Most antiperspirants work by clogging pores with aluminium salts. Aluminium in our armpits? No thanks. MooGoo feel that aluminium belongs in our roofs, not under our arms! Our formula works by allowing perspiration, which is odourless, and controlling odour causing bacteria. No bacteria, no smell. This aluminium-free, roll-on, natural deodorant has a slightly alkaline formula that prevents odour causing bacteria from growing. It's free from over-powering essential oils that mask odour and can cause irritation. Made with Milk of Magnesia and a light, fresh Lemon Myrtle scent, it's naturally preserved with Hops Extract – free of Parabens and Phenoxyethanol. For use, give the bottle a shake and apply liberally to the underarm area. Allow the skin to dry before applying. Always read and follow the directions for use. If irritation occurs, discontinue use and consult your healthcare professional. It's recommended to patch test this product before full use.
