If your cosplay involves prosthetics, liquid latex is a wonderful adhesive to make it stick to your skin. Besides keeping the prosthetic in place, you can blend in the edges of the latex with makeup for a more seamless look. Cosplayer Danielle Beaulieu reviewed the process from choosing liquid latex to removing it. She stresses that it’s an easy skill for a beginner to pick up and learning how to use the material opens up new cosplay doors. She recommends clearing all hair away from the area you want to apply the liquid latex and working with disposable makeup sponges (it will wreck brushes). Once you’re ready to apply your prosthetic, do the following:
When you are finally ready to put your piece on, glob the latex all over the part of the prosthetic that will be touching your skin. Now, apply the prosthetic to your face exactly where you want it to be positioned. Don’t worry if you miss your mark, you can adjust the piece for a short amount of time but it is not wise to mess around with it too much. When you have it where you want it, take either your q-tip or makeup sponge and dab some latex around the seams of your piece, so you have the liquid latex on both the prosthetic and your skin around it. Now, wait for that layer to dry. This is where it helps to have a friend. Your arm will get pretty tired, but try not to lift or wiggle the piece or you will make it harder on yourself to get the piece to dry in place. Try not to pull at the latex, you could ruin it, and by now you definitely won’t want to start over.
She also goes over applying multiple layers and blending it into your makeup. Read the entire tutorial at White Rabbit Costuming.
