1) What deodorant or antiperspirant?
First, we make the difference between deodorant and antiperspirant. Currently one product combines both functions, although in the past there were two different products.
• Deodorants mask the smell of sweat limiting the proliferation of bacteria responsible for these odors;
• Deodorants Antiperspirants block the sweat glands and sweat secretion limit. The downside is that interfere with the natural process of maintaining body temperature at 37 °.
For those who suffer from excessive sweating, antiperspirants are more effective than products that only cover up the odors. However, there are deodorants that combine both actions: blocking and concealing perspiration odors.
2) With or without aluminum salt?
Most deodorants containing aluminum salts, which have antiperspirant properties; a few years ago, a controversy arose regarding the health risks of these salts. But even if they have been linked to breast cancer, no study has shown definitively that relationship.
After the fear caused by these suspicions, certain brands have sought an alternative to aluminum salts, for example, alum stone.
The spray bar or a matter of personal choice. Although there is a small difference: the rod has a much higher concentration of aluminum salts and therefore is more effective than sprays. However, aerosols produce a feeling of freshness much more immediate and intense than the bar.
4) Beware of the intolerance of the skin
if you have sensitive skin, you should pay more attention when choosing the product. Deodorants often contain alcohol (for perfume, conservation and as an antiseptic agent) and this tends to dry out or irritate the skin. The proof is the heat that is felt in the armpits just plucked when they are sprayed with spray. Antibacterial and antiseptic substances containing deodorants, as well as essential oils for fragrances can also cause allergies. To avoid unpleasant surprises, you have to get used to reading the list of components in the package.
