Nobody dies from
bad smell.
That's precisely
the problem.
These problems do not appear in any health statistic or government report. But they end careers. They dissolve relationships. They keep millions of people physically smaller in the world: covering their mouth when they laugh, turning down the job, ending the relationship before it starts.
liche is a postbiotic personal care platform. We restore the ecosystems a century of suppression-based hygiene was designed to kill.
We start with oral care.
For investors and strategic partners. Hind reviews every note personally.

Chapter one, the invisible confidence crisis
The last person
to know is
always you.
There are conversations people stop having. Jobs they don't apply for. Relationships that end quietly, without explanation. A category of suffering so ordinary, so below the clinical emergency threshold, that no one built a serious solution for it.
Body malodour is not a hygiene problem. It is a product logic problem. A century of suppression-based chemistry that kills indiscriminately and leaves the root cause untouched.

You weren't given bad hygiene.
You were given the wrong tools.
The liche approach
Restoration,
not suppression.
A century of self care has been built on a single instruction: kill bacteria broadly, mask what remains. liche is built on the opposite instruction. We restore the body microbiome rather than fight it, so your body begins doing what it was designed to do on its own.
liche will do so by creating our own postbiotic ferments.

The platform
Oral care is where we start.
The rest of the body follows.
Every zone liche works in exists for the same reason. Microbial imbalance causing silent, underaddressed suffering. Too quiet to count, too common to ignore. Each zone gets its own system. Each system restores rather than suppresses.
