Original Blistex Lip Ointment with proprietary oil emulsion process
The brand was originally a single product that was an ointment developed by a pharmacist.
In the early part of the 20th century in the USA, it was not unusual for pharmacists to concoct their own products, especially for non-prescription items such as miscellaneous healing remedies and cosmetics. The original ointment formula proved remarkably effective for helping to treat cold sores, a viral condition that primarily affects the skin on and around the lips. The ointment also proved to be effective for other lip issues such as dryness and cracking of the lips. Following development of the product, the “Blistex” name was trademarked in 1939.
