What is a deodorant and how does it work?
A deodorant is a cosmetic product applied mainly to the underarms to reduce body odor caused by perspiration and bacterial proliferation. It works by masking odor with fragrances and using antibacterial agents to reduce the bacteria responsible for breaking down sweat, thus limiting odor formation.
What's the difference between a deodorant and an antiperspirant?
The main difference lies in the way they work. Deodorants target odors by neutralizing bacteria and perfuming, while antiperspirants generally contain aluminum salts that work by reducing perspiration by temporarily obstructing the sweat glands. In this way, antiperspirants help control both sweat and odor.
Are deodorants safe?
Deodorants are considered safe for most users. However, some ingredients, such as aluminum salts in antiperspirants, have sparked debate about their safety. Current research has not definitively linked these components to serious health problems, but it is advisable to choose alcohol- and paraben-free products if you have sensitive skin.
How do I choose the right deodorant?
Choosing the right deodorant depends on your personal needs and skin type. For sensitive skin, opt for alcohol-free and hypoallergenic formulas. If you're active, an antiperspirant deodorant may be more effective. Also consider fragrance preferences and ease of application (spray, stick, roll-on, etc.).
Can I use deodorant after waxing?
To avoid irritation, we recommend waiting at least 24 hours after waxing before applying deodorant. For particularly sensitive skin, choose a deodorant designed for sensitive skin or after shaving, which contains soothing ingredients such as aloe vera.
Are there natural alternatives to conventional deodorants?
Yes, there are natural alternatives such as deodorants based on baking soda, coconut oil, lemon or clay. These products use natural ingredients to neutralize odors without blocking perspiration, which may be preferable for those seeking to avoid chemicals.
How to avoid deodorant stains on clothes?
To avoid deodorant stains, apply a thin layer of product and allow it to dry completely before getting dressed. Opt for clear formulas or those specifically designed to leave no residue. Regularly washing affected areas of clothing with stain removers can also help.
Do deodorants expire?
Deodorants generally have a shelf life of 1 to 3 years. They should be kept in a cool, dry place to maintain their effectiveness. Check the expiry date on the packaging and note any change in the texture or smell of the product as a sign that it's time to replace it.
How do deodorants affect skin pH?
Deodorants can influence skin pH, which is normally slightly acidic to fight harmful bacteria. Alcohol-based formulas can make the skin more alkaline, promoting bacterial growth and odor. It's advisable to choose deodorants formulated to be compatible with the skin's natural pH to maintain its balance and health.
Can I use the same deodorant on my feet?
Although some deodorants are formulated to be used under the arms as well as on the feet, it's best to use a product specifically designed for feet. These products often contain antifungal ingredients to combat fungus, common on feet, in addition to antibacterial components to reduce odour.
What is the environmental impact of aerosol deodorants?
Aerosol deodorants have been criticized for their environmental impact, notably due to the use of propellants that can contribute to air pollution. Modern formulas use less harmful propellants, but alternatives such as stick, roll-on or cream deodorants are considered more environmentally friendly.
How to test skin sensitivity to a new deodorant?
To test skin sensitivity to a new deodorant, apply a small amount of the product to an inconspicuous area, such as the inside of the wrist, and wait 24 hours. In the event of redness, itching or other irritant reaction, discontinue use and consult a dermatologist if necessary.
What are the latest innovations in deodorants?
The latest innovations in deodorants include the introduction of probiotic formulas that promote the growth of skin-friendly bacteria. Other advances include streak-free deodorants, long-lasting formulations, and products that adjust to skin pH for personalized, effective odor protection.
