How Deodorants and Antiperspirants Work
Antiperspirants reduce sweat by temporarily blocking pores with aluminum salts. Deodorants target odor by lowering skin pH or using antimicrobial agents. Many products combine both functions for all-day protection.
Key Ingredients for Odor Control
Aluminum-based compounds such as aluminum chlorohydrate and aluminum zirconium are common active ingredients in antiperspirants. Fragrance, triclosan, and baking soda variants also help mask or neutralize odor. The American Academy of Dermatology notes that these ingredients are generally safe for most users when used as directed.
How to Choose the Best Product
Select an antiperspirant strength based on your sweat level, and choose fragrance-free options if you have sensitive skin. Apply to clean, dry underarms for best results. For persistent odor, consult a dermatologist to rule out underlying conditions.
