Freeze branding (sometimes called CryoBranding and the resulting brands, trichoglyphs) is a technique involving a cryogenic coolant instead of heat to produce permanent marks on a variety of animals. The coolant is used to lower the temperature of a branding iron such that its application to shaved skin will permanently alter hair follicles.
