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? 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: Penelope Cruz
We love Penelope Cruz's slicked back, classy look at the L.A. premier of "To Rome With Love." Her look on the red carpet is completely the opposite of her look in the film, in which she plays an Italian prostitute. (AP photo)
WORST: Emma Stone
The "The Amazing Spider-Man" actress had a fashion flop at the film's Seoul, South Korea premier. Having just been named <a href="http://www.huffingtonpost.com/2012/06/13/-jemma-stone-vogue-cover-july-2012_n_1594225.html" target="_hplink">Vogue's newest cover star</a>, we didn't expect to see her step out with an insect plate-like collar. Yikes! (GETTY)
BEST: Ginnifer Goodwin
Ginnifer Goodwin rocked bright pink lips at the Young Hollywood Awards. The "Big Love" and "Once Upon A Time" star looked magical with her signature pixie cut and an elegant while dress. We LOVED it! (AP)
WORST: Lisa Ling
Something about TV host Lisa Ling's makeup makes us cringe. Ling attended an intimate dinner benefiting Cedars-Sinai Women's Heart Center hosted by Barbara Streisand the star's home in Malibu. We love Lisa Ling, just not her makeup. (Getty photo)
BEST: Ashely Greene
"Twilight" actress Ashely Greene stepped out looking amazing at the Young Hollywood Awards this week. Love her steel-colored nail polish! (AP photo)
WORST: Niki Taylor
American model and former "Celebrity Apprentice" star Niki Taylor attended the 2012 New York Red Cross Ball with a very puffy 'do. Why would the 37 year-old opt for a helmet-like hairstyle that is only appropriate for a much older woman? Don't ask us! (GETTY)
WORST: Florence Welch
We love Florence Welch's unique style. She is one of the only ladies that can rock frocks like the one she wore to<a href="http://www.huffingtonpost.com/2012/05/07/met-gala-2012-red-carpet-arrivals_n_1497975.html" target="_hplink"> this year's Met Gala</a>, but something went awry at London's official opening of the Bulgari Hotel and Residences. We'd have been happy if our girl had a little more pop, instead of looking so washed-out. (Getty photo)
BEST: Cobie Smulders
"How I Met Your Mother" actress Cobie Smulders looking beautiful at the 2012 Crystal + Lucy Awards in LA. We love her soft makeup paired with that elegant up-do. (Getty photo)
WORST: Dita De Leon
Former Playboy model Dita De Leon's hair looking very oily at an LA premier of "To Rome With Love." Very oily. (Getty photo)
BEST: Hailee Steinfeld
Hailee Steinfeld looked ethereal at the Young Hollywood Awards on June 14. The young actress's wavy tresses were an elegant compliment to that glimmery, silver ensemble. (AP photo)
