Deodorants: stay fresh during the summer

Why do we sweat more when it’s hot?

Sweating helps keep our body temperature around 37°C. Thus, as soon as it is hot, an actual thermoregulation plant starts up. Because we evacuate an average of 500 ml of sweat per day, secreted by the 4 million sweat glands that cover our face and body.

Other factors can intervene in excessive sweating: stress, physical exercise, fear, etc. And if sweat is initially an odorless liquid, it is its degradation by bacteria, naturally present on the skin’s surface, that causes the formation of annoying odors. Not to mention the painful sensations of humidity and the unsightly halos on the clothes.

However, with good daily hygiene and deodorants or antiperspirants, these minor inconveniences will only be a bad memory.

Ball, stick, or spray: which presentation to choose?

No product is more effective than another, and the choice of the presentation will instead be made according to the preferences and habits of each.

For example, a spray will provide a more straightforward feeling of freshness at the time of application, while sticks or balls, generally easier to use, will be easily transportable on weekends or holidays in a bag or suitcase.

There are now sprays in the pocket or compressed format.

The pocket (capacity: 100 ml) is offered by Nivea for a price of about 1.95 € in supermarkets; the compressed (i.e., twice as small as a conventional 200 ml aerosol) is presented at DoveMonsavon, and Rexona, with a selling price generally between € 2.85 and € 3.90 (depending on the formulas) and also sold in supermarkets.

This compressed format guarantees some uses equivalent to the conventional structure but with a propellant capacity half as high. A good gesture also for the environment!

Some products are deodorants, others antiperspirants. What’s the difference?

They do not, in reality, have the same action. The deodorant acts on the formation of odors through bactericidal agents (such as alcohol, essential oils, or zinc salts, for example) that prevent the degradation of sweat, or thanks to active ingredients (such as polysaccharides and sugar derivatives), which form a protective film on the surface of the skin to prevent bacteria from attaching.

Antiperspirants are intended to limit the evacuation of sweat through the skin’s pores, thanks to astringent active ingredients – such as aluminum salts – to limit the sensations of moisture. Other antiperspirants incorporate active ingredients such as perlite (which absorbs up to 350 times its weight in water) or clay.

What about alum stone?

Crystalline rock is naturally present in nature. Alum stone is an ecological solution to fight against excess sweat because it is an excellent astringent.

However, check that it is indeed a natural alum stone, which bears the mention “potassium alum” (you will find it in organic-stores and on the site aroma-zone.com at the price of 6.90 €), and not a synthetic stone (it then bears the mention “ammonium alum”).

You can use it in the armpits, feet, and hands to stop slight bleeding after a light cut, especially after shaving.

Some formulas claim effectiveness for 48 or even 72 hours… What is it?

The majority of deodorants offer effectiveness for 24 hours. But some products claim an effect over two or three days. This means that they are more effective in case of heavy sweating, during high heat, or during intense physical exercise.

It should never be forgotten that to fulfill their mission fully, deodorants or antiperspirants must be applied in the morning on clean skin. Their use during the day essentially serves to offer a little freshness.
