Deodorant or Antiperspirant?

Both an antiperspirant and a deodorant are used to combat unpleasant odors. However, they differ in their mode of action.

The antiperspirant fights perspiration odor by blocking sweat. It reduces perspiration through ingredients such as aluminum salts. When these compounds are applied to the skin, they precipitate and combine with dead skin cells, forming plugs that clog sweat glands, blocking the flow of sweat. In addition, aluminum salts are bactericidal. They fight the proliferation of bacteria that are found en masse in the armpits and are the cause of bad odors. A deodorant serves to mask or prevent the appearance of unpleasant sweat odors by absorbing moisture thanks to its ingredients (talc, kaolin, magnesite...). Deodorant also prevents unpleasant odors by killing the bacteria on the surface of the skin. However, deodorant does not contain aluminum salts; it does not prevent sweat from draining naturally through the pores of the skin.

As for the form, deodorants and antiperspirants come in various forms, from solid stick to roll-on to spray or deodorant cream.

Note: In colloquial language, the term "deodorant" is used more frequently than "antiperspirant". Thus, people sometimes talk about a deodorant with aluminum salts, although it is actually an antiperspirant.

It depends on your sweat flow and the degree of discomfort it causes in your daily life!

Thus, people who sweat excessively and who are particularly bothered by it may be more likely to use an antiperspirant. However, the aluminum salts or aluminum chlorohydrates contained in antiperspirants are suspected of promoting the development of certain diseases such as Alzheimer's or breast cancer. To date, no scientific study has linked Alzheimer's disease to the repeated use of antiperspirants. Several studies have linked the presence of aluminum salts in breast cells to the development of malignant tumors and thus breast cancer, but mainly in animal models (mice). As with all skin care products, antiperspirants are subject to various draconian safety criteria. They are also subjected to rigorous testing before they reach the market.

For low to moderate perspiration, you should rather use a deodorant for precautionary reasons. Nevertheless, make sure that your deodorant does not contain irritating compounds (even more so if you have sensitive skin) such as alcohol. Also avoid compounds suspected of disrupting the hormonal system, such as triclosan or even parabens.

Note: People prone to heavy sweating can resort to detranspirants, which are sold only in pharmacies or online.
