Waxes and Silicones allow you to create gashes, wounds, molds and creepy effects without any special prosthetics or molds. Silicone is a lightweight material that is easy to mold and sculpt and will adhere to the skin for hours without adhesive. Silicone is ideal when creating larger effects on the face and for those allergic to latex. Waxes create fast 3D effects and are easy to work with because the heat of your hands makes them pliable. Waxes differ from Silicone because they are heavier and do not dry , they will remain flexible where Silicone will dry to a stay put finish.
