Make-Up and Costume

 Creating Gore

Scars 

This would be useful to use within a flashback scene to connect the victim (if they survive) to before/during and after they experience the attack.  
(Made using eyelash glue and foundation.)

Burns
This would be useful to use if we chose not to follow the route of conventional gory deaths and decide to opt for burning injuries instead.
(Made with theatrical wax, paints, optional fake blood.) 
 

Cuts

This would be useful to use if we chose to feature our injuries in a house/school/hospital environment and our character fell through glass or was struck with a object that could shatter. This would also be easiest to duplicate on a large scale to include an entire face and also to create the illusion of skin sliced by glass such as in Suspiria.
(Made using theatrical wax, foundation, fake blood and plastic.)
