Odour control is not fragrance

Most deodorant is a fragrance strategy. Something is applied that smells stronger than what it covers, and for a few hours the stronger smell wins.

Body odour is close to odourless at the source. Fresh sweat has almost no smell; what you notice is the by-product of skin flora breaking it down over hours. That process is what 01 is aimed at, rather than the result.

How 01 is built

A slim roll-on, applied to clean dry skin. Geranium and rosemary give the scent its character and are refined rather than floral. Jojoba and hyaluron keep skin comfortable enough for daily use without tightness. Colloidal silver sits in the formula as a mineral component.

What we do not claim

It is not an antiperspirant. It does not reduce how much you sweat, and calling it one would mean a different formulation and different regulatory support. We put no hour count on it either — that number needs evidence behind it, and we would rather you formed your own view over a week of use.

An invisible finish, no white residue, and a scent that behaves like a skincare product rather than a body spray. That is the whole brief.
