"I'm a self confessed coffee addict so I was regularly seeing yellow tinge stains on my teeth. After using the activated charcoal powder every day for 2-3 minutes, within 2-3 days I noticed a massive difference in the colour of my teeth. My teeth are at least 5-6 shades whiter and most stains have now been removed. After 7-8 days of continous use is when I saw the best results. I will be ordering my second jar over the next week or so! Extremely happy so far :)" - Milly Powell.
