ETTO is a range of "clean essentials" using Australian medicinal-grade tea tree and blue mallee eucalyptus oils from Western Australia's Wajarri Country and eastern Australia's Bundjalung Country, grown with regenerative farming practices. Founded in Western Australia by Andrea Horwood, former journalist and beauty entrepreneur, ETTO aims to create everyday products utilising the scientifically proven benefits of pure Australian native oils. Horwood describes it as a "first-aid/beauty hybrid," with products harnessing tea tree and eucalyptus oils to support skin health, reduce redness and alleviate dryness.
