Deodorant vs an Antiperspirant - which one to use ?

1. Both these are entirely different – an Antiperspirant reduces sweat whereas a deodorant minimises odour.
2. These must not be used together. An antiperspirant should preferably be applied at night, giving it enough time to act. Aluminium hydroxide in the antiperspirant, helps block the sweat glands & reduces sweat.
3. Deodorant should preferably be applied after shower. It reduces the odour caused by bacterial action of the sweat.
4. A roll-on is broadly better than an aerosol. It gives an even distribution with limited amount of product. Aerosols may also cause burns.
