If you use this product according to its directions (and patch test — always be sure to patch test!), it shouldn't have any ill effects on your skin. However, it can be poisonous when ingested, so take care when (or, indeed, if) you decide to use it as a homemade toothpaste. Also, make sure to watch out for fakes: Due to its popularity, numerous frauds are circulating knock-offs which can be very dangerous to your skin — yikes.
