Outdated Trend

Neon Nails
Fluorescent lights don't flatter our complexion—and neon shades on our nails don't help, either. For 2010, it's a softer, gentler nail color we crave. The spring colors from Yves Saint Laurent, Maybelline New York, and Essie (to name a few) include gorgeous pastel pink, blue, and lilac polishes. But beware: Matching pastel shades on hands and feet can be "a little nauseating," says Ji Baek, owner of the Rescue Beauty Lounge nail salons in New York City. The experts recommend keeping nails short, and wearing a light shade on the hands and a richer version on toes. Until the new spring colors hit shelves in February, try the periwinkle Revlon Nail Enamel in Not So Blue-Berry, the pale purple OPI Nail Lacquer in Do You Lilac It?, and the aptly named Rescue Beauty Lounge polish in Pepto Pink.

Winged-Out Liquid Liner
Leave the long, black wings to the birds this season. While a tiny uptick of liner at the eyes' outer corners is flattering (it makes eyes look lifted), extreme elongation (à la Amy Winehouse) looks dated. What feels right now: a thin, wing-free strip of black cream liner paired with bright shadow colors. At the spring Carolina Herrera show, makeup artist Diane Kendal drew the black cream just along the upper lashes, dusting sparkly gold shadow over the lids. At Michael Kors, makeup artist Dick Page chose amethyst shadow, and applied black liner along the inner rims of the eyes and the lash lines.

Overdone '80s Makeup
Major color on the eyes and lips is over, but focusing all the brightness just on the lips looks fresher than ever. So, that's big color, lips only. Need proof? Check out the brilliant orangey-red kissers at Prada and Giambattista Valli. Apply vivid lipstick shades to just the center of the mouth, then spread the color around with your finger so the edges don?t look severe.When your lips are this bold, you don't need much more than mascara and a bit of soft blush.

Matte Nail Polish
As quickly as this trend appeared , it's now on the way out. And good riddance, because matte manicures aren't nearly as flattering as shiny ones. Instead, we're celebrating shine in 2010—particularly in the form of a glossy shade of taupe. Brownish grays reigned at the spring shows this season, appearing at Marc Jacobs, Proenza Schouler, Hervé Léger, and Chanel.

Black Lipstick
It started on our nails, then our lips—but it's time to deep-six the goth-chick look for good. This season, it's all about pretty, glittery gloss. "Coral is gorgeous with olive skin," says makeup artist Chrisanne Davis.Baby pink glosses are pretty on pale skin , while rosy pinks look great on medium to darker complexions.

Intensely Dark Brows
It's time to lighten up and embrace natural-looking brows. If you're a blonde or a redhead, use a powder one shade darker than your brows. If you're brunette, go a shade lighter. Makeup artist Diane Kendal likes to apply the powder with an angled eyebrow brush, starting at the inner corners and feathering it out in short strokes. Set the color with clear brow gel or clear mascara.

Brown-Based Blush
Get ready for something more flushed this spring.Loves the bold pinks and oranges (check out Louis Vuitton's spring show for an extreme version of this look). To keep strong colors from looking fake, the pros suggest topping them with highlighter (we recommend Benefit High Beam Luminescent Complexion Enhancer), then blending like crazy. "You should see no distinct edges," says makeup artist Dick Page. "I cringe when I see these colors turn into racing stripes." Bluish pink is amazing on fair complexions, while intense red blush looks robust on medium skin. Peaches are prettiest on olive coloring,and deep, rosy pinks flatter darker tones.
