Antiperspirants are one of the most effective and widely used treatments for excessive sweating (hyperhidrosis). Unlike deodorants, which help control odor, antiperspirants work by reducing the amount of sweat produced. Understanding how they work can help you use them more effectively and choose the right option for your needs.
This is Part 1 of our antiperspirant series. Continue with Part 2: Strengths and Aluminum Salts and Part 3: Deodorants and Fragrances.
Quick Summary
- Antiperspirants reduce sweating by blocking sweat ducts using aluminum salts.
- They can be used on many areas of the body, not just the underarms.
- They are considered a first-line treatment for hyperhidrosis.
- They are different from deodorants, which only control odor.
- Choosing the right formulation and strength can improve results and reduce irritation.
What Is an Antiperspirant?
An antiperspirant is a topical product that contains aluminum salts and is designed to reduce sweating. It is considered a first-line treatment for many people with hyperhidrosis because it directly targets sweat production.
Although commonly used under the arms, antiperspirants can be applied to many areas of the body, including the hands, feet, face, and other regions where excessive sweating occurs.
For people with more persistent or severe sweating, prescription-strength antiperspirants may provide more effective control than over-the-counter options.
How Do Antiperspirants Work?
Antiperspirants work by blocking the sweat ducts. When aluminum salts are applied to the skin, they dissolve in moisture and form temporary plugs within the sweat glands. These plugs reduce the amount of sweat that reaches the surface of the skin.
This is a localized effect, meaning it only works in the area where the product is applied.
Where Can You Use Antiperspirants?
Antiperspirants are not limited to the underarms. Depending on the formulation, they may be used on:
- Underarms
- Hands
- Feet
- Face and scalp (with appropriate formulations)
- Groin or under the breasts (with gentle formulations)
Using the right formulation for the right body area can help improve results and reduce the risk of irritation.
Antiperspirants vs Deodorants
It is important to understand the difference between antiperspirants and deodorants:
- Antiperspirants: Reduce sweating by blocking sweat ducts
- Deodorants: Help control odor but do not stop sweating
If your main concern is excessive sweating, antiperspirants are typically the more effective option.
Choosing the Right Antiperspirant
There are multiple types of aluminum salts used in antiperspirants, and they vary in strength and effectiveness. There are also different formulations (such as creams, lotions, gels, and serums) designed for different areas of the body.
In Part 2 of this series, we break down the differences between strengths and aluminum salts to help you choose the right option.

When Are Antiperspirants Not Enough?
While antiperspirants are effective for many people, some individuals may need additional treatment. If sweating is not controlled with topical products alone, other options may include:
