Antiperspirants vs. Deodorants:

Antiperspirants and deodorants work in different ways to reduce body odor. Antiperspirants work by reducing sweat. Deodorants work by increasing the skin’s acidity.

• Antiperspirants temporarily block sweat pores. Blocking sweat pores reduces the amount of perspiration that reaches your skin.
• Deodorants are formulated to eliminate armpit odor but not perspiration. They’re typically alcohol-based. When applied, they turn your skin acidic, which makes it less attractive to bacteria. Deodorants also commonly contain perfume to mask odor
