If You Only Apply Deodorant in the Morning, It May Not Be Working as Well as It Should squib
Many of us put on deodorant after taking a shower in the morning, and while that may seem like the best way to start the day off fresh, antiperspirants are actually most effective when they're applied in the evening, Joshua Zeichner, MD, director of cosmetic and clinical research at the department of dermatology at Mount Sinai Hospital in New York City, told POPSUGAR.
Antiperspirant is often combined with deodorant and sold commercially, because while deodorant neutralizes odor, it's antiperspirant that prevents sweating. "Antiperspirants contain zinc salts that form a plug within your sweat glands, preventing sweat from reaching the surface of the skin," Dr. Zeichner explained. "At night, sweat levels tend to be lower than in the morning. This allows the antiperspirant to form a more effective plug in the sweat glands," ultimately keeping you drier longer.
