Spray deodorant, stick deodorant, solid deodorant... which one to choose?

Deodorant is a hygiene product applied daily to prevent the onset of unpleasant odours. It is applied under the armpits, areas that often remain damp throughout the day. It is important to note that the skin in this area is delicate and often damaged due to frequent hair removal/shaving. Therefore, it is more porous to products which can then penetrate into the body. It is thus essential to opt for a natural deodorant made with ingredients that are respectful to health.

Unlike deodorants, antiperspirants block the flow of sweat.They also prevent bad odours by limiting perspiration and eliminating bacteria. They generally containaluminium salts, an ingredient that has been suspected to be harmful to health for several years.

Note:In everyday language, the term "deodorant" is used more frequently than "antiperspirant". Thus, we sometimes refer to aluminium salt deodorants, when in fact, they are antiperspirants.

Solid deodorant, spray, roll-on... There are various types of deodorants available on the market. Here are their specific characteristics:

• The spray or atomiser deodorant

This form of deodorant is valued for its convenience. Sprays are easy to apply and transport. In this form, the deodorant is more often an antiperspirant. It comes in the form of a fluid liquid that blocks perspiration thanks to the aluminium salts it contains. Upon application, it forms a dry powder under the armpits. Spray antiperspirants are often appreciated for the feeling of freshness they provide upon application. They are now available in mini format, to slip into your handbag or elsewhere.

Is spray deodorant harmful to the environment? Not anymore!The chlorofluorocarbons, released into the atmosphere by the transformation of certain gases present in aerosol cans, indeed contributed to the thinning of the ozone layer. However, since the early 90s, these gases have been excluded from aerosol cans (deodorants, hair sprays...). Thanks to this global action, the hole in the ozone layer has begun to significantly recover since the 2000s. According to specialists' predictions, the upper ozone layer above the Northern Hemisphere could be fully restored from 2030, while the gaping hole above Antarctica should disappear in the 2060s!

• The deodorant in cream form

If you dislike the moisture provided by a roll-on deodorant, consider opting for creams.New to the market, deodorant creams are recommended for sensitive skin as they often contain ingredients to hydrate and nourish the skin. They are also generally formulated without alcohol.

• The roll-on deodorant, with a ball applicator

Once applied, the roll-on deodorant helps to combat the formation of bacteria responsible for bad odours. Moreover, it often does not leave marks on clothing, unlike sprays.

• The stick deodorant

Also known as stick deodorant, the stick is the solid format of deodorant/anti-perspirant. It often contains nourishing ingredients such as butters and provides a pleasant and rich texture.

Thus, everything depends on the sensitivity of the skin and the sensations of each individual. In any case, if you have sensitive skin, be sure to use an alcohol-free deodorant, regardless of its format. Next, if you prefer a product that dries quickly, opt for a spray or stick. However, if your preference is for a product that does not leave white marks, you should lean towards a solid stick.

What about alum stone?Alum stone is not as natural as its name might suggest. In fact, it can sometimes be a 100% synthetic stone, manufactured from Ammonium Alum or synthetic Ammonium Sulfate, a by-product of the nylon chemical industry.In any case, whether natural or synthetic, alum stone contains aluminium salts, which we advise you to avoid as a precautionary principle.
