Supermodel Cindy Crawford shares her tips on how to preserve a youthful look, and no, they don't include Botox. Plus: tennis star Serena Williams' at-home manicure and reality star Kim Kardashian's favorite products to create her famous smoky eyes.

Keep looking youthful like Cindy Crawford

The supermodel told InStyle magazine her secrets of looking youthful at 44: according to Crawford, the right hair color is one of the essentials to a young look and should be dimensional, not flat. For her skin, she uses Microderm once a month, a procedure that removes dead cells and reduces dark spots by light abrasion. To keep her lips looking full, she makes sure she always uses lipliner and adds some shimmer for extra volume.

Crawford also has an anti-aging skincare line called Meaningful Beauty, which she sells online: http://www.meaningfulbeauty.com

Save money doing your own manicure like Serena Williams

YouTube tutorials make it easy to be your own nail artist, but tennis champion Serena Williams is taking things one step further, heading to beauty school in Florida several times a week to become a nail technician. She told People magazine that her favorite styles for a manicure are a classic red, pink or yellow for spring, or the minx print she wore at the Australian Open.
