The wounds on each side of the mouth, were made using a thick "base - mix" consisting of liquid latex and little pieces of toilet paper (the proportion depends on the type of softness you'd like, the idea is to achieve a dough type consistency).
I recommend making the shapes of the wounds before you start applying the makeup, then it"s all a matter of letting the latex dry and applying using latex as a glue (don't apply the latex pieces too close to the mouth so the person can speak and laugh freely).
Like I said before applying the latex pieces you'll need to start applying the white foundation. I applied a light coat of latex on the skin and then asked the person to make funny faces so the dry coat of latex would crack a little and make the surface look rough. Don't forget to do the same all over the latex pieces on the person's face.
Then,after you've done this; apply a light base or white powder, I used Maicena (yes, the one you cook with!). To make the face look even more cracked and achieve longer duration on the makeup, after you finished powdering the face, tell the person to close their eyes and spray hair spray. As it dries it gets a better look on the face.
With the foundation on, it's time to proceed with the eyes, use a black cheap eyeshadow all over the eyebrows, on the eyelids and under the eyelids as if you were applying the eyeshadow forming a "panda eye pattern".
To finish the look use a thin red lipliner and red lipstick ( be choppy about it, you don't want it to look like you carefully did it...and remember to apply lipstick and lip linner on the latex pieces) .
There you go...that's it! if you want further explanations you can always ask, I'd gladly answer everything you'll need to know.
