Shoppers, clear your medicine cabinets. Ulta's beloved 21 Days of Beauty sale is back, and you know what that means: three weeks of half-off promos on the retailer’s best-selling, top-rated makeup, skin care, body care, fragrance, and more. If there’s one thing better than scoring a good beauty deal, it’s 21 consecutive days of deals on all your favorite products.

If this is your first encounter with Ulta's legendary mega sale, here's how it works: For 21 glorious days, you can shop a selection of Ulta’s most popular products at 50% off. The catch? Each deep deal is live for just 24 hours. So you’ll have to consult our list of R29 editor-approved products to see which day they're going to be on sale and allocate your pennies accordingly.

Ulta has also added a host of newcomers to the fall 2023 roster of standby sale goods (labeled "First Time Steals" on the site) including Peace Out's blemish patches, Tarte's cream blushes, and Fenty Beauty's dual highlighters all during Week 1 of the sale.

Scroll on to see exactly what we think is worth purchasing from Ulta's 21 Days of Beauty sale, going on from August 27 through September 16. And check back here weekly to see a host of new beauty products on sale for Week 2 and Week 3.
