Tawas Crystal Deodorants are sourced from natural potassium alum (nothing to do with aluminium) formed from non-toxic materials in the earth.  This is the genuine original Tawas Crystal, from the Philippines, which locals have used for over 500 years to eliminate body odour.  The crystals are really simple to use, you simply apply the crystal to wet skin (or wet the crystal first if using on dry skin), allow to dry, and a little of the crystal will dissolve, leaving an invisible microscopic layer of crystal on the skin which eliminates the bacteria that cause body odour.  The molecular structure of the crystal is too large to pass into the body, so it will simply remain on your skin, doing it’s job for up to 24 hours, or until you next bathe or shower.  No blockage of the pores, your body can breathe and sweat as it should, but without any embarrassing odour.  Use for underarms or feet – it’s brilliant on foot odour, no more cheesy feet!  As it contains no perfumes, alchohol, preservatives, emulsifiers, oils, aluminium chlorohydrate – linked to Alzheimers and cancer (check your regular Deodorant ingredients) or parabens (linked to breast cancer), it’s totally safe to use and it’s also ideal for sensitive skin and those with allergies, and you won’t end up smelling of a toiletries department all morning either.  As each crystal will last for around a year, you can even save money!  Be Earthwise!
