TIP: DO NOT SURRENDER EYELINER.

If you do nothing else on your face -- bare complexion, dry glossless lips, nude cheeks -- at the very least you have to wear eyeliner because it has the highest impact for the lowest investment. However, dark black, thickly applied eyeliner will make tired eyes look even more tired. Opt instead for a powder eyeliner in a dark brown or off-black that will allow you to simply fill in your lash line. Powder liner can be applied with an angled brush, but a "pencil" powder eyeliner like L'oreal's is so much more convenient.
