Before, a deodorant was a rather basic formula and not always very effective. But today, new compositions are available to stay cool and limit the risk of moisture under the arms.
A good deodorant prevents the FORMATION of haloes.
Unlike anti-perspirants (with aluminum salts), deodorant uses plant or mineral assets to absorb moisture (corn starch, talc, perlite, kaolin, silver or magnesium oxide), which act both as mini sponges and As an odor absorber, as they degrade perspiration.
It limits bacterial development.
Active agents neutralize the bacteria on the surface of the skin, causing unpleasant odors. Essential oils are found in organic formulas (sage, rosemary, thyme, palmarosa, mint, clove, tea tree). But also the glyceryl caprylate and/or alcohol that destroys these bacteria. In conventional déos, it is zinc and triethylcitrate that play this role, and now magnesium oxide that accumulates absorbent and antibacterial power.
A good deodorant masks the odors.
For a long time, this was the only action of deodorants: to cover odors with powerful fragrances of synthesis or, in bio, a cocktail of essential oils.
Now, when there is perfume, it is for the pleasant side, or in addition for a more global action against perspiration.
It does not attack the skin.
If you have sensitive or easily irritated skin, you should preferably choose a formula without alcohol and propellant, as well as essential oils, potentially allergenic. and prefer deodorants enriched with soothing and moisturizing ingredients, such as glycerin, bisabolol or thermal water.
