20s: Bright Eyes
Bright shades are in this summer. Expect to see lots of greens, blues, and purples on lids, says Landy Dean, a New York-based makeup artist. Use bright eyeliner paired with a matching eye shadow like Jessica Alba's teal version. Skip the mascara and lower lash liner for a more modern vibe.

20s: Hot Manis
Paint on a few coats of summer's hot, neon nail hues instead of the usual pale pinks or classic reds you've been using all year. To get a look similar to Ciara's, try China Glaze in Pool Party. Two coats give you a muted matte finish, or swipe your favorite top coat on for a shiny finish.

30s: Extreme Smoky Eye
Kick your smoky eye up a notch by trying a smudging technique like Victoria Beckham. Pick a highly pigmented matte color like MAC Eye Shadow in Carbon. Apply to your upper lids and, using a moist cotton swab, gently smudge the shadow past your lid into a cat-eye point. Top off your smoky eye with nude lips and bronzed cheeks for a dramatic evening look.
30s: Vibrant Lips
Match your lipstick shade to your skin tone this summer. Dean says those who have golden skin tones should wear an orange-red shade and those with neutral tones should opt for a classic red in a semimatte, cream texture. Keep the rest of your look simple with a light coating of mascara.

40s: Wow Lashes
To create a more youthful look, you don't need to cake on tons of makeup. Instead, perk up your eyes with a reflective under-eye concealer and big lashes. Apply a lash-enhancing treatment like StimuLash Fusion Intensive Night Conditioning Lash Enhancer to get thicker, fuller lashes overnight. In the morning, go for a formula with tons of volume, like Revlon Grow Luscious by Fabulash.

40s: Bright Eyes and Lips
Typically, when you wear red lipstick you tone down the rest of your look, but this summer all muted rules are off! Match your bright lips with an even brighter eye shadow to make your skin really glow. Gwen Stefani's heavy black liner brings out her blue eyes without clashing with her red-hot lips.

50s and Beyond: Hazy Eye with Contoured Cheeks
For a classic look, sport a subtle, hazy eye with contoured cheeks. Dean recommends curling the eyelashes and using several coats of mascara to define and lift your eyes, without making them look heavy. Then, use a palette like Givenchy Le Prisme Mono Eyeshadow in Hip Grey to lightly shade your lids.
To sculpt cheeks, Dean says to use a cream blush high on the cheekbones to highlight your face. Try Clarins Instant Smooth Compact Highlighter in Natural for a healthy, natural-looking glow.
