How we calculate this
This refill is a doypack: a pouch uses at least half the plastic of a rigid 250 ml bottle (~25 g). That saves 12,00 g — the bottle itself you buy only once.

Doypack versus bottle. Kenvue reports for Le Petit Marseillais that a pouch refill cuts plastic packaging by 50%. A rigid 250 ml bottle weighs ~25 g; half of that is ~12 g.
Kenvue: 50% less plastic with doypack refills
The bottle itself carries no figure. That bottle is the reusable part. The saving happens on every refill, not when you buy the bottle — which is why the lotion bottle deliberately shows no tile.
Why this matters
Plastic does not disappear. It breaks into ever smaller pieces and stays in our soil, rivers and sea for centuries. Every piece of packaging that is never made is the only plastic guaranteed never to wash up anywhere.
Concretely: you buy the case once and refill it after that. With an ordinary deodorant you throw the whole pack away every time. The plastic you never buy never has to be made, shipped or burned either.
This comparison is only here to make the number tangible. It is an illustration, not hard science.
By choosing an IMPACT product you avoid all of this. That does society, today and tomorrow, an enormous service and makes a big positive difference to the future of us all.
