A spooky eyebrow scar can be easily emulated with basic costume makeup elements. Even thespians or aspiring zombies without an extensive background in theater makeup can achieve a convincing final effect. According to Eagle News, scars, bloodshed and gore are always in style for Halloween costumes. Prior to applying a fake skin scar for a night, place a dab of the paste on the inner wrist for about 10 to 15 minutes to rule out any possibility of a latex allergy.
Wash and dry the face thoroughly to remove any excess oils which can interfere with the costume makeup. Grab a dime-sized amount of the fake skin paste and work it briefly between your fingers to slightly warm the substance. Mold the paste into the desired shape and size of the eyebrow scar.
Apply the scar directly to the desired position in the eyebrow. Press the fake skin firmly onto the face, ensuring the paste sticks between the hairs of the eyebrow. Use your fingers or the tail of the foundation brush to reshape the scar if it was affected during this process.
Cut out a small piece of tissue paper and adhere it directly to the fake scar, if a thicker scar is desired. Applying tissue paper between layers of fake skin lets you build up the scar for a more dramatic final effect.
Dip the bristles of the foundation brush into the light, powdered foundation and completely coat the liquid skin, blending slightly into the areas of the face surrounding the fake eyebrow scar. Apply a small amount of dark, liquid foundation to draw attention to the scar, and finish with a coat of dark, powdered foundation.
