Being in your 40s is fabulous in its own right: You know who you are, you've got plenty of successes under your belt and you've still got a lot to look forward to. Make this decade even more fabulous with a few small tweaks to your daily life. Here, six habits that'll make you look and feel radiant.

1. Don't Hesitate to Exfoliate

Exfoliating two to three times a week is an easy way to look more luminous. By using a sugar scrub or chemical exfoliant, you'll help your skin shed unwanted dry, dull skin cells to reveal smooth, younger-looking skin.

2. Get Your Glow On

With its combined abilities to moisturize, protect skin from the sun and make you glow, Aveeno's Positively Radiant Daily Moisturizer, $14.99, is as deft a multi-tasker as you are. It's been clinically proven to improve skin's tone and texture, while reducing brown spots, dullness and blotchiness. In other words: It'll let your naturally radiant skin shine through.

3. Reach for the Retinol

Here's another workhorse to add to your skin care arsenal. Retinol, a concentrated version of vitamin A, helps smooth out skin and fight wrinkles by boosting collagen production. Add it to your nightly routine before applying your favorite moisturizer.

4. Schedule Some "Me Time"

Squeezing a spa day or a trip to the nail salon -- or heck, even a solo coffee date -- in between work and family obligations can seem impossible. Still, try to put some "me time" on your schedule. Regularly pressing pause on your hectic life will give you a much-needed chance to relax and reset, no matter how fleeting those moments may be.

5. Fill Your Plate With Fiber

Fiber is an essential part of any woman's diet, but it can be especially beneficial for women in their 40s. Not only does it help boost metabolism, which tends to slow with age, it also promotes a healthy heart. To work fiber into your daily diet, plan meals that are rich in vegetables and whole grains.

6. Go to the Mats

We tend to lose flexibility as we age, so it becomes increasingly important to keep your muscles limber in your 40s. Yoga helps build strength and flexibility while giving you some peace of mind, so go ahead and get "om" with it.
