With technology changing at an ever-increasing rate, it's easy to forget how far we've come in such a short period of time. According to a theory called Martec's Law, technology changes at a rapid rate, which accelerates exponentially each year. And with each change, our expectations increase. In other words, as better products come out, we get used to them quickly and then demand more. So rarely do we stop to appreciate what we already have.

Beauty inventions are no exception. As beauty reporters, we're on a perpetual hunt for the next genius skincare procedure, gadget, or hair tool. But today we thought we'd do something a little different and take a look back at the beauty inventions of decades past.

What we ended up finding was utterly spellbinding… and a little bit freaky. According to old photographs, advertisements, and newspaper clippings, some of the beauty gadgets of the late 19th and early 20th centuries were utterly medieval. It really is impressive how far we've come in less than 100 years.
