Celebrity Contest
Split teens off into partners. The goal here is to create a "celebrity look" using makeup on your partner and then have the rest of the group guess who you've tried to emulate. To take the game further, have each guest dress up as the celebrity. For example, glittery eyeshadow, rosy cheeks and pink lipstick make a perfect Hannah Montana. Red lipstick, dark eyes and temporary tattoos will have everyone guessing Angelina Jolie. There are endless celebrities with signature looks to re-create.
No Mirror Makeover
Give each teenager a small stash of makeup, including mascara, lipstick, eyeliner and blush. Without a mirror, everyone does her own makeup. This is sure to provoke a lot of giggles, and the winner is the person with the most perfect (or silliest!) look. Make sure to take plenty of pictures to show off your handiwork.
Animal Parade
This game requires a lot of makeup, but is great for letting teens artistic sides run wild. Pair off again, and each teenager uses makeup to turn her partner into a wild creature. Use plenty of eyeliner for an exotic cat look, or dot plenty of black eyeliner and white shadow on the face for a cute dalmatian puppy. Experimenting with different animal faces is also a great way to come up with creative ideas for Halloween.
