Industry Group Profile - Lead Exposure. Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earthâs crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker). In 2012, U.S. production of lead was estimated at 1.6 million metric tons; primarily from secondary refining of scrap metal.
Razor burn is a temporary skin irritation caused by shaving. Different people get razor burn for different reasons, but most of the time, it has to do with shaving too closely, too forcefully, or with a dull razor. It is usually identifiable by the itchy red bumps it leaves behind, and in most cases, only lasts for a few days.
One of the best tools you can use to help prevent razor burn is a shaving brush. A shaving brush does a couple of things. First, it helps raise the hair so that a closer cut is possible. Second, it helps create a rich creamy lather with the shaving cream that stays close to the skin.
