Colors are limited and only while supplies last.
MAC Cosmetics is celebrating National Lipstick Day on Saturday, July 29, with a free tube at U.S. stores.
Makeup lovers will be able to choose from a limited amount of colors which may differ from store to store.
Over two decades ago drag superstar RuPaul posed for MAC's Viva Glam campaign in which all proceeds sold of that product went into the company's AIDS Fund.
For the free lipstick, no purchase is necessary, but they are only available while supplies last.
Glamour Magazine says the MAC lip colors are normally priced at $17 and will be given away at storefronts and other retailers that sell their products, including Ulta.
