Fashion Week in New York always attracts the same droves of photographers, editors, socialites, and models year after year. At least, they all seem the same to me. The only interaction I typically have with the big white tent in Bryant Park is in shuffling to the other side of the street to avoid being pummeled by a pack of paparazzi and tourists. This time around, I was able to get a behind-the-scenes peek at the models getting prettied for the Abaete Fall ’09 fashion show.

The collection was inspired by post-French Revolutionary “Les Incroyables,” and the makeup for the show drew on this theme to create an “Old World masculinity meets Modern Day femme” look. Though fashion was the focus at the front of the house, tarte was the star of the beauty goings-on backstage. Celebrity makeup artist Tina Turnbow dressed the models in monochromatic, dewy complexions with a touch of color. An essential element for achieving a flawless finish (particularly on acne-prone adolescents) was the Eraser 4-in-1 Natural Concealer.

I bought my first wand of tarte’s special concealer years ago, when spending $19 on blemish cover-up was truly a splurge. The main difference between this product and other concealers is that it blends in so naturally it can do the job anywhere: on dark under-eye circles, over swathes of red skin, or as an eyeshadow base.  As you twist one end of the purple portable tube, it makes a clicking sound and squirts a small amount of flesh-colored fluid onto the applicator brush. I’ve found that it is best to click sparingly because a little bit of the silken potion goes a long way.

The smoothing power within tarte’s concealer comes from silicone, the same component found in many foundation primers. There’s also a cluster of tarte’s signature “skinvigorating” ingredients, including the antioxidant-rich cucumber extract, aloe leaf extract, and vitamins C and E. Arnica and chamomile extracts soothe irritated skin and reduce redness. In contrast to drying concealers laced with salicylic acid, tarte’s formula includes olive oil and safflower seed oil to deliver deep moisturizing benefits to the skin.

Not only is it a breeze to blend in and pat dry, but it also has surprising staying power for how sleek its texture is. Because of the high liquid content of the formula, it seems ideal for lightening shadows under the eyes. I have never run into problems with caking or creasing, as with certain other concealers that result in a frustrating battle between my moisturizer to help blend and a tissue to help remove stubborn remnants. Tarte spares me all that trouble.

And now that it has made an appearance on the runway at Fashion Week, tarte’s magic eraser is both functional and fashionable.
