Rigid Collodion is a clear liquid that when dry, puckers the skin to create the appearance of a scar. To apply simply draw a line, with the included brush, to "fleshy" skin. This allows the product to pucker the skin (if the skin is too tight, the scar will not be as successful). For deeper scars, apply several coats after each previous has dried. To create an old scar, use a medium brown pencil and lightly put colour down the middle of the scar. Use a brush to blend and soften the colour. To make a fresher scar, apply a pink colour and blend. This will also eliminate any shine. Remove by peeling off. Use Spirit Gum Remover to dissolve any remaining product followed by soap and water.
