Antiperspirants
Antiperspirants are different to deodorants which just mask body odour but don’t actually reduce sweating and these over-the-counter or prescription topical products are often the first line of defence in combatting excessive sweating.
Antiperspirants containing aluminium chloride work as an astringent and aim to decrease sweat secretion, but they can often cause skin irritation and are often only effective for milder cases of hyperhidrosis.
