It's been a whirlwind month in the beauty biz: we witnessed a model speak up, a beauty staple go green, a toxin turn ten and some guys go bare. Read on to find out what made our latest hot list. 

We've heard of apple notes in fragrances, but never quite like this. For an upcoming exhibition, a collaborative artists' group has commissioned a fragrance that captures "the scent of an Apple product being opened for the first time." What's it smell like? According to the perfumer's blog, "The scent features the smell of the plastic wrap covering the box, printed ink on the cardboard, the smell of paper and plastic components within the box and of course the aluminum laptop which has come straight from the factory where it was assembled in China."

In honor of its 10th anniversary this month, we delved into the history of Botulinum Toxin Type A, from its humble beginnings in a spoiled sausage to its current status as injectable-of-choice to celebrities like Jenny McCarthy and Simon Cowell.

Chin augmentation is the fastest growing cosmetic procedure, says the American Society of Plastic Surgeons, who released 2011 statistics this month. With a 70 percent increase last year, chin implant procedures grew more than boob jobs, Botox and liposuction combined. The reason? Video chats are making people more self-conscious about their double chins, experts claim.

Earlier this year, we predicted that 2012 would see more fashion designers get into the beauty game. Now it’s happening: Vera Wang recently launched a 74-piece Simply Vera cosmetics line at Kohl’s. Marc Jacobs is working on a makeup line with Sephora. And a new Calvin Klein-branded CK One Color Cosmetics line is hitting beauty counters in limited U.S. distribution now.

With a MAC campaign and an OPI nail polish collection already under her belt, it was only a matter of time before Nicki Minaj started hawking a fragrance. This month the rapper signed a deal with Give Back Brands LLC, the same company who makes Justin Bieber’s Someday. Net profits will go to a yet-to-be-named charity.

Maybelline has tapped pink-haired model Charlotte Free as its newest face. Her TV ads debut this August.

In honor of Earth Day, we asked “green manicurist” Jenna Hipp for pointers on avoiding toxic ingredients in your nail polish and remover.

The Los Angeles Times recently reported on a "troubling trend": teenagers are drinking liquid hand sanitizer to get drunk. Apparently, Purell and its ilk can be distilled into 120 proof liquor via a process detailed on - where else? - the internet.

Behold: the Rorschach manicure by blogger Maegan Tintari, which we spotted on Stylelist. We’re kind of obsessed. What does that say about us?

June 2 marks Queen Elizabeth II’s Diamond Jubilee (that’s 60 years on the throne to commoners like you and me), and plenty of beauty brands are marking the occasion with limited-edition releases. Luxury perfumer Clive Christian is releasing a $1300 Imperial Jubilee edition of his signature No. 1 fragrance, Bond No. 9 is collaborating with Harrods on a commemorative scent and Butter London has launched a sparkly lacquer crowned “Lillibet’s Jubilee.”

In crazy diet news, the New York Times recently profiled brides who have had a feeding tube inserted for 10 days in order to lose weight for their weddings through a process known as the K-E (ketogenic enteral) diet. To that acronym, we’d like to add a few letters: WTF?

The left side of your face is probably your "good side," according to a new study published by Wake Forest University researchers. Test subjects presented with photos of faces shown from different angles consistently rated the left side as more "pleasant." "Our results suggest that posers' left cheeks tend to exhibit a greater intensity of emotion, which observers find more aesthetically pleasing," the research team said in a statement.

We’ve heard of maternity leave, maternity pillows and even maternity Spanx, so how have we missed out on maternity nail polish until now? Fashionista recently interviewed the founder of Knocked Up Nails, a collection of lacquers with formulas safe for moms-to-be and their babies. The best part? The shade names, which include O-Blue-GYN, Preggers in Pink and One Glass a Week (a cabernet-colored polish).

Coco Rocha is not happy with Elle Brazil. The model took to her Tumblr recently when she learned that the magazine Photoshopped her cover to make it appear as if she were showing more skin than she actually was, in violation of her no-nudity policy (and contract). "I strongly believe every model has a right to set rules for how she is portrayed and for me these rules were clearly circumvented," Coco wrote.

As part of Procter & Gamble's mega-sponsorship of the upcoming Olympic Games in London, the company is signing basically all the hot athletes to represent its family of beauty brands. In the U.S., beach volleyball team member Jennifer Kessy and women's boxing competitor Marlen Esparza will appear in ads for CoverGirl, while swimmer Natalie Coughlin and her glorious mane will rep Pantene. USA! USA!

Hey guys, sparkly crystals affixed to freshly waxed nether regions aren't just for Jennifer Love Hewitt anymore. The New York Times recently got up close and personal with the male Brazilian waxing trend, including a mention of "pejazzling" - vajazzling's manly counterpart. It's available at Bliss spas, FYI.

Beyoncé is having quite a year. After giving birth to the world's most fabulous baby in the world's most beautifully redecorated hospital ward, then starting the world's most anticipated Tumblr, the singer has been crowned by People magazine as - what else? - the World's Most Beautiful Woman. Bravo, B.

If you've coveted Carine Roitfeld's smoky eyed look, get ready: the former French Vogue editor is collaborating with MAC on a makeup collection set to launch this fall. The lineup will include 20 pieces, with a focus on Carine's signature eye liner, bold brows and nude lips.

Is it just us, or are beauty product film tie-ins becoming ubiquitous? The latest: OPI's polish line that pays homage to The Amazing Spider-Man, the film to be released by Sony Pictures in July. The limited-edition collection includes six shades with names like Your Web or Mine? and My Boyfriend Scales Walls, plus a green shimmer Shatter coat dubbed Shatter the Scales. The line launches in May.

These days you can get a "facial" for your back, butt or vajayjay - why not your mouth? Dr. Jennifer Jablow, New York-based dentist to celebrities and models, has created the Tooth Facial. The three-step treatment includes a pre-whitening polish, an hourlong whitening session and an antioxidant-infused antiaging treatment for teeth and gums.

“It was revolting. It was long and coarse and black," said Anna Faris on the Tonight Show of the underarm hair she grew to play an organic food store owner in The Dictator. "If I really wanted to shock and gag people, I would show off my armpit hair at parties. It was remarkable."

Though she still has yet to live down that vajazzling confession, Jennifer Love Hewitt now swears by another questionable beauty staple: vanilla extract as perfume. "I carry McCormick's Pure Vanilla [in my purse] -- the baking kind -- and dab it on my neck," she told Us Weekly. "Men are attracted to the scent! One time, I put it on and four different guys were like, 'You smell amazing!'"

Forbes recently ranked the top 10 global beauty brands, which together are valued at around $60 billion. The number one name in the biz? 60-year-old Olay, with a value of $11.8 billion. That's a whole lot of Regenerist serum.

After months sporting her Girl With the Dragon Tattoo black bangs, Rooney Mara has been rendered unrecognizable with a new blonde/red ombre ‘do that she’s wearing for an upcoming role.

As a followup to their recent fragrance launch, the New York Yankees are expanding into a full line of beauty products which includes bath sets, scented plastic bracelets and dog tags and lip gloss.

Heidi Klum wears nothing but technicolor stripes in her new ad for Astor Cosmetics. It took 12 hours for makeup artist Joanne Gair to paint the supermodel's body.
