How to look and feel your best at any age.

Age is just a number, but there's no shame in wanting your skin to look a little more plump, dewy, and line-free. We asked makeup artists, dermatologists, and other experts to spill the top tricks and tips they have to reverse some of the earliest signs of aging—fast. These are the 20 ways you can look and feel your best at any age.

AGE-DEFYING SECRET COSMETIC SURGEONS DON'T WANT YOU TO KNOW

1. CHOOSE LIGHTER LIPSTICK

Dark shades can be unflattering on mature skin because lips get thinner with age, explains makeup artist Matin Maulawizada, who works with celebrities like Angelina Jolie. To keep lipstick from looking too severe, choose rosy reds or flesh-colored shades, and stay away from peaches and oranges, which can make teeth appear yellow. And remember, swiping on lipstick without other makeup can make you look older than if you wear no makeup at all.

2. SWEEP BLUSH UP HIGH

For an instant cheek lift, place your blush brush at the highest point of your cheekbone and apply color in a circular motion, advises makeup artist Sandy Linter, who works with Elizabeth Hurley. Go for warm pinks, apricots, or bronzes since they create less contrast.

3. LIFT YOUR EYES WITH PENCIL

If you've been using liquid eyeliner for years—or even no eyeliner at all—it's time to try a creamy and soft eyeliner pencil. The softness of a classic kohl or gel pencil enlarges the eyes more than liquid liners do. To reverse droopy-looking lids, blend the liner up at the outer corners with a Q-tip or flat eyeliner brush. We like L'Oréal Paris Never Fail Eyeliner, which even comes with a built-in sharpener.

4. INVEST IN THE RIGHT CONCEALER

Cover-up can be tricky to apply; many formulas sink into crevices, emphasizing every fine line. To get the most coverage with the least product, try "camouflage," a dryer form of concealer that can take years off of your face, says Maulawizada. It doesn't contain as much oil as regular concealer, so it won't move, and it's better at hiding sun spots. Try Laura Mercier Secret Camouflage.

Grab your favorite highlighter, bronzer, and/or contour kit: it's time to define that jawline and give yourself the high cheekbones of your dreams. "Highlight the areas you want to bring out," says Chanel celebrity makeup artist Kara Yoshimoto Bua. "Highlighting with a powdery shimmer highlighter on dry wrinkled areas will emphasize it, but using a moisturizing balm to increase the feeling of dewy skin look healthy and can bring a youthful healthy glow." As for contouring, Bua says it will help reduce the pouch that sometimes appears near the jawline and lift cheekbones when you blend correctly and make sure not to apply too much of it.

6. CHOOSE MOISTURIZING FOUNDATION

Piling on layers of powder will accentuate fine lines and wrinkles and make skin look dry. This is why Bua warns against using thick powder or heavy-duty foundation. "Like a powdery highlight, too much thick foundation and powder on dry or wrinkled skin can make your skin look older," she say. "I would opt for a more moisturizing foundation to add a healthy tone and glow and even out skin without building up a heavy layer." We like Armani Luminous Silk foundation and Laura Mercier Silk Creme Photo Edition foundation.

7. SUPERSIZE YOUR SUNGLASSES

By now you know how damaging the sun can be, so besides coating on sunscreen, shield yourself with chic accessories. Swap your thinly rimmed aviators for oversize frames and you'll get more protection around your eyes, which wrinkle first, says Boston dermatologist Ranella Hirsch. And don't forget a hat: "Buying a five-dollar fedora now will save you $10,000 with me later," adds Hirsch. Throwing on a scarf can also help prevent sun spots in the décolleté area.

8. STOCK UP ON OLIVE OIL

Extra-virgin olive oil contains fatty acids similar to those found in our skin and is an incredibly gentle moisturizer. If you have skin that's dry and sensitive from overloading on harsh face and eye anti-agers, bring your skin-care regimen to a halt, says Jessica Wu, an L.A.-based cosmetic dermatologist, and slather on a thin layer of unflavored oil at night instead.
