eli5 How does activated charcoal underarm antiperspirant work?


I’m actually just wondering if it can enter your blood and if no how come? I’m planning on buying some antiperspirant with it and I’d like to understand how it works exactly.

Activated charcoal is good at absorbing and binding to things, so it’ll absorb sweat, like, and bacteria that produce B.O.

No, it cannot enter your blood through your skin. You skin is like the plastic of a water balloon, it keeps your blood in, and keeps other stuff out, and the charcoal molecules are too large to pass through the skin cells.
