Both.

You're going to buy more than one, so here's how to divide the spoils: Spend on a great lipstick shade that you wear every day. "Lipsticks from department stores are creamier. They can contain extracts or vitamins that are oil-soluble, which you are less likely to find in a budget brand," says Alison Griffin, chairperson for the New York Society of Cosmetic Chemists. Save on lip gloss that you're using for shine, since the depth of color is not crucial. Recommended product: L’Oréal Paris Color Juice Sheer Juicy Lip Gloss ($8.50 at drugstores) adds plenty of shine.
 

The Exception

If you want a bright red lipstick to wear just for the holidays, then head to the drugstore. If you're looking for a rich color from your gloss, you may want to invest in a more expensive one. Recommended product: Bobbi Brown Lip Gloss ($23, bobbibrown.com) pops with color.
