It's great when your beauty products are not only economical, but also can serve other purposes than the one it's meant for. Invest in some inexpensive products that will go the distance this winter. First, lip balm is a must in winter when chapped lips are common. Most everyone has a jar or tube on hand to keep lips from cracking and flaking. But did you know it's also great for protecting other areas that tend to chap and get dry, like knuckles and even windblown cheeks? Just smooth the stick or a bit from the pot across your knuckles or dry cuticles to add a little moisture to hands. Take a bit on your finger and smooth across cheeks to soothe windburn. Clear polish is great for adding shine to nail polish colors or giving nude nails a little gleam. But with the hot tights trend this winter, keep some on hand to stop runs in their tracks. Hairspray can also work well in a pinch. Q-Tips aficionadas should keep those cottony sticks out of their ears and in their makeup kits. They're great for applying eyeshadow when the applicator from the compact gets old, and they're perfect for smudging eyeliner or shadow.
