Antiperspirant is a skincare product that helps reduce underarm sweating. This is not to be confused with deodorant, which is only there to combat the bad odour.
Antiperspirants work by blocking the pores on the outer layer of your skin, reducing the amount of sweat allowed to the surface.
What roles does aluminium play in all of this?
Aluminium salts are included in antiperspirants to help reduce the sweat flow in the underarm area. The salts restrict access to the upper part of the sweat glands so that it is more difficult for sweat to be released.
The aluminium salts also play a part in minimising the smell associated with sweat, by reducing the number of bacteria linked to odour production.
