People only now realising how to actually use deodorant as common mistake 'decreases effectiveness'

As the temperature rises, it’s no surprise that more folks are carrying around their deodorant for quick refreshes throughout the day during the summer heat. But, if you’re simply slapping on another layer whenever you think it's necessary, you're doing it wrong.

Co-founder of natural deodorant brand Make Waves, Oliver Batiste, is setting the record straight: "Many people are making the mistake of reapplying their deodorant throughout the day. On hotter days you may be tempted to add another layer of your chosen deodorant, but this won't always have the desired effect.

“Applying deodorant over your old deodorant from earlier in the day without first cleaning your underarm can lead to decreased effectiveness and, in some cases, cause irritation due to product build-up.”

For those looking to top up their deodorant during the day, Batiste recommends a healthier method that won't compromise your wellbeing or leave you smelling less than fresh. He said: "If you feel that your deodorant needs to be reapplied, first clean your underarms as best as possible using warm water or a wet wipe.

"This will help you feel much fresher and ensure the product you're using can be as effective as possible." It's also wise to monitor the amount of deodorant you use each time.

Aerosol deodorants can be particularly misleading in this as some people keep spraying until they notice the smell properly, but this is actually far too much. Oliver recommended doing three swipes at a maximum. Roll-ons have a similar issue as people mindlessly pack on the product not realising how much is sitting on their skin.

The expert warned: "It always amazes me how often people are overusing their deodorant, with some applying between five and 10 swipes of deodorant to each underarm. When applying a roll-on on you should only be using between two and three swipes of the product per armpit."

He explained that using too much deodorant, much like reapplying directly on top of old layers, can create an excess build-up of product on the skin. This takes longer to dry, which may mean it seeps onto your clothes and causes stains, all while not doing you much good in the first place.

Oliver continued: "Despite what many people seem to believe, using more deodorant will not increase its effectiveness. For best results and to on how often you need to repurchase your deodorant, stick to the two-to-three swipe rule."
