Sure Deodorant: Under the Cap [Part 4]

Ah, deodorants/antiperspirants. What an interesting part of our ‘skincare’ routine that most of us don’t even think twice about. You likely use one or the other to prevent sweat or to cover up body odour. 

➔ But why do we sweat?

Sweating can happen for a variety of different reasons – a reaction to heat, stressful situations, spicy foods, infections. It's basically our body's way or regulating our temperature. We don’t just sweat from our armpits – concentrated sweat glands can be found in our palms, soles, and scalp.

Of course, excessive sweating can be an indication of a deeper health issue, but for run of the mill sweating did you know that sweat itself doesn’t smell? Research shows It’s only when bacteria feast on the fatty oils in sweat, that they produce the bad smelling gases we think of as ‘body odour.’ More than 6 types of bacteria have been found in armpits – each with a different purpose and ‘smell.’

➔ Do we all have different levels of body odour?

You probably already know the answer to this if you have a smellier sibling or significant other, but yes. Men don’t necessarily have more sweat glands than women, but they do have more of a bacteria called Corynebacteria, which are known to be particular stinky. Some people even have little or no body odour at all because of particular genotypes (for e.g. this is particularly true in East Asia).

➔ So what's the big difference between antiperspirant or deodorant?

Simply put – deodorants are for covering up smells, and anti-perspirants are for covering up sweat. Deodorants prevent the smell of body odour either by masking it, or by using anti-microbials to kill the bacteria that cause the smell altogether. Antiperspirants on the other hand prevent the ‘wetness’ from sweat by blocking the ducts and glands that produce the sweat to begin with. They often contain aluminium salts like aluminium zirconium or aluminium chloride. In fact, in some parts of South Asia and the Middle East, pure Potassium Alum (or crystal rock, Fitkiri) is used as an antiperspirant. 

Though many fear that antiperspirants lead to breast cancer or alzheimer’s, we couldn’t find any conclusive evidence to support the claim (link to National Cancer Institute here). The one thing that has been proven is that those who don’t use any under-arm aids have more Corynebacteria than those who have been using deodorants/antiperspirants for a long time. Some also claim antiperspirants are irritating, and cause a burning sensation leading to swollen skin.

When choosing what to use, think about what actually bothers/affects you – the smell of body odour or the ‘wet’ feeling from the sweat itself?

➔ How do I choose between a roll-on stick vs. spray-on deodorant?

Some argue that aerosol sprays have negative environmental effects (and you can inhale the chemicals while applying), but the pros are they tend to dry quicker (no stains), and you can share. On the other hand, roll-on sticks are better for travel and might offer ‘stronger’ antiperspirant protection.

We’re reviewing a roll-on stick this week and will share an aerosol spray in the coming weeks!

When in quantities of .01% or greater, these fragrance components need to be listed out separately because the IFRA (International Fragrance Association) deems them to be allergens.

Now that you know what some of the ingredients in your deodorant do, have a look at what's in your products. Over time you'll get familiar with why each of those ingredients are in there and can spot some unnecessary filler ones. 

It'll take time to learn but trust us it's worth it -- you'll armour yourself with the knowledge to cut through a lot of false marketing claims.

Most people use some form of moisturiser, or are familiar with what it “does” i.e. moisturise the skin. The composition of your skin’s outer layer – the stratum corneum – is affected by environmental factors, age, and even genetics. If you shave often or your face is otherwise irritated, your moisturiser can help soothe or calm the skin as well.
