Apply at night before going to bed to allow to dry fully. Leave on overnight and wash off any residue in the morning with soap and water.
Antiperspirants generally contain aluminium chloride.
Aluminium particles are taken up by cells in the sweat glands, causing them to swell and close up so they no longer release sweat.

Apply 2 strokes up and 2 strokes down to each armpit (for stick type). You should only need to do this once or twice a week for good quality antiperspirants.

My 2 cents:
There are concerns that aluminium particles may cause Alzheimer's Disease or cancer as more aluminium are found in the brains of Alzheimer's Disease patients and more women are having breast cancer.
Researches done did not confirm the above concerns but that does not mean there is no link. Heavy metals are present in food, in the air and man make products. So even if one does not use products containing heavy metals, one may still have cancer or Alzheimer's Disease. But using more man make products like antiperspirant will increase the sources and more heavy metals to be introduced into our bodies.
