I'm sure it hasn't escaped your attention that Earth Day (April 22) is this week. But it is ALSO the 10th anniversary of Juicy Tubes. And Lancome is doing several things to celebrate both.

First of all, they've launched (limited edition) Juicy Tubes 100% Natural Origin. The formula includes Hungarian honey, royal jelly extract, beeswax, and shea

The prize is a brand new MAC Springshine blush ombre (from Spring Forecast), a brand new Lipstick Queen Butterfly Ball Lipstick in Goodbye, and a brand new MAC

Amazing giveaway this week, readers. Tria, makers of at-home skin-treatment devices, asked if I'd like to give away one of their new Skin Clarifying anti-acne systems. It's a $395 prize, including the Clarifying Blue Light device as well as Clarifying Foam Cleanser (AHA/BHA pre-treatment cleanser), Rebuilding Complex (post-treatment serum), and a Clarifying Cartridge (which sounds like a battery, and has

Lancome recently released 8 shades of their new, moisturizing Color Design Matte lipstick, and I think they're pretty fabulous. (See swatches here.)

So when Lancome asked me if I'd like to give a set away, I jumped at the chance. This week's giveaway will have two winners, who will each receive 4 lipsticks. I will try to accommodate the shade preferences

Senna Cosmetics is the brainchild of professional makeup artist (and brow guru) Eugenia Weston.  I first encountered the brand on discount makeup retailer BeautyCrunch — and as far as I can tell, the general population can only buy their products online (Senna's own website, ShopNBC, and BeautyCrunch).  There are also a few Senna salons and boutiques in California, if you

The winner will receive up to $40 of
