Freckles Frozen Off With Dry Ice (Feb, 1933)
I’m going to guess that freckle used to be synonymous with mole. Otherwise, this could take a while. Also, I love the assumption that readers are all white.
Freckles Frozen Off With Dry Ice
FREEZING off freckles by means of pencils of compressed carbon dioxide snow, often called “dry ice,” is a new method of getting rid of these skin blemishes devised by an Italian physician, Dr. M. Matarasso. The dry ice, which will freeze all human tissues solid after contact of more than a few moments, is compressed into a small stick or pencil, sharp-pointed like a lead pencil. The point of this pencil of concentrated cold then is pressed against each freckle in turn for three seconds. After the colored skin of the freckle drops off in about a week, the new skin thus disclosed is white and unmarked.
