If you tend to sweat a lot, you may wish to apply deodorant or antiperspirant more often. Since deodorant doesn't absorb into your body, there is no limit to how often you can use it to mask odor or to provide a pleasant scent.

Deodorant masks odor, while an antiperspirant reduces how much you sweat. Both products work wherever they are applied to your body, most commonly on the underarms. Many times, deodorant and antiperspirant are combined in a single product. Deodorants offer two forms of protection against odor.

If you love the simplicity of a solid but don't want the formula to stain your skin or clothes, choose an invisible solid deodorant. This type of deodorant has a similar consistency to a standard solid, but it goes on clear instead of white.

Deodorant is a substance that covers up the smell of sweat. You might use deodorant in the summer, applying it under your arms every morning. Deodorant is used to mask the smell of body odors or perspiration, either by keeping you from sweating or by killing the bacteria that can grow in sweaty areas of the body.

Clinical strength deodorants (which are technically antiperspirants) work because they contain higher levels of the aluminum-based, active ingredients that are found in traditional formulas. These form a plug that blocks the sweat duct to prevent sweat from escaping.

But is wearing antiperspirant deodorant on your skin all day and all night harmful? Lipner says “there are no known health risks associated with wearing deodorant at night or wearing deodorant too often.”

Using expired deodorant or antiperspirants won't likely harm your health. However, the formula or fragrance of the product may deteriorate so, if you've opened or used your deo, you should replace it every six to 12 months for best results (closed deodorants can last for more than a year).

In general, deodorants and antiperspirants are safe products for most people in good health to use. However, if you have an allergy or other health condition that could be affected by the ingredients in deodorant, it's best to discuss this with your doctor. Do you have questions about deodorant's impact on your health?

What is deodorant? Deodorant is a skincare product that helps to keep your underarms smelling fresh. Rather than stopping sweat like antiperspirant, deodorant works on the bacteria on the skin to stop the odour escaping from your pits. When we perspire, these bacteria digest the fats and proteins in our sweat.

While using expired deodorant won't necessarily harm your health, it's best to replace it every 12 months for optimal results. Closed deodorants can last for more than one year, but if you can't remember when you bought it or if it has been more than a year, it's best to toss it.
