Collodion is a classic product for creation of simulated scars (also known as Scarring Material).
Collodion, which dries extremely fast, is first coated onto the skin. The skin is then pressed together to form a fold. The optical impression of a scar results.
Collodion contains ether and acts to degrease the skin. After being used, the skin should be treated with cream that contains fat, and the skin should be protected from being stressed.
