If you’ve ever stood in the bathroom aisle wondering which product to grab, you’re not alone. Everyone wants to feel confident at school, sports, or social events, and choosing the right product can help.
If sweat is your biggest worry, go for antiperspirant. If odor is the main issue, deodorant works fine. Many use a combo product for all-day confidence.
Antiperspirants and deodorants are often confused, but they’re not the same. Antiperspirants stop sweat by blocking sweat glands with aluminum compounds, while deodorants fight odor by reducing bacteria and adding fragrance. Antiperspirants are regulated as drugs by the FDA, while deodorants are considered cosmetics.
Best time to apply antiperspirant is at night, when sweating is minimal, so it can “plug” sweat glands more effectively. Deodorant in the morning is great for masking odor during the day. Many sticks or sprays include both deodorant and antiperspirant, giving double protection.
The Basics
- Deodorant:
- Purpose: Masks or neutralizes odor.
- How it works: Makes your skin more acidic, which bacteria don’t like, and often adds fragrance to cover smells.
- Regulation: Considered a cosmetic by the FDA, meaning it’s designed to cleanse or beautify, not change how your body works.
- Antiperspirant:
- Purpose: Reduces sweat.
- How it works: Uses aluminum salts to temporarily block sweat glands, so less moisture reaches your skin.
- Regulation: Classified as an over-the-counter drug by the FDA, since it affects body function.
