Arm yourself with a cuticle oil to keep your nail beds in tiptop condition. And, we hate to say it, but it is time to toss your nail-staining dark polish.

Wu says to avoid acetone nail polish remover at all costs. Try RGB Nail Polish Remover which, in addition to coming in convenient and portable packaging, is soy-based and won't strip your nails.

The best thing you can do is to file down your nails where they've split or cracked, and buff out any ridges, Wu advises. Bonus: buffing also gets rid of discoloration.

And switching from darker polish to a lighter one does more than just prevent stains -- Wu says that lighter polish colors make ridges look less noticeable. She also recommends taking biotin, a type of vitamin B that can help nails grow.

No one wants the tops of their hands to look (and feel) like overcooked turkey. Wu says that UV rays break down collagen and elastic tissue as you get older, resulting in a dry, papier mache-esque finish.

Far and away, the easiest thing you can do is eat your protein. "Collagen and elastic tissue are made of protein, so eating protein will help your body produce stronger collagen and thicker skin," Wu explains.

Skip the harsh detergent soap you'll find in most public restrooms. Jaliman recommends keeping a mild cleanser, like Vanicream Gentle Cleanser, with you at all times so you can wash your hands without drying them out. Follow up with a moisturizer (hey, we never said this whole anti-aging thing was going to be low-maintenance).

Kat Burki Hand Therapy uses a blend of cold-pressed oils and arnica, lavender and calendula to hydrate and calm skin. Jaliman also recommends moisturizers with hardcore hydrating ingredients like ceramides and hyaluronic acid.

Don't forget your hands when you slather on your nightly combo of serums and potions. Jaliman says to alternate between a product with retinol and a product with peptides to stimulate collagen production.

To make things easy, multipurpose the facial products you already have and apply them to the backs of your hands. Jaliman recommends Neutrogena Rapid Wrinkle Repair Night Cream for retinol, and Olay Regenerist Deep Hydration Regenerating Cream for your dose of peptides. You can even use prescription-strength retinoid products, like Renova, on your hands.

Wu also recommends paraffin treatments to keep hands soft and non-crepey, which she does once a week in the winter.
