The Pimple Detection Device is a modified helmet designed to wipe out pimples before they happen with a very miniature heat seeking missile. Once the missile destroys a pimple, it leaves behind a Band-Aid.
When Egon Spengler's age was reversed after an accident involving the Clock Ghost, he invented a Pimple Detection Device shortly after. He demonstrated it at breakfast and used it on himself. Not garnering the accolade he wanted, Egon stormed off.
