We spend lots of time focusing on what stars wear (and any wardrobe malfunctions they may have), but what about what they put on their faces? There's been a lot of news lately about makeup companies and although makeup may not seem important, plenty of women won't leave home without it.

In a survey, two-thirds of British women said that heading to the office bare-faced caused them more stress than public speaking, going on a first date or enduring a job interview. 91 percent of women surveyed would rather cancel a first date altogether than go without makeup on. And in the U.S., women spend around $7 billion on cosmetics every year.

And that doesn't even include hair.The AP recently reported that in 1950, about seven percent of women dyed their hair. Today? 95 percent or more.

With all that beauty-obsession (and our own love of makeup) in mind, we're taking a look at This Week In Beauty. From this week forward, we'll be showcasing the best, worst and most interesting styles of hair, makeup and nails that we came across this week. Take a look, get inspired and vote for your faves!

  • BEST: Keira Knightley

    We LOVE Keira Knightley's makeup at the premiere of "Seeking a Friend for the End of the World" in L.A., on June 18. Since her dress was mostly nude with vintage-like embroidery, using neutral shades for her face was the best choice. The crown of red leaves on her loosely-braided up-do made an excellent accessory to complete her outfit. (AP photo)

  • WORST: Kristen Stewart

    We're not exactly sure what happened to Kristen Stewart's hair at the Australian premiere of "Snow White & The Huntsman," on June 19th. Stewart obviously didn't realize that a bird had started a nest in her hair and decided not to do anything about it. (Getty photo)

  • BEST: Natalie Zea

    Natalie Zea's orange tint lipstick and amazing, exotic earrings match perfectly with her sun-kissed skin. Channeling a mediterranean goddess, the actress looked stunning at the Broadcast TV Journalists Association Critics' Choice Awards in Beverly Hills, CA. (Getty photo)

  • WORST: Jessica Szohr

    Actress Jessica Szohr has been known to have some fashion flops <a href="http://www.huffingtonpost.com/2011/11/22/jessica-szohr-emmys_n_1107972.html" target="_hplink">up her sleeves </a> but at David Lynch's cocktail party on June 20th, her fashion was good. Her beauty, on the other hand, wasn't great. In fact, Szohr looked really shiny -- almost greasy -- and greasy is never good. (Getty photo)

  • BEST: Kelly Osbourne

    The "Fashion Police" star looked really great at David Lynch's Cocktail Party in Hollywood on June 20th. We loved how Osbourne's purple hair -- not an easy thing to pull off! -- looked surprisingly sweet as she opted for a matte look with clean, black eyeliner and rosy cheeks. This fashionista, who is<a href="http://www.huffingtonpost.com/2012/06/14/kelly-osbourne-without-makeup-pajamas_n_1596685.html" target="_hplink">not afraid to go makeup-less</a>, also decided to make a political statement by wearing an "Obama 2012" pin.

  • WORST: Cher

    Oh Cher! The "Burlesque" star and singing legend did not look her best at the premiere of "The Magic of Belle Isle," on June 20 in Los Angeles. Her signature jet-black hair looked a little crazed and it didn't help that her eyeshadow looked as if it had been put on in a hurry. Not a good look for the "Goddess of Pop." (Getty photo)

  • BEST: Lucy Lui

    The "Charlie's Angels" actress looked elegant and refined at The Critics' Choice Television Awards on 18 June, 2012. We love her simple makeup and low up-do -- not to mention that dress! (AP photo)

  • WORST: Melissa George

    Australian actress Melissa George looked a little frightening at a special screening of "To Rome With Love" in New York City on June 20. She was already wearing a black and white ensemble, so opting for very black eyeliner on her top and bottom lids was not a good choice. (Getty photo)

  • BEST: Olivia Munn

    Olivia Munn looked radiant at HBO's "Newsroom" Premiere in Hollywood on June 20. The actress, model and former TV personality matched her sun-kissed tan with gold makeup and a very sweet, pink lip. Love it! (Getty photo)

  • WORST: Emily Mortimer

    The actress looked a little washed out at the LA premiere of her new show, HBO's "The Newsroom" on June 20 in Hollywood. We would have liked to see her add a little lip color or maybe a bolder eyeshadow to spice up her look a little. (Getty photo)
