Finding ways to remove scars has been around since ancient Egypt when physicians would use sandpaper to scrape off blemishes. But there is a worse method from the past.

In the early 1900s, a German dermatologist decided a 'better' way to remove scars would be by using blades spinning at high speeds over your chemically hardened skin. The machine would blast layers of skin right off, however the downside was intense pain, potentially more scarring and infection.
