What is the best way to add some blood on the character player face ?

I don’t want a blood splatter effect or death effect. just some blood-like injuries effect. not even animated or maybe with some animation but the main goal is to show some blood like after a crash nothing with death or blood splatter.

I tried to google for: pc game blood injuries or pc game character blood injuries but nothing much like what I need.

In my game, the character is waking up after a crash and I want to add some blood on his face something realistic.

I tried on youtube to search for: unity3d blood injuries but all I get is shooter games screenshots with death blood or splatter blood.

Make a second set of materials and change it when it is appropriate. You can google it how to change a material on a skinned mesh.
