Golden Globes 2011 Fashion Trends

Pretty in Pink and Red or Dead

Save: Julianne Moore in Lanvin, Julianna Margulies in vintage Yves Saint Laurent

Skip: January Jones in Versace

Don’t get us wrong, January Jones looks great and men probably got a lot more interested in the red carpet after seeing that dress; but the line between vamp and tramp is thin and we’re not sure how many women would be able to toe the line in this dress or any “inspired by” designs.

Would you buy acne treatments from this face? Proactiv is betting you will.

Bieber joins Jessica Simpson, Jennifer Love Hewitt and Rolling Stoneâ€s September cover girl Katy Perry among other Hollywood types that have served as celebrity faces for the brandâ€s acne-fighting products.

Greg Renker, who founded the company that markets Proactiv, told People magazine he is confident in Bieberâ€s potential to bring more attention to the brand.

“Justin has millions of fans of all ages and followers online where our consumers spend a lot of their time,” he said.

Indeed Bieber may be the perfect spokesperson for Proactive since he has a primarily teenaged audience and is a teenager himself. Perhaps young guys and girls at a tough age skin-wise will relate more to a 16-year-old star who not only appeals to them but can be seen as going through similar skin problems. The only thing we wonder about is if the smooth, baby-faced singing phenomenon has ever even had a pimple that required Proactivâ€s products. Let’s be honest, most of the celebrity “before” shots are of  a single bump that has to be magnified 10 times to be seen in the first place. Not exactly raging, out of control acne, but we won’t underestimate the power of Bieber when it comes to swaying teenagers. Undoubtedly, even similarly smooth skinned fans will be hoping  for their first spot to feel connected to the pop star, but we’re sure that’s exactly what Proactiv is banking on.
