Sweat Guide

Everything you need to know about sweat, odor, and how to stay fresh all day long. This guide covers the basics, the science, and the best solutions for every situation.

Understanding Sweat

Sweat itself is odorless. The smell comes from bacteria on your skin breaking down the proteins in sweat. Understanding this is the first step to managing it effectively.

Antiperspirant vs. Deodorant — What's the Difference?

• Antiperspirant — reduces sweating by temporarily blocking sweat glands. Best for people who sweat excessively.
• Deodorant — masks or neutralizes odor but does not stop sweating.
• No Sweat USA recommendation — if you sweat heavily, choose an antiperspirant. If odor is your main concern, a deodorant may be enough.

When to Apply Antiperspirant

1. Apply at night — sweat glands are least active while you sleep, allowing the active ingredients to work more effectively.
2. Apply to dry skin — moisture reduces effectiveness.
3. Don't apply right after showering — wait until skin is completely dry.
4. Consistency matters — use regularly for best long-term results.
