Ulta’s 21 Days of Beauty just kicked off: the retailer’s legendary biannual sale where shoppers can secure the best beauty deals of the season (and beyond, tbh). 

The event spans three weeks, starting on Sunday, March 14, and wrapping up on Saturday, April 3. During this timeframe, cult-status makeup and skincare products — from household and budding brands — are half off. In this case, you don’t want to ponder your splurge without haste, as deals expire after 24 hours. This year, shoppers can also enjoy mobile app-exclusive beauty deals beyond the site’s curation.
