAR — here’s how it works, why it keeps protecting, and how it stays gentle on skin, body and the environment.

Smart Ionic Shield™
Destroys harmful bacteria in seconds — while staying gentle enough for daily skin.
A next-generation antibacterial platform, exclusively licensed from A*STAR Singapore — forming a long-lasting protective layer while keeping skin nourished and healthy.

MechanismMembrane disruption
HOW IT WORKS
Three stages to safer skin.
A physical, membrane disruption mechanism — not a chemical one that resistance can adapt to.
Disruption
It physically ruptures the membrane — a mechanical kill that bacteria can’t readily evolve around.
Elimination
Bacteria are neutralised on the surface, breaking the cycle of recurring infection — for up to 48 hours.
Performance
Fast, lasting, broad-spectrum.
One physical mechanism, three advantages you can rely on every day.
Broad-spectrum
Active against Gram-positive and Gram-negative bacteria.
Fast-acting
Eliminates 99.9% of targeted bacteria within 30 seconds of contact.
Long-lasting
A stay-on layer keeps defending for up to 48 hours after one application.
Safety by design
Safe on skin, body and the environment.
The same properties that make it effective are what make it gentle.
Skin safety
A large macromolecule that stays on the surface — no systemic exposure, gentle enough for fragile skin.
High selectivity
Highly selective toward bacterial membranes, leaving healthy human cells untouched.
Environmental care
Stable in storage, yet biodegradable by environmental enzymes once its job is done.

Resistance science
Built to fight resistance, not fuel it.
Antimicrobial resistance occurs when microbes stop responding to treatment — making infections harder to cure and raising the risk of serious illness.
— World Health Organization
Chemical actives
Small-molecule antiseptics & antibiotics
Work by inhibiting biochemical pathways — repeated use lets microbes adapt, driving resistance over time.
Trisafe mechanism
Physical, membrane disruption action
Ruptures the bacterial membrane directly — a mechanical kill that’s hard to evolve around.
What makes Trisafe different
We turn antimicrobial science into everyday protection.
Every product is powered by the same breakthrough — the A*STAR-licensed Smart Ionic Shield™. It’s tough on bacteria, yet gentle on your skin, your cells and the environment. Here’s why it protects differently:
Broad Spectrum
Effective against bacteria.
High Selectivity
Highly selective towards bacteria — not healthy human cells.
Fast Acting
Eliminates 99.9% of bacteria within 30 seconds.
Long Lasting
Continual protection for up to 48 hours after application.
Anti-Drug Resistance
A unique membrane disruption mechanism prevents the development of resistance.
Safe on Skin
A large macromolecule that does not penetrate skin — no systemic side effects or irritation.
Safe on Environment
Stable under storage conditions, yet biodegradable by environmental enzymes.
Prevention, made possible
Be proactive about skin protection
Clinically validated, resistance-free, and gentle enough for daily use.
