It's a great week to be a beauty-lover. Ulta's 21 Days of Beauty sale is one of the year's most exciting beauty events and it is happening now through Thursday, March 27. With a range of daily deals on everything from Live Tinted Huesticks to Tarte's top-rated setting spray and coveted skincare devices from Foreo, we thought the deals couldn't get better.

Plot twist: For the first time ever, Ulta Beauty is offering a slew of Weekly Beauty Steals during the 21 Days of Beauty sale, with discounts of 50% off on top-rated beauty products. The Weekly Beauty Steals are only available through Thursday, March 20 and we've got our finger on the pulse to help you grab the best deals.

Unlike the short-lived daily deals that get refreshed throughout Ulta's 21 Days of Beauty sale, the retailer's first-ever Weekly Beauty Steals will stick around for a full seven days. This week's Ulta steals offer major savings on all sorts of popular products across makeup, fragrance, hair and beyond. Our favorite finds from Ulta's Weekly Beauty Steals section include a rare discount on the Billie Eilish-approved (and insanely viral) Sacheu Peel Off Liner STAY-N Bundle and a 50% price cut on Benefit's Benetint Liquid Lip & Cheek Stain.
