So how does one application last a minimum of 15 days?
Short answer: Elkye is designed to work on the cause of underarm odour instead of covering it with scent. Here's the thinking behind it.
Odour starts with bacteria
Underarm odour is associated with microorganisms on the skin interacting with components of sweat — producing the compounds we recognise as smell.
Fragrance only hides it
Most deodorants add perfume over the top. As that scent fades through the day, the underlying odour returns — which is why they're reapplied every single morning.
Elkye targets the source
Rather than masking, Elkye is designed to help control the bacteria responsible for producing underarm odour — addressing the cause, not the symptom.
Control lasts, so protection lasts
Because it's built around managing the cause instead of a scent that wears off, a single application is designed to keep odour in check for a minimum of 15 days.*
