mumsnet swears by - my recommendations - driclor and dermalogica

[SarfEasticated]

Driclor antiperspirant - stings like buggery but one application completely stops you sweating for 3-4 days.

Dermalogica daily microfoliant - has the texture of talc but once mixed with water and rubbed into face becomes the gentlest exfoliator ever. Leaves skin soft and bright but not irritated. Lasts for years too.

I went to buy some driclor because I kept seeing it on here, but they didn't have it in Superdrug. I got perspirex instead and that works amazingly well and doesn't sting.
