Deodorants eliminate odour-causing bacteria that thrive in hot and moist spots such as the underarm. Antiperspirants are powerful astringents that reduce the release of perspiration. These two products have different functions, and are commonly mistaken as the same.
Choose the product you prefer. A roll-on or spray contains alcohol and scented oils that may leave a sticky or wet feeling. The stick is easiest to use, and some even consider it more environmentally friendly because it comes without aerosols. To avoid staining your clothes, go for formulations that are not coloured. For the results you want, select a product that indicates deodorising and antiperspirant effects.
